Tratamiento hormonal de la pedofilia: ¿puede curar la pedofilia con la castración química? / Pedophilia hormonal therapy: can pedophilia be cured with chemical castration

Históricamente la sociedad ha rechazado el abuso sexual de menores de 13 años, dictándose leyes al respecto. La justicia luego de un debido proceso condenaba al victimario con reclusión incluso hasta la década del 70-80, con orquiectomía. Los adelantos en neurobiología, endocrinología, sicofarmacología y sicología se consideraron las bases para tratar al pedófilo y someterlo a libertad condicional, ahorrándose el costo financiero de la reclusión de por vida. Diversos países dictaron leyes contra la conducta pedófila. En dicha legislación ejerció gran influencia la promulgación en EE.UU. (estado de Washington "sobre el ofensor sexual" y el dictamen de la Corte Suprema en 1997 en el juicio de Kansas vs Hendricks). En Chile en los 90 el caso del pedófilo apodado "Zacarach" sacó a la luz pública el tema que no se quería ver. En esa fecha se presentó al parlamento un proyecto de Ley para "curar" la pedofilia con acetato de Medroxiprogesterona imitando legislación de EE.UU. Causó sorpresa en el medio endocrinológico que se usara terapia hormonal como "cura" de la pedofilia. Se ha utilizado en varios países la castración química producida por gestágenos o agonístas del GnRH más antiandrógenos (acetato de Ciproterona), para inhibir la secreción y acción de la testosterona disminuyendo líbido y erección. No se ha demostrado que exista curación de la orientación pedófila y existen dudas de la prevención primaria y secundaria de la pedofilia. Pese al adelanto tecnológico en neurociencias para estudio de las zonas vinculadas a la sexualidad, aún no existen marcadores que permitan diagnosticar o pronosticar futuros resultados de la terapia. El tratamiento médico de la pedofilia no garantiza curación ni prevención del delito pedofílico.

Historically, society has rejected sexual abuse of children under 13, with there having been laws enacted in this regard. The judicial system, after a due process, condemned the perpetrator with reclusion and even up until the decades of the 70s and 80s with orchiectomy. Advances in neurobiology, endocrinology, psychopharmacology and psychology were considered the basis for treating the pedophile and putting them on probation, saving the financial cost of imprisonment for life. Multiple countries have enacted laws against pedophilic behaviour. Such legislation was greatly influenced by the enactment in the USA (state of Washington "on the sex offender" and the ruling of the Supreme Court in 1997 in the trial of Kansas against Hendricks). In Chile in the 90s, the case of a pedophile nicknamed "Zacarach" brought to light an issue that nobody wanted to see. Around that time, a bill was presented to Parliament to try and "cure" pedophilia with Medroxyprogesterone acetate, imitating US legislation. It was a surprise in the endocrinological world that hormonal therapy would be used as a "cure" for pedophilia. Chemical castration produced by gestagens or GnRH agonists plus antiandrogens (Cyproterone acetate) has been used in several countries to inhibit the secretion and action of testosterone, reducing libido and erection. It has not been proven that there is a cure for pedophile orientation and there are doubts about the primary and secondary prevention of pedophilia. Despite technological advances in neurosciences for the study of the zones pertaining to sexuality, there are still no indicators that allow for diagnosis or prediction of future results of therapy. The medical treatment of pedophilia does not guarantee cure or prevention of pedophilic crime.

Tratamiento hormonal y sus complicaciones en el paciente con disforia de género / Hormonal treatment and complications in patients with gender dysphoria

RESUMEN Introducción: Las personas con disforia de género sienten incongruencia entre el sexo con el que nacen y aquel al que sienten pertenecer, por lo que necesitan adaptar su cuerpo a este último, y uno de los pilares en el logro de ese propósito es el empleo del tratamiento hormonal cruzado. Objetivo: Identificar los esquemas terapéuticos más empleados en la automedicación y en el manejo especializado, y sus complicaciones en pacientes con disforia de género. Métodos: Se revisaron 78 historias, de las cuales 76 correspondían a transexuales hombre-mujer, atendidos en el periodo 2012-2017 en la Consulta Nacional de Atención Integral a Personas Transgénero. Se recuperó información relacionada con los esquemas terapéuticos utilizados, tanto durante la automedicación como durante el manejo por el endocrinólogo, y las complicaciones. Para el análisis de los datos se obtuvieron distribuciones de frecuencia de las variables cualitativas, media y desviación estándar de las cuantitativas. Resultados: La frecuencia de pacientes que se autoadministraron hormonas antes de comenzar la atención especializada fue de 82,9 por ciento. El medicamento más utilizado en la automedicación fue la cipresta (acetato de ciproterona 2 mg/etinilestradiol 50 µg) en el 90,5 por ciento de los casos. De los tratamientos indicados por el endocrinólogo al inicio de la atención; al 50,0 por ciento se les administró cipresta más androcur (acetato de ciproterona 50 mg) de 1 a 2 tabletas de cada uno, mientras que al 39,5 por ciento estrógenos conjugados asociado a androcur, igualmente de 1 a 2 tabletas de cada uno de estos medicamentos. En cuanto a la frecuencia de complicaciones como consecuencia del tratamiento hormonal, el 40,7 por ciento de los casos tuvo en algún momento niveles elevados de prolactina, al 26,3 por ciento los niveles de triglicéridos se le elevaron luego de iniciada la terapia. Conclusiones: La mayoría de los pacientes acuden por primera vez automedicados. Los medicamentos más utilizados son la cipresta y el androcur. La complicación más frecuente como consecuencia del tratamiento es la hiperprolactinemia(AU)

ABSTRACT Introduction: Persons with gender dysphoria feel incongruity between the sex they are born with and the one they feel they belong to, therefore they need to adapt their body to the latter, and one of the pillars in achieving that purpose is the use of cross hormonal treatment. Objective: To identify the therapeutic schemes most used in self-medication and specialized management, and their complications in patients with gender dysphoria. Methods: Seventy eight medical records were reviewed. Seventy six of them corresponded to male-female transsexuals, assisted in the 2012-2017 period at the National Consultation of Comprehensive Care to Transgender Persons. The study team recovered information related to the therapeutic schemes used, both during self-medication and during the endocrinological management, as well as complications. Frequency distributions of the qualitative variables, mean and standard deviation of the quantitative variables were obtained for data analysis. Results: The frequency of patients who self-administered hormones before beginning specialized care was 82.9 percent. The most commonly medication used in self-medication was cypress (cyproterone acetate 2 mg / ethinylestradiol 50 µg) in 90.5 percent of cases. Out of the treatments indicated by the endocrinologist at the beginning of the care; 50.0 percent were given cypress plus androcur (50 mg cyproterone acetate) of 1 to 2 tablets each, while 39.5 percent conjugated estrogens associated with androcur, also 1 to 2 tablets of each of these medications. Regarding the frequency of complications as a result of hormonal treatment, 40.7 percent of the cases had elevated prolactin levels at some time, and triglyceride levels increased to 26.3 percent after the start of therapy. Conclusions: Most patients who come for the first time, are self-medicated. The most used medications are cipresta and androcur. The most frequent complication is hyperprolactinemia as a consequence of treatment(AU)

Efficacy of acupuncture as adjunctive treatment on infertility patients with polycystic ovary syndrome / 中国针灸

<p><b>OBJECTIVE</b>To observe the efficacy differences between acupuncture combined with medication and medication alone for infertility patients with polycystic ovary syndrome (PCOS).</p><p><b>METHODS</b>According to random number table, a total of 60 infertility patients with PCOS were randomly assigned into an observation group and a control group, 30 cases in each one. The patients in the control group were treated with diane-35 from the 3rd day into menstruation, and one menstrual cycle was taken as a session of treatment. At the same time of using diane-35, the patients in the observation group were treated with acupuncture at Guanyuan (CV 4), Qihai (CV 6), Sanyinjiao (SP 6), Zusanli (ST 36), Zigong (EX-CA 1), Shenshu (BL 23), Pishu (BL 20), Weishu (BL 21) and Ganshu (BL 18) during non-menstruation period; the acupuncture was given once every two days, three treatments per week. The patients in both groups were treated for two sessions. The basic sex hormone and body mass index (BMI) were compared between the two groups before and after treatment. After ovulation induction treatment, the endometrial thickness, amount of mature follicle, ovulation rate, clinical pregnancy rate, occurrence rate of ovarian hyperstimulation syndrome (OHSS) and the number of early spontaneous abortion were compared between the two groups during ovulation.</p><p><b>RESULTS</b>After treatment, the luteinizing hormone (LH), testosterone (T) and BMI reduced in the observation group (all <0.05), while only LH reduced in the control group (<0.05). The reducing of estradiol (E), T and BMI in the observation group was more significant than that in the control group (all <0.05). The ovulation rate was 93.3% (28/30) in the observation group, which was higher than 80.0% (24/30) in the control group (<0.05). The rate of clinical pregnancy was 43.3% (13/30) in the observation group, which was higher than 33.3% (10/30) in the control group (<0.05). The differences of endometrial thickness, amount of mature follicle, occurrence rate of OHSS and number of early spontaneous abortion were not significant between the two groups (all >0.05).</p><p><b>CONCLUSION</b>Acupuncture as adjunctive treatment could improve BMI, reduce the levels of LH, E and T, increase ovulation reaction and effectively shorten reproduction cycles in infertility patients with PCOS.</p>

Low estrogen doses normalize testosterone and estradiol levels to the female range in transgender women

OBJECTIVE: The ideal dosage of cross-sex hormones remains unknown. The aim of this study was to evaluate the luteinizing hormone, follicle-stimulating hormone, testosterone, estradiol and prolactin levels after low-dose estrogen therapy with or without cyproterone acetate in transgender women. METHODS: The serum hormone and biochemical profiles of 51 transgender women were evaluated before gonadectomy. Hormone therapy consisted of conjugated equine estrogen alone or combined with cyproterone acetate. The daily dose of conjugated equine estrogen was 0.625 mg in 41 subjects and 1.25 mg in 10 subjects, and the daily dose of cyproterone acetate was 50 mg in 42 subjects and 100 mg in one subject. RESULTS: Estrogen-only therapy reduced the testosterone, luteinizing hormone and follicle-stimulating hormone levels from 731.5 to 18 ng/dL, 6.3 to 1.1 U/L and 9.6 to 1.5 U/L, respectively. Estrogen plus cyproterone acetate reduced the testosterone, luteinizing hormone and follicle-stimulating hormone levels from 750 to 21 ng/dL, 6.8 to 0.6 U/L and 10 to 1.0 U/L, respectively. The serum levels of luteinizing hormone, follicle-stimulating hormone, testosterone, estradiol and prolactin in the patients treated with estrogen alone and estrogen plus cyproterone acetate were not significantly different. The group receiving estrogen plus cyproterone acetate had significantly higher levels of gamma-glutamyltransferase than the group receiving estrogen alone. No significant differences in the other biochemical parameters were evident between the patients receiving estrogen alone and estrogen plus cyproterone acetate. CONCLUSION: In our sample of transgender women, lower estrogen doses than those usually prescribed for these subjects were able to adjust the testosterone and estradiol levels to the physiological female range, thus avoiding high estrogen doses and their multiple associated side effects.

Comparison of Drospirenone- with Cyproterone Acetate-Containing Oral Contraceptives, Combined with Metformin and Lifestyle Modifications in Women with Polycystic Ovary Syndrome and Metabolic Disorders: A Prospective Randomized Control Trial / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>While combined oral contraceptives (COCs) are commonly used to treat polycystic ovary syndrome (PCOS), comparative data regarding metabolic effects of different progestogens on this patient population are missing. This study aimed to compare the different effects of drospirenone (DRP)-containing COCs with cyproterone acetate (CPA)-containing COCs, combined with metformin and lifestyle modifications in women with PCOS and metabolic disorders.</p><p><b>METHODS</b>Ninety-nine women with PCOS and a metabolic disorder between January 2011 and January 2013 were enrolled into this prospective randomized clinical trial. Participants were randomized into two groups such as DRP-containing COCs, and CPA-containing COCs. Participants took COCs cyclically for 6 months, combined with metformin administration (1.5 g/d) and lifestyle modifications (diet and exercise). Clinical measures and biochemical and hormone profiles were compared. Comparisons for continuous variables were evaluated with paired and unpaired Student's t-tests. The Wilcoxon signed rank test was used when the data were not normally distributed. Analysis of covariance was used to control for age, body mass index (BMI), and baseline data of each analyzed parameter when compared between the two groups.</p><p><b>RESULTS</b>A total of 68 patients have completed the study. The combination regimen of COCs, metformin, and lifestyle modifications in these patients resulted in a significant decrease in BMI, acne, and hirsutism scores when compared to baseline levels in both groups (P < 0.05). Blood pressure (BP) was significantly different in the CPA group when compared to baseline (75.14 ± 6.77 mmHg vs. 80.70 ± 5.60 mmHg, P < 0.01), and after 6 months of treatment, only the change in systolic BP was significantly different between the two groups (4.00 [-6.00, 13.00] mmHg vs. -3.50 [-13.00, 9.00] mmHg, P = 0.009). Fasting glucose, fasting insulin, and homeostasis model assessment-insulin resistance decreased significantly in the DRP group (5.40 ± 0.41 mmol/L vs. 5.21 ± 0.32 mmol/L, P = 0.041; 13.90 [10.50, 18.40] μU/ml vs. 10.75 [8.60, 13.50] μU/ml, P = 0.020; 3.74 [2.85, 4.23] vs. 2.55 [1.92, 3.40], P = 0.008) but did not differ between the two groups. While individual lipid profiles increased in both groups, no statistically significant difference was observed.</p><p><b>CONCLUSIONS</b>DRP-containing COCs combined with metformin and lifestyle modifications could better control BP and correct carbohydrate metabolism in women with PCOS and metabolic disorders compared with CPA-containing COCs.</p><p><b>TRIAL REGISTRATION</b>Chinese Clinical Trial Registry, ChiCTR-TRC-11001143; http://www.chictr.org.cn/showproj.aspx?proj=8395.</p>

Changes of serum TOS and TAS levels and their association with apolipoprotein(a) in patients with polycystic ovary syndrome and infertility / 南方医科大学学报

<p><b>OBJECTIVE</b>To investigate changes of serum total oxidation status (TOS) and total antioxidant status (TAS) and their association with apolipoprotein (a) [Apo(a)] in patients with polycystic ovary syndrome (PCOS) combined with infertility.</p><p><b>MWTHODS</b>Ninety patients with PCOS and infertility were selected as the study group, including 45 patients treated with antioxidants combined with Diane-35(group A) and 45 with Diane-35 therapy only (group B), with 45 healthy volunteers with normal menstruation and normal dual phase basic body temperatures as the control group. Serum TOS of the participants was determined by dual xylenol orange method, and serum TAS was determined with ABTS method; plasma Apo(a) level was determined by dual wavelength immune transmission turbidity method.</p><p><b>RESULTS</b>Before treatment, serum TOS, OSI, and Apo(a) levels were significantly higher and TAS level was significantly lower in the study group than in the control group (P<0.05). Serum TOS, OSI, and Apo (a) were significantly lowered and TAS was significantly increased in group A after the therapy as compared with the levels before therapy and the levels in group B. The rate of natural recovery of menstruation was significantly higher and the incidence of cardiovascular disease was significantly lower in group A than in group B (P<0.05). Pearson correlation analysis showed that serum TOS and OSI were positively correlated with plasma Apo(a) (r=0.524 and 0.531, P<0.05), and serum TAS was negatively correlated with plasma Apo(a) (r=-0.519, P<0.05).</p><p><b>CONCLUSION</b>Antioxidant therapy can lower TOS, OSI and Apo(a) levels and increase TAS level to lessen oxidative stress, improve the prognosis, and reduce the risks of cardiovascular disease in patients with PCOS and infertility.</p>

Efficacy comparison between electroacupuncture and dyne-35 in treatment of polycystic ovary syndrome / 中国针灸

<p><b>OBJECTIVE</b>To compare the difference in clinical efficacy on polycystic ovary syndrome (PCOS) between electroacupuncture (EA) and dyne-35 and to explore the effect mechanism.</p><p><b>METHODS</b>Sixty-five patients were randomized into an EA group (33 cases) and a western medication group (32 cases). In the EA group, the selected acupoints were Danzhong (CV 17), Qimen (LR 14), Zhongwan (CV 12), Tianshu (ST 25), Guanyuan (CV 4), Zigong (EX-CA 1), Sanyinjiao (SP 6), Zusanli (ST 36) and Taichong (LR 3), etc. After the arrival of qi, electric stimulation was attached to the acupoints for 30 min. The treatment was given 3 times a week. In the western medication group, dyne-35 was prescribed on the 5th day of natural menstruation or withdrawal bleeding, one tablet a day, continuously for 21 days. The treatment cycle was 3 months in the two groups. The menstrual condition, body mass, body mass index (BMI), serum testosterone (T), luteinizing hormone (LH), follicle-stimulating hormone (FSH) and LH/FSH were compared before and after treatment in the two groups. The clinical efficacy was assessed in the two groups.</p><p><b>RESULTS</b>The total effective rate was 90.6% (29/32) in the EA group and was 93.3% (28/30) in the western medication group. The efficacy was similar in the two groups (P > 0.05). After treatment, the levels of LH and LH/FSH were all reduced significantly in the two groups (all P < 0.01). After treatment, T level in serum was reduced apparently in the western medication group (P < 0.05). Before and after treatment, the differences in body mass and BMI in the EA group were more significant than those in the western medication group (P < 0.01, P < 0.05).</p><p><b>CONCLUSION</b>EA is the effective method for PCOS, similar to that of dyne-35. The effect of it for weight loss is superior to dyne-35 and no apparent adverse reactions happen. The effect mechanism of EA is related to the regulation of serum sexual hormone levels and their ratio, as well as to the regulation of body lipid metabolism.</p>

Tratamento hormonal da acne baseado em evidências / Hormonal treatment of acne based on evidence

Este trabalho de revisão apresenta o tratamento hormonal da acne baseado em evidências. O trabalho resume a clínica, a classificação, a fisiopatologia e a etiologia da acne. A avaliação de estudos selecionados mostrou que o tratamento hormonal da acne deve ser complementado por tratamento cosmiátrico, e não está indicado para gestantes ou mulheres com planos de engravidar. A primeira escolha para esse tratamento são os contraceptivos hormonais orais, pois são efetivos e seguros para tratamento da acne e também para anticoncepção. Após tempo estabelecido, se o resultado for insatisfatório, outro medicamento, como acetato de ciproterona ou espironolactona, deve ser adicionado. A finasterida é o medicamento indicado para acne de origem idiopática, e a flutamida apresenta efeitos colaterais significativos, não constituindo indicação segura até o momento.

This review shows the hormonal treatment of acne. The review summarizes the clinical aspects, classification, physiopathology and etiology of the acne. The evaluation of selected papers showed that hormonal treatment of acne with hormones has to be complemented by esthetics treatment and is not prescribed for pregnant women or those who want to get pregnant. The first choice of treatment is the hormonal oral contraceptive one, because it is effective and safe for treatment of acne and also for contraception. After an established period with unsatisfactory results, other medicines, such as ciproterone acetate or spironolactone, can be added. The finasteride is prescribed for idiopathic acne and flutamide has many relevant side effects and is also not safe.

Tratamento hormonal do hirsutismo baseado em evidências / Evidence-based hormonal treatment of hirsutism

A revisão de estudos baseados em evidências mostra o melhor tratamento hormonal para o hirsutismo. Inicialmente, resumiu-se a fisiologia do pelo, caracterizou-se o hirsutismo, suas variantes e suas causas. Revelou-se que o tratamento hormonal do hirsutismo deve ser complementado pelo tratamento cosmético e não deve ser indicado para mulheres grávidas ou que desejam engravidar. A primeira opção é o contraceptivo hormonal oral, seguro para contracepção e eficaz para tratamento do hirsutismo. Após tempo estipulado, não ocorrendo resposta satisfatória, associar acetato de ciproterona ou espironolactona. A finasterida é indicada para hirsutismo idiopático e a flutamida, devido aos efeitos colaterais, ainda não é opção segura

An evidence-based review shows the best hormonal treatment of hirsutism. This paper summarized the physiology of the hair, characterized the hirsutism, its variants and etiologies. The study revealed that hormonal treatment of hirsutism has to be complemented by esthetic treatment, and it is not recommended for pregnant women or for those who want to get pregnant. The first option is hormonal oral contraceptive, which is safe for contraception and effective for treatment of hirsutism. After a established period of treatment, if good results do not occur, the association of cyproterone or spironolactone is recomended. Finasteride is the treatment of idiopathic hirsutism, and flutamide is not a safe option due to its side effects

Comparison of metformin and cyproterone-estrodiol compound effect on hs C-reactive protein and serum androgen levels in patients with poly cystic ovary syndrome

The aim of this study was comparison of the effects of Metformin and Cyproterone-estradiol compound on serum androgens and highly sensitive C-reactive protein levels. Sixty patients with Poly Cystic Ovary Syndrome [PCOS] were enrolled in this study conducted during a period of 16 months from December 2004 to March 2006. Thirty subjects were in each group and treated with Metformin one gram per day or Cyproterone-estradiol compound 21 days monthly and at the beginning and after 3 and 6 months, weight, height, testosterone, dehydroepiandrosterone sulfate [DHEA-S] and hs-CRP levels were measured. Mean age of patients was 23.5 +/- 8.7 years with the range of 15 to 49 years. In both groups significant decreases in DHEA-S levels and in Cyproterone-estradiol compound group a significant decrease in testosterone levels were seen after 6 months, but there were no significant decrease on hs-CRP levels. Comparison of two groups showed that there were no significant differences in the effects of these two drugs on serum testosterone, DHEA-S and hs-CRP levels. In our study the level of hs-CRP at the beginning of treatment were significantly higher in patients who were overweight and obese. Also we found that Cyproterone-estradiol compound causes significant decrease at the level of hs-CRP in overweight and obese patients. The results of this study are different from those of previous studies about beneficial effects of Metformin on hs-CRP levels but are similar to the results of studies that revealed probably obesity and overweight has important role in inducing inflammation and increasing CRP levels

A case of fulminant hepatic failure due to cyproterone acetate in a patient with cryptogenic liver cirrhosis / 대한내과학회지

Cyproterone acetate is an antiandrogenic drug that has been used in prostatic cancer. The drug is thought to be well-tolerated but has hepatotoxic effects. An 89 year-old man treated with cyproterone acetate 300 mg/d for prostatic cancer presented with a hepatotoxic reaction. Toxic hepatitis was diagnosed and cyproterone acetate was stopped immediately. The patient was treated with supportive management and a corticosteroid, but he died 28 days after administration due to liver failure. A liver biopsy performed after his death revealed the presence of acute hepatitis with cirrhosis. Underlying cirrhosis was not suspected before his death. Ultimately, the case was diagnosed as fulminant hepatic failure due to cyproterone acetate with underlying cryptogenic liver cirrhosis. This case and current literature highlight the hepatotoxic potential of cyproterone acetate and illustrate the importance of clinical surveillance, especially in patients with unrecognized liver disease.

Efeitos do valerato de estradiol associado ao acetato de ciproterona em alguns parâmetros clínicos e da sexualidade em mulheres na pós-menopausa / Effects of estradiol valerate associated with cyproterone acetate on some clinical and sexuality-related aspects in postmenopausal women

Objetivo: Avaliar os efeitos clínicos da terapia estro-progestogênica em pacientes na pós–menopausa, com ênfase nos sintomas de climatério e sexualidade. Métodos: Estudo prospectivo, cego, randomizado, unicêntrico, cruzado e controlado com placebo, com duração de 12 meses consecutivos, feito com 40 mulheres na pós-menopausa (idade média de 52,2 anos) sem nenhuma contra-indicação para terapia hormonal e com útero íntegro, que foram divididas em dois grupos: nos primeiros seis meses de seguimento de estudo, um grupo recebeu valerato de estradiol 2 mg/dia por 21 dias/mês associado com acetato de ciproterona 1 mg/dia nos últimos dez dias (Climene®). O outro grupo recebeu um comprimido por dia, 21 dias/mês de placebo por seis meses. Os tratamentos foram então invertidos e as pacientes foram seguidas por mais seis meses. Para análise estatística o grupo que recebeu terapia hormonal foi referido como Grupo A e o grupo placebo como Grupo B. Avaliou-se a sintomatologia climatérica e a sexualidade. Aplicou-se a análise de variância (ANOVA, crossover) e o teste de McNemar. Rresultados: Nas pacientes do Grupo A, verificou-se redução significativa das ondas de calor e da insônia. No grupo que recebeu terapia hormonal, melhora significativa foi também detectada com respeito ao interesse sexual, na comunicação com o parceiro e na capacidade de obter orgasmo durante a penetração. Para as demais questões não foram detectadas diferenças estatisticamente significativas. Cconclusões: A melhora nos sintomas climatéricos e na sexualidade foram significativas nas mulheres do grupo com terapia hormonal.

Perspectives of contraceptive choices for men.

Apart from condoms and vasectomy, which have several limitations of their own, no other methods of contraception are available to men. Various chemical, hormonal, vas based and herbal contraceptives have been examined and few of them have reached the stage of clinical testing. Promising leads have been obtained from testosterone buciclate/undecanoate, alone or in combination with levonorgestrel butanoate or cyproterone acetate, RISUG, an injectable intravasal contraceptive and a few herbal products, particularly the seed products of Carica papaya. It is feasible that an ideal male contraceptive, that meets out all the essential criteria will be made available to the community in the near future.

Effects of metformin combined with cyproterone acetate on clinical features, endocrine and metabolism of non-obese women with polycystic ovarian syndrome / 华中科技大学学报（医学）（英德文版）

In order to explore the effects of metformin combined with cyproterone acetate (CPA) on the clinical features, endocrine and metabolism of the patients with polycystic ovarian syndrome (PCOS), 50 cases of non-obese PCOS were randomly subjected to CPA (CPA treatment group, n = 25) and CPA+ metformin (n = 25) treatment for 6 months. Before and after treatment the body mass index (BMI), waist : hip ratio (WHR), ovarian volume, serum gonadotrophin, androgen and sex hormone-binding globulin (SHBG) levels, and fasting lipid, glucose and insulin levels were measured. The results showed that all of the parameters in two groups were similar before treatment. After treatment for 6 months in the CPA+ metformin group, BMI and WHR were significantly decreased, while insulin sensitivity was significantly decreased as Compared with those before treatment. In CPA group, no significant changes were found before and after treatment. Combined use of CPA and metformin could result in the reduction of serum androstenedione and increases of serum SHBG levels as compared with the CPA treatment alone. It was concluded that combined use of CPA and metformin could improve the insulin sensitivity, and further suppress the hyperandrogenism in non-obese women with PCOS.

Clinical research on combined therapy of diane-35 with modified yougui pill on polycystic ovarian syndrome / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To investigate the clinical efficacy of integrative traditional Chinese and Western medicine on polycystic ovarian syndrome (PCOC).</p><p><b>METHODS</b>Sixty-three patients with polycystic ovarian syndrome were randomly allocated into 2 groups, 31 patients orally administered with diane-35 in the Western medicine group (WMG) and 32 patients treated with conventional controlled medicine plus modified Yougui Pill in the integrative medicine group (IMG). Changes of relevant hormones and clinical syndromes in patients were detected before treatment, after 3 cyclic treatment and at the 6th cycle after treatment.</p><p><b>RESULTS</b>The levels of relevant hormones and the indexes of B-ultrasonic were obviously improved after treatment in the two groups.

What's more, the normalization of menstruation, ovulation and pregnancy rate in IMG were significantly higher than those in WMG (P < 0.01).</p><p><b>CONCLUSION</b>Diane-35 combined with modified yougui pill in treating polycystic ovarian syndrome not only shows marked short-term effect, but could consolidate the curative effect.</p>

Comparison of clinical improvement between metformin and Diane in women with polycystic ovary syndrome

Metfomin, a biguanide antihyperglycemic drug, has been shown in improvement ovarian function and glucose metabolism in women with polycystic ovary syndrome [PCOS], but results concerning its effects on insulin sensitivity are controversial. Oral contraceptive pills are commonly used in the treatment of PCOS; but like metformin, their influence on insulin sensitivity is not well known. The aim of this study was to compare the clinical improvement between Metformin and Diane in women with polycystic ovary syndrome. This research was a prospective randomized clinical trial study. We randomized 60 [20-49 years old] women with PCOS either to metformin [500 mg] X3 daily for 6 months or to ethinyl estradiol [35 microg] cyproterone acetate [2 mg] oral contraceptive pills [Diane] for 6 months. This study prolonged for 2 years. Results showed that metformin significantly decreased the waist to hip ratio, body mass index [BMI], serum glucose and insulin concentrations and improved menstrual cyclicily hirsutism score and Insulin sensitivity. Diane decreased hirsutism score and improvement in .the menstrual pattern but slight effect in carbohydrate metabolism and increase serum glucose. Metfomin, probably by way of its effects on adipose tissue, leads to reduction of hyperinsulinemia and concomitant improvement; in the menstrual pattern and clinical manifestation hyperandrogenism and therefore, it offers a useful alternative treatment for anovulatory women with PCOS. Dian slight increased in fasting glucose, BMI and Waist To hip ratio but it is an effective treatment for women with hyperandrogenism and hirsutism

Medical Treatment of the Benign Prostatic Hyperplasia

The search for nonhormonal pharmacological agents capable of reducing out flow obstruction caused by benign prostatic hyperplasia (BPH) began in the 1970s when alpha adrenergic receptors were demonstrated within the smooth muscle element of prostatic adenomas, the prostatic capsule, and the bladder neck. Recently, many studies have confirmed that the alpha adrenoceptor blockade sub-jectively and objectively reduces symptoms and urodynamic parameters in bladder outflow obstruction. Very longterm effects of the alpha blockade upon the pro-state are not yet known. There is no direct evidence of a decrease in the stromal smooth muscle bulk or in the total prostate volume after longterm treatment with alpha adrenoceptor blockers in man. The endocrinebased therapies, such as stilbestrol, luteinizing hormonereleasing hormone analogues, antiandrogens flutamide, and cyproterone acetate, have sometimes been used to treat BPH, but with a limited efficacy and prominent sideeffects such as loss of libido, impotence, hot flushes, and gynecomastia. Although it has been shown that some of these therapies may shrink the prostate, the sideeffects are intolerable to most patient. On the other hand, new 5 alpha reductaseinhibiting agents are able to block the effects of androgen within the prostate without a systemic antiandrogen activity. Since the effects of androgens are particularly directed at the glandular element of the prostate rather than at the smooth muscle, the combined use of alphaadrenoceptor blockers and 5 alphareductase inhibitors could theoretically produce an additive effect in the treatment of BPH. The indications of medical treatment for BPH include patients with mild to moderate symptoms, especially if they are reluctant to undergo surgery, and those who are not medically eligible to surgery.
