ABSTRACT
Background: Insulin resistance and hyperinsulinemia may play a role in pathogenesis of PCOS. One of the common therapeutic methods is using insulinsensitizing drugs such as metformin and thiazolidinediones
Objective: The purpose was to determine the effect of metformin and pioglitazone on clinical, hormonal and metabolic parameters in women with PCOS
Materials and Methods: Eighty four women randomly received one of the following for 3 months: metformin [n=28] [500 mg three times a day], pioglitazone [30 mg daily] [n=28] and combination of both metformin and pioglitazone [n=28] [30 mg/day pioglitazone plus 500 mg metformin three times a day]. Hormonal profile, fasting serum insulin, body weight, body mass index, menstrual status and waist to hip ratio were evaluated before and after treatment
Results: Metformin and pioglitazone and combination therapy induced favorable changes in fasting serum insulin, HOMA-IR index, QUICKI, fasting glucose to insulin ratio in women with PCOS. Body weight, BMI, and waist to hip ratio increased significantly after treatment with pioglitazone but the data were similar after administration of metformin or combination therapy. Total testosterone level decreased significantly only after treatment with metformin. After 3 months in patients who received pioglitazone or combination therapy, menstrual cycles became regular in 71.4% and 73.9% respectively. While menstrual improvement happened only in 36.4% of the patients treated with metformin
Conclusion: These findings suggest that insulin-sensitizing drugs induce beneficial effect in insulin resistance and menstrual cyclicity but only metformin ameliorated hyperandrogenemia in women with PCOS. Treatment with combination of metformin and pioglitazone did not show more benefit than monotherapy with each drug alone
ABSTRACT
Background: Cancer antigen 125 [CA-125] is a glyeoprotein biomarker that is used in women with pelvic masses such as endometriosis and maybe is useful in practice of patients suspicious to endometriosis
Objective: The aim of this study was to evaluate the association between preoperative serum CA-125 levels and clinic pathological characteristic in women with endometriosis, and find out the best serum CA-125 levels cut-off in pre and post menopause women
Materials and Methods: Serum CA-125 levels in 87 women aged 21-54 years suspected to endometriosis with pelvic pain, dysmenorrhea, or dyspareunia were measured preoperatively. Also the association between clinic pathological characteristic and serum CA-125 level were analyzed
Results: The mean age of women was 32.22+/-6.91. The mean serum CA-125 level was 49,93+/-4.30 U/rnL.
There was a significant correlation between the endometriosis stage, lesion size, adhesion score and preoperative CA-125 plasma concentration. However, we did not found significant differences in age, marital status, patient's complaints, and pelvic pain associated to Cal25 serum level
The suggested preoperative serum cut-off levels in premenopausal and postmenopausal patients were 37 U/ml and 35 U/ml, respectively
Conclusion: According to the results, preoperative serum CA-125 is an important predictor for patients with endometriosis and it should be taken into consideration when surgical management is suspected, especially if stage of disease, lesion size and adhesion score are undertaken
ABSTRACT
In vitro maturation [IVM] of immature oocytes collected from ovary has been proposed for fertility preservation. In addition, quality of oocytes post IVM is one of the factors determining its developmental competence. By using the non-invasive Polscope system, both meiotic spindle [MS] and zona pellucida [ZP] can be assessed in living oocytes. The aim was to investigate the developmental potential of immature oocytes retrieved from ovarian tissue after IVM, as a method for fertility preservation, in patients with gynecological diseases. The ovarian cortex from 26 patients with malignant and benign diseases [21-45 years old], were obtained directly from collaborating hospitals, and transported to the IVF center on ice. In total 61 immature oocytes were aspirated, of which 18 [29.5%] were degenerated and discarded. The remaining 43 [70.5%] healthy oocytes were cultured in IVM culture media for 48 hr. The rate of maturity was assessed, and the ZP birefringence and MS were imaged with Polscope technology. Overall 43 immature oocytes underwent IVM technology, of which 30.2% reached viable metaphase II [MII] oocytes. The ovarian tissues of 9 [34.6%] women were lacking oocytes at any stage. During polarized light microscopy examination, MS could be visualized only in one of the MII oocytes, but high ZP birefringence's were observed in the majority of the oocytes post IVM [61.5%]. Oocytes maturation post IVM from unstimulated ovaries showed a good developmental competence in gynecologic patients. Further studies should be performed to advance the oocyte maturation program, such as co-culture system, for fertility preservation
ABSTRACT
Isolated fallopian tube torsion is rare and often difficult to diagnose. Definitive diagnosis is always made at laparoscopic or via laparotomy exploration performed for suspected ovarian torsion. Early diagnosis and conservative laparoscopic treatment especially in a reproductive age woman is warranted as a means of preserving fallopian tube integrity and maintaining fertility. Here, we describe a case with isolated right fallopian torsion being managed by conservative laparoscopic surgery
ABSTRACT
Background: Infertility affects about 10-15% of reproductive-age couples. About half the causes of infertility are female related and approximately 40% of the cases are caused by anovulation, mostly in PCO women
Objective: This study was conducted to determine and compare the effects of two drug treatment regimens: higher dose of Clomiphene and a combination of lower dose of cloniiphene and tamoxifen in treating infertile women with PCO
Materials and Methods: The study was a randomized clinical trial conducted on 100 infertile patients who referred to Yazd-Iran Infertility Clinic between the years 2001-2003. The patients were selected who had received at least 3 periods of clomiphene, but no pregnancy had occurred. They were randomly divided into two groups. In the first group, clomiphene was increased to 100 mg and the second group 20 mg of tamoxifen was added to 50 mg of clomiphene from day 5-9 of menstruation cycle. Infertility duration, duration of medicine used, PCT score, endometrial thickness, ovulation, and pregnancy rate were studied in both groups
Results: Ovulation rate in clomiphene group was 54.9%; Tamoxifen + clomiphene group was 73.5% without significant differences in both groups. [PV = 0.053]. Positive pregnancy rate in clomiphene group was 39.2%; clomiphene + tamoxifen group was 61.2% [P value < 0.05], which could be concluded that pregnancy rate was higher in clorniphene/tamoxifen group than in the clomiphene group. The presence of a dominant follicle in the two treatment groups in women between 18-24 was not significant, but in women between 25-39 years was significant [PV= 0.049] [Table III]
Conclusion: The recommendation is to add Tamoxifen to Clomiphene in 35-39 women with 20< BMI <26.99 before the use of gonadotropins treatment in PCOS with or without IUI, because these options have higher risk of multiple pregnancy and ovarian hyperstirnulation syndrome
