ABSTRACT
Objective:To compare the effect of luteal-phase support administration of gonadotrophin-releasing hormone agonist(GnRH-a)on the outcomes of fresh embryo transfer in GnRH antagonist cycles,and explore a more appropriate protocol of luteal-phase support.Methods:A retrospective analysis was performed on the infer-tility patients who receiving in vitro fertilization or intracytoplasmic sperm injection embryo transfer(IVF/ICSI-ET)in the Reproductive Medicine Center of our hospital from January 2018 to December 2021.Our study collected clini-cal data from 674 cycles of infertility patients undergoing fresh cycle transplantation using antagonist regimens.The patients were divided into the control group(n =348)and the observation group(n =326)according to if Gn-RH-a was added to the luteal phase.The patients in control group were given standard luteal support treatment,while the patients in observation group were given multiple-dose GnRH-a 0.1mg to standard luteal support treat-ment after egg retrieval.The general data,ovulation induction and clinical outcome were compared between the two groups.Results:Between the two groups of patients,there was no statistically significant difference in age,years of infertility,body mass index(BMI),basal follicle stimulating hormone(bFSH),days and total amount of gonadotropin(Gn),chorionic gonadotropin(HCG),luteinizing hormone(LH),estradiol(E2)and progesterone(P),the number of retrieved oocytes,MII oocytes,number of embryos,normal fertilization rate,moderate to se-vere ovarian hyperstimulation syndrome(OHSS)rate,abortion rate,live birth rate,multiple pregnancy rate,inci-dence of pregnancy complications,birth weight of offspring,preterm birth rate,and birth defect rate(P>0.05).The implantation rate and clinical pregnancy rate were significantly higher in the observation group compared with control group(P<0.05).Multivariate Logistic regression analysis indicated that age and number of transferred embryos could influence the clinical pregnancy rate(OR 0.958,95%CI 0.917-1.000;OR 1.857,95%CI 1.173-2.942).Conclusions:In fresh embryo transfer cycles with GnRH antagonist protocol,on the basis of conventional luteal support,multi-dose intermittent short-acting GnRH-a for luteal support can achieve a good clin-ical outcome,and may be a suitable luteal support scheme for GnRH antagonist protocol in fresh embryo transfer cycles.
ABSTRACT
Androgen deprivation therapy (ADT) using gonadotropin?releasing hormone agonist (s) (GnRH?A) remains the backbone of advanced prostate cancer treatment. In this review, we assessed the efficacy, safety, and convenience of administration of various GnRH?A. All GnRH?A (goserelin, triptorelin, buserelin, histrelin, and leuprorelin) have comparable potential to suppress testosterone (T) levels (?50 ng/dL in a month and ?20 ng/dL in 3 months). However, goserelin has shown better efficacy in maintaining T levels ?50 ng/dL compared with leuprolide. The incidences of T escape are lower with goserelin and leuprolide than buserelin. Goserelin also has maximum benefit in prostate?specific antigen suppression. In neoadjuvant setting, when only goserelin was used, the 10?year overall survival (OS) rate was 42.6% to 86%. When either goserelin or leuprolide was used, the 10?year OS rate was 62%. As an adjuvant to radical prostatectomy, goserelin had a 10?year survival rate of 87%, and triptorelin had an 8?year survival rate of 84.6%. Goserelin further showed an absolute survival rate of 49% when used as an adjuvant to radiotherapy. The survival rates further improved when GnRH?A are used as combined androgen blockade compared with monotherapy. The frequency and severity of adverse events (hot flushes, fatigue, sexual dysfunction) are comparable among the GnRH?A. Goserelin appears to be the most convenient of all the GnRH?A for administration. Lack of conclusive comparative evidence makes it imperative to have a holistic approach of considering the patient profile and the disease characteristics to select the appropriate GnRH?A for ADT in prostate cancer.
ABSTRACT
ABSTRACT Objective: To investigate the effects of buserelin on the development of follicles, apoptosis index and steroid hormones level. Methods: Twenty-four 3-month-old female rats were randomly divided into three groups: a low-dose group, a high-dose group and a control group (n = 8). Buserelin and normal saline were injected subcutaneously for 5 days. Thirty days after the first injection, the ovaries were removed for staining. Blood samples were collected and centrifuged. Their serum was used for measuring estradiol and progesterone levels, using enzyme-linked immunosorbent assay. Results: The findings revealed a significant decrease in the mean of secondary and Graafian follicles in the high-dose group compared with the control group (p = 0.037, p = 0.034, respectively). The serum estradiol level increased significantly in the high-dose group, compared with the low-dose and control groups (p = 0.027, p = 0.047, respectively). The serum progesterone level decreased, although not significantly. In contrast to the control group, the significant increase of apoptotic cell death was found in primordial, unilaminar and multi-laminar follicles in the high-dose group (p = 0.004, p = 0.049, p = 0.047, respectively). Conclusion: The findings of this study suggest that short-term administration of high-dose buserelin increases the serum estradiol level and apoptosis in the granulosa cells but has an inhibitory effect on follicular development.
ABSTRACT
@#【Objective】To investigate the effect of adding different preparations containing luteinizing hormone activity in patients with normal ovarian reserve but suboptimal response during GnRH agonist protocol when undergoing IVF/ICSI- ET.【Methods】872 infertile patients with normal ovarian reserve but suboptimal response to FSH during GnRH agonist protocol were enrolled. According to the supplementation of different preparations containing LH activity ，patients were divided into three groups，including low- dose hCG group（n=28），rLH group（n=319）and HMG group（n=525）. The clinical parameters and pregnancy outcomes were retrospectively compared among three groups.【Results】The proportion of ultra-long GnRH-a protocol in hCG group was higher than that in HMG group（14.3% vs. 1.1%，P＜0.001）. The total duration and dosage gonadotrophin in hCG group were more than that in HMG group ［15.0（13.0~16.8）vs. 13.0（12.0~15.0）days ，P = 0.027 ；2 925（2 531~3 900）vs. 2 550（2 100~3 225）U ，P = 0.046］. The total duration and dosage gonadotrophin in rLH group were less than that in HMG group［13.0（12.0~14.0）vs. 13.0（12.0~15.0）days，P = 0.009；2 400（1 950~3 075）vs. 2 550（2 100~3 225）U ，P = 0.009］. There were 53.6%（15/28）patients who still showed suboptimal response after the administration of HMG or rLH in hCG group. The clinical pregnancy rate（69.2%，58.6% vs.63.8%；P＞0.05）and live birth rate（65.4%，49.6% vs. 53.1%；P＞0.05）were similar among these groups.【Conclusions】 For patients with normal ovarian reserve but suboptimal response during GnRH agonist protocol ，the supplementation of different preparations containing LH activity showed comparable effect on pregnancy outcomes. The addition of low- dose hCG was effective even when patients still showed suboptimal response after the administration of HMG or rLH.
ABSTRACT
Background: Circulating levels of luteinizing hormone (LH), follicle stimulating hormone (FSH) and progesterone (P4) in serum after administration of gonadotropin releasing hormone agonist (GnRHa) trigger for final oocyte maturation are found to be predictive of oocyte maturity. This prospective study was conducted at a tertiary care centre to evaluate relationship between serum LH, FSH and P4 levels at 12-h post-trigger and oocyte maturity rate and to predict which hormone has maximum sensitivity and specificity for appropriate oocyte maturation.Methods: Women at risk of ovarian hyper-stimulation syndrome who underwent either autologous or donor IVF cycle treated with flexible GnRH antagonist protocol were taken as participants of the study. GnRHa as trigger for final oocyte maturation was given. After 12 hours of agonist trigger, blood sample was drawn to assess LH, FSH and P4 levels in serum. Continuous variables were expressed as mean±SD. Independent sample t test was used for continuous variables which were normally distributed and Mann-Whitney U test for data not normally distributed. Main outcome measures were number of oocytes retrieved, oocyte maturity rate, fertilization rate, cleavage rate and grade of embryos.Results: There was a statistically significant reduction in number of retrieved oocytes, maturity rate, fertilization rate and grade 1 embryos with a concentration of serum LH and P4 less than the cut off value (p < 0.05).Conclusions: Serum LH and P4 level less than the cut off value at 12-hour post-trigger with GnRHa is associated with a dramatically less oocyte maturity rate and fertilization rate.
ABSTRACT
Objective To explore the significance of the cut point of peak level of luteinizing hormone (LH) in gonadotropin-releasing hormone (GnRH) agonist test in the diagnosis of precocious puberty in obese girls.Methods According to the diagnostic criteria of children's central precocious puberty diagnosis consensus (2015),796 cases of precocious puberty (peak level of LH ≥3.3 IU/L) in Children's Hospital of Zhejiang University School of Medicine from January 2014 to December 2015 were divided into normal weight group (573 cases),overweight group (170 cases) and obesity group (53 cases).The 3 groups were compared in terms of basic level of LH,basic level of follicle stimulating hormone (FSH),peak level of LH and FSH,ratio of LH (peak)/FSH (peak),sex hormone binding protein (SHBG),and children with 3.3 IU/L ≤peak level of LH ＜5.0 IU/L were followed up.The accuracy of the diagnosis of central precocious puberty using peak level of LH was analyzed by using receiver operating characteristic (ROC) curve.Results The median of LH (peak) in the obese group was 6.92 IU/L,the median of SHBG was 46.52 nmol/L,the median of LH (peak) in normal weight group was 8.92 IU/L,and the median of SHBG was 87.28 nmol/L.There were significant differences between the 2 groups (P ＜ 0.05,0.001).A total of 89 cases in normal weight group and 65 cases of obesity/overweight group (3.3 IU/L ≤peak level of LH ＜5.0 IU/L) were followed up for 1 year,and 18 cases in normal weight group and 33 cases in obesity/overweight group developed to central precocious puberty,while the number of cases in the 2 groups was significantly different (P ＜0.001).The ROC curve analysis showed that the cut point of peak level of LH was 4.16 IU/L,the sensitivity was 0.606,the specificity was 0.656,and the Jordan index was the largest (0.344).Conclusions The peak level of LH in GnRH agonist test is important for the diagnosis of central precocious puberty in girls,but the effect of body mass index on its cut point needs to be considered.
ABSTRACT
Objective To evaluate systematically the effectiveness of gonadotropin-releasing hormone agonist (GnRHa) administration before chemotherapy and/or during chemotherapy for the protection of ovarian function in premenopausal women. Methods PubMed, Cochrane Library, Medline, Embase, China Biomedical Literature Database, CNKI were searched to collect the clinical randomized control trail (RCT) of ovarian function protection in premenopausal women receiving chemotherapy by using GnRHa. RevMan5.3 software was used to analyze the incidence of early premature ovarian insufficiency (POI), menstrual recovery rate, pregnancy rate and other indicators. Results A total of 12 articles were included, including a total of 1509 premenopausal women who received chemotherapy for malignant diseases. GnRHa combined with chemotherapy reduced the incidence of POI (OR = 0.36, 95％ CI 0.23-0.56, P < 0.01) and improved the menstrual recovery rate during follow-up (OR = 2.49, 95％ CI 1.72-3.60, P < 0.01). GnRHa combined with chemotherapy could increase the pregnancy rate of patients aged 35 years and older (OR = 2.04, 95％ CI 1.08-3.83, P = 0.03). Conclusion GnRHa administration before chemotherapy and/or during chemotherapy may prevent the chemotherapy damage to ovarian function, reduce the incidence of POI, and improve the recovery rate of menstruation.
ABSTRACT
Objective:To explore the factors affecting the pregnancy outcome of frozen-thawed embryo transfer (FET) in endometriosis (EMT) patients in order to provide reference for the clinical selection of FET strategies. Methods:A total of 329 EMT patients who received blastocyst FET at the Reproductive Medicine Center, Department of Obstetrics & Gynecology, The 900th Hospital of the Joint Logistics Support Force, PLA, from Jan. 2015 to Dec. 2017 were analyzed retrospectively. The patients were divided into three groups according to endometrial preparation protocols, ages, and endometrial thickness on the day of progesterone conversion, respectively. By endometrial preparation protocols, the three groups included gonadotropin-releasing hormone agonist (GnRH-a) down-regulation+ hormone replacement therapy (HRT) group (GnRH-a+HRT group, A1 group, n=138), HRT group (B1 group, n=52), and natural cycle (NC) group (C1 group, n=139). By ages, the three groups included 35 years old group (C2 group, n=59). By endometrial thickness on the day of progesterone conversion, the three groups included 12 mm group (C3 group, n=37). The differences in pregnancy outcomes among EMT patients with blastocyst FET were compared under different grouping factors. Results:The endometrium of A1 group was significantly thicker than that of B1 group (P=0.041), the implantation rate and clinical pregnancy rate of B1 group were significantly higher than those of C1 group (P=0.000, P=0.003). Compared with A1 group, the implantation rate of B1 group was significantly higher (P=0.023), while it was significantly lower in group C1 (P=0.027). The abortion rate of A2 group was significantly higher than that of B2 group (P=0.007). Compared with A3 group, the implantation rate of B3 group was significantly higher (P=0.041), while it was significantly lower in C3 group (P=0.026). Conclusion:HRT endometrial preparation protocol for EMT patients with blastocyst FET can improve the implantation rate and clinical pregnancy rate, and reduce the abortion rate and ectopic pregnancy rate, which may be an economical and efficient endometrial preparation protocol in clinical.
ABSTRACT
OBJECTIVE: To evaluate the effect of Kuntai capsule on the gonadotrophin releasing hormone agonist(GnRH-a)-induced perimenopaus symptoms and the sex hormone levels.METHODS: A total of 99 patients with uterine fibroids,adenomyosis or moderate to severe endometriosis who needed the treatment of GnRH-a at Sun Yat-sen Memorial Hospital of Sun Yat-sen University from June 2015 to March 2016 were collected and randomly divided into research group(Kuntai capsule)and control group(Tibolone). GnRH-a was injected once every 28 days and first injection of GnRH-a was administered on the 2 nd to 4 th day of menstrual period or retraction bleeding after surgery.Kuntai capsule or Tibolone was orally taken beginning from the first GnRH-a injection,and the co-administration of Caltrate D-600 and alfacalcidol was given in both groups.The Kupperman scores,sex hormone levels including folliclestimulating hormone(FSH)and estrogen(E_2),and adverse events were recorded.RESULTS: Kuntai capsule kept the perimenopause symptoms at mild level with the slow increase of Kupperman scores,whose effect was significantly superior to Tibolone(P<0.05)after 8 weeks of treatment,especially in paresthesia,nervousness,and formication.The FSH and E_2 levels in both Kuntai and Tibolone groups were obviously decreased when compared with the pre-treatment(P<0.05),and these hormone levels in Kuntai group were comparable to those in Tibolone group.No adverse events occurred in either group. CONCLUSION: In the short-term treatment of GnRH-a,Kuntai capsule exhibits significant alleviating effects on perimenopause symptoms caused by GnRH-a with high safety and few adverse reactions.
ABSTRACT
Objective: To investigate the effects of three kinds of endometrial preparation (normal hormone replacement, half- and full-dose of long-acting gonadotropin-releasing hormone agonist (GnRH-a) down-regulation combined with hormone replacement) on the pregnancy outcomes in the frozen-thawed embryo transfer (FET) cycle in the patients with endometriosis (E M T), adenomyosis or repeated implantation failure (RIF) for unknown reasons, and to provide a basis for the selection of clinical endometrial preparation method. Methods: A total of 191 patients with EMT, adenomyosis or RIF for unknown reasons underwent FET treatment were selected. The patients were divided into normal hormone replacement group (n=63), half-dose GnRH-a group (n=61) and full-dose GnRH-a group (n=67) according to the endometrial preparation method. The clinical data of patients in each group such as age, body mass index (BMI), duration of infertility, the number of embryo transfer cycles, the number of embryos transferred, the endometrial thickness on the day of conversion and transplantation, the rate of high-quality embryos transferred, the intrauterine clinical pregnancy rate and the embryo implantation rate were analyzed retrospectively and compared. Results: There were no significant differences of the general clinical data of the patients in FET cycles in three groups such as age, BMI, duration of infertility, the number of embryo transfer cycles, the number of embryos transferred, the endometrial thickness on the day of conversion and transplantation, and the rate of high-quality embryos transferred (P
ABSTRACT
OBJECTIVE: To describe the clinical outcomes of frozen-thawed embryo transfer (FET) with artificial preparation of the endometrium, using a combination of estrogen (E2) and progesterone (P4) with or without a gonadotropin-releasing hormone agonist (GnRHa), and the modified natural cycle (MNC) with human chorionic gonadotropin (hCG) trigger. METHODS: In this retrospective study, we evaluated 187 patients during 3 years (February 2012–April 2015). The patients were allocated to the following treatment groups: group A, comprising 113 patients (181 cycles) who received GnRHa+E2+P4; group B, comprising 49 patients (88 cycles) who received E2+P4; and group C, comprising 25 patients (42 cycles) who received hCG+P4. The inclusion criteria were regular menstrual cycles (length 24–35 days) and age 21–45 years. RESULTS: The primary outcome of the study — implantation rate (IR) per embryo transferred — was not statistically different among the 3 groups. Similar results were found for the IRs with fetal heartbeat per embryo transferred (68/181 [37.6%] in group A vs. 22/88 [25.0%] in group B vs. 14/42 [33.3%] in group C) and for the live birth rates (LBRs) per embryo transferred (56/181 [30.9%] in group A vs. 18/88 [20.5%] in group B vs. 11/42 [26.2%] in group C). CONCLUSION: Although the pregnancy outcomes were better in the hormone therapy with GnRHa group, hormone therapy FET with GnRHa for pituitary suppression did not result in significantly improved IRs and LBRs when compared with hormone therapy FET without GnRHa or MNC FET.

ABSTRACT
[Objective] To investigate the effects of different doses of gonadotropin releasing hormone agonist (GnRH-α) on the down-regulation of normal ovarian reserve,and compared the down-regulation level as well as the clinical outcome of in vitro fertilization and embryo transfer (IVF-ET) cycles.[Methods] This RCT study included 63 infertility couples of age＜35 yrs.women with normal ovarian reserve function who were intended to received GnRH-α long protocol treatment.Of the 63 women were randomly divided into three groups according to the dose of triptorelin,21 received daily 0.05 mg short-acting GnRH-α,21 received daily 0.1 mg short-acting GnRH-α,while 21 received reduced-dose depot of 1.25 mg GnRH-αt.[Results] In the three groups,the average duration of down-regulation reached after injection of GnRH-α,the level of LH and E2,the total number of antral follicles,the number of antral follicles of ＜4 mm and 8～9 mm were similar.The serum follicle-stimulating hormone level on the day of gonadotropin initiation were significantly higher in the two short-acting groups compared with the long-acting group [(3.92 ± 1.12) U vs.(3.03 ± 1.14) U vs.(2.05 ± 1.12) U,P＜ 0.001].Four hours after the GnRHa injection,the serum FSH,LH levels were higher in short-acting 0.05 mg group than the short-acting short-acting 0.1 mg group.Both number of days of gonadotropin stimulation and gonadotropin doses were similar in three groups.On the day of hCG administration,the numbers of 14-18mm diameter follicles [(3.91 ±2.12) vs.(5.81 ±3.55) vs.(6.43±3.39),P＜0.001] as well as the proportion of follicles with diameter ≥18 mm/≥10 mm [(33.1％± 13.2％) vs.(24.0％±12.4％) vs.(30.1％±12.2％),P＜0.05],were both statistically significant different in three groups.Although serum LH level on hCG day was significantly increased in 0.05 mg group [(2.47±1.33) U vs.(1.80±0.69) U vs.(1.43±0.53) U,P＜0.05].No premature LH surge and premature ovulation was observed.The number of retrieved oocyteswas significant different [(10.14±4.80) vs.(11.51±2.42) vs.(12.79±2.73),P＜0.05].However,no significant differences was found regard to the number of MII oocytes,and the serum estrogen level per egg was significant higher in 0.05 mg group [(282.33±42.13) U vs.(221.62±32.02) U vs.(200.03±37.89) U,P＜0.001].The live birth rate (LBR) of these three groups in fresh cycles were 61.9％,55.0％,and 50.0％,respectively.The cumulative LBR were 85.7％,76.2％,and 75.0％,respectively.A increased trend was observed in the clinical pregnancy rate,cumulative clinical pregnancy rate and cumulative LBR in 0.05 mg group than the other two groups.[Conclusion] For women with normal ovarian reserve,as the GnRH-α dosage decreased,the down-regulation of pituitary reduced,while serum LH levels on the day of hCG trigger increased.The number of oocytes retrieved was decreased,the proportion of cycles which retrieved ＞ 15 oocytes was also lower.However,the average estrogen level per egg was significant increased,and a better clinical outcome of IVF-ET was received.
ABSTRACT
The clinical outcomes of five groups of infertility patients receiving frozenthawed,cleavage-stage embryo transfers with exogenous hormone protocols with or without a depot gonadotropin-releasing hormone (GnRH) agonist were assessed.A retrospective cohort analysis was performed on 1003 cycles undergoing frozen-thawed,cleavage-stage embryo transfers from January 1,2012 to June 31,2015 in the Reproductive Medicine Center of Wuhan General Hospital of Guangzhou Military Region.Based on the infertility etiologies of the patients,the 1003 cycles were divided into five groups:tubal infertility,polycystic ovary syndrome (PCOS),endometriosis,male infertility,and unexplained infertility.The main outcome was the live birth rate.Two groups were set up based on the intervention:group A was given a GnRH agonist with exogenous estrogen and progesterone,and group B (control group) was given exogenous estrogen and progesterone only.The results showed that the baseline serum hormone levels and basic characteristics of the patients were not significantly different between groups A and B.The live birth rates in groups A and B were 41.67％ and 29.29％,respectively (P＜0.05).The live birth rates in patients with PCOS in groups A and B were 56.25％ and 30.61％,respectively (P＜0.05).The clinical pregnancy,implantation and on-going pregnancy rates showed the same trends as the live birth rates between groups A and B.The ectopic pregnancy rate was significantly lower in group A than in group B.We concluded that the live birth rate was higher and other clinical outcomes were more satisfactory with GnRH agonist cotreatment than without GnRH agonist co-treatment for frozen-thawed embryo transfer.The GnRH agonist combined with exogenous estrogen and progesterone worked for all types of infertility tested,especially for women with PCOS.

ABSTRACT
Few studies have investigated the long-term effects of gonadotropin-releasing hormone (GnRH) agonist treatment on the reproductive function of central precocious puberty (CPP) girls. In this cross-sectional study, we assessed the ovarian function by analyzing the serum anti-Müllerian hormone (AMH) levels of CPP girls. Our study included 505 CPP girls subdivided into 5 groups according to the GnRH agonist treatment stage: group A (before treatment, n = 98), group B (3 months after initiation, n = 103), group C (12 months after initiation, n = 101), group D (24 months after initiation, n = 101), and group E (6 months after discontinuation, n = 102). We compared the serum AMH levels of the CPP girls with those of 100 bone age-matched controls (before treatment: n = 55; after discontinuation: n = 45). At baseline, the mean AMH level of the CPP girls was 5.9 ± 3.6 ng/mL. The mean AMH level after 3 months of the GnRH agonist treatment was lower (4.7 ± 3.2 ng/mL, P = 0.047) than that at baseline and recovered after 12 months of treatment. Six months after discontinuation, the AMH levels were similar to those at pre-treatment. Before and after the GnRH agonist treatment, the AMH levels were similar to those of the bone age-matched controls. In the precocious puberty girls, the AMH levels based on the GnRH agonist treatment stage were all within the normal reference range. The results of this study suggest that GnRH agonist treatment has no adverse effects on the reproductive function.

OBJECTIVE: The aim of this study was to evaluate the effect of short-term use of selective progesterone receptor modulator (SPRM) or gonadotropin-releasing hormone (GnRH) agonist on uterine fibroid shrinkage among Korean women. METHODS: This retrospective study involved 101 women with symptomatic uterine fibroids who received ulipristal acetate (SPRM, n=51) and leuprolide acetate (GnRH agonist, n=50) for 3 months between November 2013 and February 2015. The fibroid volume was measured both before and after treatment using ultrasonography, computed tomography, and magnetic resonance imaging. The outcomes were compared between the SPRM and GnRH agonist groups. RESULTS: The median rate of fibroid volume reduction after SPRM treatment was 12.4% (IQR −14.5% to 40.5%) which was significantly lower than the reduction rate observed after GnRH agonist treatment (median 34.9%, IQR 14.7% to 48.6%, P=0.004). 19 of 51 (37.3%) patients with SPRM treatment did not show any response of volume shrinkage, while 7 of 50 (14.0%) women with GnRH agonist showed no response (P=0.007). CONCLUSION: Short-term SPRM treatment yields lower volume reduction than GnRH agonist treatment in Korean women with symptomatic fibroids. Further large-scale randomized trials are needed to confirm our findings.

[Objective]To observe the dynamic changes of serum LH levels in different GnRH-along protocols ,and investigate the relationship between GnRH-adosage and LH levels ,and compare the clinical outcomes among different GnRH-a long protocols.[Methods]In this retrospective study,1.0 mg,0.8 mg,0.375 mg long-acting and 0.1 mg/d,0.05 mg/d short-acting GnRH-a long protocols were included from January to June in 2015 at the Reproductive Medicine Center of the First Affiliated Hospital of Sun Yat-Sen University. Serum LH levels were evaluated from a total of 250 women at the four time points,on the day before gonadotropin stimulation(Gn0),the fourth day of Gn stimulation(Gn4),the seventh day of Gn stimulation(Gn7),and the HCG administration day(HCG day),then the relationship between serum LH levels and the dosage of GnRH-a were analyzed. The number of oocytes retrieved,fertilization rate,good quality embryos rate,blastocyst transferred rate,the number of transferred embryos,implantation rate and clinical pregnancy rate were also compared.[Results]Among the long-acting groups,LH levels in 0.375 mg group were higher than those in 1.0 mg and 0.8 mg groups at the four time points(P0.05). In short-acting groups,the LH levels in 0.05 mg/d protocol were significantly lower than those in the 0.1 mg/d group at Gn0,Gn7 and HCG day(P0.05).[Conclusion]Among the long-acting groups,the smaller amount of GnRH-a was administrated ,the higher LH levels during ovarian stimulation and implantation rate the patients ob?tained. As to the short-acting groups,the LH level and implantation rate in 0.1 mg/d group is higher than those in 0.05 mg/d group.
ABSTRACT
[Objective]To compare the clinical outcomes of fresh embryo transfer of the in vitro fertilization/intracytoplasmic sperm injection and embryo transfer(IVF/ICSI-ET)in different age groups as well as in different responders using gonadotropin-re-leasing hormone agonist(GnRH-a)long protocol or GnRH antagonist(GnRH-ant)protocol.[Methods]A retrospective analysis was performed on 737 IVF/ICSI cycles,including 386 cycles of GnRH-a long protocol(group A)and 351 cycles of GnRH-ant protocol (group B),from August 28,2015 to December 31,2016. Then all the cycles were divided into sub-groups by ages and retrieved oo-cyte numbers:group a1(15). The basic information of patients and clinical outcomes were compared.[Results](1)Comparable results were obtained from group A and group B in these following variables such as fertilization rate,normal fertilization rate,biochemical pregnancy rate and miscarriage rage. But the stimulation period,the total gonadotropin(Gn)dosage,estradiol(E2)level and endometrial thickness on the day of human chorionic gonadotropin(hCG)administration,number of oocytes retrieved and mature oocytes,ovarian hyperstimulation syn-drome(OHSS)rate,implantation rate and clinical pregnancy rate were significantly higher in group A than group B(P<0.05),and significantly higher cancellation rate of fresh embryo transfer was observed in group B(P<0.001).(2)When divided by ages,no mat-ter in sub-group a1 or sub-group a2,the implantation rate was slightly lower in GnRH-ant protocol than in GnRH-a long protocol, although they failed to reach significant difference(sub-group a1:32.6%vs 39.8%,P=0.067;sub-group a2:9.7%vs 17.9%,P=0.066). The clinical pregnancy rate was comparable using these two protocols in sub-group a1(54.8%vs 50.4%,P=0.429),but it was significantly lower by using GnRH-ant protocol than GnRH-a long protocol in sub-group a2(19.6%vs 39.1%,P=0.021).(3) When divided by numbers of oocytes retrieved,the implantation rate was significantly lower when using GnRH-ant protocol in sub-group b1(13.1%vs 26.0%,P=0.026),but we failed to observe significant differences in other two sub-groups. The clinical preg-nancy rates were comparable in all sub-groups ,whereas differed considerably in sub-group b1 (36.6% vs 19.3%,P = 0.056).[Conclusion]Overall,the implantation rate and clinical pregnancy rate were higher in GnRH-a long protocol than those in GnRH-ant protocol. Nevertheless,GnRH-ant protocol could reduce the dosage of Gn,shorten the treatment duration,and effectively reduce the occurrence of OHSS. There were similar pregnancy outcomes in two protocols for normal responders and high responders ,while for advanced patients or other poor responders,the implantation rate and clinical pregnancy rate were higher in GnRH-a protocol.
ABSTRACT
Objective To evaluate the curative effect of laparoscopic myomectomy combined with preoperative gonadotropin releasing hormone agonists (GnRH-a) in treating myoma patients with uterus volume large than 12 weeks of pregnancy size. Methods 46 patients with uterine volume over 12 gestational weeks from August 2009 to August 2016 were selected as research objects. Leuprolide was injected subcutaneously for three to six times, and then laparoscopic myomectomy was performed one month later. The changes of volumes in uterus and myoma before and after medication were observed as well as the changes of hemoglobin. And postoperative recurrence of uterus myoma was followed up. Results The average volume of the uterus in the 46 patients, detected by B ultrasound, before GnRH-a treatment was (705.47 ± 282.37) cm3, and the average volume of the uterus after GnRH-a treatment was (331.95 ± 84.53) cm3, which was shortened by 59.35%, with significant difference (P < 0.05). The volume of uterus myoma was (237.59 ± 138.46) cm3 before GnRH-a treatment and (81.59 ± 46.44) cm3 after GnRH-a treatment, shortened by 65.66%, with significant difference (P < 0.05). The hemoglobin value was (97.80 ± 20.19) g/L before GnRH-a and (119.63 ± 12.06) g/L after GnRH-a treatment, with significant difference (P < 0.05). Follow-up for 3 weeks to 5 years, the surgeries were accomplished successfully, and no case was transferred to laparotomy. Conclusion Preoperative GnRH-a could shorten volume of uterus myoma, increase hemoglobin value and ensure performance of laparoscopic myomectomy for myoma patients with uterus volume large than 12 weeks of pregnancy size.
