Comparison of clomiphene citrate and letrozole for ovulation induction in women with polycystic ovary syndrome: a prospective randomized trial

To compare the therapeutic efficacy of clomiphene citrate (CC) and letrozole (LE) on ovulation, pregnancy, and live birth in women with polycystic ovary syndrome (PCOS); and to ensure if LE can replace CC as the first-line therapy for ovulation induction in these women. This is a prospectively, randomized, controlled trial in the tertiary hospital. Two-hundred and sixty-eight anovulatory PCOS patients were treated by CC or CC plus metformin and LE or LE plus metformin for three continuous cycles or conception; their ovulation rates, pregnancy rates, and live birth rates were calculated and compared. No significant difference was noted among the four groups regarding to the baseline data of clinical manifestations, serum sex hormone levels, and serum insulin levels. A total of 240 patients completed the therapies. The ovulation rate was significantly higher in the group LE than the group CC; however, no significant difference was noted between the groups LE and CC, CC, and CC?+?MET, or LE and LE?+?MET in the pregnancy rate, abortion rate, and live birth rate. No birth defect was found in the total of 63 newborns. CC regimen was still recommended to be the first-line therapy of ovulation induction for PCOS.     

Clomiphene citrate combined with metformin versus letrozole for induction of ovulation in clomiphene-resistant polycystic ovary syndrome: a randomized clinical trial

A total of 202 patients with clomiphene citrate (CC) -resistant polycystic ovary syndrome (PCOS) were randomly allocated into two arms of induction of ovulation; the first group (n?=?102) received CC 100?mg and metformin 500?mg while the second group (n?=?100) received letrozole 2.5?mg with ovulation rate, clinical pregnancy rate, adverse effects, and acceptability were assessed. Patients in the letrozole arm experienced higher rate of ovulation (82% versus 43.1%, p?p?p?p?p?p?p?相似文献   

Comparison of endometrial receptivity of clomiphene citrate versus letrozole in women with polycystic ovary syndrome: a randomized controlled study

Abstract

The aim of the study was to compare the effect of clomiphene citrate (CC) and letrozole on endometrial receptivity for ovulation induction in women with polycystic ovary syndrome (PCOS). A randomized controlled study included 160 patients diagnosed with PCOS, out of which 80 patients received 50?mg of CC and 80 patients received 2.5?mg of letrozole for successful ovulation induction. Endometrial thickness and pattern, the blood flow of uterine artery and subendometrial region, endometrial volume and vascularization index were measured. The ratio of multilayered endometrial pattern in letrozole group was significantly increased on the day of human chorionic gonadotropin (hCG) administration compared with CC group (77.5% vs. 55.0%). The volume, vascularization index (VI), flow index (FI), and vascularization flow index (VFI) of endometrium on the day of hCG administration and 7–9?days after ovulation in letrozole group were significantly increased. The biochemical pregnancy rate, clinical pregnancy rate, and ongoing pregnancy rate in letrozole group were significantly increased compared with CC group (36.3%, 30.0%, 22.5% vs. 21.3%, 13.8%, 10.0%, respectively). Letrozole increased pregnancy rates by improving endometrial receptivity compared with CC in patients with PCOS.     

Endometrial biopsy during induction of ovulation with clomiphene citrate in polycystic ovary syndrome

Background.?The dichotomy between ovulation rates and pregnancy rates for women with polycystic ovary syndrome (PCOS) treated with clomiphene citrate (CC) prompted the present study to determine the effect of CC on endometrial maturity.

Methods.?Retrospective case–control study of anovulatory women with PCOS (n = 119) on their third ovulatory cycle of CC and controls, 238 healthy regularly ovulating women whose partners had abnormal sperm, all of whom had an endometrial biopsy in the late luteal phase.

Results.?Endometrial histology classified according to the classical Noyes criteria revealed out-of-phase endometrium in 19/119 (16%) of the CC group compared with 7/238 (3%) in controls (p < 0.0001). Duration of the luteal phase was not influenced by histological age of the endometrium. Endometrial biopsy performed during 138 conception cycles extracted from the database did not increase the miscarriage rate significantly (23.9%).

Conclusions.?CC treatment significantly increases the prevalence of out-of-phase endometrium and this could explain, in part, the large difference between ovulation and pregnancy rates. There was no correlation between the results of the endometrial biopsy and the duration of the luteal phase. Performing an endometrial biopsy during a conception cycle does not seem to have a significant negative effect on the outcome of pregnancy.     

N-acetyl-cysteine is a novel adjuvant to clomiphene citrate in clomiphene citrate-resistant patients with polycystic ovary syndrome

OBJECTIVE: To evaluate the effect of N-acetyl-cysteine (NAC), a mucolytic drug with insulin sensitizing properties, as an adjuvant therapy in subjects with polycystic ovary syndrome (PCOS) resistant to clomiphene citrate (CC). DESIGN: Placebo-controlled, double-blind randomized trial. SETTING: University-based hospital and private infertility practice. PATIENT(S): One hundred fifty women diagnosed with CC-resistant PCOS, aged 18-39 years undergoing therapy for infertility were included. INTERVENTION(S): The patients were assigned randomly to receive either NAC 1.2 g/d (group I) or placebo (group II) with CC 100 mg/d for 5 days starting at day 3 of the cycle. MAIN OUTCOME MEASURE(S): Ovulation rate and pregnancy rate (PR). RESULT(S): Combination of CC and NAC significantly increased both ovulation rate and PR in women with CC-resistant PCOS (49.3% vs. 1.3% and 21.3% vs. 0%, respectively). No cases of ovarian hyperstimulation syndrome (OHSS) were reported in the NAC group; two cases of miscarriage (12.5%) were reported. CONCLUSION(S): The NAC as an adjuvant to CC was more effective than placebo for CC-resistant patients with PCOS. It is safe and well tolerated.
