Background: Clomiphene citrate (CC) is still the traditional therapy used for inducing ovulation in polycystic ovary syndrome (PCOS). Clomiphene resistance, which refers to persistence of anovulation after standard CC therapy, occurs in 15%–20% of patients. We aimed to compare between extended letrozole versus recombinant FSH in ovulation induction in cases of clomiphene resistant polycystic ovary Methods: Seventy women with PCOS were included then patients were equally randomized to receive one of the two drugs to be given over the next 3 months. In current study Group A: letrozole group 2.5 mg two tablets once daily for 10 days from day 2 of menses. Group B: Recombinant FSH 75 i.u s.c daily from day 2 for 5 days then monitoring dose according to folliculometry. Results: There was non-significant difference between two groups as regard FSH and LH but as regard Serum E2 (pg/mL) at day 5 of HCG administration there was significant higher in FSH recombinant group. There was insignificant difference between two groups as regard Ovulating, Number of follicles >18. There was insignificant difference between two groups as regard Size of dominant follicle, endometrial thickness at hCG (mm). OHSS, discontinuation due to OHSS, clinical pregnancy, multiple pregnancy and abortion was higher in FSH recombinant group but differences didn’t reach significance. Conclusions: There was non-significant difference between two groups in relation to ovulation, Number of follicles, Size of dominant follicle, Endometrial thickness at day of HCG injection however it was reported that OHSS, discontinuation due to OHSS, positive pregnancy test, was higher in FSH recombinant group but differences didn’t reach significance level.

Background: To compare two protocols comprising of FSH/CC/HMG and CC/HMG for ovulation induction and IUI in women with infertility.Methods: 60 women with unexplained infertility were randomized using sequentially numbered opaque envelope method. Group A received inj FSH 150 units on day 2 of menstrual cycle and clomiphene citrate 100 mg from day 3-7, followed by injection HMG 150 units on day 9 of menstrual cycle. Group B received clomiphene citrate 100 mg from day 3-7, and HMG 150 units on day 7 and 9 of the menstrual cycle.  Ovulation triggered with hCG 5000 units when dominant follicle was 18mm. Single IUI was done 36-42 hours afterwards.Results: Pregnancy occurred in 3 out of 30 women in 116 cycles Group A (with FSH) with a pregnancy rate of 10 percent, and 2.8% per cycle. In group B (without FSH) pregnancy occurred in 3 out of 30 women in 117 cycles with pregnancy rate of 10 percent, and 2.6% per cycle. The number of follicles per cycle was 1.36 and follicle size was 18.57 mm in group A. While in Group B numbers of follicles per cycle were 1.22, with average size of 18.9mm. Mean endometrial thickness was 7.7mm in Group A and 6.37 in Group B (p=.01, significant). Mild OHSS was observed in one woman in Group B. No other side effects were observed in both the groups.Conclusions: The controlled ovarian stimulation regimes used in this study are equally effective, easy to administer, require less intensive monitoring and fewer medications, with little risk of OHSS and multiple gestation.

Objective To compare the effects of letrozole (5 mg) and clomiphene citrate (100 mg) for ovulation induction in women with polycystic ovary syndrome (PCOS). Design Prospective randomized trial. Setting University teaching hospital and private practice setting. Patients The study comprised a total of 438 infertile women (1063 cycles) with PCOS. Intervention Patients were randomized to treatment with 5 mg of letrozole daily (218 patients, 545 cycles) or 100 mg of clomiphene citrate daily (220 patients, 518 cycles) for 5 days starting on day 3 of menses. Timed intercourse was advised 24 to 36 hours after hCG injection. Main Outcome Measure Number of follicles, serum estradiol, serum progesterone, endometrial thickness, and pregnancy and miscarriage rates. Results The mean age, parity, and duration of infertility in both groups were similar. The total number of follicles was statistically significantly greater in the clomiphene citrate group (6.8 _ 0.3 vs 4.4 _ 0.4). Endometrial thickness at the time of hCG administration was statistically significantly greater in the CC group (9.2 _ 0.7 mm vs 8.1 _ 0.2 mm). The duration to reach a dominant follicle was statistically significantly longer in the letrozole group (12.1_1.3 vs 8.8_2.9 days). Ovulation occurred in 365 out of 540 cycles (67.5%) in letrozole group and 371 out of 523 cycles (70.9%) without a statistically significant difference. Levels of serum estradiol and progesterone were statistically significantly higher in the clomiphene citrate group. The pregnancy rate per cycle was 15.1% in the letrozole group and 17.9% in the clomiphene citrate group without statistically difference between the groups. Conclusion The results of this study did not show any advantage to the use of letrozole over clomiphene citrate as a first-line treatment for induction of ovulation in women with PCOS (Fertil Steril_2009;92:849-52. _2009 by American Society for Reproductive Medicine).

Background: Polycystic ovarian disease (PCOD), a common endocrine disorder with multisystem affection, is the most common cause of anovulatory infertility. Our objective is to evaluate the effect of using clomiphene citrate (CC) plus N-acetyl cysteine (NAC) versus letrozole in ovulation induction in infertile patients with PCOD.Methods: Reproductive-aged infertile women either primary or secondary diagnosed as PCOD according to Rotterdam criteria, 2003 were considered for enrollment. Eligible women for were recruited and randomized (1:1) to receive either CC 100 mg plus NAC 600 mg (CC+NAC arm) or letrozole 5 mg (NCT03241472, clinicaltrials.gov). All medications were started from day 3 of the menstrual cycle for 5 days. The primary outcome was the ovulation rate in both groups. Secondary outcomes included the mid-cyclic endometrial thickness, ovarian hyperstimulation, and clinical pregnancy and miscarriage rates.Results: One hundred ten patients were enrolled and randomized to CC+NAC arm (n=55) or letrozole (n=55). The ovulation rate in patients in letrozole arm was significantly higher than CC+NAC arm (71.8% versus 53.2%, p=0.01). Additionally, endometrial thickness was higher in letrozole arm (mean±SD: 11.46±1.61 versus 9.0±1.13, p=0.031). However, no statistical significant difference with regarding the ovarian hyperstimulation rate (1.8% versus 3.6%, p=0.157), clinical pregnancy rate [3/19 patients (27.3%) versus 19/55 (34.5%), p=0.409] and miscarriage rate [4/15 patients (26.7%) versus 19/55 (15.8%), p=0.317] in CC+NAC versus letrozole groups respectively.Conclusions: Addition of NAC to CC in ovulation induction leads to comparable pregnancy rate as letrozole. However, letrozole produces high ovulation rate and the better mid-cyclic endometrial thickness.

Background: Polycystic ovary syndrome is the commonest endocrinopathy resulting in anovulatory infertile young women. Clomifene citrate (clomiphene) is a long-standing standard drug for ovulation induction, and is still considered as first line option in PCOS women. However, clomiphene has certain disadvantage letrozole an aromatase inhibitor acts by reducing estrogen production and has no adverse effects on endometrium and cervical mucous. Indian PCOS women have high prevalence of insulin resistance and thus are likely to have high clomiphene resistance. So letrozole could prove to be a good alternative for ovulation induction in such women.Methods: This was a prospective randomized, parallel, comparative clinical trial of two ovulation induction drugs letrozole 5 mg versus clomiphene citrate 100 mg as first-line ovulation induction drug in infertile polycystic ovarian syndrome women. The target population of the study was one hundred infertile women with PCO (taking at least 2 Rotterdam’s parameters). 50 women were allocated to clomifene citrate and 50 were allocated to Letrozole for ovulation induction. Parameters like age, duration of infertility, B MI, ovulation rate, number of follicles, pregnancy rate, endometrial thickness were noted and analyzed.Results: In letrozole group, the ovulation rate, mono-follicular development, mean endometrial thickness and pregnancy rate was better in comparison to clomifene citrate group.Conclusions: The result of this study suggests that letrozole may replace clomiphene as the first line drug for ovulation induction in infertile PCOS women.

Background: The objective of this study was to compare clomiphene citrate with letrozole for ovulation induction in anovulatory infertile women.Methods: This study was conducted in the infertility clinic and department of obstetrics and gynecology, S.P. Medical College and Associated P. B. M. Hospital, Bikaner, Rajasthan, from 1st August 2018 to 31st July 2019. The study group comprised of infertile females attending infertility clinic or gynae outdoor in department of obstetrics and gynecology, S. P. Medical College Bikaner for infertility. 100 women with anovulatory infertility were enrolled in the study after fulfilling the inclusion and exclusion criteria. Proper counseling was done and written informed consent taken.Results: Ovulation rate was statistically significantly greater in letrozole group. Monofollicular development was statistically significant greater in let group (CC 18%, Let 66%). The endometrial thickness on the day of ßhCG administration in CC group was 7.40±1.08 mm and in let group was 8.20±0.82 mm. Letrozole treated cases had better trilaminar pattern of endometrium as compared to clomiphene. The pregnancy rate was higher in letrozole group.Conclusions: As compare to clomiphene, letrozole is associated with higher pregnancy rate and ovulation rates among infertile women with anovulation.

Background: Anovulatory dysfunction is a commonly encountered problem which is responsible for about 40% of female infertility. One of the leading causes of female infertility is polycystic ovarian syndrome (PCOS). Clomiphene citrate has been the drug of choice in treating women with anovulatory infertility. However, in recent years, letrozole, an aromatase inhibitor, has emerged as alternative ovulation induction agent. Aim of this study was to compare efficacy of clomiphene citrate and letrozole as first line therapy for ovulation induction in polycystic ovarian syndrome.Methods: This study was a hospital based prospective comparative study done in MVJ MC and RH involving 100 females suffering from infertility due to anovulation. They were divided into 2 groups of 50 each. One group was given clomiphene citrate 50 mg while another group was given letrozole 2.5 mg from day 3 to day 7 of menstrual cycle. Ultrasonographic follicular monitoring was done and injection beta HCG 5000 IU was given once follicle reached optimum size (≥18 mm) and endometrial thickness was adequate (≥7 mm). Patients were advised for timed intercourse after 24-36 hours of HCG administration. Ovulation was detected by sonographic findings of follicular rupture done after 48 hours. Primary outcomes measured were number of growing follicles (≥18 mm), endometrial thickness, ovulation rate and pregnancy rate.Results: In our study there was significant difference in the outcomes of ovulation induction between letrozole group and clomiphene group.  Women who received letrozole showed improved endometrial growth (8.44 mm versus 7.86 mm), ovulation rate (72% versus 56%) and pregnancy rate (22.2% versus 14.3%) than those who received clomiphene. However, variation in follicular growth was negligible between the two groups (1.28 versus 1.36).Conclusions: Letrozole is a superior alternative to clomiphene citrate for ovulation induction in cases of PCOS with anovulatory menstrual cycle, and can be considered as first-line therapy for ovulation induction in such women.
