Aim: The aim of this study was to evaluate the effect of oral N‐acetylcysteine (NAC) administration as an adjuvant to clomiphene citrate (CC) on induction of ovulation outcomes in patients with polycystic ovary syndrome (PCOS). Material and Methods: In this placebo‐controlled double‐blind randomized clinical trial, 180 PCOS infertile patients were randomly divided into two groups for induction of ovulation. Patients in group 1 received CC 100 mg/d plus NAC 1.2 g/d and patients in group 2 received CC plus placebo for 5 days starting at day 3 of the cycle. On the 12th day of the menstrual cycle in the presence of at least one follicle with an 18–20‐mm diameter in ultrasound evaluation, 10 000 U hCG was injected intramuscularly and timed intercourse was advised 36 h after hCG injection. Serum β‐hCG level was measured on the 16th day after hCG injection. Results: The number of follicles >18 mm and the mean endometrial thickness on the day of hCG administration were significantly higher among the CC+NAC group ( P ‐value = 0.001). The ovulation and pregnancy rates were also significantly higher in the CC+NAC group ( P ‐value = 0.02 and 0.04, respectively). No adverse side‐effects and no cases of ovarian hyperstimulation syndrome were observed in the group receiving NAC. Conclusion: NAC as a safe and well‐tolerated adjuvant to CC for induction of ovulation can improve the ovulation and pregnancy rates in PCOS patients. It may also have some beneficial impacts on endometrial thickness.
