Objective: To compare between luteal phase clomiphene citrate and second cycle day clomiphene citrate on the thickness of the endometrium and clinical pregnancy rates women with polycystic ovary syndrome.
Methods: a prospective observational study conducted on 198 women with Polycystic ovary syndrome divided into two groups: Group 1 (98 patients) received 100mg of clomiphene citrate daily for 5 days starting on second cycle day and Group 2 (98 patients) received 100mg of clomiphene citrate daily starting in the luteal phase before onset of withdrawal bleeding for 5 days. Treatment and follow up applied for three cycles. Outcome measures were collected and analyzed and women who got pregnant were followed until 12 weeks of pregnancy.
Results: no significant differences between the two groups regarding pre-ovulatory endometrial thickness (8.3mm in group 1vs 8.8mm in group 2), number of mature follicles (1.62 in group 1vs 1.57 in group 2) and mid-luteal serum progesterone levels(14.63ng/ml in group 1vs 14.9ng/ml in group 2). 34 women (35%) got pregnant in group 1 and 37 women (38%) in-group 2 and three patients had miscarriage in each group without any statistical significance.
Conclusion: the present study does not support luteal clomiphene citrate over second cycle day clomiphene citrate to induce ovulation in infertile women with polycystic ovary syndrome.
