Abstract |
Twenty-four couples with unexplained infertility were studied in a spontaneous cycle followed by a clomiphene citrate (CC) cycle (150 mg, days 5-9). All spontaneous cycles were ovulatory, as defined by follicular collapse determined by transvaginal sonography. In CC cycles, 6/24 (25%) cycles demonstrated luteinized unruptured follicles ( LUF). In 2/6 LUF cycles there was no apparent luteinizing hormone (LH) surge. LUF cycles had significantly elevated LH levels in the follicular phase compared to ovulatory CC cycles. There was no apparent difference in serum oestradiol. In CC cycles multifollicular development occurred in 87.5% of cycles, with significantly elevated serum oestradiol. Luteinizing hormone and follicle-stimulating hormone were elevated in the follicular phase compared to spontaneous cycles. This study suggests a high incidence of LUF when CC is administered to ovulatory patients, and its use in patients with ovulatory infertility is questioned.
