We performed a prospective study to assess the effects of a starting dose of 50 units of recombinant follicle stimulating hormone (Puregon) during gonadotrophin-releasing hormone agonist therapy (Suprecur) on follicular development in patients with clomiphene citrate-resistant polycystic ovary syndrome (PCOS). In a prospective clinical trial, 25 women with clomiphene citrate-resistant PCOS who wanted to become pregnant were treated by a low-dose step-up protocol of SC recombinant follicle stimulating hormone administration during gonadotrophin-releasing hormone agonist therapy, monitored by transvaginal ultrasonography and retrospectively by serum endocrine assays taken at each monitoring visit. Cancellation of cycles, ovulation, rate and size of follicles growth, serum E2 concentration and pregnancy were recorded. All patients exhibited a response: 22 patients ovulated, of whom 10 conceived. Using the low-dose protocol during gonadotrophin-releasing hormone agonist therapy permitted induction of ovulation safely and successfully in patients with clomiphene citrate-resistant PCOS who were patients previously difficult to treat with the conventional ovulation induction protocol.
