ABSTRACT
OBJECTIVE:
To compare the efficacy and safety of urinary FSH and recombinant FSH for ovulation induction in patients with clomiphene citrate-resistant, normogonadotropic, chronic anovulation.DESIGN:
Prospective, randomized trial.SETTING:
University-based infertility clinic. PATIENT(S) Fifty-one women. INTERVENTION(S) Subjects were randomized to receive either urinary FSH (35 patients, 64 cycles) or recombinant FSH (16 patients, 32 cycles). A maximum of three cycles using the low-dose step-up protocol with the same gonadotropin were undertaken. MAIN OUTCOME MEASURE(S) Cumulative ovulation and pregnancy rates after three cycles, total gonadotropin dose, duration of stimulation, and single follicle development rate. RESULT(S) Cumulative ovulation rates were 89.3% and 93.1% for the urinary FSH and recombinant FSH groups, respectively. The threshold and total doses of FSH and the duration of stimulation were similar between the two groups. Significantly more single follicle development was noted in the recombinant FSH group. The respective clinical pregnancy rates per noncanceled cycles in the urinary FSH and recombinant FSH groups were 23.2% and 27.6%. There were three sets of twins in the urinary FSH group. No case of ovarian hyperstimulation syndrome was encountered. CONCLUSION(S) Urinary FSH and recombinant FSH are both efficient and safe for inducing ovulation with the low-dose step-up protocol.
