Objective: To compare the efficacy of two doses (250 μg vs. 500 μg) of r-hCG for oocyte maturation in obese women with a body mass index (BMI) ≥30 and undergoing assisted reproduction techniques. Materıals and Methods: A Prospective, randomized, clinical study of seventy two patients undergoing IVF/ intracytoplasmic sperm injection cycles with BMI ≥30 kg/m2. Patients with high BMI were randomized to receive either 250 μg or 500 μg rhCG. Blood and follicular fluid (FF) samples were collected on the day of oocyte pick-up (OPU). The outcome measures were serum and FF hCG levels on the day of OPU, number of oocytes retrieved per patient, number of mature oocytes retrieved, clinical pregnancy rates (PR). Results: Serum hCG levels were significantly lower in patients receiving 250 μg of r-hCG than in patients receiving 500 μg of r-hCG. However FF hCG levels, implantation rates, abortion rates, clinical PRs were not significantly different. Conclusions: 250 μg of r-hCG is sufficient and safe to trigger ovulation in women with BMI ≥30.
