Abstract
OBJECTIVE
To compare the efficacy and safety of three different ratios of human-derived follicle-stimulating hormone/human menopausal gonadotropin (human-derived FSH:hMG, Bravelle and Repronex) mixed together in the same syringe and administered subcutaneously once daily, to in vitro fertilization (IVF) patients <34 years or 34 to 40 years of age.
DESIGN
Two randomized, prospective, age stratified, IVF studies.
SETTING
Twenty-one academic and private clinics with experience in IVF/embryo transfer (ET).
PATIENT(S)
Infertile premenopausal women undergoing IVF-ET.
INTERVENTION(S)
Pituitary suppression with leuprolide acetate, randomization to one of three treatment groups, followed by gonadotropin stimulation (GS) for up to 15 days. The human-derived FSH:hMG ratios were the following: Group 1, a 1:1 ratio throughout; Group 2, a 3:0 ratio that was changed to 1:1 after GS day 5; Group 3, a 2:1 ratio that was increased to 3:1, 4:1, or 5:1 after GS day 5, as needed.
MAIN OUTCOME MEASURE(S)
Mean number of oocytes retrieved; peak estradiol levels; dose and duration of stimulation; implantation rates; adverse events; injection site pain; and pregnancy and live birth rates.
RESULT(S)
Overall, women <34 years had higher E(2) levels, more oocytes retrieved, and improved implantation and live birth rates compared with women 34 to 40 years old. Nonetheless, each ratio of human-derived FSH:hMG produced comparable implantation rates, and continuing pregnancy and take-home baby rates.
CONCLUSION(S)
All three ratios of human-derived FSH:hMG in both age groups produced comparable pregnancy and live birth rates with similar safety results.
