OBJECTIVE: The aim of the present randomized study was to investigate whether ovarian stimulation treatment with gonadotropin preparations containing different amounts of LH activity resulted in variations of steroidal composition of follicular fluid. A different endocrine milieu within the follicle might influence oocyte quality.
METHODS: Antral fluid from mature follicles was collected in in vitro fertilization cycles and concentrations of testosterone, androstenedione, estrone, estradiol, progesterone, FSH, and LH were determined. A comparison was made between treatment with a purified FSH preparation (nine patients, 35 follicular fluid samples) and a FSH-dominant human menopausal gonadotropin (hMG) preparation (nine patients, 34 samples).
RESULTS: No differences in any of the hormone levels could be detected between the two groups.
CONCLUSION: Treatment with gonadotropin preparations containing different FSH/LH ratios did not result in different androgen, estrogen and progesterone levels in follicular fluid.
