Lactate dehydrogenase estimation in follicular fluid: correlation with patient age, follicle size and super ovulation in ART cycles.

Objective: To quantify the lactate dehydrogenase (LDH) level in human follicular fluids, and to define its relationship with follicle size, patient age, serum estradiol (E(2)) level, and the amount of gonadotropins administered during superovulation in ART cycles.

Study Design: In this prospective study, 21 women undergoing ART treatment were selected. Follicular fluid from the largest follicle of both ovaries was collected from each patient on the day of oocyte aspiration and analyzed for LDH.
