Summary
Oocytes and matched samples of follicular fluid were obtained from 52 preovulatory follicles aspirated laparoscopically for in vitro fertilization (IVF). Follicular fluid concentrations of estradiol (E2), progesterone (P), testosterone (T), prolactin (HPRL), prostaglandin F2α (PGF2α), prostaglandin E (PGE), protein content, and collagenolytic activity were measured and related to the fertilization rate of oocytes cultured in vitro. High concentrations of P and low levels of T and HPRL were associated with mature, fertilizable oocytes. Levels of PGF2α, PGE, and follicular fluid protein concentrations were similar in both groups. Mean collagenolytic activity was increased in the fertilized oocytes, although no significant difference could be observed. Our data demonstrate a close association between follicular fluid steroid and HPRL concentrations and successful fertilization of oocytes.
