Correlation between follicular fluid content and the results of in vitro fertilization and embryo transfer. I. Sex steroids.
The steroid content of 72 follicular fluids (FF) obtained from 42 women subjected to ovulation induction with the luteinizing hormone-releasing hormone analogue D-Trp6 and human menopausal gonadotropin was studied in terms of the evolution of in vitro fertilization (IVF) and embryo transfer (ET) results. The FF were classified into several categories based on oocyte evolution. Individual values of FF estrone and estradiol (E2), as well as androstenedione and testosterone could not be correlated with ET outcome. However, FF progesterone (P) levels for follicles leading to pregnancy were significantly lower when compared with those in the other categories. The correlation between the E2/P ratio and E2 permitted the definition of a band wherein IVF-ET outcome was successful and enabled the characterization of different functional follicular maturational states.
