Interleukin-6 biosynthesis in human preovulatory follicles: some of its potential roles at ovulation.

In the present work we explored cellular sites of interleukin-6 (IL-6) biosynthesis in human follicular aspirates from patients undergoing in vitro fertilization therapy and the effects of this cytokine on oocyte fertilization and granulosa cell (GC) steroidogenesis. Biological IL-6 activity from 20-40 IU/mL was present in follicular fluids from 22 patients; it was also detected in 10 of 22 sup...

Temporal changes in inhibin subunit mRNAs during atresia of preovulatory follicles in the rat.

This study aimed to investigate the time course of disappearance of the mRNAs of the various subunits of inhibin in follicles which become atretic. An animal model was used in which atresia of preovulatory follicles could be studied in a chronological order. Injection of gonadotrophin-releasing hormone (GnRH) antagonist (20 microg) at the morning of pro-oestrus (P) blocked ovulation and the 10-...

Preovulatory changes in morphology of rabbit ovarian follicles.

To examine timed changes in the morphology of theca interna and granulosa cells of rabbit preovulatory follicles, mature female rabbits were injected with100 IU per kg of human chorionic gonadotropin (hCG) and follicles larger than1mn in diameter were excised for light and electron microscopic studies before and3, 6, 9and 12hr after hCG injection. Spindle-shaped theca interna cells had been tra...
