Ovarian follicular steroid synthesis
Diagramatic representation of the steroidogenic pathways in human pre-luteinized follicles (A) and post luteinized follicles (B), demonstrating granulosa dependence on theca cell testosterone steroidogenesis in pre-luteinized follicles and the de novo synthesis of progesterone from cholesterol due to induction/up-regulation of CYP11A and 3βHSD after the gonadotropin surge in post luteinized follicles.
The principle steroid product of luteinized pre-ovulatory granulosa is progesterone, a differentiation triggered by the gonadotropin surge. However, absolute steroid levels are associated with follicular size, not oocyte maturation/ability to fertilize.
