Atresia is a complex, hormonally controlled apoptotic process that depends dominantly on granulosa cell apoptosis. Follicular atresia is inhibited by follicle-stimulating hormone (FSH), which promotes follicle development. Once the follicle has developed, it secretes estrogen, which in high levels decreases secretions of FSH. Granulosa cell apoptosis is considered the underlying mechanism of follicular atresia, and has been associated with five ligand-receptor systems involved in cell death: WebOvarian aging, also interpreted as female reproductive aging, is mainly defined by the loss of quantity and quality of oocyte or follicular pool [12].
