Q

Familiarize the mechanism of androstenedione conversion

A

→ the luteinizing hormone (LH) causes the conversion of cholesterol into androstenedione within the theca layer
→ androstenedione crosses the basement membrane and enters the granulosa cell layer of the follicle to be converted into estradiol with the help of FSH
→ it then enters the systemic circulation to finally be converted into estrogen
