Androstenedione is further converted to either testosterone or oestrogen.
In males, conversion of androstenedione to testosterone requires the enzyme 17β-hydroxysteroid dehydrogenase.
In females, androstenedione is released into the blood by theca cells. Conversion of androstenedione to estrogen (e.g., oestrone and oestradiol) requires the enzyme aromatase. Androstenedione is a substrate for oestrogen production in granulosa cells which produce aromatase. Thus, theca cells and granulosa cells work together to form oestrogens.
