Final answer:
Testosterone in the ovaries and fat cells is synthesized from androstenedione. This is regulated by hormones such as LH and FSH from the pituitary gland, with the ovaries also producing estradiol and progesterone.
Step-by-step explanation:
In the ovaries and fat cells, testosterone is produced from c) Androstenedione.
Testosterone production in the ovaries and fat cells involves conversion from androstenedione, which is a precursor hormone. In the ovaries, under the influence of luteinizing hormone (LH) and follicle-stimulating hormone (FSH), produced by the pituitary gland, androstenedione is synthesized by the theca cells and can be converted into testosterone. Testosterone is an androgen, which is essential for both males and females, though in different concentrations.
While the testes in males are known for higher testosterone production, in females, the ovaries produce estradiol and progesterone, along with small amounts of testosterone, which is necessary for normal reproductive and bodily functions such as maintaining muscle mass and bone density. Additionally, fat cells can convert androstenedione to testosterone via a process known as peripheral aromatization.
