Question

Leydig cells in adult mammals produce

• A. Estrogen
• B. Testosterone
• C. Progesterone
• D. Follicle stimulating hormone

Answer 1

The correct option is B Testosterone

Leydig cells, also known as interstitial cells of Leydig, are found adjacent to the seminiferous tubules in the testicle. They produce testosterone in the presence of luteinizing hormone (LH). Leydig cells are polyhedral in shape, display a large prominent nucleus, an eosinophilic cytoplasm and numerous lipid-filled vesicles. 'Adult'-type Leydig cells differentiate in the post-natal testis and are quiescent until puberty

So, the correct answer is 'testosterone'
