Question

Which of the following statements can be related to Leydig cells?

• A. They stimulate spermatogenesis.
• B. They stimulate oogenesis.
• C. They promote lactation.
• D. None of the above

Answer 1

The correct option is A They stimulate spermatogenesis.

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). In the absence of testosterone, spermatogenesis does not proceed beyond the meiosis stage. Thus, Leydig cells stimulate spermatogenesis by producing testosterone which stimulates spermatogenesis.

So, the correct answer is 'They stimulate spermatogenesis'.
