AIIMS 2018 Zoology Spermatogenesis MCQ Question

Spermatozoa receive nutrition primarily from the epididymis, where they mature and are stored; the epithelial cells lining the epididymis secrete various substances, including glycoproteins and other nutrients essential for sperm development. Nurse glands, also known as Sertoli cells, support germ cells during spermatogenesis but do not directly nourish mature sperm. Interstitial cells (Leydig cells) produce testosterone, which is crucial for sperm production but does not provide nutrients to spermatozoa. Germ cells are the precursors to sperm and are involved in the process of spermatogenesis rather than providing nourishment to mature sperm.
