Question

Testosterone is produced by
A. Sertoli cells
B. Leydig cells
C. Oxyntic cells
D. Pituitary gland

Answer 1

Hint: These are interstitial cells that are found adjacent to the seminiferous tubules. These cells help in the regulation of the secondary sexual characters (occurs during puberty).

Complete answer:
-Sertoli cells: Sertoli cells are epithelial supporting cells of the seminiferous tubules. These cells are tall simple columnar cells, and these cells are also known as nurse or mother cells which helps in the process of spermatogenesis. These Sertoli cells secrete various proteins involving androgen-binding protein and hormones such as inhibin.
-Leydig cells: They are also known as interstitial cells of Leydig which are located adjacent to seminiferous tubules. These cells are best known for the secretion of hormones such as androgen, testosterone (in the presence of a hormone known as a luteinizing hormone) which are essential for spermatogenesis.
-Oxyntic cells: Oxyntic cells are also called parietal cells which are located in the neck and fundus of gastric glands of the fundus- body region of the stomach. These cells produce the best-known component of gastric juice i.e. HCL (hydrochloric acid).
-Pituitary gland: The pituitary gland is a small-sized gland that plays a vital role in regulating important body functions and general well-being. These glands are referred to as the body’s master gland as it controls the activity of most other hormone-secreting glands. These glands produce the luteinizing hormone (LH), follicle-stimulating hormone (FSH), growth hormone (GH), and adrenocorticotropic hormone (ACTH).

Hence, the correct answer is option (B).

Note: Testosterone is an essential hormone that helps in the normal sperm development and sperm count. They activate the genes which are present in the Sertoli cells which further promote differentiation of spermatogonia.
