Question

Spermatozoa are nourished during their development by
A. Sertoli cell
B. Interstitial cell
C. Connective tissue cell
D. Mast cell

Answer 1

Hint: These cells which provide nourishment during their development are also known as nurse cells and these cells are present in seminiferous tubules and in males they form as blood-testis barriers.

Complete answer:
In the testicular lobe, each seminiferous tubule is made up of male germ cells (spermatogonia), Sertoli cells, and Leydig cells. Meiosis divisions take place in the male germ cells and in which it leads to the formation of the sperms, while Sertoli cells provide nutrition to germ cells. The interstitial spaces are the regions outside the seminiferous tubules. These interstitial spaces constitute small blood vessels and interstitial cells or Leydig cells.

Additional Information:
Each testicular lobe contains one to three tightly coiled seminiferous tubules in which sperm are produced. Inside the seminiferous tubule, it is lined with two types of cells called male germ cells (spermatogonia) and Sertoli cells. Sertoli cells produce and secrete peptide hormone inhibin B into the circulation in response to stimulation of FSH. Sertoli cells are found in convoluted seminiferous tubules and are part of the blood-testicular barrier in males. They also play an important role in spermatogenesis, which is the production of sperm.
So, the correct answer is ‘Sertoli cells’.

Note: Semen feeds on Sertoli cells during sperm development.
A Sertoli cell (a kind of enduring cell) is a “nurse” cell in the testes which is a part of a seminiferous tubule and contributes to the process of spermatogenesis, the production of sperm. It is activated by follicle-stimulating hormone (FSH)which is secreted by the anterior pituitary and it also has an FSH receptor on its membranes.
