Question

I.C.S.H. in male acts on?
A) Cells of Leydig
B) sertoli Cells
C) Spermatids
D) Spermatogonia

Answer 1

Hint: Leydig cells are interstitial cells located adjacent to the seminiferous tubules within the testes. The best-established function of Leydig cells is to supply the androgen, testosterone, under the pulsatile control of pituitary LH.

Complete answer:
In males, LH is additionally called as an interstitial cell-stimulating hormone (ICSH). It stimulates the assembly of testosterone by the leydig cells. It acts synergistically with FSH. ICSH representing interstitial-cell-stimulating hormone, Interstitial or Leydig cells are located within the animal tissue surrounding the seminiferous tubules.
Luteinizing hormone (LH) is produced and released within the anterior pituitary gland. This hormone is taken into account as a gonadotropin due to its role in controlling the function of ovaries in females and testes in males, which are referred to as the gonads.
They produce testosterone, the male steroid hormone liable for the expansion and maintenance of the cells of the germinal epithelium and therefore the development of secondary sex characteristics.
(A) Interstitial-cell stimulating hormone: a hormone produced by the anterior lobe of the pituitary that, within the male, stimulates the interstitial cells of the testes to supply testosterone; chemically just like LH of the feminine.
(B) Pharmacology- A billboard sort of this substance, obtained from the pituitary glands of pigs and sheep.

Hence, the right option may be a).

Note:
Leydig cells, also referred to as interstitial cells of Leydig, are found adjacent to the seminiferous tubules within the testicle. They produce testosterone within the presence of LH. Leydig cells are polyhedral in shape, and have an outsized prominent nucleus, an eosinophilic cytoplasm and various lipid-filled vesicles.
