Question

Testosterone is produced by

• A. sertoli cells
• B. Leydig's cells
• C. oxyntic cells
• D. pituitary gland.

Answer 1

The Correct Option is B

Interstitial cells (or Leydig 's cells) are the cells interspersed between the seminiferous tubules of the testis. They secrete androgens including testosterone in response to stimulation by luteinizing hormone from the anterior pitutary gland. Androgens produce and maintain male characteristics and stimulate germinal epithelium to undergo spermatogenesis.

Answer 2

The male reproductive testis serves two purposes. In males, they serve as the major sex organs. and a bodily organ called an endocrine gland.

Seminiferous tubules and stromal or interstitial tissue make up the testis.

In the intertubular region, Leydig cells, also known as interstitial cells, create a class of hormones known as androgens. Testosterone is a significant androgen.

The epididymis, seminal vesicle, prostate gland, and other male accessory sex organs grow, mature, and operate under the control of androgens.

These hormones also promote aggression, low voice tone, axillary and facial hair growth, as well as the development of muscles.

In the process of spermatogenesis or the creation of spermatozoa, androgen has a significant stimulatory function.

Hence, the right response is option (B).

 

Answer 3

The testis' seminiferous tubules include cells called interstitial cells, also known as Leydig's cells. When the anterior pituitary gland's luteinizing hormone stimulates them, they release androgens like testosterone. Androgens help to develop and maintain male characteristics as well as promote spermatogenesis in the germinal epithelium.

 

The ideal decision is (B).

 

Answer 4

The main steroid hormone released by guys is testosterone. The growth of male reproductive organs like the testes and prostate in males is significantly influenced by the hormone testosterone. Moreover, it encourages auxiliary sexual traits. Inside the testicle, Leydig cells—also known as interstitial cells—are located close to the seminiferous tubules. Leydig cells are polyhedral in form, with an eosinophilic cytoplasm, an oversized conspicuous nucleus, and numerous lipid-filled vesicles. One to three conspicuous nucleoli and a sizable quantity of peripheral heterochromatin stained darkly are present in the nucleus. When luteinizing hormone is released, it creates testosterone as instructed (LH). In the process of producing testosterone, cholesterol is used. Testosterone controls the secretion from the accessory sex glands and spermatozoa production. The development and maturation of Leydig cells are dynamic and involve interaction between hormones and various additional factors.

 

So, the correct answer is option B.
