Question

Answer

Leydig cells are responsible for synthesizing and secreting testicular hormones called androgens and other immunologically competent cells are also present

Answer

Lydig cells
is the only one who synthesis and secretes testosterone
and Sertoli cell has many functions including nutrition but never secretes androgen

Answer

Testosterone is produced

by the Leydig cells in testes in men

It is an androgen, meaning that it stimulates the development of male characteristics

Answer

Testosterone is secreted by Leydig cells.
Testosterone is a hormone that plays a crucial role in the development and maintenance of male reproductive tissues and secondary sexual characteristics. It is primarily secreted by the Leydig cells, which are located in the interstitial tissue of the testes.
Leydig cells:
- Leydig cells are found in the testes, specifically in the interstitial tissue surrounding the seminiferous tubules.
- They are responsible for producing and secreting testosterone.
- The secretion of testosterone is regulated by luteinizing hormone (LH) from the pituitary gland.
Function of testosterone:
- Testosterone is essential for the development of male reproductive organs, such as the testes and prostate.
- It promotes the growth and maturation of sperm cells.
- Testosterone is responsible for the development of secondary sexual characteristics in males, such as facial and body hair, deepening of the voice, and increased muscle mass.
- It also plays a role in the regulation of libido (sex drive) and overall energy levels.
Sertoli cells and seminiferous tubules:
- Sertoli cells are found within the seminiferous tubules of the testes.
- They provide support and nourishment to developing sperm cells.
- Sertoli cells do not secrete testosterone.
Conclusion:
In summary, testosterone is primarily secreted by Leydig cells, which are located in the interstitial tissue of the testes. These cells play a crucial role in the production of testosterone, which is essential for male reproductive function and the development of secondary sexual characteristics. Neither Sertoli cells nor seminiferous tubules secrete testosterone.
