Which of the following stimulates the secretion of testosterone?

Luteinizing hormone (LH) stimulates testosterone production.

Which hormone stimulates the secretion of testosterone?

In response to gonadotrophin-releasing hormone from the hypothalamus, the pituitary gland produces luteinising hormone which travels in the bloodstream to the gonads and stimulates the production and release of testosterone.

Which hormone stimulates the secretion of testosterone quizlet?

Luteinizing hormone stimulates the interstitial (Leydig) cells to secrete androgens, mostly testosterone.

What stimulates the secretion of testosterone during embryonic development?

Luteinizing Hormone/Chorionic Gonadotropin Receptor. Testicular (Leydig cell) testosterone secretion is stimulated by activation of the seven-transmembrane domain, G protein–coupled LHCGR.

How do the testes produce testosterone?

Testosterone is secreted by cells that lie between the seminiferous tubules, known as the Leydig cells. The testes also produce inhibin B and anti-Müllerian hormone from Sertoli cells, and insulin-like factor 3 and oestradiol from the Leydig cells.

  • Adrenocorticotrophic hormone (ACTH)
  • Thyroid-stimulating hormone (TSH)
  • Luteinising hormone (LH)
  • Follicle-stimulating hormone (FSH)
  • Prolactin (PRL)

Which hormone stimulates the secretion of testosterone and stimulates ovulation?

In males, LH stimulates testosterone release by the Leydig cells of the testes. In females, LH stimulates steroid release from the ovaries, ovulation, and the release of progesterone after ovulation by the corpus luteum [8].

What is the function of growth hormone?

Growth hormone stimulates production of insulin-like growth factor 1in the liver and other organs, and this acts on tissues in the body to control metabolism and growth. In addition to its effect on growth hormone secretion, growth hormone-releasing hormone also affects sleep, food intake and memory.

What is the function of the testosterone hormone?

Testosterone is a sex hormone that plays important roles in the body. In men, it’s thought to regulate sex drive (libido), bone mass, fat distribution, muscle mass and strength, and the production of red blood cells and sperm.

Which is the site of sperm production?

Sperm production in the testes takes place in coiled structures called seminiferous tubules. Along the top of each testicle is the epididymis. This is a cordlike structure where the sperm mature and are stored.

Is testosterone responsible for sperm production?

Sperm production is actually stimulated by hormones other than testosterone. Testosterone is required for sperm production, but the level in the testes where sperm are produced is many times higher than in the blood.

Are Leydig cells required for sperm production?

In males the interstitial cells of Leydig, located in the connective tissue surrounding the sperm-producing tubules of the testes, are responsible for the production and secretion of testosterone. In male animals that breed only seasonally, such as migratory birds and sheep, Leydig cells are prevalent in the testes…

What happens if testosterone is high in males?

Problems associated with abnormally high testosterone levels in men include: Low sperm counts, shrinking of the testicles and impotence (seems odd, doesn’t it?) Heart muscle damage and increased risk of heart attack. Prostate enlargement with difficulty urinating.

What is the target organ for testosterone?

What testicle produces sperm?

The epididymis is a long, coiled tube that rests on the backside of each testicle. It carries and stores sperm cells that are created in the testes. It’s also the job of the epididymis to bring the sperm to maturity — the sperm that emerge from the testes are immature and incapable of fertilization.
