PATHOLOGY

Detailed explanation-1: -The testes synthesize two essential products: testosterone, needed for the development and maintenance of many physiological functions including normal testis function; and sperm, needed for male fertility.

Detailed explanation-2: -Luteinizing hormone (LH) stimulates testosterone production. If too much testosterone is produced, the hypothalamus alerts the pituitary gland to make less LH, which tells the testes to decrease testosterone levels.

Detailed explanation-3: -The brain’s hypothalamus and pituitary gland control testosterone production, which is produced in the gonads where the Leydig cells make and secrete testosterone.

Detailed explanation-4: -The testes (male gonads) secrete the steroid and protein hormones. While the testicular steroid hormones are testosterone, dihydrotestosterone and estrogen, the protein hormones are inhibins, activins and anti-Mullerian hormone (Mullerian-inhibiting substance).

Detailed explanation-5: -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.
