Detailed explanation-1: -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.
Detailed explanation-2: -Testosterone is required for processes that are critical for spermatogenesis including maintaining the BTB, supporting the completion of meiosis, the adhesion of elongated spermatids to Sertoli cells and the release of sperm.
Detailed explanation-3: -Male hormones The sex hormones of the male follow a much simpler pattern than do those of the female, although the same principle of interaction exists between the pituitary gland and the gonads.
Detailed explanation-4: -In adulthood iTT levels are 50–100-fold higher than serum levels. Intratesticular testosterone levels at 5–20% of normal can support spermatogenesis, and even low levels (e.g. 2% of normal adult levels) can support a degree of spermatogenesis in some species/individuals.
