Q. What are the endocrine glands that regulate sexual activity in males? How does this regulation work and what are the involved hormones?
In males the sexual activity is regulated by the endocrine glands adrenals, hypophysis (pituitary) and gonads (testicles).
The FSH (follicle-stimulating hormone) secreted by the adenohypophysis acts upon the testicles stimulating the spermatogenesis and The LH (luteinizing hormone) another adenohypophyseal hormone stimulates the production of testosterone by the testicles too. Testosterone whose production intensifies after the beginning of puberty acts in several organs of the body and it is responsible for the appearing of the male secondary sex characteristics body hair, beard, deep voice, increase of the muscle and maturation of genitalia, osseous mass, and so on. Testosterone also stimulates spermatogenesis.
