ANATOMY

Detailed explanation-1: -Follicle-stimulating hormone (plus testosterone) causes the testes to produce sperm. Testosterone is responsible for the development of secondary sex characteristics, features of male development (including characteristics that are not part of the reproductive system, such as facial hair growth and voice change).

Detailed explanation-2: -Androgens are the group of sex hormones that give men their ‘male’ characteristics (collectively called virilisation). The major sex hormone in men is testosterone, which is produced mainly in the testes.

Detailed explanation-3: -Three hormones are the principle regulators of the male reproductive system: follicle-stimulating hormone (FSH) stimulates spermatogenesis; luteinizing hormone (LH) stimulates the production of testosterone; and testosterone stimulates the development of male secondary sex characteristics and spermatogenesis.

Detailed explanation-4: -Your hypothalamus releases gonadotropin-releasing hormone (GnRH), which triggers your pituitary gland to release luteinizing hormone (LH). LH then travels to your gonads and stimulates the production and release of testosterone.

Detailed explanation-5: -Results: Testosterone has a primary role in controlling and synchronizing male sexual desire and arousal, acting at multiple levels. Accordingly, meta-analysis indicates that testosterone therapy for hypogonadal individuals can improve low desire and erectile dysfunction.
