Libido and hormones
1Department of Endocrinology and Metabolism, University of Pisa, Ospedale di Cisanello, Pisa, Italy.
Abstract:
Libido is the drive to have a sexual activity. Gonadal hormones play a major role in activating and maintaining libido in both men and women. Other hormones, though, interact with them in influencing sexuality, such as prolactin and also brain neurotransmitters. The role of hormones declines with age and sexuality becomes more mind-induced. Nevertheless, some aspects of sexuality remain linked to hormones. For example, a reduction of central arousability is typical of hypogonadal state. However, it is not clear at what level of androgen deficiency the loss of libido begins and if adequate external stimuli can overcome a partial deficiency.

Gonadal and Placental Hormones
In males, testosterone is the primary gonadal androgen. It plays a central role in the maturation of male reproductive organs — the penis and testes. Additionally, testosterone is instrumental in the development of secondary sexual characteristics — a deep voice as well as facial and pubic hair growth — and...

Major Hormones and Their Functions
Oxytocin, produced in the hypothalamus and released by the pituitary gland, plays a role in social bonding, childbirth, and lactation.
Target Cell Response to Hormones
Notably, the cellular response can be regulated by altering the number of receptors expressed in the cell. For example, prolonged exposure to elevated hormone levels results in a gradual decline or down-regulation in the number of receptors for that specific hormone on the cell surface. Conversely, in response to low hormone levels, cells may use up-regulation, producing an...
