Libido and hormones
1Department of Endocrinology and Metabolism, University of Pisa, Ospedale di Cisanello, Pisa, Italy.
Hormones like gonadal steroids significantly influence libido, but their role diminishes with age, making sexuality more psychological. The exact level of androgen deficiency causing libido loss and if stimuli can compensate remain unclear.
Area of Science:
- Endocrinology
- Neuroscience
- Human Sexuality
Background:
- Libido, or sex drive, is influenced by gonadal hormones, prolactin, and neurotransmitters.
- Hormonal influence on sexuality decreases with age, with psychological factors becoming more prominent.
- Central arousability reduction is characteristic of hypogonadal states.
Purpose of the Study:
- To explore the intricate relationship between hormones and libido.
- To investigate the age-related decline in hormonal influence on sexual drive.
- To clarify the threshold of androgen deficiency impacting libido and the potential for external stimuli to compensate.
Main Methods:
- Review of existing literature on hormonal and neurochemical regulation of libido.
- Analysis of age-related changes in sexual function and hormonal profiles.
- Exploration of the interplay between central nervous system and hormonal factors in sexual arousal.
Main Results:
- Gonadal hormones are crucial for libido, with other hormones and neurotransmitters playing interactive roles.
- While hormonal influence wanes with age, certain aspects of sexual function remain hormone-dependent.
- The precise androgen level triggering libido loss and the efficacy of stimuli in partial deficiencies require further elucidation.
Conclusions:
- Hormonal regulation of libido is complex and interacts with neurobiological and psychological factors.
- Understanding the hormonal basis of libido is essential, particularly in the context of aging and hypogonadism.
- Further research is needed to define the quantitative relationship between androgen levels, libido, and compensatory mechanisms.

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...
