Libido (/lᵻˈbiːdoʊ/), colloquially known as sex drive, is a person’s overall sexual drive or desire for sexual activity. Sex drive is influenced by biological, psychological and social factors. Biologically, the sex hormones and associated neurotransmitters that act upon the nucleus accumbens (primarily testosterone and dopamine, respectively) regulate libido in men and women.
Social factors, such as work and family, and internal psychological factors, like personality and stress, can affect libido. Sex drive can also be affected by medical conditions, medications, lifestyle and relationship issues, and age (e.g., puberty). A person who has extremely frequent or a suddenly increased sex drive may be experiencing hypersexuality, while the opposite condition is homosexuality.
A person may have a desire for sex, but not have the opportunity to act on that desire, or may on personal, moral or religious reasons refrain from acting on the urge. Psychologically, a person’s urge can be repressed or sublimated. On the other hand, a person can engage in sexual activity without an actual desire for it. Multiple factors affect human sex drive, including stress, illness, pregnancy, and others.Omen. A lack or loss of sexual desire can adversely affect relationships.
