Psychological and Physical Factors
Psychological factors
Reduction in libido can occur from psychological causes such as loss of privacy and/or intimacy, stress, distraction or depression. It may also derive from the presence of environmental stressors such as prolonged exposure to elevated sound levels or bright light. Other causes include:
* depression
* stress or fatigue
* childhood sexual abuse, assault, trauma, or neglect
* body image issues
* sexual performance anxiety
Physical factors
Physical factors that can affect libido include: endocrine issues such as hypothyroidism, levels of available testosterone in the bloodstream of both women and men, the effect of certain prescription medications (for example proscar (a.k.a. finasteride) or minoxidil), various lifestyle factors and the attractiveness and biological fitness of one's partner. Inborn lack of sexual desire, often observed in asexual people, can also be considered a physical factor.
Other Physical factors(Female): Menstrual cycle
Women's libido is correlated to their menstrual cycle. Many women experience heightened sexual desire in the several days immediately before ovulation.
Causes of low libido include not getting enough sleep, unresolved conflicts within the relationship, and suboptimal amounts of testosterone in the body
