Sexology is the interdisciplinary science that focuses on diverse aspects of human sexual behaviour and sexuality, including sexual development, relationships, intercourse, sexual dysfunction, sexually transmitted diseases. Both men and women can experience sexual dysfunction. It is a relatively common problem, with more than 40 percent of women and 30 percent of men reporting some level of dysfunction. It can be caused by physical problems and medical conditions, such as heart disease and hormone imbalances, or by psychological problems, like anxiety, depression and the effects of past trauma.
Physical causes: Many physical and/or medical conditions can cause problems with sexual function. These conditions include diabetes, heart and vascular (blood vessel) disease, neurological disorders, hormonal imbalances, chronic diseases such as kidney or liver failure, and alcoholism and drug abuse. In addition, the side effects of some medications, including some antidepressant drugs, can affect sexual function.
Psychological causes: These include work-related stress and anxiety, concern about sexual performance, marital or relationship problems, depression, feelings of guilt, concerns about body image and the effects of a past sexual trauma.
