Causes
The condition is sometimes classified as a psychiatric disorder. However, it can also be caused by medical problems such as diabetic neuropathy, multiple sclerosis, genital mutilation, complications from genital surgery, pelvic trauma (such as from a straddle injury caused by falling on the bars of a climbing frame, bicycle or gymnastics beam), hormonal imbalances, total hysterectomy, spinal cord injury, cauda equina syndrome, uterine embolisation, childbirth trauma (vaginal tearing through the use of forceps or suction or a large or unclosed episiotomy), vulvodynia and cardiovascular disease.
A common cause of situational anorgasmia, in both men and women, is the use of anti-depressants, particularly selective serotonin reuptake inhibitors (SSRIs). Post-SSRI sexual dysfunction (PSSD) is a name given to a reported iatrogenic sexual dysfunction caused by the previous use of SSRI antidepressants. Though reporting of anorgasmia as a side effect of SSRIs is not precise, studies have found that 17–41% of users of such medications are affected by some form of sexual dysfunction. Limited data has shown that the drug amantadine may help to relieve SSRI-induced sexual dysfunction.
Another cause of anorgasmia is opiate addiction, particularly to heroin. Beat icon William S. Burroughs chronicled this problem (amongst many others) in his novel Naked Lunch.
About 15% of women report difficulties with orgasm, and as many as 10% of women in the United States have never climaxed. Only 29% of women always have orgasms with their partner.
