Answer to Question 1
Males with erectile disorder become aroused and are interested in sexual activity but have trouble achieving or maintaining an erection. Females have trouble achieving or maintaining adequate lubrication. Men tend to more disturbed by arousal issues than women, and the disorder is exacerbated by age and becomes common after age 60 .
Orgasm disorders consist of the inability to have an orgasm despite adequate sexual desire and arousal, and are far more common in women than men. Approximately 20 percent of all women reliably experience regular orgasms during sexual intercourse, meaning that in order to make the diagnosis, it is important to take into account the couple's level of distress about the situation. Studies indicate that about 8 percent of men report delayed or nonexistent orgasms during sexual interactions but are unlikely to seek treatment for this condition.
Answer to Question 2
The treatment for gender dysphorias is controversial and can only been done in specialty clinics. The most common approach is sex reassignment surgery to change a person's physical anatomy to match his/her chosen gender identity. In order to undergo this surgery, individuals are typically asked to live in the opposite-sex role for one to two years and to be psychologically, financially, and socially stable. In some cases, hormones are also used to alter physical characteristics. Careful consideration of this surgery is important because approximately 7 percent of sex reassignment cases later regret surgery, and 2 percent may even attempt suicide after surgery.
