The most common problems related to sexual dysfunction in women include:
Inhibited sexual desire. This involves a lack of sexual desire or interest in sex. Many factors can contribute to a lack of desire, including hormonal changes, medical conditions and treatments (for example, cancer and chemotherapy), depression, pregnancy, stress, and fatigue. Boredom with regular sexual routines also may contribute to a lack of enthusiasm for sex, as can lifestyle factors, such as careers and the care of children.
Inability to become aroused. For women, the inability to become physically aroused during sexual activity often involves insufficient vaginal lubrication. This inability also may be related to anxiety or inadequate stimulation. In addition, researchers are investigating how blood flow problems affecting the vagina and clitoris may contribute to arousal problems.
Lack of orgasm (anorgasmia). This is the absence of sexual climax (orgasm). It can be caused by a woman's sexual inhibition, inexperience, lack of knowledge, and psychological factors such as guilt, anxiety, or a past sexual trauma or abuse. Other factors contributing to anorgasmia include insufficient stimulation, certain medications, and chronic diseases.
Painful intercourse. Pain during intercourse can be caused by a number of problems, including endometriosis, a pelvic mass, ovarian cysts, vaginitis, poor lubrication, the presence of scar tissue from surgery, or a sexually transmitted disease. A condition called vaginismus is a painful, involuntary spasm of the muscles that surround the vaginal entrance. It may occur in women who fear that penetration will be painful and also may stem from a sexual phobia or from a previous traumatic or painful experience.
