Female Sexual Arousal Disorder (FSAD) is a debilitating sexual dysfunction. It can cause problems in relationships and feelings of inadequacy and helplessness.
By definition, FSAD is an inability to achieve arousal or lubrication during intercourse, the inability to orgasm, and/or the lack of desire for sexual activity. Other symptoms may include Dyspareunia (pain during and/or after sex) or Vaginismus (when the vaginal muscles spasm involuntary, making penetration difficult or impossible). Sometimes, even if desire is present, a woman will be unable to find herself physically aroused or the thought of potential pain during intercourse makes her more inclined to avoid it.
FSAD can be caused by numerous variables. Menopause is one of the most common causes of FSAD. Pregnancy is also quite common, particularly in the time directly after the child is born. Other factors include stress, surgeries which affect hormones or feelings regarding womanhood (hysterectomy, mastectomy), medications (especially anti-depressants or birth control), low self-esteem, emotional trauma, even alcohol, drugs or smoking.
Usually, when a woman feels she may be suffering from FSAD, a health practitioner will inspect for any vaginal or pelvic abnormalities. Sometimes, pain during intercourse can be caused by a cyst.It is important to ensure that pain is not caused by something severe.
Sometimes, treatment simply involves using alternative tactics for arousal, including erotic materials and/or toys. A partner may be advised to use more foreplay/massage before sex, or to change position to allow easier penetration with less pain.
If FSAD has a root in the emotions, as are common if there is a history of sexual abuse, therapy may be administered to help the patient overcome her fears or doubts. Most therapists will also recommend open communication between the woman and her partner, to ensure patience, understanding and emotional intimacy.
According to the Gale Encyclopedia of Medicine (2002), most women who have sought treatment by one means or another have been able to achieve a healthy sex life, especially those who seek holistic treatments with roots both in the physical and mental.

I was kind of confused for a minute when I saw the term FSAD, as I know that the word SAD is also known for Seasonal Affective Disorder, which also affects many women.
