Female sexual arousal disorder (FSAD) is a disorder characterized by a persistent or recurrent inability to attain sexual arousal or to maintain arousal until the completion of a sexual activity. The diagnosis can also refer to an inadequate lubrication-swelling response normally present during arousal and sexual activity. The condition should be distinguished from a general loss of interest in sexual activity and from other sexual dysfunctions, such as the orgasmic disorder (anorgasmia) and hypoactive sexual desire disorder, which is characterized as a lack or absence of sexual fantasies and desire for sexual activity for some period of time.Difficulties arise with this definition in terms of what constitutes an adequate lubrication-swelling response. There is no 'gold standard' regarding the length of time it should take to become aroused or the level of arousal that should be achieved. These responses may vary from one woman to another and are dependent on a range of factors, which include her general mood when sexual stimulation commences and her partner’s skill in stimulating her. There may also be differences in physiological and subjective levels of arousal, with some women reporting no feelings of sexual arousal despite evidence of vaginal vasocongestion and others reporting arousal in the absence of such evidence. The expectations and past experiences of clinicians and clients may also lead them to classify the same symptoms as female sexual arousal disorder in one woman but not in another.

Although female sexual dysfunction is currently a contested diagnostic, it has become more common in recent years to use testosterone-based drugs off-label to treat FSAD. While drug companies are technically not allowed to market these drugs for off-label uses, sharing the information with doctors at CME conferences has proved to be an effective way to navigate around the FDA approval process.
