Hypoactive Sexual Desire Disorder (HSDD) is a medical condition that affects both men and women. It is characterized by a persistent or recurrent lack of sexual desire or interest. However, there are several other synonyms for this condition, including inhibited sexual desire, low libido, sexual aversion, and sexual disinterest. These terms are used interchangeably to describe the same condition of reduced sexual desire. Regardless of what it is called, HSDD can significantly affect a person's quality of life and their relationship with their partner. If you believe you have any of these symptoms, it is important to speak to a healthcare professional.
