Low Sex Drive

What is it?

Hypoactive sexual desire disorder (HSDD) is defined as persistently low or absent sexual desire causing personal distress. It is the most common female sexual complaint — affecting up to 40% of women at some point — and is also prevalent in men (15–25%), particularly those with low testosterone or depression. Major causes include low testosterone (both sexes), menopause and estrogen deficiency, hypothyroidism, depression, anxiety, relationship factors, and medications (notably SSRIs, antihypertensives, and hormonal contraceptives). Thorough evaluation considers hormonal, psychological, and relational factors before treatment.
