Iron deficiency and sexual dysfunction in women

Sexual dysfunction negatively affects approximately 40% to 50% of adult women across various stages of life. Common risk factors include sexual traumas, relationship problems, chronic conditions, medication side effects, and poor physical health, including iron deficiency.

This review summarizes a presentation from a symposium that discussed the types and causes of sexual dysfunction at key times in women's lives, focusing on the relationship between iron deficiency and sexual dysfunction.

The symposium was held at the XV Annual European Urogynaecological Association Congress, Antibes, France, in October 2022. Symposium content was identified through literature searches of PubMed. Original research, review articles, and Cochrane analyses discussing sexual dysfunction in association with iron deficiency/anemia were included.

Iron deficiency in women is commonly caused by abnormal uterine bleeding, but women may develop iron deficiency anemia (IDA) because of increased iron needs or reduced iron intake/absorption. Treatment with oral iron supplementation has been shown to improve sexual function in women with IDA. Ferrous sulphate is considered as a standard of care for oral iron treatment; prolonged-release iron formulations have improved tolerability, enabling lower doses and better tolerability.

IDA and sexual dysfunction are related, so the identification of sexual dysfunction or iron deficiency in a woman should prompt an investigation of the other condition. Testing for iron deficiency is an inexpensive and simple step that can be routinely included in the workup of women with sexual dysfunction. Once identified, IDA and sexual dysfunction in women should be treated and followed to optimize quality of life.
