A new systematic review and meta-analysis published in The Journal of Sexual Medicine finds that breast reduction surgery is associated with improvements in sexual function for many women. The study, led by researchers based in Iran, synthesised data from 13 eligible studies involving 676 participants across several countries, including Brazil, Turkey, the United Kingdom, the United States, Italy, Iran, Poland and Spain.
Researchers aimed to clarify how reducing breast size affects postoperative sexual function in healthy women with symptomatic macromastia. Studies focusing on cancer-related breast surgery or gender-affirming procedures were excluded to keep the focus on the physical and psychological effects of the condition itself.
Across the 13 studies, nine reported improvements in sexual function after surgery, while four found no meaningful change. Many of the included studies used the Female Sexual Function Index to measure aspects such as sexual desire, physiological arousal, lubrication, orgasm, satisfaction and pain, with improvements reported across these domains.
For example, one study noted a drop in clinical sexual dysfunction from 62.5% before surgery to 21.4% afterward. A United States prospective study within the review showed improvements in sexual function in more than two-thirds of the women tracked.
Because eight of the studies employed similar standardised instruments, the data permitted a meta-analysis. This analysis indicated a mean increase of 13.27% in sexual function scores among patients following breast reduction.
The authors propose several physiological pathways for these results. Physically, reducing breast volume can lessen chronic pain and other physical restrictions, relieving a persistent distraction during sexual arousal. There is also some evidence that removing excess tissue may normalise sensory nerve distribution in the breast, with the nipple-areola complex playing a role in triggering oxytocin release, a hormone linked to arousal and bonding. Modern techniques emphasise nerve preservation to maintain sensation where possible.
Psychologically, the surgery often prompts a shift in body image. Large breasts can contribute to “spectatoring”—a habit of continually monitoring appearance during intimacy—which can fuel anxiety and reduce sensory engagement. By alleviating appearance-related anxiety, breast reduction may enable fuller engagement in sexual experiences, creating a positive feedback loop that supports improved self-esteem and sexual satisfaction.
The review notes that mental health benefits may extend beyond the bedroom. A large database study cited in the discussion reported a fall in prescriptions for certain antidepressants and anti-anxiety medications from 46.3% to 29.5% among patients after breast reduction, suggesting broader psychological relief.
Partner responses also appear influential. Positive partner reactions to the physical changes can enhance the sexual benefit of the procedure, while critical or indifferent responses may dampen potential gains. In one study, improvements in women’s sexual function were accompanied by increased sexual function scores in their partners as well.
Despite these findings, the researchers caution that the evidence base is limited. The majority of included studies were observational, with small samples and short follow-up periods—typically three to six months—limiting conclusions about long-term effects or causality. There was also substantial variation in study design and surgical techniques, and the data did not allow for conclusions about how specific surgical parameters, such as tissue volume removed or method used, influence outcomes.
Looking ahead, the authors emphasise the need for more diverse populations and for studies that record surgical details to help clinicians tailor advice on nerve preservation and sensory outcomes. They call for longer-term research to determine whether observed sexual and psychological benefits persist over time.
