Pelvic floor training after birth improves sex life, pooled trials find

Pregnancy and childbirth leave a weakness and laxity in the pubourethral and external urethral ligaments, structures that play an important role in women's sexual function and quality of life. Pelvic floor muscle training is widely taught after birth, and some evidence suggests it can strengthen the pelvic muscles and prevent sexual dysfunction. What had not been established was whether the trials on this, taken together, actually show a benefit for postpartum sexual function and quality of life rather than just continence. This review set out to answer that by pooling the available clinical evidence.

The researchers searched PubMed, CINAHL, Medline, Scopus, Google Scholar citations and the Persian databases SID and Iran Medex for experimental and quasi-experimental studies in English and Persian. The search returned 347 titles and abstracts, which two independent researchers narrowed down to 12 eligible articles using a pre-defined checklist. Risk of bias was assessed with the Cochrane tool, and the results were combined in a meta-analysis comparing women who did pelvic floor exercise with control groups on sexual function, sexual quality of life and general quality of life.

Women who trained their pelvic floor scored meaningfully better on sexual function than controls, with a pooled standardised difference of 0.462. The largest effect appeared for sexual quality of life, where the pooled difference was 1.294. General quality of life also improved, though more modestly, at 0.232. All three outcomes reached statistical significance, and the authors note the benefits applied to women after both first and subsequent births. The consistent caveat was that the included studies varied substantially in how the training was delivered, producing significant disagreement between them on the size of the effect.

Pelvic floor training already has an established place in postpartum care, mostly framed around preventing incontinence. This review extends the case by showing the pooled trial evidence also points towards better sexual function and quality of life, which is how many women would actually experience the benefit. It does not settle the question of which training method, duration or intensity works best, because the trials differed widely on exactly those points. The authors are explicit that although the majority of studies were positive, more high-quality randomised trials are needed before the size of the benefit can be stated with confidence.

For anyone recovering from childbirth, this is a reason to see pelvic floor exercises as relevant to sexual wellbeing and overall quality of life, not only to bladder control. The evidence points consistently in a positive direction across a dozen trials, which is more than many postpartum interventions can claim. At the same time, the trials disagreed on how much improvement to expect, so a modest and gradual benefit is the honest expectation. Anyone with specific postpartum concerns would still sensibly discuss them with a midwife, physiotherapist or doctor.
