INTRODUCTION: Topical vaginal estrogens have been used in the management of postmenopausal vulvovaginal atrophy for some time, locally reintroducing exogenous estrogens to the estrogen-receptive tissues of the female urogenital tract following a decline in systemic levels. The postpartum period is similarly a state of relative estrogen depletion due to the antagonistic effect from raised prolactin levels throughout pregnancy and lactation; this is thought to contribute to post-delivery pelvic floor dysfunction and vaginal atrophy. Given the similar etiology, there may be a role for topical vaginal estrogens in postpartum women. MATERIAL AND METHODS: A systematic review was performed evaluating the use of topical vaginal estrogens in postpartum women. This was performed as per PRISMA guidelines, with articles screened from online databases from their inception to October 2025. RESULTS: Three studies were identified that met the inclusion criteria, including a total of 85 women. Two studies focused on the molecular and cellular composition of tissues from postpartum women using topical vaginal estrogens, and one double-blind randomized placebo-controlled trial primarily evaluated postpartum atrophy in the presence and absence of vaginal estrogens. Tissues exposed to estrogen appeared to have increased cellular proliferation, while the Vulval Assessment Score (VuAS), a patient-subjective validated scoring system for vaginal atrophy, was found to be lower in those using vaginal estrogen cream for 12 weeks. No statistically significant difference in bladder, bowel, or sexual function was noted. No serious adverse outcomes were reported, and the use of vaginal estrogens appeared acceptable to women. CONCLUSIONS: There is a paucity of data currently available regarding the use of topical vaginal estrogens in the post-partum period. Although likely safe for use, further evidence is required to be able to make firm conclusions about their efficacy for postpartum vaginal atrophy, and further high-quality trials are required in the future.
