Postpartum Vaginal Dryness: Why It Happens and How to Feel Better

Short answer: Postpartum vaginal dryness is usually caused by high prolactin while breastfeeding, which keeps estrogen low and creates menopause-like dryness. It is very common in breastfeeding women and usually improves after weaning; lubricants are first-line in the meantime.

Having a baby changes your body in countless ways, and vaginal dryness is one that few people warn you about. If intimacy feels uncomfortable after birth, or you notice dryness, itching or tenderness, there’s a clear reason, and it’s usually temporary.

Why it happens

Estrogen is very high during pregnancy and then drops sharply after delivery. If you’re breastfeeding, the hormone prolactin, which drives milk production, keeps estrogen low for as long as you nurse. Low estrogen means thinner, drier and more sensitive vaginal tissue, similar to what happens during menopause.

Other factors that can add to it

• Healing from tears, stitches or an episiotomy
• Fatigue, stress and lack of sleep, which affect arousal
• Some forms of hormonal birth control, especially progestin-only methods
• Pelvic floor muscle changes after pregnancy and delivery

How long does postpartum vaginal dryness last?

For most women, postpartum dryness improves within months, usually once periods return or breastfeeding slows or ends and estrogen recovers. In a 2025 review of 65 studies, pain during sex was reported by about 60% of women at 3 months after birth, 40% at 6 months and 29% at 12 months [2]. If you are still exclusively breastfeeding, dryness can last as long as nursing does. You don’t have to wait it out uncomfortably: a lubricant and a moisturizer help in the meantime.

Breastfeeding and vaginal dryness

Breastfeeding is one of the most common causes of vaginal dryness after birth. Prolactin, the hormone that drives milk production, keeps estrogen low, so the vaginal tissue can become thin and dry, much like after menopause. Researchers now call this the genitourinary syndrome of lactation [1].

• It is very common: about 54% of breastfeeding women report vaginal dryness [2]. In one study, signs of vaginal atrophy were found in 58% of breastfeeding women at their postpartum check versus 17% of those not breastfeeding [3].
• It is temporary: dryness usually improves as feeds space out, periods return or you wean.
• You don’t have to stop breastfeeding: lubricants and vaginal moisturizers are compatible with nursing. If sex is painful, ask your provider about low-dose vaginal estrogen, which is generally considered compatible with breastfeeding.

What helps

• Use a gentle lubricant during intimacy. Water-based and silicone-based lubricants are both good choices. Here’s how to choose.
• Try a vaginal moisturizer every few days for ongoing comfort
• Take it slow. Allow more time for arousal and communicate with your partner.
• Avoid irritants like scented soaps, wipes and douches
• See a pelvic floor physical therapist if you have pain, pressure or leaking

If you’re breastfeeding, ask your healthcare provider before starting any new intimate product, including hormone-free serums like AIRS.

When to call your provider

Talk with your OB-GYN or midwife if sex stays painful after you’ve healed, if you notice bleeding, unusual discharge or a bad odor, or if a tear or incision seems not to be healing.

FAQ

Is it normal to have vaginal dryness while breastfeeding?

Yes. Low estrogen during breastfeeding commonly causes dryness. It usually improves after weaning.

When is it safe to have sex after giving birth?

Many providers suggest waiting until after your postpartum checkup, often around 6 weeks, but follow your own provider’s advice.

What the research says

• Researchers have proposed the term genitourinary syndrome of lactation (GSL) to describe menopause-like vaginal and urinary symptoms during breastfeeding [5].
• High prolactin during lactation suppresses estrogen, and vaginal dryness has been reported in up to 46% of breastfeeding women [5].
• Lubricants are suggested as first-line care, with vaginal estrogen or DHEA as options for persistent symptoms [5].

How long does postpartum vaginal dryness last?

It usually improves within a few months, as periods return or breastfeeding slows or ends. In a 2025 review, pain during sex affected about 60% of women at 3 months postpartum, 40% at 6 months and 29% at 12 months. A lubricant and vaginal moisturizer help in the meantime.

Why does breastfeeding cause vaginal dryness?

Breastfeeding raises prolactin, which keeps estrogen low. Low estrogen thins and dries the vaginal tissue, similar to menopause. It is temporary and usually improves after weaning or when periods return.
