Perineal massage is a simple stretching technique you do in the final weeks of pregnancy to help prepare the tissue between your vagina and anus for childbirth. Starting at week 34, about five minutes a day can reduce your chance of needing an episiotomy by roughly 16%, based on a Cochrane review of four trials involving nearly 2,500 women. The technique mimics the stretching that happens as your baby’s head crowns during delivery, helping the tissue become more flexible before labor begins.
Why It Works
The perineum is a small but important area of muscle and tissue that sits between the vagina and the anus. During vaginal delivery, this tissue needs to stretch dramatically as the baby’s head passes through. If the tissue isn’t flexible enough, it can tear on its own or require a surgical cut (episiotomy) to make room.
Perineal massage gradually increases the elasticity of this tissue over several weeks. It also helps you get familiar with the intense stretching and burning sensation you’ll feel during crowning, so you’re less likely to tense up during delivery. The Cochrane review found that women who practiced perineal massage were significantly less likely to have an episiotomy, though it did not reduce the rate of first- or second-degree tears. The benefit appears to come from conditioning the tissue so it can stretch more effectively under pressure.
When and How Often to Start
Begin at 34 weeks of pregnancy. Aim for about five minutes per session, once a day. If daily feels like too much at first, working up to four or five times a week is a reasonable starting point. Consistency matters more than session length. The tissue adapts gradually, and most women notice it feels less uncomfortable after the first week or two of practice.
What You Need Before You Start
Wash your hands thoroughly and trim your nails short to avoid scratching the tissue. You’ll need a lubricant to reduce friction. Good options include organic sunflower oil, grapeseed oil, coconut oil, almond oil, or olive oil. Water-based personal lubricants like K-Y Jelly also work well. Your body’s own vaginal lubrication is fine if that feels more comfortable.
Avoid synthetic oils, baby oil, mineral oil, and petroleum jelly. These can irritate vaginal tissue or trap bacteria.
Find a comfortable position. Many women sit propped up against pillows on a bed with knees bent and legs apart, or stand with one foot elevated on a stool or the edge of the bathtub. A warm bath or shower beforehand can help relax the muscles and make the tissue more pliable. Some women find a mirror helpful the first few times to see what they’re doing.
Step-by-Step Technique
Apply a generous amount of lubricant to your thumbs and to the perineal tissue around the lower part of your vagina.
Insert your thumbs about 3 to 4 centimeters (roughly 1.5 inches) inside the vagina, resting them against the back wall, which is the side closest to your anus. If you’re doing this yourself, your thumbs will naturally point downward.
Press firmly downward toward the anus and hold for about one minute. You should feel a deep stretching sensation, and possibly a tingling or burning feeling. This is normal. It’s similar to what crowning feels like during labor. Breathe deeply and focus on relaxing your pelvic floor muscles rather than tensing against the pressure.
While maintaining that downward pressure, begin sweeping your thumbs in a U-shaped motion. Move from the 6 o’clock position (straight down toward the anus) out to 3 o’clock on one side and 9 o’clock on the other. Think of tracing the bottom half of a clock face. Continue this U-shaped sweeping motion for two to three minutes, gently stretching the vaginal wall outward at each point along the way.
The goal is to stretch the tissue open as wide as you comfortably can. You should feel a significant stretch, but not sharp pain. Over the weeks, you’ll notice the tissue becoming more flexible and the burning sensation decreasing. That adaptation is exactly the point.
How a Partner Can Help
As your belly grows in the last weeks of pregnancy, reaching comfortably can become difficult. A partner can perform the massage using their index fingers (or thumbs) instead of yours. The technique is the same: clean hands, lubricated fingers inserted into the lower part of the vagina, pressing downward and sweeping in a U-shape.
Communication is essential here. Your partner should be guided entirely by your feedback on how much pressure feels right. The sensation should be a deep stretch, not pain. Start with lighter pressure and increase gradually as you direct. It helps to agree on simple cues beforehand, like “more,” “less,” or “hold there,” so you can stay relaxed rather than having to explain in detail mid-session.
What It Should and Shouldn’t Feel Like
A stretching or burning sensation is expected and actually desirable. It means the tissue is being challenged enough to adapt. Sharp, stabbing pain is not normal. If you feel that, reduce the pressure or reposition your fingers. The first few sessions often feel the most intense. Most women report that by the second or third week, the same amount of pressure produces noticeably less discomfort.
Some mild soreness after the first few sessions is common. If soreness lasts more than a day, or if you notice any bleeding, swelling, or unusual discharge, stop and check with your midwife or doctor before continuing.
When to Skip It
Perineal massage is not appropriate in every situation. You should avoid it if you have an active vaginal infection (such as a yeast infection or bacterial vaginosis), vaginal bleeding, placenta previa, or if your membranes have ruptured (your water has broken). If you have a history of preterm labor or have been advised to avoid vaginal penetration for any reason during your pregnancy, check with your care provider before starting.
Realistic Expectations
Perineal massage reduces your likelihood of needing an episiotomy, and that benefit is well supported by evidence. What it doesn’t do is guarantee you won’t tear. The Cochrane review found no significant difference in first- or second-degree tears between women who massaged and those who didn’t. Tearing during childbirth depends on many factors beyond tissue flexibility, including baby’s size, speed of delivery, and birthing position.
Still, the practice has a second, less measurable benefit: familiarity. Women who’ve done perineal massage often report feeling more prepared for the sensation of crowning. That mental preparation can help you stay calm, breathe through the stretch, and follow your midwife’s guidance on when to push and when to pause, all of which can influence how delivery unfolds.
