Perineal massage is a stretching technique you do in the final weeks of pregnancy to help the tissue between your vagina and anus become more flexible for birth. For first-time mothers, it cuts the risk of severe tearing (third- and fourth-degree lacerations) by roughly half, based on a meta-analysis published in the Journal of Family & Reproductive Health. Starting around week 34 and practicing consistently is what makes the difference.
Why It Works
The perineum is a small but critical patch of skin and muscle that stretches significantly as your baby’s head crowns during delivery. When that tissue isn’t elastic enough, it can tear or require a surgical cut (episiotomy). Regular massage softens the connective tissue and improves its elasticity, essentially training it to stretch under pressure rather than resist and tear.
The strongest evidence applies to first-time vaginal births. A Cochrane review found that women without a previous vaginal delivery who practiced perineal massage were significantly less likely to need stitches and less likely to receive an episiotomy. If you’ve already had a vaginal birth, the tissue tends to be more pliable on its own, so the tearing benefits are less dramatic. That said, the same Cochrane review found that women who had birthed vaginally before and still practiced the massage reported significantly less perineal pain three months after delivery.
When to Start and How Often
Begin at 34 weeks of pregnancy. Earlier than that isn’t necessary and hasn’t been studied for additional benefit. Aim for at least three to four sessions per week, with each session lasting a minimum of five minutes. Some protocols call for daily 10-minute sessions. Consistency matters more than marathon sessions: four five-minute practices will do more than one long one.
What You Need Before You Start
Preparation is simple but important:
- Wash your hands thoroughly and trim your fingernails short. Rough edges can scratch delicate tissue.
- Empty your bladder. A full bladder makes the area feel tighter and the massage less comfortable.
- Choose a lubricant. Good options include olive oil, almond oil, vitamin E oil, vegetable oil, or a water-based lubricant jelly. Do not use scented oils, synthetic oils, or anything with fragrance, as these can irritate sensitive vaginal tissue.
- Get comfortable. Sit propped up in bed with pillows under your hips, recline against a wall with your knees bent, or try it in a warm bath (the heat relaxes the muscles and makes stretching easier).
Step-by-Step Technique
Coat your thumbs generously with your chosen lubricant. Place one thumb about 1 to 1.5 inches inside your vagina, roughly to the first knuckle. Gently insert your other thumb alongside it.
Press both thumbs downward toward your anus, against the back wall of the vagina. Apply steady, firm pressure until you feel a distinct stretching sensation. This will likely feel like tingling, stinging, or mild burning. That’s normal and similar to the sensation you’ll feel during crowning. Hold this downward pressure for one to two minutes.
Next, slowly sweep both thumbs outward in a U-shaped motion, tracing from the bottom of the vaginal opening out to each side. Maintain enough pressure that you continue to feel the stretch as you move. The goal is a gentle, sustained pull on the tissue, not a rubbing or kneading motion. Repeat this U-shaped sweep for the remainder of your session.
Throughout the massage, focus on consciously relaxing the muscles of your pelvic floor. Your instinct will be to tense up against the stretch. Practicing relaxation into that pressure is part of the training, because during labor you’ll need to let those same muscles release as the baby descends.
If Your Partner Is Doing the Massage
A partner follows the same basic technique with one difference: they use their index fingers instead of thumbs, since the angle of approach is different when someone else is facing you. They should insert both index fingers about two inches (up to the second knuckle) into the vagina, press firmly downward toward the anus, and then sweep side to side in the same U-shaped motion. Communication is key here. Tell your partner when the stretch feels sufficient and when it feels like too much. The sensation should be intense but never painful.
What the Stretch Should Feel Like
Expect a burning or stinging feeling, especially during your first few sessions. This is the tissue stretching, not tearing. Over the course of two to three weeks, you’ll notice the same amount of pressure produces less discomfort as the tissue becomes more elastic. If you feel sharp pain, you’re pressing too hard or the tissue may be irritated. Ease off, add more lubricant, and try a gentler pressure.
The first session often feels awkward and uncomfortable. That’s completely normal. Most people find it becomes routine within a week, and the stretching sensation becomes familiar rather than alarming. That familiarity is actually part of the benefit: when you feel a similar burning during crowning, you’ll recognize it and know how to breathe through it instead of tensing up.
Who Should Skip It
Avoid perineal massage if you have an active vaginal infection such as thrush or herpes, as the massage could worsen irritation or spread infection. Placenta previa, risk of preterm labor, or any condition where your provider has advised against vaginal insertion are also reasons to hold off. If you have vaginal bleeding or ruptured membranes, do not perform the massage.
If you have scar tissue from a previous episiotomy or tear, perineal massage can actually help. Massage reduces stiffness and improves elasticity of scar tissue, which may make delivery smoother the second time around.
Practical Tips That Help
A warm bath or warm compress on the perineum for five to ten minutes before your session makes the tissue more pliable and the massage more comfortable. Some people find it easiest to do the massage after a shower as part of their evening routine, since they’re already relaxed and clean.
If reaching the area is difficult in late pregnancy (and it often is, given the belly), try placing one foot up on the edge of the bathtub or toilet seat to open up access. A mirror can help you see the area the first few times until the technique feels intuitive. And if you simply can’t reach comfortably, that’s a good time to hand the job over to your partner.
