Perineal massage starting around 34 to 35 weeks of pregnancy is the most well-supported way to prepare the tissue between your vagina and rectum for the stretching of childbirth. In one clinical trial, only 31% of women who received perineal massage needed an episiotomy, compared to nearly 70% in the group that didn’t. Beyond massage, a combination of pelvic floor exercises and techniques your birth team can use during labor all contribute to reducing your risk of tearing.
Why Perineal Preparation Matters
During delivery, the perineum needs to stretch dramatically to allow your baby’s head to pass through. If the tissue isn’t flexible enough, it can tear on its own or your provider may perform an episiotomy (a surgical cut to widen the opening). Most tears are minor, but third and fourth degree tears extend into deeper muscle and can affect recovery for weeks or months. The goal of perineal preparation isn’t to guarantee you won’t tear. It’s to make the tissue more elastic and pliable so it stretches more easily when the time comes.
When to Start
The Royal College of Obstetricians and Gynaecologists recommends beginning perineal massage from 35 weeks onward, while other guidelines suggest starting at 34 weeks. Either way, you’re looking at roughly five to six weeks of consistent practice before your due date. Starting earlier than 34 weeks hasn’t been shown to add benefit, and perineal bulging exercises (described below) should only be practiced in the final three weeks of pregnancy to avoid putting excessive pressure on pelvic floor structures too early.
How to Do Perineal Massage
Each session takes about four to five minutes, and you should aim for three to four times per week. You can do it yourself or have your partner help. Here’s the basic technique:
- Wash your hands thoroughly and trim your nails short to avoid scratching the tissue.
- Choose a lubricant. Good options include organic sunflower oil, grapeseed oil, coconut oil, almond oil, or olive oil. Water-soluble personal lubricants like K-Y Jelly also work well. Avoid synthetic products like baby oil, mineral oil, or petroleum jelly.
- Get comfortable. A semi-reclined position, propped up with pillows, or one foot elevated on a stool both work. Some people find it easiest in the shower or bath when the tissue is already warm and relaxed.
- Insert your thumbs (or your partner’s index fingers) about one to two inches into the vagina, pressing downward toward the rectum.
- Apply steady pressure and sweep in a U-shaped motion from side to side along the lower half of the vaginal opening. You should feel a stretching or mild burning sensation, but not sharp pain.
- Hold the stretch at each point for about one to two minutes, then continue the sweeping motion for the remainder of the session.
The sensation may feel intense at first. That mild burning is actually useful because it mimics the “ring of fire” feeling during crowning, helping you learn to relax into the stretch rather than tense against it. Over a few weeks, you’ll notice the tissue becomes noticeably more supple.
Perineal Bulges and Deep Squats
Massage isn’t the only way to prepare. Two complementary exercises help lengthen and relax the pelvic floor muscles that surround the perineum.
Deep squats stretch the perineum and help lengthen the pelvic floor. Hold a supported squat (using a chair or countertop for balance) for 20 to 30 seconds at a time, focusing on letting the pelvic floor release rather than engage. This is essentially the opposite of a Kegel: you’re learning to let go, not tighten.
Perineal bulges are a more targeted exercise reserved for the last three weeks of pregnancy. Sit on a small towel placed lengthwise from front to back. Gently press your perineal area against the towel and think about moving your sit bones apart while moving your tailbone away from your pubic bone. The goal is to feel the perineum bulge outward and downward. If you’re unsure whether you’re doing it correctly, a mirror can help. You want to see the tissue moving out and down, not up and in (which would be a Kegel). Don’t practice these frequently, as overdoing it can strain the pelvic floor.
What Your Birth Team Can Do During Labor
Some of the most effective perineal protection happens during labor itself, particularly during the pushing stage when your baby’s head is crowning.
Warm compresses applied to the perineum during the second stage of labor are one of the best-studied interventions. A warm, moist pad placed against the perineum increases blood flow to the area, improves tissue elasticity, and relaxes the surrounding muscles. In clinical trials, women who received warm compresses had fewer second and third degree tears and reported less pain during pushing. The warmth also helps manage the intense stinging sensation of crowning that midwives often call the “ring of fire.” Both mothers and birth attendants consistently rate warm compresses as highly acceptable and comforting.
You can include warm compresses in your birth plan or discuss them with your midwife or provider ahead of time. During labor, a sterile gauze pad soaked in warm water is placed against the perineum and applied continuously as the baby’s head descends. This is something your birth team handles, but knowing to request it puts you in a stronger position.
Balloon Training Devices
Inflatable devices designed to gradually stretch the vaginal opening before birth (the most well-known brand is the EpiNo) are available in some countries. The idea is to simulate the stretching of crowning over several weeks of practice. Research results are mixed. Some studies found that women who used the device were more likely to have an intact perineum after delivery (37% versus 26% in one trial), while two randomized controlled trials found no significant difference in episiotomy or tear rates. A large multicenter trial of over 650 women reported no protective effect on the anal sphincter but also no negative effect on pelvic floor function.
The devices are generally well tolerated, with minor side effects like mild bleeding (about 8% of users), pain (about 9%), and occasional uterine contractions (1.5%). One serious but isolated case of suspected air embolism has been reported. If you’re considering a device like this, the evidence isn’t strong enough to call it clearly effective, but it also doesn’t appear to cause harm for most users.
When to Skip Perineal Massage
Perineal massage is safe for most pregnancies, but there are situations where you should hold off. Active vaginal infections make the tissue vulnerable to irritation and can spread the infection. If you notice unusual vaginal discharge, increased pain, or any bleeding during massage, stop immediately. Women with placenta previa, placental abruption, severe preeclampsia, or other complications that may require a cesarean delivery don’t need perineal preparation for vaginal birth. If you’re unsure whether massage is appropriate for your situation, a quick conversation with your provider can clarify things.
Putting It All Together
A practical timeline looks like this: begin perineal massage at 34 to 35 weeks, three to four times per week for about five minutes each session. Add deep squats to your routine throughout the third trimester. In the final three weeks, you can incorporate perineal bulging exercises in the positions you plan to use during labor. When you write your birth plan, include a note requesting warm compresses during the pushing stage.
None of these methods guarantee you won’t tear, and minor first degree tears are common even with excellent preparation. But each technique improves tissue flexibility, and combining them gives you the best chance of a less painful delivery and an easier recovery.
