Vaginal tearing during childbirth is common, but several techniques before and during labor can meaningfully reduce your risk, especially of the more severe tears. About 9 in 10 first-time mothers experience some degree of tearing, so while it can’t always be avoided entirely, the goal is to minimize the severity. The strategies with the strongest evidence include perineal massage in late pregnancy, warm compresses during delivery, and avoiding unnecessary interventions like routine episiotomy.
What Tearing Actually Involves
Tears are classified into four degrees based on how deep they go. First-degree tears are the mildest, involving only the skin of the perineum (the area between the vaginal opening and the rectum) or around the urethra. These often heal on their own without stitches. Second-degree tears go deeper into the muscle of the perineum and may extend into the vagina. These are the most common type and typically require stitches.
Third-degree tears reach into the muscle that surrounds the anus (the anal sphincter), and fourth-degree tears go all the way through that muscle into the lining of the rectum. These severe tears are less common but take significantly longer to heal and carry a higher risk of complications like incontinence. Most prevention strategies focus specifically on reducing the chances of these third- and fourth-degree injuries.
Who Has a Higher Risk
Certain factors make tearing more likely, and knowing them helps you understand which prevention strategies matter most for your situation. Your risk is higher if this is your first vaginal delivery, if your baby weighs more than 8 pounds, or if your baby is facing up (sunny-side up) instead of face down during delivery. A prolonged pushing stage, the use of forceps or vacuum assistance, and having an epidural also increase the likelihood of tearing.
Some of these factors are outside your control. But several of the most effective prevention techniques work regardless of your risk profile.
Perineal Massage Before Birth
Perineal massage is one of the most well-studied prevention techniques, and it’s something you can do at home. The idea is straightforward: by gently stretching the tissue of the perineum in the weeks before birth, you help it become more flexible and better able to stretch around your baby’s head during delivery.
The Royal Women’s Hospital recommends starting perineal massage at 34 weeks of pregnancy, doing it every one to two days for five to ten minutes per session. The technique involves inserting one or two clean, lubricated thumbs about an inch into the vagina and pressing downward toward the rectum, then sweeping in a U-shaped motion while applying steady pressure. You should feel a stretching sensation, but it shouldn’t be painful.
The benefit is most pronounced for first-time mothers. If you’ve had a previous vaginal delivery, your tissues have already stretched significantly, so the additional benefit of massage is smaller, though not zero.
Perineal Stretching Devices
Balloon-type devices designed to gradually stretch the perineum before birth have gained popularity. The most studied is a device called the Epi-No, which is used from 34 weeks of pregnancy under guidance from a healthcare provider. One study from the International Continence Society found striking results: 83.8% of women who used the device with professional supervision experienced no tearing or only a first-degree tear, compared to just 34.4% in the group that didn’t use it. Women who didn’t use the device had nearly ten times the odds of a second- or third-degree tear or episiotomy.
There’s an important caveat. The evidence suggests the device works best, and possibly only, when used under specialized supervision. Studies where women used it without guidance have shown much less clear results. If you’re interested, work with a pelvic floor physiotherapist who can show you the correct technique and monitor your progress.
Warm Compresses During Delivery
One of the simplest and most effective interventions happens during labor itself. When a healthcare provider holds a warm, damp cloth against your perineum as the baby’s head is crowning, it relaxes the tissue and increases blood flow to the area. A Cochrane review of four studies involving nearly 1,800 women found that warm compresses cut the risk of third- and fourth-degree tears by 54%. That’s a substantial reduction in the most serious injuries, achieved with nothing more than a warm cloth.
The compress didn’t significantly change the rate of minor tears or the overall likelihood of needing stitches. Its primary benefit is in preventing the deep, severe tears that cause the most lasting problems. This is worth discussing in your birth plan, since it requires your delivery team to actively apply the compress during the pushing stage.
Pushing Techniques and Timing
How you push can influence tearing. There are two main approaches: directed pushing, where a coach tells you when and how hard to push (often called “purple pushing” or Valsalva pushing), and spontaneous pushing, where you follow your body’s natural urges. Directed pushing has been associated with increased use of episiotomy and a longer second stage of labor in some studies, though the evidence on severe tears specifically is mixed.
What does seem to help is slowing down during crowning. When your baby’s head is at its widest point stretching the perineal tissue, controlled, gentle pushing (or even pausing briefly) gives the tissue more time to stretch gradually rather than tearing under sudden pressure. Your midwife or doctor may ask you to stop pushing and pant or blow through a contraction at this stage. This “hands-on” approach, where the provider supports the perineum and controls the speed of the baby’s head delivery, is one of the most practical ways to reduce tearing in the moment.
Birthing Positions
The position you deliver in affects how much pressure is placed on the perineum. Lying flat on your back with your legs in stirrups (the lithotomy position) concentrates force on the perineum and is associated with higher tearing rates. Upright and gravity-neutral positions tend to distribute pressure more evenly.
Side-lying is often cited as one of the gentler positions for the perineum, as it reduces the stretch on the tissue. Hands-and-knees (all fours) is another option that takes direct pressure off the perineal area. Squatting opens the pelvis wide, which can speed delivery but may increase strain on the perineum for some women. There’s no single “best” position for every body, so being able to move and change positions during labor, rather than being confined to one, gives you the most flexibility to find what works.
Why Routine Episiotomy Does More Harm
An episiotomy is a surgical cut made in the perineum to widen the vaginal opening during delivery. For decades, it was performed routinely on the theory that a clean cut would heal better than a ragged tear. That theory turned out to be wrong. The American College of Obstetricians and Gynecologists now recommends against routine episiotomy, finding that it does not reduce the risk of severe tearing and actually increases the risk of posterior perineal trauma, the need for suturing, and healing complications.
When researchers compared routine episiotomy to restricted use, 72.7% of women in the routine group underwent the procedure compared to 27.6% in the restricted group. The restricted group had significantly better outcomes across the board. Episiotomy still has a role in specific emergency situations, like when a baby needs to be delivered quickly, but it should not be a default part of delivery. If your provider routinely performs episiotomies, that’s worth a conversation.
What About Water Birth?
Laboring in warm water is popular in part because of claims that it reduces tearing. However, the evidence doesn’t support this. A systematic review of three clinical trials concluded that immersion in water during labor is not effective in preventing perineal tears. While one small study found no third-degree tears among water births, another found a higher relative risk of third-degree tears in the water group. The results are inconsistent, and water birth has other potential benefits (like pain relief), but reducing tearing doesn’t appear to be one of them.
Putting It All Together
The most effective approach combines preparation before labor with techniques during delivery. Starting at 34 weeks, practice perineal massage every one to two days for five to ten minutes. If you have access to a pelvic floor physiotherapist, consider working with them on perineal stretching, either manually or with a device. During labor, include warm compresses and a slow, controlled delivery of the baby’s head in your birth plan. Choose an upright or side-lying position if you can, and let your provider know you’d prefer spontaneous pushing over coached, forceful pushing. Avoid routine episiotomy by discussing your preferences with your care team well before your due date.
No combination of techniques guarantees you won’t tear. But each one shifts the odds, and together they meaningfully reduce both the likelihood and severity of injury.
