Most people who give birth vaginally will experience some degree of tearing, but several techniques before and during labor can meaningfully reduce the severity. The most effective strategies combine preparation in the final weeks of pregnancy with specific approaches during delivery itself. Here’s what the evidence supports.
What Perineal Tears Actually Are
Tearing happens in the perineum, the stretch of tissue between the vaginal opening and the anus. Tears are graded by depth. First-degree tears affect only the skin and typically heal on their own without stitches. Second-degree tears go deeper into the muscle of the perineum and usually need stitches. Third- and fourth-degree tears, which occur in about 4% or fewer vaginal deliveries, extend into the muscle that controls the anus. These more severe tears require surgical repair and a longer recovery.
Understanding the grading matters because different prevention strategies target different severities. Some techniques reduce overall tearing, while others specifically lower the risk of those deeper, more consequential injuries.
Perineal Massage Before Labor
Starting at 34 weeks of pregnancy, massaging the perineum three to four times a week for three to five minutes each session helps the tissue stretch more easily during delivery. Even doing it once or twice a week from 34 weeks may offer some benefit. The goal is to gradually increase the tissue’s flexibility so it can accommodate the baby’s head with less trauma.
To do it, use a natural oil (like olive or coconut oil) on clean thumbs, insert them about an inch into the vagina, and press downward toward the rectum while gently sweeping side to side. You’ll feel a stretching or mild burning sensation, which is normal. Over several weeks, the tissue becomes more pliable and the sensation less intense. A partner can help if reaching is uncomfortable in late pregnancy.
Warm Compresses During Delivery
Applying a warm cloth to the perineum during the pushing stage is one of the most well-supported techniques for preventing severe tears. A Cochrane review found that warm compresses likely cut the risk of third- or fourth-degree tears by roughly half. The effect on milder second-degree tears was less clear, but warm compresses also significantly reduced perineal pain during delivery.
This is something to discuss with your birth team in advance. A midwife or nurse applies a warm, damp cloth to the perineum as the baby’s head crowns, maintaining gentle pressure. It’s simple, low-cost, and carries no known risks. If reducing severe tears is a priority for you, this is worth requesting in your birth plan.
Birthing Positions That Help
The position you’re in when the baby is delivered affects how much strain falls on the perineum. Lying flat on your back (supine), sitting upright, or being in the lithotomy position (on your back with legs in stirrups) all limit how much your pelvis can flex and open, concentrating pressure on the perineum. Research links these positions with higher rates of second-degree tears.
Positions that allow more movement in the sacrum, the bone at the base of your spine, tend to distribute pressure more evenly. Kneeling, side-lying (lateral), and hands-and-knees are commonly recommended alternatives. There’s one trade-off worth knowing: a systematic review found that upright positions were associated with fewer episiotomies but a slightly higher incidence of tears that needed stitching compared to lying on your side. The side-lying position appears to offer a good balance of both fewer interventions and less perineal trauma.
If your labor allows for it, staying mobile and changing positions based on comfort can help you find what works. Hospital settings sometimes default to on-your-back positioning for the provider’s convenience, so it’s worth discussing alternatives ahead of time.
Pushing Technique and Timing
How you push matters, though the evidence is more nuanced than many birth preparation classes suggest. The idea of “breathing the baby down” or pushing gently and slowly during crowning has intuitive appeal: less force on the perineum should mean less tearing. One large randomized trial compared moderate, intermittent pushing to intensive pushing (three pushes per contraction without rest). The intensive group finished faster (26 versus 32 minutes of active pushing) with no increase in perineal trauma.
What does seem to help is controlled delivery of the baby’s head at the moment of crowning. Slowing down during those final moments, following your birth attendant’s guidance to ease off or give small pushes, allows the tissue to stretch gradually rather than tearing under sudden force. This is one area where communication with your provider during labor makes a real difference.
What Your Provider Does During Delivery
Birth attendants use two main approaches as the baby’s head emerges. The “hands-on” technique involves actively flexing the baby’s head and supporting the perineum with a hand. The “hands-poised” approach means the provider keeps their hands ready but doesn’t actively touch the perineum or baby’s head unless needed.
A meta-analysis of nine randomized trials involving over 7,000 participants found no significant difference between the two techniques for severe tears. However, the hands-poised approach was associated with less perineal pain, fewer episiotomies, and a higher rate of completely intact perineums. It did not increase the risk of postpartum hemorrhage or prolong the second stage. For low-risk vaginal deliveries, the hands-poised technique appears to be a reasonable option worth discussing with your provider.
Episiotomy Is Not Prevention
For decades, episiotomy (a surgical cut to widen the vaginal opening) was performed routinely on the theory that a clean cut would heal better than a ragged tear. That theory didn’t hold up. The American College of Obstetricians and Gynecologists now recommends episiotomy only when absolutely necessary, such as when the baby is in distress and needs to be delivered quickly, or to prevent a larger tear that’s clearly about to happen. Routine episiotomy actually increases the risk of more severe injury.
If your provider suggests an episiotomy during labor, it’s reasonable to ask why. In an emergency, there may not be time for discussion, but in a planned birth setting you can clarify their general approach to episiotomy beforehand.
Risk Factors You Can’t Control
Some factors that increase tearing risk aren’t modifiable. The primary risk factors for severe tears are those associated with a difficult vaginal delivery, most notably forceps-assisted delivery. Vacuum-assisted delivery also raises the risk, though less than forceps. A larger baby, a first vaginal birth, and a prolonged pushing stage all contribute. Having had a previous tear doesn’t necessarily mean you’ll tear again, but it’s useful information for your birth team to have.
Knowing your risk factors helps you prioritize the strategies you can control. If you’re having your first baby or your baby is measuring large, the combination of antenatal perineal massage, warm compresses during delivery, and an optimal birthing position gives you the best chance of reducing the severity of any tear.
What About Lubricants During Delivery
Some birth attendants apply water-based lubricant or oil to the perineum during the pushing stage, and it seems like it would help. The evidence, however, is underwhelming. Studies found that lubricant use with or without massage during the second stage of labor does not reduce first- or second-degree tears compared to standard care. The effect on severe tears is unclear simply because they’re rare enough that the studies lacked the statistical power to detect a difference. Lubricant isn’t harmful, but it shouldn’t be relied on as a primary prevention strategy.
Putting It All Together
The most practical approach combines a few evidence-based steps. Start perineal massage at 34 weeks, aiming for at least three sessions per week. Include warm compresses and your preferred birthing position in your birth plan, and discuss these with your provider before labor begins. During delivery, follow your birth attendant’s guidance on pacing your pushes as the baby crowns. None of these strategies guarantees you won’t tear, but together they meaningfully reduce both the likelihood and severity of perineal injury.
