The Claim
In nulliparous women during the second stage of labor, spontaneous pushing in the lateral position increases the mean duration of the second stage by approximately 12 minutes compared to Valsalva pushing in the supine position, without increasing the risk of cesarean delivery or adverse fetal outcomes.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
When first-time moms push naturally while lying on their side during childbirth, it takes about 12 minutes longer than pushing while lying on their back with forced breath-holding—but it doesn’t make C-sections or baby problems more likely.
See the scientific wording
Spontaneous pushing in the lateral position during the second stage of labor in nulliparous women increases the mean duration of the second stage by approximately 12 minutes (76.3 vs. 64.6 minutes) compared to Valsalva pushing in the supine position, without increasing the risk of cesarean delivery or adverse fetal outcomes.
What the research says
1 studyWhen first-time moms push naturally while lying on their side instead of holding their breath and pushing lying on their back, labor takes about 12 minutes longer — but it’s easier on mom and just as safe for the baby.
