There’s no strong evidence to show that using a vibrator can induce labor. While a vibrator could cause you to orgasm, and an orgasm releases oxytocin, which can help stimulate contractions, it’s unlikely to be enough to start labor on its own. It’s generally safe to use a vibrator if it’s something you’re comfortable with, but it’s always best to discuss it with your healthcare provider first to ensure it’s appropriate for your situation.
Your provider may tell you to avoid using a vibrator if you have certain pregnancy complications, like placenta previa, risk of preterm labor, or cervical insufficiency (where the cervix begins to open too early). With these complications, any form of sexual activity that causes you to orgasm and have uterine contractions could potentially trigger preterm labor or bleeding.
Additionally, using a vibrator externally is typically safer than vaginal insertion. Inserting anything into your vagina during pregnancy can cause irritation or introduce bacteria, so it’s best to keep the vibrator outside of your vagina. And no matter what kind of vibrator you use, always make sure that it’s clean to avoid possible infections.
