Trying to Conceive: Does Elevating Your Hips After Sex Actually Help?
If you’re trying to conceive, you’ve probably encountered the advice to lie with your hips elevated after sex to help sperm travel toward the egg. It’s one of those pieces of advice that gets passed around confidently without much interrogation of the underlying evidence. Here’s an honest look at what we actually know — and why a positioning wedge makes this as easy as possible if you want to give it a try.
What the Research Says
The research on hip elevation post-sex and conception rates is limited and mixed. The premise — that gravity assists sperm movement if the cervix is elevated above the vaginal opening — has some theoretical basis, but sperm are remarkably capable swimmers. Healthy sperm can reach the fallopian tubes within minutes of ejaculation regardless of body position. The cervix also retains sperm in cervical mucus following ejaculation, which acts as a reservoir regardless of gravity.
A 2009 Dutch study found that lying supine for 15 minutes after intrauterine insemination improved pregnancy rates. This has been extrapolated to recommend lying still after natural intercourse, sometimes with hips elevated. The extrapolation is reasonable but unproven — and most fertility specialists consider position after sex to be a minor factor at best.

Why Couples Do It Anyway (And Why That’s Fine)
The honest position is: it probably doesn’t hurt, and if it gives couples a sense of agency during a process that often feels out of their control, there’s real psychological value in that. Trying to conceive can be stressful and waiting-focused; having a concrete action to take after sex — even one whose evidence base is weak — is something many couples find helpful.
A positioning wedge makes the 15-minute post-sex elevation protocol significantly more comfortable than stacking regular pillows or trying to maintain a specific position. It holds the hips at a consistent angle without effort. If you’re going to do it, doing it comfortably is worthwhile.
The GloryHoleToGo wedge holds its angle without shifting — useful for the sustained post-sex position that TTC couples commonly want to maintain. See it on Amazon.
Positions During Sex for Conception
The same lack of strong evidence applies to specific sex positions during intercourse for conception purposes. Positions that allow deeper penetration — which places semen closer to the cervix — have theoretical advantages, and a sex wedge under the receiving partner’s hips in missionary genuinely does increase penetration depth and directness of contact with the cervical area. Whether this translates to improved conception rates hasn’t been rigorously studied, but the mechanical reasoning is sound.
Most fertility specialists suggest that the most important factor in conception is the timing of intercourse relative to ovulation — not position during or after. That said, positions that feel physically comfortable and allow couples to maintain regular intercourse without strain are beneficial for the sustained effort that TTC often requires.

Frequently Asked Questions
How long should I keep hips elevated after sex when TTC?
The commonly cited recommendation is 10–15 minutes. This is based on the IUI research extrapolated to natural intercourse. There’s no evidence that longer duration helps further — and the most important factor remains timing with ovulation.
What angle should the hips be elevated for TTC?
No specific angle has been studied. A standard sex wedge (7–9 inches at the tallest point) creates a meaningful elevation without being extreme. Comfort for sustained lying is also a factor — a position that can’t be held for 15 minutes is less useful.
Does body position during sex affect where sperm is deposited?
Penetration depth does affect proximity to the cervix. Positions that allow deeper penetration — which a wedge under the hips in missionary facilitates — place semen closer to the cervix at the point of ejaculation. Whether this meaningfully affects conception rates isn’t established.
Should I avoid going to the bathroom for 15 minutes after sex when TTC?
Most fertility guidance suggests waiting at least 10 minutes before getting up. Urinating after sex is important for UTI prevention but can wait briefly. Do not hold off if you have any discomfort — a UTI would be far more disruptive to TTC efforts than immediate urination.
Is the sex wedge safe to use during early pregnancy?
Yes — the wedge under the hips is safe in early pregnancy for most people. As pregnancy progresses, back-lying positions become less recommended, and side-lying with the wedge between knees or under the belly becomes more appropriate. Discuss with your provider at each stage.
