The short answer first
There is no specific position that has been shown to lead to higher pregnancy rates. What matters is that sperm enter the vagina and the timing falls within the fertile window.
Many recommendations for particular positions sound plausible but are not medically proven.
Why the question about position is so common
When trying for a baby, people want to avoid doing anything wrong. The idea that a certain position can improve the chances gives a sense of control in a situation that often feels uncertain.
Top guides and major health websites agree: the importance of position is often overestimated while other factors are underestimated.
What biologically really matters
Pregnancy occurs when a fertilisable egg and sufficiently motile sperm meet at the right time. The following points are most important for this.
- Ovulation and the fertile window
- Sperm quality and motility
- Regular ejaculation in the days before ovulation
- Unobstructed passage of sperm towards the womb
Position has little influence on these factors. Sperm are motile and reach the cervix regardless of position.
What role gravity plays — and what it doesn’t
A common myth is that gravity is decisive. Positions where the penis enters from above are therefore thought to be especially suitable.
Medically this is not supported. Sperm swim actively and do not rely on flowing up or down. Studies show no clear advantage for particular positions.
Staying lying down after sex: useful or myth?
Many advise staying lying down or elevating the pelvis after sex. There is also no strong evidence for this.
Lying down briefly can be relaxing, but it is not essential. What matters is not what happens after sex, but what happens earlier in the cycle.
When positions can indirectly matter
Even though the position itself has no direct effect on fertility, it can have indirect effects.
- If a position is pain‑free and comfortable, sex can happen more often
- Less stress can have a positive effect on the cycle
- Good arousal improves natural lubrication and the transport of sperm
In that sense, the best position is the one that feels comfortable for both partners.
Myths and facts about position and pregnancy
Many half‑truths circulate on this topic. A clear view helps to avoid unnecessary pressure.
- Myth: Certain positions greatly increase the chances. Fact: There is no scientific evidence for this.
- Myth: Without gravity it won’t work. Fact: Sperm move actively.
- Myth: You have to lie down for a long time after sex. Fact: This is not necessary.
- Myth: The more complicated the position, the better. Fact: Complex positions offer no advantage.
- Myth: Sex only on the day of ovulation is enough. Fact: The days before ovulation are just as important.
What is sensible instead
Those trying to conceive should focus on well‑supported factors.
- Know and use the fertile days
- Sex every one to two days during the fertile window
- Reduce pressure and performance anxiety
- Allow sufficient time and arousal
A factual overview of the fertile window is available from the NHS on getting pregnant and the CDC on fertility.
When medical evaluation becomes sensible
If pregnancy does not occur after a long period of regular sex, medical assessment can help. This is independent of sexual position.
Discussing the cycle, sperm quality and hormonal factors early is often more helpful than trying different positions.
Conclusion
Which position is best for conceiving? No particular one. Position does not determine success or failure.
Timing, relaxation and regularity are more important. Letting go of myths reduces pressure and often creates better conditions.
