The short answer first
There is no specific position that has been shown to increase pregnancy rates. What matters is that sperm enter the vagina and that intercourse occurs during the fertile window.
Many recommendations for particular positions sound plausible but are not supported by medical evidence.
Why the question about position is so common
When there is a desire for children, people want to avoid doing anything wrong. The idea that a certain position can increase chances gives a sense of control in a situation that often feels uncertain.
Top advice sources and major health portals agree: the role of position is overrated and other factors are underestimated.
What biologically really counts
Pregnancy occurs when a fertilisable egg and sufficiently motile sperm meet at the right time. The following points are especially important.
- Ovulation and the fertile window
- Sperm quality and motility
- Regular ejaculation in the days before ovulation
- Unobstructed passage of sperm toward the uterus
Position has little effect on these factors. Sperm are motile and reach the cervix regardless of position.
What role gravity plays — and what it does not
A common myth is that gravity is decisive. Positions where the man is on top are therefore often considered especially suitable.
Medically this is not supported. Sperm swim actively and do not rely on flowing upward or downward. Studies do not show a clear advantage for particular positions.
Staying lying down after sex: useful or myth?
Many recommend staying lying down after sex or elevating the pelvis. There is no strong evidence for this either.
Lying down briefly can be relaxing, but it is not necessary. What matters is not what happens after sex but what happens earlier in the cycle.
When positions can have an indirect role
Even though position itself has no direct effect on fertility, it can play an indirect role.
- If a position is pain-free and comfortable, sex may occur 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 getting pregnant
Many half-truths circulate on this topic. A clear view helps to avoid unnecessary pressure.
- Myth: Certain positions significantly increase chances. Fact: There is no scientific evidence for this.
- Myth: It does not work without gravity. Fact: Sperm move actively.
- Myth: You must lie down for a long time after sex. Fact: That is not necessary.
- Myth: The more complicated the position, the better. Fact: Complex positions provide no benefit.
- Myth: Sex only on the day of ovulation is enough. Fact: The fertile days before ovulation are just as important.
What is more useful instead
Those trying to conceive should focus on well-supported factors.
- Know and use the fertile days
- Have 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 can be found at the NHS on getting pregnant and at the CDC on fertility.
When medical evaluation becomes sensible
If pregnancy does not occur despite regular sex over an extended period, medical evaluation can help. This is independent of sexual position.
Discussing the cycle, sperm quality and hormonal factors early is often more helpful than further experiments with positions.
Conclusion
Which position is best for getting pregnant? 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.
