Top 5 Sex Positions to Conceive and How to Maximise Your Fertility

The best sex positions to conceive are those that allow deep penetration, placing sperm as close to the cervix as possible and shortening the distance it needs to travel to reach the fallopian tubes. While no specific position has been scientifically proven to guarantee pregnancy, fertility experts agree that positions enabling deeper penetration may give sperm a slight advantage. The NHS recommends having sex every 2 to 3 days throughout your cycle without worrying too much about timing or technique, but many couples trying to conceive find that combining ovulation awareness with the right sex positions to conceive gives them greater confidence and control over the process.

Does Sexual Position Really Affect Your Chances of Conceiving?

There is no large-scale clinical study proving that one sexual position is more effective than another for conception. As long as sperm is ejaculated into the vagina, it can travel through the cervix, into the uterus and along the fallopian tubes to meet the egg. However, positions that allow deeper penetration deposit sperm closer to the cervix, which may reduce the distance sperm needs to swim. This is one reason why sex positions to conceive with deep penetration are so widely recommended by fertility advisors and midwives.

What matters most is timing. You are most fertile during a window of roughly 6 days per cycle — the 5 days before ovulation and the day of ovulation itself. An egg survives only 12 to 24 hours after release, while sperm can live inside the body for up to 5 days. The NHS advises trying to have sex around the time of ovulation, which usually occurs 12 to 16 days before your next period. If you combine this timing with sex positions to conceive that maximise penetration depth, you are giving yourself the best possible chance.

What Are the Best Sex Positions to Conceive?

Rear entry (doggy style)

Rear entry is one of the most frequently recommended sex positions to conceive. You kneel on all fours while your partner enters from behind. This position allows deep penetration and deposits sperm close to the cervix. It is also considered particularly beneficial for women with a tilted uterus (retroflexed uterus), where the womb tilts toward the back of the pelvis rather than the front. Around 20% of women have a retroverted uterus, and rear entry can help align the cervix more favourably for sperm entry.

Modified rear entry (downward doggy)

A more comfortable variation of the standard rear entry. Rest your weight on your forearms rather than your hands, lowering your upper body so your hips are higher than your head. This tilt angles the pelvis upward, bringing the cervix closer to where sperm is deposited. Many fertility guides list this among the top sex positions to conceive because it combines deep penetration with a natural gravity-assisted angle.

Missionary with elevated hips

The classic missionary position — partner on top, face to face — is one of the simplest sex positions to conceive. To improve its effectiveness, place a pillow under your hips to tilt your pelvis upward. This keeps sperm pooled near the cervix after ejaculation and takes advantage of gravity. After sex, staying in this position for 10 to 15 minutes may further help sperm travel in the right direction, although the scientific evidence for this is limited.

Legs over shoulders (snail position)

You lie flat on your back and raise your legs so your feet rest on your partner’s shoulders. Your partner kneels and enters from the front. This position lifts your hips and allows very deep penetration, placing sperm directly against the cervix. It also naturally tilts the pelvis, making it easier for sperm to travel upward. If flexibility allows, this is one of the most effective sex positions to conceive for front-facing penetration.

Wheelbarrow

Your partner holds your legs while you support your upper body on your hands or forearms. Your hips are tilted upward and pressed against your partner, allowing deep penetration with a natural gap between your bodies. This position works best for couples of similar height and requires some upper-body strength, but it provides excellent cervical access.

How Can You Track Ovulation to Time Sex Positions to Conceive?

Knowing when you ovulate is at least as important as the position you choose. There are three reliable methods. The calendar method works if your cycle is regular: count from the first day of your period to the day before your next one. If your cycle is 28 days, you will ovulate around day 14. If it is 30 days, ovulation falls around day 16. Track this for 3 to 4 months to identify your personal pattern.

You can also monitor your basal body temperature, which rises by about 0.2°C after ovulation. Charting this over several months reveals your ovulation window. The most precise method is an ovulation predictor kit, available at any pharmacy. These detect the surge in luteinising hormone that occurs 24 to 36 hours before ovulation, giving you a clear signal to time intercourse. According to Fertility Network UK, a woman can conceive from intercourse occurring up to 5 days before and up to 2 days after ovulation — a fertile window of roughly one week.

What Else Can You Do to Boost Your Chances?

Beyond choosing the right sex positions to conceive and timing intercourse around ovulation, lifestyle factors make a real difference. The NHS recommends taking 400 micrograms of folic acid daily when trying to conceive, maintaining a healthy weight, reducing alcohol intake and stopping smoking. Your partner should also avoid smoking and excessive alcohol, as both reduce sperm count and motility.

Aim for sex every 2 to 3 days throughout your cycle rather than saving it all for ovulation day. This ensures a fresh supply of sperm is always available. After sex, lying on your back with your hips slightly elevated for 10 to 15 minutes may help, though evidence is anecdotal. Avoid using lubricants that are not fertility-friendly, as standard products can impair sperm movement. If you have been trying for 12 months without success (or 6 months if you are over 35), speak to your GP for further advice and possible referral to a fertility specialist.

For women who are using home insemination with donor sperm rather than natural intercourse, the principle of positioning still applies: lying on your back with elevated hips after insemination allows gravity to assist sperm movement. On CoParents.co.uk, a co-parenting and sperm donation platform with over 150,000 users since 2008, you can find donors and access resources for every path to conception.

Frequently Asked Questions

Do sex positions to conceive really make a difference?

There is no definitive scientific proof that one position guarantees conception over another. However, sex positions to conceive that allow deep penetration place sperm closer to the cervix, which may give it a slight advantage. The most important factor is timing intercourse around ovulation and having sex regularly throughout your cycle.

Should I stay lying down after sex to help conception?

Many fertility experts suggest lying on your back with your hips slightly elevated for 10 to 15 minutes after intercourse. While this has not been proven in clinical trials, it is unlikely to do any harm and may help keep sperm near the cervix. Avoid jumping up immediately after sex if you are actively trying to conceive.

How often should we have sex when trying to conceive?

The NHS recommends having sex every 2 to 3 days without using contraception. This is more effective than trying to time intercourse to a single ovulation day, because sperm can survive in the body for up to 5 days. Regular sex throughout the cycle ensures sperm is always available when the egg is released.

Are there positions that are better for women with a tilted uterus?

Yes. Rear entry positions (such as doggy style and its variations) are often recommended for women with a retroverted or tilted uterus. These are among the most commonly recommended sex positions to conceive for women with this condition. If you are unsure whether you have a tilted uterus, your GP or fertility specialist can confirm this during a routine examination.
