Best Sex Positions to Get Pregnant: What the Science Actually Says

If you are trying to conceive, you have probably heard every piece of advice from your mother, your best friend, and every pregnancy forum on the internet. One of the most persistent myths is that certain sex positions will dramatically increase your chances of getting pregnant. The truth is more nuanced, and understanding what the science actually says can save you stress and help you focus on what truly matters for conception.

“No scientific evidence shows that any specific sex position significantly increases conception rates. Sperm reach the cervix within seconds regardless of position. The most important factors for conception are timing (ovulation), sperm health, and regular sexual intercourse. However, positions that allow deeper penetration may deposit sperm closer to the cervix, which some research suggests may marginally help.” — Dr. James Chen, Board-Certified OB/GYN

Research from The Journal of Sexual Medicine (2021) found that position had minimal impact on conception rates, but couples who had sex every 1-2 days during the fertile window had the highest conception rates at 33% per cycle.

The Great Position Myth

Let us start with the big question: does the position you have sex in affect your chances of getting pregnant? The short answer is no, not in the way most people think. According to the American Society for Reproductive Medicine (ASRM), sperm are remarkably efficient travelers. Once deposited near the cervix, sperm can reach the fallopian tubes within minutes, regardless of the position used during intercourse. The cervix acts as a reservoir, and sperm do not need gravity or a specific angle to make their way to the egg.

This means that the popular belief that missionary position is superior because it allows deeper penetration and deposits sperm closer to the cervix is only partially accurate. While it is true that certain positions place semen closer to the cervix, the difference is negligible because sperm begin swimming immediately upon ejaculation. The woman’s body does the work of transporting sperm, not gravity.

What the Research Shows

Studies on conception and sexual positions have consistently shown that position is not a significant factor in fertility. A study published in the journal Fertility and Sterility found no correlation between sexual position and pregnancy rates. The researchers concluded that the timing of intercourse relative to ovulation was far more important than the position used.

The ASRM emphasizes that couples should focus on having regular intercourse during the fertile window rather than worrying about which position will give them the best chance. The fertile window is the five days leading up to ovulation and the day of ovulation itself. This is when the egg is available for fertilization, and having sex during this time dramatically increases the odds of conception.

Timing Is Everything

If position does not matter much, what does? Timing. Understanding your menstrual cycle and identifying your fertile window is the single most important factor in getting pregnant. Ovulation typically occurs around day 14 of a 28-day cycle, but this can vary significantly between women. Using ovulation predictor kits, tracking basal body temperature, and monitoring cervical mucus changes can help you pinpoint your most fertile days.

Having intercourse every one to two days during the fertile window ensures that sperm are present when the egg is released. Sperm can survive in the reproductive tract for up to five days, so having sex in the days leading up to ovulation is just as important as having sex on the day of ovulation itself.

Sperm Health Matters More Than Position

Rather than focusing on which position to use, couples trying to conceive should pay more attention to factors that affect sperm quality. The health of sperm plays a crucial role in conception. Here are some evidence-based tips for optimizing sperm health:

• Maintain a healthy weight: Both obesity and being underweight can negatively affect sperm production and quality.
• Avoid excessive heat: Hot tubs, saunas, and even prolonged laptop use on the lap can raise scrotal temperature and impair sperm production.
• Limit alcohol and quit smoking: Both alcohol and tobacco have been shown to reduce sperm count and motility.
• Take antioxidants: Vitamins C and E, selenium, and zinc have been shown to support sperm health.
• Manage stress: Chronic stress can affect hormone levels and reduce sperm quality.
• Avoid anabolic steroids: These can suppress sperm production significantly.

For women, maintaining a healthy lifestyle, managing stress, and ensuring adequate intake of folic acid and prenatal vitamins are important for fertility and a healthy pregnancy.

The Legs-Up Myth

One of the most enduring myths about conception is that lying with your legs up after sex will help sperm reach the egg. There is no scientific evidence to support this claim. In fact, studies have shown that sperm reach the cervix within seconds of ejaculation, regardless of body position. The cervix is only a few inches from the vaginal opening, and sperm are powerful swimmers. Lying down for a few minutes after sex may feel relaxing, but it does not increase the chances of conception.

Some couples find comfort in this ritual, and if it reduces stress, it is perfectly fine to continue. However, it should not be seen as a necessary step for getting pregnant. The pressure to perform this “trick” can actually add unnecessary stress, which is counterproductive for fertility.

Positions That Feel Intimate During the Fertile Window

While the scientific evidence does not support the idea that certain positions are better for conception, there are positions that can feel more intimate and enjoyable during the fertile window. When you are focused on timing and trying to conceive, it is easy for sex to feel like a chore. Choosing positions that promote closeness and pleasure can help maintain intimacy and reduce the pressure.

1. Missionary Position

The missionary position allows for face-to-face intimacy and eye contact, which can make the experience feel more connected. It also allows for deep penetration, which some couples find satisfying. While the depth of penetration does not significantly affect conception, the closeness and emotional connection can reduce stress and make the experience more enjoyable.

2. Spooning (Side-Lying)

Spooning is a gentle, intimate position where both partners lie on their sides, with the penetrating partner behind. This position allows for shallow to moderate penetration and is very relaxed. It is a great option for couples who want to feel close without the intensity of deeper positions. It is also comfortable for the receiving partner and can be sustained for longer periods without fatigue.

3. Cowgirl (Partner on Top)

When the receiving partner is on top, they have full control over the depth and pace of penetration. This can be empowering and allow for more pleasure and comfort. It also allows the receiving partner to angle their body in a way that feels good, which can increase the likelihood of orgasm. Some research suggests that female orgasm may help transport sperm toward the egg, though this is not conclusively proven. Regardless, orgasm increases uterine contractions that may assist sperm movement.

Focus on Connection, Not Perfection

Trying to conceive can be stressful and emotionally taxing. For more on sex positions during pregnancy, see our sex positions during pregnancy guide. It is important to remember that sex is not just about making a baby; it is also about connection, pleasure, and intimacy with your partner. Focusing too rigidly on positions, timing, and techniques can take the joy out of the experience. Instead, focus on regular intimacy, open communication, and maintaining a healthy lifestyle.

If you have been trying to conceive for more than a year without success (or six months if you are over 35), it is a good idea to consult with a fertility specialist. There may be underlying factors that need to be addressed, and a healthcare provider can offer personalized guidance and support.

Conclusion

The best sex position for getting pregnant is the one that feels good for both partners and allows you to have regular, enjoyable intercourse during your fertile window. The science is clear: timing and sperm health matter far more than position. Let go of the myths, focus on what you can control, and enjoy the journey of trying to conceive with your partner.

Frequently Asked Questions

Does the missionary position really help with conception?

While missionary allows for deeper penetration and may deposit sperm closer to the cervix, research shows this doesn’t significantly increase conception rates. Sperm reach the cervix within seconds regardless of position. However, missionary can feel more intimate and reduce stress, which indirectly supports fertility. The best position is the one that feels good and allows regular intercourse.

Should I lie down after sex to help sperm reach the egg?

There’s no scientific evidence that lying down after sex improves conception. Sperm reach the cervix within seconds of ejaculation, regardless of body position. The cervix acts as a reservoir, and sperm swim actively toward the fallopian tubes. If lying down feels relaxing and reduces stress, it’s fine to continue, but it’s not necessary for conception.

How often should we have sex during the fertile window?

Research suggests having sex every 1-2 days during the fertile window (the 5 days leading up to ovulation and the day of ovulation) provides the best chances of conception. This ensures sperm are present when the egg is released. Having sex daily is also fine if both partners are comfortable. The key is regular intercourse during your most fertile days.

Can female orgasm help with conception?

Some research suggests female orgasm may help transport sperm toward the egg through uterine contractions, but this is not conclusively proven. Orgasm increases blood flow to the uterus and creates contractions that might assist sperm movement. However, conception can occur without orgasm. Focus on pleasure and connection rather than using orgasm as a conception tool.

Does lubricant affect sperm health?

Some lubricants can harm sperm motility and viability. Avoid lubricants with spermicides, nonoxynol-9, or oil-based ingredients. Use fertility-friendly lubricants specifically designed for conception, like Pre-Seed or natural options like coconut oil. Even water-based lubricants can affect sperm, so consider using them sparingly or choosing products tested for sperm compatibility.

When should we see a fertility specialist?

Consult a fertility specialist if you’ve been trying to conceive for more than a year without success (or six months if you’re over 35). Also seek help if you have irregular periods, known fertility issues, a history of pelvic inflammatory disease, or if your partner has a history of testicular problems. Early evaluation can identify treatable conditions and reduce unnecessary stress.
