Most couples who are trying to conceive will succeed within a year, and the single biggest factor within your control is timing sex to your fertile window. Sperm can survive in the reproductive tract for up to five days, while an egg lives roughly 12 to 24 hours after ovulation. That means the days just before ovulation matter more than the day itself. Beyond timing, the steps that genuinely help are the unglamorous ones: treat health conditions, stop smoking, limit alcohol, reach a healthy weight, and take a prenatal vitamin with folic acid. Many popular fertility tips have little evidence behind them, and this article separates what works from what does not.
How To Increase Chances Of Getting Pregnant By Timing Sex
Timing intercourse to the days before ovulation is the most reliable self-directed step a couple can take. The fertile window is generally the five days before ovulation plus the day of ovulation itself. Conception is most likely from sex in the two to three days leading up to ovulation.
The biology explains why. After ejaculation, sperm can remain viable in the cervix and fallopian tubes for several days. The egg, once released, is fertilizable for only about a day. Sex after ovulation has passed is very unlikely to result in pregnancy in that cycle.
Having sex every one to two days during the fertile window covers the window without the strain of daily performance. There is no good evidence that abstaining for many days beforehand improves sperm quality in a way that raises pregnancy rates. In fact, long gaps between ejaculations can reduce sperm motility in some men. For most couples, regular sex through the window is the practical approach.
Tracking ovulation helps you identify the window, but it is not a precise science at home. Ovulation predictor kits detect the surge in luteinizing hormone (LH) that precedes ovulation, usually by about 24 to 36 hours. Basal body temperature rises after ovulation, which confirms that ovulation happened but cannot predict it in advance. Cervical mucus becomes clearer and stretchier near ovulation, which is a useful secondary sign. Apps that estimate ovulation from cycle length are only rough guides, especially if your cycles are irregular.
If your cycles are irregular, ovulation tracking becomes harder and less reliable. That is a reasonable point to talk to a clinician rather than rely on app predictions.
What Health Changes Actually Improve Fertility?
Several lifestyle and health factors have solid evidence behind them for both partners. These are not quick fixes, but they are the changes most likely to matter.
- Stop smoking. Smoking is linked to reduced fertility in both men and women, and it affects sperm quality and egg health. Stopping is one of the most meaningful changes either partner can make.
- Limit alcohol. Heavy drinking is associated with reduced fertility. Guidance for people trying to conceive generally advises avoiding or strictly limiting alcohol, especially for women, since there is no established safe level during pregnancy.
- Reach a healthy weight. Both very low and very high body weight can disrupt ovulation in women and affect sperm production in men. Weight that falls in a healthy range is associated with better fertility outcomes.
- Take folic acid. A daily prenatal vitamin containing folic acid is widely recommended before conception to reduce the risk of neural tube defects. Standard guidance is 400 micrograms daily for most women, with higher doses for some women with specific risk factors as directed by a clinician.
- Manage chronic conditions. Poorly controlled diabetes, thyroid disease, and high blood pressure can affect fertility and pregnancy. Getting these under control before conception matters.
- Review medications. Some medications affect fertility or are not recommended in pregnancy. A clinician or pharmacist can review what you take.
For men, heat exposure is worth a mention. The testes sit outside the body because sperm production works best at slightly below core body temperature. Frequent prolonged heat exposure — such as regular hot tub use or laptop placement on the lap for long periods — has been studied for effects on sperm, though the evidence on whether it meaningfully changes pregnancy rates is limited. It is reasonable to avoid prolonged heat to the groin, but no strong evidence confirms it improves conception.
Does Diet And Supplements Help You Get Pregnant?
Diet affects fertility mainly through its effect on weight, blood sugar, and overall health rather than through any single “fertility food.” No food or supplement has been shown to reliably increase pregnancy rates in otherwise healthy couples.
A balanced diet rich in vegetables, whole grains, fruits, legumes, and healthy fats, with limited processed foods and added sugars, supports metabolic health and a healthy weight. That is the realistic benefit. Specific claims about particular foods boosting fertility are largely marketing.
On supplements, the picture is mixed and often oversold:
- Folic acid has strong evidence for reducing neural tube defects and is the one supplement with clear preconception guidance.
- Vitamin D is often checked and corrected if low, but there is no strong evidence that supplementing in people with normal levels improves fertility.
- Antioxidants and “fertility blends” sold for sperm or egg quality have limited and inconsistent evidence. No large human trials confirm they increase pregnancy rates.
- Herbal and “detox” products marketed for fertility have no reliable evidence and some can interact with medications. Treat these with caution.
If you are considering any supplement beyond a standard prenatal vitamin, discuss it with a clinician. Doses and safety during conception and pregnancy are not established for most products, and some are actively risky.
How Does Age Affect Getting Pregnant?
Age is the strongest single factor affecting fertility, and it declines gradually for women across their thirties and more steeply after the mid-thirties. This is driven mainly by the number and quality of eggs, which decline over time. Men’s fertility also declines with age, though more gradually.
These are population patterns, not predictions about any individual. Many women conceive in their late thirties and early forties, and many do not. The practical implication is about how long to try before seeking help, not about giving up.
Because fertility declines with age, the timing of when to see a clinician depends partly on age. General guidance is to seek evaluation after about a year of trying for women under 35, and after about six months for women 35 and older. Women with irregular cycles, known conditions affecting fertility, or other concerns should seek advice sooner rather than waiting. These timelines are widely used in clinical practice, but your own situation may warrant a different approach.
When Should You See A Fertility Specialist?
Seek evaluation sooner if you have a known condition or symptom that affects fertility, rather than waiting out the usual timelines. Conditions like endometriosis, polycystic ovary syndrome (PCOS), thyroid disorders, or a history of pelvic infection can affect fertility and are worth discussing early.
For men, signs such as previous testicular injury, surgery, or known sperm problems warrant earlier evaluation. Male factors contribute to a substantial share of infertility cases, so both partners should be evaluated, not just the woman. This is a point many couples miss.
Red flags that justify earlier assessment include very irregular or absent periods, severe pelvic pain with periods, and a history of multiple miscarriages. If you have been trying for the timelines above without success, a fertility evaluation is appropriate. Testing is straightforward and can identify treatable causes.
Fertility treatment is a large topic with its own evidence base. What matters here is that early evaluation does not commit you to any particular treatment. It gives you information.
What Fertility Tips Do Not Actually Work?
Several widely shared fertility tips have little or no evidence behind them. It helps to know which ones to stop worrying about.
- Specific sex positions. No evidence shows that any position improves conception. Sperm reach the cervix regardless of position.
- Lying with legs raised after sex. There is no good evidence this improves pregnancy rates. Sperm are motile and move into the cervix quickly.
- Avoiding certain foods entirely. Unless you have a specific allergy or medical reason, cutting out food groups does not improve fertility and can harm nutrition.
- “Detox” cleanses. No evidence supports fertility detoxes, and some products are unsafe.
- Timing sex only on the day of ovulation. This misses the more fertile days before ovulation.
- Strict dietary rules or extreme exercise. Over-exercising and severe calorie restriction can disrupt ovulation and reduce fertility.
One clarification worth knowing: “trying harder” by having sex many times a day does not improve odds and can reduce sperm concentration per ejaculation. Every one to two days through the fertile window is the sensible approach.
Stress is often blamed for infertility, and the relationship runs in both directions. Trying to conceive can be stressful, and stress may affect libido and cycle regularity, but there is no strong evidence that reducing stress alone raises pregnancy rates. Managing stress is good for you regardless, but it is not a fertility treatment.
What Should Both Partners Do Before Trying?
A preconception visit with a clinician is worthwhile for both partners. It is a chance to review medications, update vaccinations, screen for conditions that affect pregnancy, and discuss any concerns. It is not required, but it catches issues early.
For women, starting a prenatal vitamin with folic acid before conception is the step with the clearest evidence. For men, avoiding smoking, limiting alcohol, and maintaining a healthy weight are the priorities. Both partners benefit from regular physical activity, adequate sleep, and managing chronic conditions.
It also helps to set realistic expectations. Most couples conceive within a year of regular unprotected sex, but not all. If it takes longer, that is common and not a sign that something is wrong with you. The right response is evaluation, not self-blame.
Frequently Asked Questions
How often should we have sex to get pregnant?
Every one to two days during your fertile window, which is about the five days before ovulation plus the day of ovulation. Regular sex through this window gives the best chance without reducing sperm quality.
Can certain positions help you get pregnant?
No. There is no evidence that any sex position improves the chance of conception. Sperm reach the cervix regardless of position.
How long should we try before seeing a doctor?
About one year if the woman is under 35, and about six months if she is 35 or older. See a clinician sooner if you have irregular periods, known fertility conditions, or other concerns.
Does folic acid help you get pregnant?
Folic acid does not directly increase the chance of conception, but it reduces the risk of neural tube defects in a baby. Standard guidance is 400 micrograms daily before conception, with higher doses for some women as directed by a clinician.
