Getting pregnant comes down to a few core factors: timing sex correctly, keeping your body in good shape for conception, and making sure your partner’s sperm health is on track too. Most couples conceive within a year of trying, but there are specific, evidence-backed steps you can take to improve your chances each cycle.
Nail the Timing
Sperm can survive inside the body for up to five days, but a released egg lives for less than 24 hours. That means your fertile window is roughly six days long: the five days before ovulation plus the day of ovulation itself. The highest pregnancy rates occur when sperm meets the egg within four to six hours of ovulation, so having sex in the day or two leading up to ovulation gives sperm time to be in position and waiting.
The tricky part is knowing when ovulation is about to happen. A few tools can help. Ovulation predictor kits (available at any pharmacy) detect a hormone surge that typically occurs 24 to 36 hours before your egg is released. Tracking your cervical mucus is another reliable method. During your most fertile days, mucus becomes transparent, stretchy, and slippery, similar to raw egg white. That texture signals your body is preparing for ovulation. Basal body temperature tracking can confirm ovulation after the fact, which helps you predict the pattern in future cycles.
You don’t need to have sex every single day. Every one to two days during your fertile window covers your bases without adding unnecessary pressure.
Get to a Fertility-Friendly Weight
Weight plays a bigger role in conception than many people realize, and the effects work in both directions. Being underweight (a BMI of 18.5 or less) can cause your body to stop producing enough estrogen, leading to irregular cycles or a complete halt in ovulation. Being overweight creates the opposite hormonal problem: fat cells produce estrogen, and excess estrogen can trick your body into acting as though you’re already on hormonal birth control or pregnant, which also suppresses ovulation.
If you’re significantly over or underweight, even a modest shift toward a healthier range can restore regular ovulation. For women pursuing fertility treatments like IVF, obesity can also lower the success rates of those procedures.
What to Eat and What to Skip
A diet rich in vegetables, fruits, whole grains, fish, and healthy fats (the pattern often called a Mediterranean-style diet) is consistently linked to better fertility outcomes in observational research, though no single food is a magic bullet. The overall pattern matters more than any individual ingredient: whole, nutrient-dense foods support the hormonal balance and egg quality your body needs.
Alcohol is worth cutting back on. Women who drink more than seven alcoholic drinks per week are about 7% less likely to conceive, based on research in women undergoing fertility treatment. Less is better, and stopping entirely removes any risk. Caffeine, on the other hand, doesn’t appear to hurt your odds. Studies have found no measurable effect of caffeine consumption on pregnancy or live birth rates for either partner, so your morning coffee is fine.
Start Folic Acid Before You Conceive
The CDC recommends that all women capable of becoming pregnant take 400 micrograms of folic acid daily. This B vitamin is critical for preventing neural tube defects, and the key window for protection is the earliest weeks of pregnancy, often before you even know you’re pregnant. That’s why starting before conception matters. Most prenatal vitamins contain the right amount. If you’ve had a previous pregnancy affected by a neural tube defect, the recommended dose jumps to 4,000 micrograms daily, which your doctor would prescribe.
You may also see CoQ10 marketed as a fertility supplement for egg quality. The idea originated from an animal study showing improved egg development in mice given the supplement. However, those results haven’t been replicated in human clinical trials, and fertility specialists generally say the evidence doesn’t yet support recommending it for improving fertility in women.
His Health Matters Too
About a third of fertility challenges involve the male partner, so this isn’t just a one-person project. Several lifestyle factors have a measurable impact on sperm count and quality.
- Weight: Higher BMI is linked to lower sperm count and reduced sperm movement.
- Smoking: Cigarette smokers are more likely to have low sperm counts.
- Alcohol: Heavy drinking lowers sperm count, drops testosterone levels, and can cause erection problems.
- Heat exposure: Elevated scrotal temperature can impair sperm production. Wearing loose-fitting underwear and limiting time in saunas or hot tubs may help.
- Toxins: Regular exposure to pesticides, lead, and other chemicals affects both sperm quantity and quality.
- Medications: Certain blood pressure drugs, some antidepressants, opioids, and anabolic steroids can reduce fertility. If your partner takes any of these, it’s worth discussing alternatives with a doctor.
- Stress: Chronic stress can interfere with the hormones needed to produce healthy sperm and reduce sex drive.
Choose the Right Lubricant
This is a detail many couples overlook. Most lubricants, including saliva, slow sperm movement. Household oils like coconut oil are also problematic. If you need a lubricant while trying to conceive, look for one that is hydroxyethylcellulose-based, which is the closest match to natural vaginal mucus and doesn’t impair sperm motility. Avoid products with fragrances or parabens. Fertility-friendly lubricants are FDA-evaluated and usually labeled clearly on the packaging.
When to Get Help
The general recommendation is to seek a fertility evaluation if you haven’t conceived after one year of regular, unprotected sex. If you’re over 35, that timeline shortens to six months. If you’re over 40, it’s worth starting the conversation with your gynecologist right away rather than waiting. Age is the single largest factor in female fertility, and earlier evaluation gives you more options if treatment turns out to be needed.
Getting pregnant often takes longer than people expect. Among healthy couples with no fertility issues, it’s completely normal for conception to take several months. Focusing on the factors you can control, timing, nutrition, weight, and your partner’s habits, puts you in the strongest position each cycle.
