Improving ovulation comes down to giving your body the hormonal, nutritional, and metabolic conditions it needs to mature and release an egg each cycle. Whether your cycles are irregular, you’ve been diagnosed with a condition like PCOS, or you simply want to optimize your fertility, several evidence-based strategies can make a meaningful difference. Most of them center on the same principle: reducing the things that disrupt your hormonal signaling and increasing the things that support it.
How Ovulation Works
Understanding the basics helps explain why certain changes matter. Your brain’s hypothalamus releases a signaling hormone in small pulses. Slow pulses trigger production of follicle-stimulating hormone (FSH), which causes follicles in your ovaries to grow and mature between roughly days 6 and 14 of your cycle. Faster pulses trigger more luteinizing hormone (LH). Around day 14, a sudden LH surge causes the most mature follicle to rupture and release its egg.
Anything that disrupts this pulsing signal, whether it’s chronic stress, extreme exercise, very low body weight, or insulin resistance, can delay or prevent that LH surge. That’s why improving ovulation isn’t about one magic fix. It’s about clearing the obstacles that interfere with this chain of signals.
Adjust Your Diet Toward a Fertility Pattern
A dietary pattern introduced in 2007 and known as the “fertility diet” has been consistently linked to a lower risk of ovulatory infertility. The core principles: eat more beans, whole grains, vegetables, fruits, and iron-rich foods while cutting back on fast food, sugary drinks, and alcohol. Research shows that healthier eating patterns along these lines are associated with shorter time to conception, higher fertility rates, and a lower risk of infertility caused by ovulatory disorders.
A few specific swaps stand out. Replacing animal protein, particularly chicken and red meat, with plant-based protein sources like lentils, chickpeas, and beans may reduce the risk of anovulation (cycles where no egg is released). Choosing foods with a low glycemic index also helps. That means favoring non-starchy vegetables, legumes, berries, apples, pears, whole-kernel bread, brown rice, and steel-cut oats over refined grains, white bread, pasta, and white potatoes. Low-glycemic diets have been shown to improve insulin sensitivity, regulate menstrual cycles, and reduce excess androgen levels in women with PCOS.
Fat quality matters too. Diets higher in monounsaturated fats (olive oil, avocados, nuts) and lower in trans fats improve HDL cholesterol, triglyceride levels, and insulin sensitivity. Some research also suggests choosing full-fat dairy over low-fat dairy may positively influence ovulatory function, though the evidence on this is less definitive.
Manage Your Weight Within a Functional Range
Body weight affects ovulation at both extremes. A large analysis of nearly 15,000 fertility patients found that cumulative live birth rates increased as underweight women gained weight, held steady for women with a BMI between 18.5 and about 30, and dropped for women with a BMI above 30. Obesity is associated with ovulatory dysfunction, partly because excess fat tissue increases insulin resistance and alters hormone levels.
If you’re above a BMI of 30, even a modest weight loss of 5 to 10 percent of your body weight can restore more regular ovulation. The goal isn’t reaching an “ideal” number on the scale. It’s getting into that functional range where your hormonal signaling works well. If you’re underweight, gaining even a few pounds can be equally important, since too little body fat suppresses the hypothalamic signals that drive your entire cycle.
Find the Right Exercise Balance
Moderate physical activity supports ovulation by improving insulin sensitivity and reducing inflammation. But too much exercise, especially combined with insufficient calorie intake, can shut down ovulation entirely. This condition, called functional hypothalamic amenorrhea, happens when intense training disrupts the pulsing hormonal signal from your hypothalamus, causing FSH and LH to drop and estrogen levels to fall.
In one documented case, a woman who reduced her exercise volume by more than 50 percent (down to about 30 minutes, three times per week) saw her LH, FSH, and estrogen levels increase within three months. Normal periods returned at five months, along with a small weight gain of about four pounds. If you’re exercising heavily and your periods have become irregular or stopped, pulling back on training volume is one of the most effective things you can do. The goal is consistent moderate activity, not extremes in either direction.
Reduce Chronic Stress
Stress doesn’t just “feel” like it disrupts your cycle. It does so through a specific biological pathway. When you’re chronically stressed, your adrenal glands release cortisol and other stress hormones. Research published in PNAS found that these stress hormones activate a signaling molecule in the brain that directly suppresses the release of GnRH, the master hormone that kicks off the entire ovulation cascade. The result is lower LH output and, ultimately, failed or delayed ovulation. Removing the source of stress hormones in the study completely prevented this suppression.
You can’t eliminate all stress, but you can reduce chronic exposure. Regular sleep, manageable exercise, mindfulness practices, and addressing sources of ongoing psychological strain all help lower baseline cortisol. The reproductive system is remarkably sensitive to signals that the body is under threat, so even partial stress reduction can make a difference.
Supplements That Support Ovulation
Two supplements have the strongest evidence for improving ovulatory function.
Myo-inositol is particularly well-studied in women with PCOS. The Society of Obstetricians and Gynaecologists of Canada recommends 4 grams daily, split into two 2-gram doses. For optimal results, combining myo-inositol with D-chiro-inositol in a 40:1 ratio (4 grams of myo-inositol plus 100 milligrams of D-chiro-inositol) has been shown to help restore ovulation in women with PCOS. Inositol works primarily by improving how your cells respond to insulin, which in turn helps normalize the hormonal environment needed for follicle development.
CoQ10 supports egg quality rather than ovulation timing. It’s a powerful antioxidant that helps mitochondria produce energy more efficiently, which matters because egg cells are among the most energy-demanding cells in your body. In women with poor ovarian response, CoQ10 supplementation led to more eggs retrieved, higher fertilization rates, and more high-quality embryos. In women with PCOS, combining CoQ10 with standard ovulation-stimulating medication produced more follicles, higher ovulation rates, and significantly higher pregnancy rates than medication alone. Recommended doses range from 150 to 600 milligrams daily.
A daily multivitamin containing iron and folic acid also scores well in the fertility diet research. Higher intake of supplemental iron and multivitamins is associated with better ovulatory outcomes.
Track Whether You’re Actually Ovulating
Before you can improve ovulation, it helps to know whether and when it’s happening. Two common home methods each have trade-offs.
Ovulation prediction kits (OPKs) detect the LH surge in your urine before ovulation occurs, which makes them useful for timing intercourse. The downside is that you can miss the surge if you skip a day of testing or if your urine is too dilute when you test. LH strips work best for women with fairly regular cycles.
Basal body temperature (BBT) tracking involves taking your temperature first thing each morning and watching for a sustained rise of about half a degree, which confirms ovulation happened. The limitation is that by the time your temperature spikes, ovulation has already passed, so BBT confirms ovulation after the fact rather than predicting it. It’s most useful for identifying patterns over several cycles.
Using both methods together gives you the most complete picture: OPKs to predict when ovulation is approaching and BBT to confirm it actually occurred.
When Lifestyle Changes Aren’t Enough
If you’ve optimized your diet, weight, exercise, and stress levels and you’re still not ovulating regularly, prescription medications can help. The two most commonly used options are clomiphene citrate and letrozole, both taken as short courses of oral pills early in your cycle. Both work by prompting your body to produce more FSH, stimulating follicle growth. Success rates per cycle are around 21 percent for clomiphene, and letrozole performs similarly overall but tends to work better for women with PCOS. Your doctor can help determine which is appropriate based on your specific situation and test results.
