Males who ejaculated daily saw declines in sperm count. Other measures of sperm quality — such as shape, ability to swim, and concentration — remained about the same, even with frequent ejaculation.
Together, these studies suggest that in males with reduced fertility, frequent ejaculation might lower the chances of conception by lowering sperm count slightly. Sperm work best at cool temperatures. The testicles help keep sperm cool by descending from the body. Prolonged exposure to heat — such as from hot tubs, intense exercise, or workplace equipment — may damage sperm.
Males who want to improve fertility should wear loose fitting underwear. Snug underwear may trap heat and force the testicles against the body, increasing temperature further.
Anything that affects overall health may also affect sperm production, since sperm health depends on a complex interaction of several hormones and bodily systems. For example, excessive drinking, drugs, and smoking may affect fertility.
Exercise can improve blood flow and overall health, potentially improving sperm quality. Some studies suggest that getting regular exercise may improve sperm quality or count, though more research is needed to explain why. It is also important to eat a healthful, balanced diet. Research has linked some foods with lower sperm health. These foods include processed meats, trans fats, soy products, and high fat dairy products. However, most research has found only a correlation — not a causal relationship — between these foods and lower sperm counts.
To improve the chances of conception, people can time when they have sexual intercourse to line up with when they are at their most fertile. Egg cells live for only 12—24 hours after ovulation , which means that timing sex for immediately before or after ovulation improves the chances of conception.
A study found that the first fraction of ejaculate contains the highest concentration sperm, and that these sperm move more effectively and are of a higher quality than those later in ejaculate. So, it is important for a male to ejaculate directly into their partner to ensure that these early sperm have a chance to travel to the egg. Using ovulation predictor tests, monitoring female signs of fertility such as cervical mucus, and having regular sexual intercourse may also increase the odds of conceiving.
Ovulation predictor kits are available for purchase in stores and online. As the body is constantly producing sperm cells, a healthy male will usually always have some sperm cells in their semen.
