Semen production is a natural and key element of the male reproductive system, but there are things that can affect semen levels. Some men suffer from health conditions that result in low semen levels, while lifestyle choices also can determine whether semen levels are normal or low. For example, a man who follows a healthy diet is more likely to have normal semen levels than someone who imbibes in drugs, alcohol and tobacco products. Other lifestyle choices also can make a difference in semen production.
Sexually transmitted diseases are among the health conditions that affect both semen levels and sperm quality. Any type of injury or damage to the male reproductive system also can affect both. Age also plays a role in how much semen a man produces, with levels dropping slightly as a man ages.

Men who want to produce more semen but drink alcohol are often advised to reduce their consumption or eliminate it from their diet altogether, because this tends to decrease semen levels. Smoking cigarettes can have the same effect, so men worried about their semen quantity should quit this habit. Recreational drugs, especially steroids, also tend to reduce the production levels of semen and should be avoided. Even some prescription drugs may have this effect, so they should be taken only when necessary. Other lifestyle choices, including wearing roomy underwear and avoiding hot tubs and saunas, also can help boost low levels.

Once men eliminate the toxins from their life, they are encouraged to increase certain vitamins to boost semen. For example, zinc supplements are encouraged, because this nutrient can increase semen production while improving sperm motility. Amino acids are known to do the same thing, which is why supplements that contain L-lysine, L-carnitine and L-arginine are frequently recommended. It is often possible to find a single pill that contains several of these vitamins, because there are various supplements marketed toward men who are looking to increase their semen production.

Some tips do not require men to purchase anything and often result in good general health. For instance, staying hydrated is usually considered one of the best ways to increase semen production, because there is a lot of water in semen. It is usually recommended that men drink eight or more glasses of water, especially on days when they work out. Regular exercise is another way to make more semen while staying generally healthy, as long as the water that is lost is quickly replaced. Finally, men who stay near the ideal weight for their height tend to have good semen levels, while overweight men may find production drops off.
