In this article, we will first break down some terms like sperm, semen, volume, and count and then have an in-depth review of vitamins that increase sperm volume.

Ready to learn about all the vitamins you can take to increase your sperm volume?  Good, let’s do it!

Fast Facts about Sperm and Vitamins to Increase Sperm Volume

  • Approximately 40-50% of infertility cases are caused by “male factor” infertility.
  • According to the World Health Organization, normal semen volume ranges from  1.5 to 7.6 milliliters per ejaculation .
  • Normal sperm count in ejaculate ranges from 39 million to 928 million.
  • Spermatogenesis, the process of producing sperm, takes approximately 72 days.
  • Many lifestyle factors are known to negatively influence sperm quality including smoking, excessive alcohol consumption, stress, lack of exercise, and more.
  • Fertility supplements like Vitamin C, D, E, CoQ10, Zinc, and others can help to improve sperm volume and quality and to boost overall male fertility. 

Key Male Fertility Terms to Understand

Before we get started on learning about vitamins that can increase sperm volume, it’s important we understand what sperm volume is along with other potentially confusing terms.


Spermatozoa (aka sperm) are the male reproductive cell or gamete. Human sperm is comprised of two main sections, the head (or body) and the tail known as a flagellum. The sperm swim through ejaculate and female reproductive fluids to reach and fertilize the female egg.


Semen, also known as seminal fluid, is the whitish male reproductive fluid that is emitted or ejaculated from the male reproductive tract which contains sperm suspended in seminal liquids that help keep the sperm cells alive and move through the female’s reproductive tract. 

Semen Volume

Semen volume is the amount of semen (fluid) you produce during ejaculation. 

Sperm Count

Sperm count is just as it sounds, a count of the total number of sperm in a man’s ejaculate. A sperm count is achieved by literally counting the number of sperm in a small sample of the man’s ejaculate and then multiplying that number by the total volume collected.

Sperm Density

As previously mentioned, what men should be focused on is their sperm count and the amount of sperm they have per ml of semen.  Semen volume is tied to sperm count by the parameter sperm density (sperm count per mL of semen).  Sperm density tells you exactly how many sperm are present in each ml of semen produced.  If sperm density remains consistent, then increasing semen volume will increase the total amount of sperm, but the two are not highly related. One man can have a large semen volume (liquid) but very little or no sperm.

Sperm Volume

Sperm volume isn’t a parameter that is measured in a clinical setting as it mixes the two terms Sperm Count and Semen Volume. That said, it is a commonly used term amongst the general public. 

For sake of this article we will use the terms sperm count and sperm volume interchangeable as semen volume is much less important in a clinical setting. Thus this article is really about vitamins to increase sperm count.

What is a Healthy or “Normal” Semen Volume, Sperm Count, and Sperm Density

According to the World Health Organization, normal sperm volume ranges from  1.5 to 7.6 milliliters per ejaculation .  Normal sperm count also has a wide range, with the low end being 39 million and the high end being 928 million.  Normal sperm density ranges from 15 million to 259 million sperm per mL of ejaculate.

Vitamins to Increase Sperm Volume/Count

Sperm volume can be affected by many factors including your age, diet, and exercise habits.  Most men make millions of new sperm every day, but men over the age of 40 have less healthy sperm than younger men.  A man’s semen volume, sperm count, and overall sperm quality decrease progressively between the ages of 20 and 80 – though age is must less of a factor for men then for women. 

If your sperm volume is low, or if you are just looking to give yourself the best chance possible to have a baby, check out some of the vitamins known to increase sperm volume below.  

Vitamin D

Research has shown that nutrition has a significant impact on male fertility and sperm count, especially vitamin D.  In 2019, researchers reviewed 18 studies on vitamin D’s impact on male fertility and sperm volume.  They found that men with higher levels of vitamin D showed improved fertility, especially sperm volume .  

Studies have shown that around 40% of adults in the U.S. suffer from Vitamin D deficiency. Vitamin D is produced by the body in response to exposure to the sun.  It can be difficult for the body to get appropriate levels of Vitamin D through diet and sun exposure alone, especially during the winter months. To ensure you are getting an adequate amount of vitamin D to support sperm quality and increase sperm volume, fertility specialists recommend taking vitamin D supplements.

Vitamins C and E

Vitamin C is an antioxidant that supports many functions of the body and is known to reduce cellular damage.  Studies have shown that supplementing vitamin C can help to improve several different semen parameters for infertile men, especially sperm volume.  In one study, researchers found that when men took vitamin C supplements twice daily for 2 months the mean sperm volume increased by more than 100% .  Participants in the study also saw an increase in sperm motility and a decrease in the number of deformed sperm cells.  

Other studies have focused on vitamin C’s ability to improve semen parameters when combined with other supplements.  In a 2016 review of multiple studies, researchers concluded that supplementing vitamins C and E together can help to significantly improve sperm volume .  Vitamin E is known to improve the function of other antioxidants, like vitamin D, because it prevents lipid peroxidation.  As such, it comes as no surprise that when you combine vitamin E with other antioxidants known to increase sperm volume like vitamin D and Coenzyme Q10, you see better results.  

Coenzyme Q10 (Co-Q10)

Coenzyme Q10 (Co-Q10) is another antioxidant that can improve many bodily functions in men.  Co-Q10 is an essential antioxidant that helps to generate energy in human cells.  Studies have shown that supplementing Co-Q10 can help to significantly improve sperm volume, especially in infertile men

Co-Q10 is found naturally in seminal fluid.  A higher concentration of CO-Q10 in sperm is highly correlated with greater sperm volume and motility.   In a prospective study of Co-Q10’s effect on men suffering from infertility, researchers found that supplementing Co-Q10 resulted in a significant increase in sperm density .  As discussed earlier, sperm density is closely tied to sperm volume.  An increase in sperm density means that more sperm are present per mL of semen.  Fertility specialists believe that Co-Q10 helps to increase sperm volume due to its antioxidant properties and its contributions to cell energy production.

Vitamin B-12

It makes sense that vitamin B-12 would contribute to increased sperm production because it is involved in the metabolism of every cell in the human body.  Research has shown that male sperm counts are declining as time goes on due to environmental factors like pesticides interfering with spermatogenesis.  In response, scientists have tested a number of nutritional therapies to improve sperm volume.  They have found that antioxidants, like the ones discussed above, and vitamin B-12 can help to combat the negative effects of environmental factors on spermatogenesis.  Research has concluded that vitamin B-12 plays a particularly important role in sperm development and that supplementing B-12 can help to significantly improve sperm volume .  

Due to vitamin B-12s ability to improve sperm parameters, especially volume, fertility specialists have proposed it as a candidate therapy to enhance sperm quality and to manage infertility.  


Studies have shown that low zinc levels are associated with poor sperm quality, low sperm volume, and an increased risk of male infertility .  As such, getting appropriate levels of zinc is considered essential for male fertility.  Zinc can be found naturally in foods like meat, fish, and eggs.  Many men, especially vegetarians are unable to attain adequate levels of zinc through food alone.  In fact, 17.3% of the global population suffers from zinc deficiency.  

In addition to improving sperm volume and other semen parameters, zinc is known to support male fertility by increasing testosterone.  Testosterone is required for sperm production and supplementing zinc has been shown to increase testosterone.  Many men who “over-exercise” or participate in extremely strenuous exercise multiple times per week are at a higher risk for suffering from low testosterone.  Studies have shown that zinc supplementation can specifically help infertile men with low testosterone to improve their sperm volume .

Omega 3s

Omega 3s have a wide range of health benefits, including that they play a vital role in the structure and formation of all human cells, including sperm.  Since omega 3s are essential to sperm cell growth, it comes as no surprise that supplementing them can improve sperm quality.  Studies have shown that fertile men with normal sperm volume have higher levels of omega 3s compared to infertile men with low sperm volume .  

Other studies have shown that omega 3 supplementation can improve sperm volume for infertile men and it can help to improve pregnancy outcomes for couples undergoing fertility treatment .  Oligoasthenoteratozoospermia aka OAT (low number of sperm, poor sperm movement, and abnormal sperm shape), is the most common cause of male subfertility.  Fertility specialists believe that men suffering from OAT may benefit from taking an omega-3 supplement daily. 

Omega 3s are found primarily in seafood. If you don’t eat a lot of fish, there is a good chance you aren’t getting enough omega 3s.  A study conducted by the American Heart Association found that a low percentage of the adult population in the U.S. consumes the recommended level of omega 3s each week.  They found that men had a greater percentage of not meeting the requirements compared to females.  The study concluded that supplementation of omega 3s, in addition to food sources, may be necessary for adults, especially men, to meet recommendations .
