4 Steps To Improve Sperm Count With Amino Acids

Having trouble conceiving?

If you and your partner have been trying unsuccessfully to have a baby for several months a fertility specialist may recommend a semen analysis. This is one of the common assessments used to measure a range of parameters that contribute to healthy male fertility.

The following video explain in more detail how a semen analysis helps to determine current male fertility

Often low sperm count and poor sperm motility account for sub-fertility problems in men. A normal sperm count should be above 40 million per millilitre of semen. At least half these sperm should exhibit forward motility.

The good news is that if the results of a semen analysis reveal a low sperm count and/or poor motility there are plenty of ways to improve sperm health.

Use amino acids to help to improve sperm count

For men struggling to conceive certain lifestyle adjustments can improve fertility. Paying close attention to diet is important. Foods rich in certain amino acids can help to improve sperm parameters. Three key amino acids for healthy sperm include:

  • L-arginine
  • L-carnitine
  • N-acetyl cysteine (NAC)

These amino acids have a range of positive influences on the development and function of sperm. They can also benefit overall reproductive health and vitality. By following the four steps outlined below, it’s possible to enhance male fertility

Step 1 – Increase L-arginine intake

The semi-essential amino acid L-arginine is important for a wide range of physiological functions. In addition to boosting the immune system it also helps with reproductive health.

Increases blood flow

Required for the production of nitric oxide, this amino acid assists in the dilation of blood vessels and circulation. This makes it easier to get an erection. Better blood flow also helps to deliver vital nutrients needed to support developing sperm.

Increases sperm count and motility

Many studies have shown that L-arginine supplementation can elevate sperm count1,2. Other research has also confirmed that this amino acid also improves sperm motility3,4. In fact, all semen parameters appear to benefit from L-arginine supplementation5.

To boost your daily intake of L-arginine eat foods such as red meat, poultry, fish, and dairy products. These proteins can form part of your evening meal. If you want a break from meat and dairy, there are also other non-animal sources of L-arginine. Good plant sources of this amino acid include walnuts, peanuts, sesame seeds, soybeans, and pumpkin seeds. Grains such as oats, wheat germ, and quinoa are also high in L-arginine.

 

Step 2 – Increase L- carnitine intake

Another semi-essential amino acid, L-carnitine has many roles in supporting the male reproductive system. It is involved in:

L-carnitine is needed to help in the formation and growth of sperm within the testes. It has a significant part in the development of the protective sperm membrane. This amino acid is also vital for forward motility. It is required as an energy source.

salmonWithout sufficient levels of L-carnitine, sperm health declines. Many studies have shown that supplementation with this key amino acid can help to enhance sperm count, motility, and morphology6, 789.

Similar to L-arginine, some of the best sources of L-carnitine include fish, red meat, poultry, and dairy products. Wheat, tempeh, avocados, peanuts, and asparagus also contain a reasonable amount of this amino acid.

Step 3 – Increase N-acetyl cysteine (NAC) intake

NAC is a modified form of the amino acid L-cysteine. It has powerful antioxidant effects. Not only does it help to protect sperm, it also boosts overall semen quality. Studies show that NAC supplementation can decrease oxidative stress in semen. This helps to enhance sperm motility, count, and quality10,11,12.

L-cysteine is a semi essential amino acid. Foods rich in L-cysteine include soy, eggs, poultry and nuts. However, in its modified form, NAC is more potent. NAC has a stronger positive influence on semen parameters than L-cysteine. This is why many nutritionists and fertility specialists recommend taking a NAC dietary supplement.

This leads into step 4 of enhancing sperm count using amino acids.

Step 4 – Supporting healthy sperm with supplements

Changing your diet to include key amino acids that support healthy sperm is one step closer to boosting fertility. However, amino acids also need the support of other nutrients. There are also important vitamins, minerals, and trace elements required to improve semen parameters.

Selecting a quality fertility supplement can help to ensure that the body has everything it needs to produce healthy, viable sperm. It’s always important to discuss your supplement options with a fertility specialist first. This helps to rule out any underlying health risks. It can also help to make sure you get the ingredient combination for your needs.

Don’t stop there

Following the four steps above is a great start to enhancing reproductive health. Utilising amino acids to improve sperm count and other semen parameters can increase the chances of conceiving a baby. However, to optimise your reproductive health you need to take into consideration other factors. Remember to exercise regularly, don’t smoke, cut back on your alcohol consumption, and limit stress.
