The Important Role of Sperm Motility for Fertility and Conception

Improving sperm motility can make a big impact on conception rates

Sperm quality has profound implications on men’s fertility and the chances of a healthy conception.  Decades of scientific research prove that it is possible to improve sperm quality and even improve the quality of the DNA within the sperm by taking the right vitamins, minerals, and antioxidants. The benefits to increasing your sperm quality includes increasing your chances of conceiving (whether naturally or with assisted reproduction, such as IUI or IVF), and reducing the risk of miscarriage and birth defects. Beli was formulated with nutrients that are clinically proven to support improving all sperm parameters. 

Sperm quality is measured in several dimensions:

  • Sperm quantity, the count and concentration of sperm in semen
  • Sperm morphology, shape and the size of the sperm (read our blog here)
  • Sperm Motility, the manner and speed with which sperm swim
  • DNA fragmentation within the sperm 

Sperm motility describes the ability of sperm to move properly through the female reproductive tract or through water to reach the egg. Sperm motility can also be thought of as the quality, which is a factor in successful conception; sperm that do not "swim" properly will not reach the egg in order to fertilize it.

In order to successfully fertilize the egg, sperm have to swim a great distance compared to their microscopic size. Let’s take a deep dive into the role of sperm motility in conception, including info on the science-backed nutrients that studies show can help get your sperm in top swimming shape. 

What is Sperm Motility?

Sperm motility refers to the ability of each sperm cell to move. Healthy sperm are designed to swim forward with enough strength to move through the vaginal canal and cervix, up into the uterus and fallopian tube in order to fertilize the egg. This journey takes an average of 2 to 10 minutes after ejaculation. It’s a long way to go for a microscopic cell!

 Sperm motility analysis is a part of routine semen analysis, a test your doctor can order to assess your fertility. Motility is assessed by both total motile sperm count, or TMSC, the number of sperm cells that are moving out of all the sperm available in a sample, and by average path velocity, or VAP, the speed with which they move. 

The progress sperm make when they move is also important. Progressive motility refers to sperm that move in a straight line or very large circles. Progressively motile sperm are the most likely to successfully complete the long journey to the egg. Non-progressive motility describes sperm that swim in tight circles, or wiggle in one place.

In a normal-range semen sample, there are at least 20 million motile sperm. Poor sperm motility occurs when there are fewer than 5 million motile sperm in a sample. 

Conception is largely about increasing your odds, so motility matters—a lot! The more strongly swimming sperm present in semen, the better the chances that one of them will reach the egg and fuse successfully.                                                

What Affects Sperm Motility?

It is generally known that most men produce millions of new sperm every day. However, you might not know that it takes these new sperm about 3 months to fully mature. You also might not realize that when sperm are initially formed within the testicles, they lack the ability to swim forward or fertilize an egg until they make their way through the reproductive tract.  Every day is important in the life of sperm and feeding them these nutrients are key to their healthy development.  Sperm motility starts to decline around age 35, and age also negatively impacts sperm count and morphology.

Usually, when sperm motility is poor, there are other problems found with sperm health. For example, men with poor sperm motility may also have low sperm counts or poor sperm morphology (or sperm shape). Sperm that aren't formed properly can't swim properly.

Men’s fertility health can be influenced by a range of genetic, environmental, and lifestyle factors, and it’s common for the causes of infertility and subfertility to remain unexplained. Some causes of poor sperm motility include:

 

  • Poor diet
  • Nutritional deficiencies
  • Age
  • Damage to the testicle from injury, cancer, infection, or surgery
  • Long-term use of steroids, cannabis, alcohol or cocaine
  • Smoking
  • Varicocele, a condition where the veins in the scrotum become enlarged
  • Working with chemicals and machinery

When it comes to sperm health, many factors are beyond our control. But science has proven it’s possible to improve sperm motility without medicine using the factors we can control, including ensuring you have the right nutrients that fuel optimal sperm motility. 

Nutrients to Improve Sperm Motility

We formulated Beli Vitality for Men based on findings from several studies that showed supplementing with key nutrients can significantly improve all facets of sperm health, including sperm motility. Beli Vitality is a men’s prenatal that contains evidence-based levels of nutrients shown in clinical studies to help strengthen sperm motility and increase the chance of conception.

The evidence for supporting sperm health by taking key supplements is strong. In one cornerstone study, researchers saw improvement in sperm motility, morphology, or both in 52% of the participating infertile men who took selenium and vitamin E for at least 100 days.


  • Vitamin C: Vitamin C is an essential antioxidant that helps protect the body’s cells from damage and oxidative stress and free radicals. Vitamin C is one of the most abundant antioxidants that can be found in semen and is one of the biggest contributors to protecting the sperm’s DNA from free radical damage.
  • Vitamin D: The benefits of vitamin d have been well established and the benefits of vitamin d for male fertility is just as important for men’s fertility. Vitamin D also plays a vital role in supporting sperm motility. Studies show that increasing your vitamin D levels can have a positive impact on improving your sperm motility. 
  • Vitamin E: Oxidative stress can lower sperm parameters, one recent study found that vitamin E helps protect the sperm’s cell membrane and protect against oxidative stress and free radicals. 
  • Zinc: When it comes to male fertility, zinc is one of the most important trace elements. 
  • CoQ10: CoQ10 helps improve sperm motility by combating oxidation and protecting sperm from radical damage.
  • N-acetyl-l-cysteine: Studies show that when supplementing with NAC when compared to a placebo, NAC can significantly improve sperm motility. 
  • Vitality BlendTM with Shilajit: Beli for Men includes all natural Shilajit, an ancient adaptogen tha has been clinically proven to improve sperm motility, boost sperm count, and improve sperm quality.

The single most important thing you can do to improve sperm motility and overall quality is to take Beli Vitality for Men which is specially formulated with the right combination of nutrients that have been clinically proven to improve sperm motility that can help make a significant difference in your chance of a successful pregnancy.
