Why Does Sperm Motility Matter?
Sperm must move quickly and in the right direction to reach the egg.
- Healthy sperm travel through the female reproductive tract to reach the egg.
- Once they reach it, they can help with fertilization.
- Because of this, motility is a key sign of a man’s fertility potential.
What Is Normal Sperm Motility?
Under general guidelines, total sperm motility should be about 40% or more.
- At least 32% of sperm should show progressive motility.
- Progressive motility means sperm are moving forward actively, not in circles or in place.
- These sperm have the ability to reach the egg.
If your numbers fall below these levels, your motility is considered low.
What Causes Low Sperm Motility?
There is usually no single cause. Medical, lifestyle and environmental factors can all play a part.
Medical causes
- Infections: Some infections in the reproductive tract can reduce sperm movement.
- Varicocele: The blood vessels around the scrotum (the skin bag holding the testicles) become enlarged.
- Medications: Certain medicines can affect sperm motility.
- Steroids or gym drugs: Drugs used for bodybuilding can also lower motility.
Lifestyle causes
- Smoking
- Excessive alcohol use
- Obesity
- Stress
Environmental causes
- Exposure to toxins or harmful chemicals
