Sperm motility is the ability of sperm to move or swim progressively. On the other hand, the inability of sperm to move or swim properly is known as asthenozoospermia or asthenospermia, and it results in male infertility. Sperm motility is also defined as the percentage of all the moving sperm in a semen sample. The normal percentage should be 50% and above. Anything less than that amounts to low sperm motility, and that carries the risk of infertility.
Importance of Sperm Motility
Sperm motility is an important factor in a couple’s ability to conceive. This is because sperm ejaculated into the vagina have to swim all the way to meet, penetrate, and fertilize the female egg. Unfortunately, not all the ejaculated sperm survive the tough journey to meet the egg. If the sperm cannot swim to meet the egg it then means fertilization cannot take place. Thus, couples concerned in this case cannot conceive, naturally.
However, a man with low or zero sperm motility can still impregnate a woman with the help of assisted reproductive technology (A.R.T.) like Invitro Fertilization (IVF).
Sperm motility is one of the factors or parameters examined when conducting semen analysis. The other factors are sperm count, semen volume, sperm morphology, rate of semen liquefaction, etc.
Types of Sperm Motility
There are three types of sperm motility problems:
- Slow or sluggish progressive motility
- Non-progressive motility (less than 5 micrometre per second
- Zero motility
Causes of Low Sperm Motility
The causes of low sperm motility varies. These include:
- Genetic cause
- Disorder in male accessory sex gland secretion that results in gland emptying more slowly
- Lifestyle and environmental factors, e.g. smoking more than 10 cigarettes daily, jobs that involve sitting longer hour such as driving, etc.
- Undiagnosed medical condition
How Low Sperm Motility is Diagnosed
Low sperm motility is diagnosed through routine semen analysis. Semen analysis result that shows less than 40% of sperm motility means that there’s a problem of low sperm motility.
Treatment for Low Sperm Motility
The various treatments for low sperm motility include the following:
- Lifestyle changes e.g. regular exercises, reduction of alcohol consumption, quitting smoking, limiting cell phone exposure, etc.
- Assisted reproductive technology (A.R.T.) e.g. I.V.F, I.U.I, etc.
