Sperm motility is defined as the capability of sperm to swim efficiently through the female’s reproductive tract for fertilizing an egg. However, to fertilize an egg your sperm should have progressive motility. This will allow your sperm to move at a speed of 25 micrometres per second, through the cervical mucus to fertilize an egg.
If you’re having low sperm motility, then this condition is known as Asthenospermia. This condition is determined when less than 32 percent of your sperm sample shows progressive motility.

Types of Sperm Motility
There are 2 types of sperm motility:
- Slow progressive motility – Sperms travel in straight lines or circular motion.
- Non- progressive motility – Sperms don’t move in straight lines and they move in small circles.
- No motility or absolute azoospermia – In this case, the sperm motility is zero.
Sperm Motility Percentage for Pregnancy
If you and your partner are planning for pregnancy, then you must have progressive sperm motility. Although it only takes one sperm and one egg to get pregnant, if your sperm has continuous motility then it will increase the chances of your partner getting pregnant.
If your sperm needs to fertilize an egg then it will have to travel through a female’s reproductive tract from the cervix to the uterus and then to the fallopian tubes. However, your sperm motility percentage should be around 40 to 75 percent for fertilizing an egg.
Your sperm count may also depend upon your overall health and lifestyle. Many studies have found that men with low sperm motility usually have a higher percentage of body fat. They have a higher Body Mass Index and also suffer from high blood pressure. So, if your body fat percentage is more and you’re are following an unhealthy lifestyle, then you may experience a higher metabolic syndrome. You may also tend to develop diseases like diabetes, heart diseases, and stroke. In case, if you’re diagnosed with low sperm motility, make sure you consult a doctor for examining your testosterone levels and your overall health condition.
