What are the Causes of Asthenozoospermia?
Sperm health is as important as uterus health in a couple's process of conceiving. When evaluating sperm health, the following criteria are looked at:
- Ability to reach the egg through the cervical mucus
- Acrosome reaction
Abnormalities in any of the above sperm criteria lead to infertility in males. Motility is an essential parameter in reproduction. The ability of the sperm to successfully reach the egg and fertilise it is motility. Asthenozoospermia is the medical term used for diminished sperm motility.
Causes of Asthenozoospermia
There are many causes of Asthenozoospermia including the below-mentioned ones:
Inflammation: Inflammatory diseases of the sperm duct prostrate or any other reproductive organ can reduce the motility of sperms. The microorganisms from these diseases can directly affect the sperm slowing down its speed and the ability to penetrate the cervical mucus.
Varicocele: In this condition, the veins inside the scrotum become enlarged. This is one of the common causes of Asthenozoospermia in men.
Abnormal semen liquefaction: Abnormal semen liquefaction reduces the space for sperm activity and hinders the movement of sperm.
Chromosome abnormalities: Peculiarities of sex chromosomes can not only affect sperm quantity but also the mobility of sperms, thereby increasing the chances of infertility.
Immunological factors: Antisperm antibodies obstruct sperm activity in varied ways. Studies have suggested that the presence of antisperm antibodies around the sperm tail deters its ability to penetrate the cervical mucus.
Lifestyle and environmental factors: Certain unhealthy lifestyle habits greatly affect sperm motility. For example, smoking, excessive drinking, and use of drugs can cause the condition. Also, men who have jobs like driving or horse riding that causes repeated trauma to the pelvic area be at risk for Asthenozoospermia.
In conclusion, sperms are of critical value in male fertility and should be healthy. The number of motile sperms should be above 70% after ejaculation. If the motile sperms are less than 40%, it can be termed as asthenozoospermia. However, depending on the severity of the disorder, pregnancy can still be achieved using IVF and making certain lifestyle changes.
