Male infertility refers to the inability of a man to impregnate a woman due to factors affecting sperm production, motility or function. It can be influenced by various factors. Here are six key reasons that can contribute to male infertility:
One of the primary causes of male infertility is low sperm count. This condition refers to a lower-than-normal concentration of sperms in the ejaculate. A low sperm count reduces the chances of fertilising an egg, making conception more challenging.
Sperm motility is crucial for sperm to travel and penetrate the egg. If sperms have poor motility (slow movement), they may struggle to reach the egg, hindering the fertilisation process.
Varicocele is a common condition characterised by the enlargement of veins within the scrotum. It can lead to increased testicular temperature, which negatively affects sperm production and function.
Difficulties in achieving or maintaining an erection, as well as disorders related to ejaculation, can contribute to male infertility. These issues may prevent the delivery of sperm into the female reproductive tract during intercourse.

Certain lifestyle choices and environmental exposures can contribute to male infertility. Factors such as smoking, excessive alcohol consumption, drug use, exposure to toxins or pollutants and high levels of stress can negatively impact sperm health.
