Not all causes of a couple’s infertility are related to the female. Male infertility accounts for around 30% of all cases. Male factor infertility is an issue for many couples struggling to conceive. Luckily, there are many assisted reproductive technologies (ART) available for couples who wish to conceive.
The root cause of male infertility is not always easy to establish. For approximately 50% of men diagnosed with infertility, the exact cause remains unknown. Usually, male factor fertility problems have to do with quality or quantity of sperm, though there is an issue with ejaculation that can contribute to these problems. While lifestyle choices are often involved, many men have several conditions combined that lead to infertility.
Azoospermia is defined as the complete absence of sperm in the ejaculate/semen. This problem affects around 5% of men who have infertility issues. It may be that the body does not produce any sperm, or it could result from blockage/obstruction in the ejaculatory ducts or vas deferens. This may prevent the sperm from leaving the testicles.
