Causes of Infertility in Men

One in six couples have difficulties falling pregnant. Overall, one-third of infertility cases are caused by male reproductive issues, one-third by female reproductive problems and another third by both male and female reproductive challenges or by unknown factors.

Causes of male infertility may include:

Male fertility tests

Lifestyle changes can make a huge difference to a man’s fertility and to the success of fertility treatment. However, not all causes are easy to treat. Some physical causes like abnormal sperm delivery or physical trauma are hard or impossible to treat naturally.
Your GP or fertility specialist will perform an initial assessment.

Semen analysis

Check whether there are problems with your sperm, e.g. low sperm count, sperm motility and sperm morphology (size and shape)

DNA fragmentation

Assess the DNA of your sperm

Antisperm bodies

Check if you are producing antibodies against your own sperm

Blood tests and or urine sample

Assess your general health with blood tests and a urine sample to test for chlamydia (which may affect your fertility)

Male fertility treatment options


In cases where the azoospermia is caused by mechanical blockage to the sperm flow, then TESA or testicular sperm aspiration can be used to extract the sperm. A mechanical blockage occurs in men who have had a vasectomy, or who are missing the vas deferens.

A TESA procedure is minimally invasive and can be done in your doctor’s office under local anaesthetic. A needle is inserted into the testicle and tubules where sperm is aspirated through a syringe. As no incisions are made, you won’t need any stitches.
