Azoospermia, or no sperm in the ejaculate, is more common than you may think - approximately 4% of all men who have a semen analysis have no sperm in the ejaculate.

What is azoospermia

Approximately 4% of men have azoospermia diagnosed via semen analysis. This can be a shocking piece of news to receive and is a finding which needs careful and sensitive further investigation. However, with the correct investigations and treatment plan, men with azoospermia can often go on to conceive. Depending on the type of azoospermia, it may be treated with surgery to result in sperm in the ejaculate or with sperm retrieval for IVF or ICSI.

Obstructive azoospermia

Occurs when the testicles produce sperm but, due to a blockage, it is unable to reach the ejaculate. The blockage could be anywhere along the journey from sperm maturation to ejaculation. Obstructive azoospermia may be due to injury, prior surgery, infection or genetic abnormality.

Non-obstructive azoospermia

Refers to a lack of sperm production. Little or no sperm is produced and what is produced does not make it out of the testicles. Non-obstructive azoospermia may be a result of a varicocele, genetic abnormalities, hormones, infections (current or past), undescended testicles or injury.

Why choose Fertility Solutions to investigate your azoospermia

Successful pregnancy following a diagnosis of azoospermia is made possible by male fertility specialists, such as those at Fertility Solutions.

An expert eye

It is crucial that your semen analysis to assess azoospermia is performed by a qualified, consultant embryologist as meticulous examination of the ejaculate is essential to provide an accurate diagnosis and it takes an exceptionally trained eye to do so. Embryologists routinely work with sperm for assisted reproductive procedures and therefore are best placed to assess and diagnose any semen analysis abnormalities.

Outstanding service

Our consultant embryologists and urologists explain your azoospermia to you, discuss your treatment options, help you on your fertility journey and deliver outstanding care. Whatever the solution to your azoospermia is you can be confident that you are in the best hands with the expert team at Fertility Solutions.

What next?

The treatment options for azoospermia really depend on the cause. A microsurgical reconstruction to locate and repair the blockage to restore normal flow of sperm to the ejaculate is often a good option for obstructive azoospermia. Although complex, this procedure has high success rates when performed by a skilled urologist.

Azoospermia may also be treated by a micro TESE (sperm retrieval) – direct harvesting of sperm from the testicle for reproductive treatment such as IVF or ICSI. Non-obstructive azoospermia often responds well to medical treatment to encourage and boost sperm production. We work with Mr Jonathan Ramsay, leading male fertility urologist.
