Azoospermia
No Sperm in Semen
Azoospermia means that no sperm are identified in the ejaculate. The next step is determining why — because the underlying cause can significantly change your fertility options.
Specialist assessment can distinguish a blockage from reduced sperm production and guide treatment, including microsurgical reconstruction, sperm retrieval or micro-TESE when appropriate.
✓ Determine whether azoospermia is obstructive or non-obstructive
✓ Targeted hormone and genetic assessment when indicated
✓ Microsurgical and sperm retrieval options available
What is Azoospermia?
Azoospermia means no sperm are detected in the semen on laboratory testing. It is an important cause of male infertility, but there are several possible reasons why it occurs.
Assessment aims to confirm the diagnosis and determine whether sperm production is present. This may include repeat semen analysis, examination, hormone testing and selected genetic or imaging investigations.
Finding the cause is the first step toward understanding your fertility options.
What Causes Azoospermia
Azoospermia is broadly divided into two types: Obstructive and Non-Obstructive. Distinguishing between these two forms is important because azoospermia treatment differs significantly depending on the cause.
Non-Obstructive Azoospermia
Sperm production within the testes is significantly reduced or absent. Hormonal, genetic and testicular causes may contribute.
Obstructive Azoospermia
Sperm are being produced but cannot reach the ejaculate because of a blockage. Causes can include previous vasectomy, surgery or congenital abnormalities.
Treatment Options for Azoospermia
Treatment is personalised according to the cause of azoospermia and your fertility goals.
Options may include:
Microsurgical reconstruction for selected blockages
Surgical sperm retrieval for obstructive azoospermia
Micro-TESE for selected men with non-obstructive azoospermia
Hormonal treatment when an endocrine cause is identified
Coordination with IVF and ICSI where appropriate
If you have been told there are no sperm in your semen, specialist male fertility assessment can help clarify the diagnosis and available options.
