Can I Still Have a Biological Child if I Have Azoospermia?
In some cases, yes.
Azoospermia means that no sperm are found in the semen. However, this does not always mean that the testicles are making no sperm at all.[1,2]
The key is to work out why the azoospermia has occurred.
What causes azoospermia?
There are two main types.
Obstructive azoospermia
Sperm are being made, but a blockage stops them reaching the semen.
Causes can include:
previous vasectomy
being born without part of the sperm-carrying tubes
previous infection or surgery
another blockage in the reproductive tract.[2,3]
In some men, surgery to repair the blockage or sperm retrieval for IVF may be possible.[3,4]
Non-obstructive azoospermia
In this situation, sperm production within the testicle is reduced.
Causes can include:
genetic conditions
previous undescended testes
testicular injury
some previous medical treatments
hormone problems.[2,3]
Should a zero sperm count be checked again?
Usually, yes.
Azoospermia is generally confirmed with repeat semen testing. Sometimes very small numbers of sperm are found when the sample is examined more closely.[1,3]
Use the Semen Analysis Interpreter
Can sperm still be found in the testicle?
Sometimes.
In men with non-obstructive azoospermia, small areas of the testicle may still produce sperm.
A procedure called microTESE uses an operating microscope to carefully search for these areas.[3,4]
If sperm are found, they may be used with IVF and ICSI.
Studies report sperm retrieval in roughly 40–50% of men with non-obstructive azoospermia overall, but the chance varies greatly depending on the underlying cause.[3,5]
This figure cannot predict an individual person's result, and finding sperm does not guarantee pregnancy or live birth.
Does a high FSH mean there is no chance?
No.
A high FSH can suggest that sperm production is reduced, but it cannot reliably tell whether small areas of sperm production are still present.[3,5]
For this reason, decisions about sperm retrieval should not usually be based on FSH alone.
Why might genetic testing be needed?
Genetic testing can sometimes explain why azoospermia has occurred and may affect treatment decisions.[3,6]
It can also identify genetic conditions that may have implications for future children.
What should I do next?
A specialist assessment will usually focus on:
confirming the semen result
working out whether the cause is a blockage or reduced sperm production
checking relevant hormones
considering genetic testing
discussing the fertility health of both partners
deciding whether surgery, sperm retrieval or assisted reproduction may be appropriate.
Take home message
Azoospermia does not automatically mean that having a biological child is impossible.
Some men have a blockage while still producing sperm. In others, sperm may sometimes be found directly within the testicle.
The most important question is:
“Why are there no sperm in my semen, and what options are available in my situation?”
A specialist male fertility assessment can help identify the cause and explain the available options and their limitations.
