TESA - testicular sperm aspiration
A direct option when sperm cells are not found in the semen.
TESA (Testicular Sperm Aspiration) is a method to retrieve sperm cells directly from the testicles when none are found in the semen sample. The procedure is always combined with ICSI.
When is TESA used?
TESA is relevant when:
- A man has azoospermia (no sperm cells in the semen sample), but the testicles still produce sperm cells.
- A man has been sterilised (vasectomy), but the testicles still produce sperm cells that do not reach the ejaculate.
TESA requires that the woman undergoes egg retrieval at the same time (as part of an IVF/ICSI process).
Safety and support throughout the process
We understand that a procedure on the male partner can create uncertainty. Our approach is respectful, informative, and caring – we walk you through the entire process and make sure you feel seen and safe.
Results and potential
TESA combined with ICSI is often the only solution when sperm cells cannot be found in the usual way. When the technique is successful, it can open the door to fertilisation and pregnancy, even in complex cases.
How a TESA process works
1. Timing in the cycle
TESA is typically performed on the same day as egg retrieval for the woman.
2. Minor surgery under local anaesthesia
Local anaesthesia, pain relief, and sedative medication are offered. A thin needle is inserted into the testicle and a small amount of tissue is aspirated. The procedure usually takes 15-30 minutes. Most men experience only mild discomfort.
3. Sperm extraction and ICSI
As only few sperm cells are usually retrieved, ICSI is always used to fertilise the eggs (one sperm cell is injected into each egg).
4. Recovery
The patient can leave the clinic after about an hour. There may be some soreness in the scrotum for a few days.

Frequently asked questions (FAQ)
The procedure takes place under local anaesthesia, and you can receive additional pain relief. Most people experience only discomfort rather than pain.
The procedure itself takes little time – often under 30 minutes.
If no usable sperm cells are retrieved, you may have pre-agreed to use donor sperm or choose not to use the eggs retrieved.
Yes – because TESA usually yields only a few sperm cells, we always use ICSI for fertilisation.
