Surgery under general anaesthetic in the surgical day centre by a urologist. 

  • The urologist will make a small incision in the testicle.
  • Small portions of tissue are removed.

An embryologist will examine the testicular tissue for sperm cells in the fertility lab. The gynaecologist will inform about the presence or absence of sperm cells. 

For an extensive discussion of the results you will get a new appointment a couple of weeks later.

    • It is normal for the area around the incision to be somewhat bruised and/or swollen. The degree of pain, discolouration and swelling can vary from one man to another.
  • Rest sufficiently the first days after the procedure. You won't be able to go to work for 2 to 3 days. 
  • It is best not to take a bath the first 2 days. Taking a shower is not a problem. 
  • The wound does not have to be desinfected and the dressing does not need to be replaced. 
  • You can remove the dressing after two days. 
  • If you are in too much pain, you can take a painkiller (type Ibuprofen®, Paracetamol®).

Contact a doctor if the wound becomes warm, red and highly sensitive, or if you're worried or in case of persistent pain.
