What is FNA biopsy?

Fine-needle aspiration biopsy (FNA) of the testicle is a procedure used to obtain sperm directly from the testicle. These collected sperm will be used in an in vitro fertilization (IVF) treatment or can be frozen for future use.

This technique is usually used in those men who are diagnosed with azoospermia, that is, absence of sperm in the ejaculate. In addition, testicular FNA is also common for patients who have vasectomy and do not want to do a reversal of it.

Therefore, testicular FNA is a successful and non-aggressive technique for men, so it can be carried out on several occasions if necessary.
