TESA/PESA

Unique offer only for AMS patients
Special prices. Individual approach. Urgent treatment plan.

In complex cases of fertility disorders in men, including when it is impossible to obtain the ejaculate necessary for fertilization in a natural way, since it simply does not have viable sperm, two methods are used:

TESA - a method of percutaneous aspiration biopsy of the testicle in a man;

PESA is a similar biopsy method, but from an epididymis.

The effectiveness of both methods is confirmed by experience in many countries.


The indications for treating male infertility using TESA or PESA are:

  • defects identified by spermograms (low sperm count, low mobility, or a combination of both pathologies);
  • teratozoospermia (a high percentage of abnormal sperm in the ejaculate);
  • antispermal bodies in seminal fluid;
  • the absence of sperm in the ejaculate;
  • when the cause of infertility has not been established (idiopathic infertility).
