Testicular biopsy (TB)


The testicular biopsy is a little surgical procedure which is used to determine, in patients with infertility problems, whether there is sperm in the testis or not, or to diagnose if there is any genetic problem.

The technique consists in making a small incision in the testicle, in order to extract a small part of the testicle pulp to perform the study.

The procedure is done under local anesthesia and it is quick and easy.

If this procedure is done to diagnose the presence of sperm in the testicle and the diagnosis is confirmed, the sample will be frozen for a future In Vitro Treatment, which in this case will be the ICSI (Intracytoplasmatic Sperm Injection).


1) Azoospermia (complete absence of sperms): Either obstructive (sperm is produced but it can’t get out due to an ejaculatory duct obstruction), or secretory (there is no production of sperm).

2) Abort repetition

3) Genetic study
