what does it consist of?
In patients with certain types of azoospermia, or who have previously undergone a vasectomy, a sufficient amount of sperm cannot be found in a semen sample to perform an assisted reproduction treatment. In these cases, sperm recovery techniques allow to recover a sperm sample directly from the testicles.
- TESA (Testicular sperm aspiration): fluid containing the sperm is aspirated from the testes using a needle.
- TESE (Testicular sperm extraction): if the previous techniques have been ineffective, a biopsy of the testicle will be needed. To do this, an incision will be made in the scrotum and a portion of testicular tissue will be removed, which will contain the sperm.
who is it for?
Patients who have undergone a vasectomy
Patients with obstructive azoospermia (male whom produce sperm, however there is absence of spermatozoa in ejaculate)
Men with cystic fibrosis
