what does it consist of?
This consists of obtaining sperm directly from the testicles. It is a treatment for patients with an absence of sperm in the ejaculate or who have undergone a vasectomy.
Sperm can be extracted from the epididymis (narrow, elongated tube at the back of the testicle) or from the patient’s testicle using different surgical techniques.
- TESA (Testicular Sperm Aspiration): the testis is punctured with a needle and the spermatozoa are obtained by aspirating the fluid found inside the testicles.
- TESE (Testicular Sperm Extraction): an incision is made in the scrotum to obtain a sample of testicular tissue. From this sample, the specialist will obtain the spermatozoa necessary to carry out the treatment.
