What is Sperm aspiration?
It is able to aspire the sperm with a needle straight from the testicle or the structure next to the testicle which also contains sperm (vas deferens). Man is under sedation and the area of the procedure us numbed with local anesthesia. Subsequently a small needle is introduced to the testicle and sperm is aspirated. It may sound painful but no hard pain is associated with this procedure. The whole process takes about 30 minutes.
There are various techniques of aspiring and extracting sperm:
- PESA: Percutaneous Epididymal Sperm Aspiration
- TESA: Testicular Sperm Aspiration
- TESE: Testicular Sperm Extraction
Both PESA and TESA can be done simply in the clinics office. However TESE involves a small incision and a bit of a tissue is snipped from inside of the testicle and so it often has to be done in a hospital.
