Surgical Sperm retrieval (TESA/MESA):
What is Surgical sperm retrieval?:
Surgical sperm retrieval may be necessary in men who have had any condition which blocks the passage of sperm from the testis to the urethra. This may include men who have had a vasectomy, men who have had previous trauma infection or inflammation to the area or in men who were born with altered anatomy.
Surgical retrieval involves a minor operation to remove fluid from the epididymis (a structure behind the testicle) with or without a small testicular biopsy. In severe cases of infertility a more extended biopsy of the testis is taken. All procedures are carried out under anaesthetic.
