There are a number of reasons why a man may have little or no sperm in his sample. Some have to do with genetic factors whilst others are related to previous illnesses.
For men where no sperm is found in a sample the first step is usually testing, most commonly with blood tests and an ultrasound to try and determine the cause. Following testing your doctor will discuss with you the pros and cons of surgical sperm retrieval and whether it is suitable for you. It can also be indicated for those with a high degree of fragmentation in their sperm DNA.
Surgical Sperm Retrieval is a technique for collecting sperm directly from a man’s testicles or epididymis. It is a procedure we carry out under sedation. It usually involves a small incision in the skin of the scrotum. It takes about 30 minutes.
