Sperm Retrieval

When sperm cannot move through a man’s genital tract because of blockage, or if there is a mechanical problem with them getting to where they need to be, sperm retrieval from epididymis or testicular tissue can be an option.

Fertilisation is then attempted by placing the sperm and the egg together in the laboratory by the ICSI process.  There are different procedures for sperm retrieval, and your doctor will advise the best option for your circumstances.

A Testicular Sperm Aspiration (TESA) is a procedure where sperm is retrieved by a fine needle, which is passed through the skin of the scrotum, into the testes. The procedure is usually done under a general anaesthetic, depending on the anticipated difficulty in finding areas of reasonable sperm production.

A Microepididymal Sperm Aspiration (MESA) or Testicular Biopsy is a procedure where the scrotum is opened to expose the testis and its epididymis. The epididymis may then be surgically opened and its fluid aspirated to see if it contains live sperm, or a piece of testicular tissue may be surgically excised and passed to a scientist who dissects the tubules to look for live sperm.

A vasectomy reversal is possible, but it does not guarantee that your sperm will be of sufficient quality to achieve unassisted fertilisation and often the above techniques are preferentially recommended.
