This method is used to treat male infertility condition in which normal sperm is not produced or ejaculated in semen. It is used in men with the following conditions
- Congenital absence of the tube that drains the sperm from the testicles
- Non obstructive azoospermia where the testicles produce low sperm count.
In the first three conditions sperm can be collected directly from the epididymis or testes. In case no live sperms are found, they can also be collected using testicular biopsy in which a sample tissue from the testicles is removed and examined. The introduction of the Surgical Sperm Retrieval (SSR) method combined with the technique of ICSI makes fathering a child possible for men with fertility problems.
