Surgical Sperm Retrieval (PESA/TESE)
About one man in a hundred produces no sperm or very few sperm
in his semen - a condition known as azoospermia and
oligoospermia. Various factors can contribute towards these
conditions, for example:
- Vasectomy (the male sterilisation operation).
- Illness (eg, mumps in adolescence).
- Trauma or injury to his groin.
- A genetic condition.
For some of these men it may be possible to surgically retrieve
sufficient sperm directly from the testes for use in the ICSI
procedure. This procedure is known as Surgical Sperm
SSR is usually planned in advance but in exceptional
circumstances can also be carried out as an emergency procedure if
the man is unable to produce a sperm sample on the day of his
partner's egg collection.
