Dr Roger Perkins
Am I a candidate for TESA?
Testicular Sperm Aspiration (TESA) is a technique to extract sperm from the testis with a needle. It is used in cases where men don’t have sperm in the ejaculate (azoospermia) caused by a blockage.
TESA for obstructive azoospermia
Who is TESA for?
"In these cases, the couple proceeds to needle extraction of sperm in order to fertilise eggs in vitro."
What if my azoospermia is not caused by a blockage?
"Micro TESE is a surgical procedure under full anaesthetic. We make a small incision in the scrotum and use a powerful microscope to search for active sperm."
About the TESA procedure
What does the procedure involve?
"That is a great advantage as the scientist provides immediate feedback on the sperm quality and quantity. We may extract more tissue to provide sufficient sperm for future in vitro cycles without having to repeat the TESA procedure."
TESA used for ICSI treatment
What happens after the sperm is collected?
"Most people know what IVF involves, but few have heard of ICSI (Intracytoplasmic Injection). The main difference between the two is how the eggs are fertilised. In IVF the egg and sperm (millions of sperm in the sample) are brought together in a petri dish to fertilise on their own. In ICSI, one sperm is injected into the egg. "
