When there is no sperm in the Ejaculate-semen, these minor procedures recover sperm directly from the testes or epididymis — so your own sperm can still be used with ICSI.

Surgical sperm retrieval is a group of minor procedures that collect sperm directly from the male reproductive tract when none can be obtained from the Ejaculate-semen — most often in azoospermia. The recovered sperm are then used to fertilise eggs through ICSI.
The right technique depends on the cause. PESA and TESA use a fine needle; TESE takes a small tissue sample; and Micro-TESE uses an operating microscope to find sperm in the most difficult, non-obstructive cases.

Mainly men with azoospermia, after a full evaluation.
A short procedure that can make a biological child possible.
Each technique targets a different cause of azoospermia — from a simple needle aspiration to microsurgery.
Hormone profile, examination and history confirm the azoospermia type and the best retrieval method.
PESA needle-aspirates sperm from the epididymis through the skin without any cut. It is used for obstructive cases like a prior vasectomy, infective block or absence of transport system from birth.
TESA needle-aspirates sperm from the testes through the skin without any cut. While in TESE a very small cut is made on testis to get more tissue to find sperm.
Micro-TESE systematically explores the entire testis under a microscope to identify best sperm-producing areas while preserving blood supply. Despite a larger incision, complication rates are similar to TESE, making it the best sperm retrieval technique for non-obstructive azoospermia (NOA).
A single viable sperm is injected directly into each egg with a fine needle — even a small surgically retrieved sample is enough for fertilisation.
Any sperm not used immediately are frozen and stored, so future ICSI cycles can go ahead without repeating the retrieval procedure.
Every fertility journey is unique. Surgical Sperm Retrieval success rates depend on several medical and lifestyle factors.
Factors affecting success
Retrieval rates are high in obstructive cases and more variable in non-obstructive ones; your surgeon will give a realistic, individualised estimate. Success cannot be guaranteed.

In some non-obstructive cases, no sperm are recovered despite microsurgery.
Temporary swelling, bruising or discomfort can follow the procedure.
Retrieval must align with the IVF cycle, or sperm are frozen.

It depends on the cause. PESA/TESA (needle) suit obstructive cases; TESE and Micro-TESE (microsurgery) are used for non-obstructive azoospermia. Your evaluation guides the choice.
Retrieval rates depend on various factors — the underlying cause, prior treatment and the technique used. As a general guide, sperm are found in approximately 40-60% of non-obstructive azoospermia cases, and 95%+ of obstructive azoospermia cases.
It is performed under anaesthesia, so it is not painful during the procedure. Mild soreness afterwards settles within a few days.
Microsurgical TESE uses an operating microscope to identify the tiny areas of active sperm production, giving the best chance of finding sperm in difficult cases.
Yes. Surplus sperm are frozen so future ICSI cycles do not need another procedure.
Yes. ICSI needs only a single viable sperm per egg, so surgically retrieved sperm work well for fertilisation.
