TESA (Testicular Sperm Aspiration)

What is TESA?

Testicular Sperm Aspiration (TESA) is a minimally invasive procedure used to retrieve sperm directly from the testicles in men with severe male infertility, particularly those with azoospermia (absence of sperm in the ejaculate). It is commonly performed in cases where sperm cannot be obtained naturally and is often used in combination with IVF (In Vitro Fertilization) or ICSI (Intracytoplasmic Sperm Injection).

When TESA is Recommended?

TESA is typically recommended in the following cases:

Obstructive Azoospermia (caused by blockages in the reproductive tract).
Non-Obstructive Azoospermia (due to poor sperm production).
Failed Sperm Retrieval in Ejaculate (due to medical conditions like retrograde ejaculation).
Prior Vasectomy (TESA can retrieve sperm without vasectomy reversal).

Steps Involved in TESA Treatment

Preparation: The procedure is usually performed under local anesthesia to numb the area.
Needle Aspiration: A fine needle is inserted into the testicle to extract a small tissue sample.
Sperm Extraction: The retrieved sample is processed in a laboratory to isolate viable sperm.
Fertilization: If sperm are found, they are used for ICSI, where a single sperm is injected directly into an egg.
