TESA, or Testicular Sperm Aspiration, is a procedure used to retrieve sperm directly from the testicles in cases of male infertility. It is most commonly performed when a man has a condition called azoospermia, where there is no sperm in the ejaculate. Azoospermia can be due to two main types:

1. Obstructive Azoospermia: This occurs when there is a blockage in the reproductive tract, preventing sperm from entering the ejaculate, even though sperm production in the testes is normal.

2. Non-Obstructive Azoospermia: This is due to impaired or low sperm production in the testes.

When TESA Is Done?

TESA is typically recommended when:

• A man has non-obstructive azoospermia, and other treatments like hormonal therapy have not been effective.

• In cases of obstructive azoospermia where surgical correction is not feasible or not desired.

• As part of an in vitro fertilization (IVF) cycle, where intracytoplasmic sperm injection (ICSI) will be performed. ICSI is a procedure in which a single sperm is injected directly into an egg, which is especially useful for male infertility.

Why TESA Is Done?

The primary goal of TESA is to retrieve viable sperm from the testicles for fertilization. By directly collecting sperm from the testes, doctors can bypass issues related to sperm transport and low sperm count, making conception possible for couples dealing with severe male infertility.
