When is TESA recommended for male infertility?

Testicular Sperm Aspiration (TESA) is recommended when there is a complete absence of sperm in the ejaculate, a condition known as azoospermia. Various factors can result in this condition, including blockages in the reproductive pathway or a lack of sperm production. TESA is also favourable in cases where previous attempts at sperm retrieval, such as PESA or TESE, have been unsuccessful.
