TESA & TESE

Testicular sperm extraction (TESE) is the process of removing a small portion of tissue from the testicle under local anesthesia and extracting the few viable sperm cells present in that tissue for the purpose of intracytoplasmic sperm injection . The testicular sperm extraction process is recommended to men who are unable to produce sperm by ejaculation caused by congenital absence of the vas deferens or non-reconstructed vasectomy.

Intracytoplasmic sperm injection (ICSI) and testicular sperm extraction (TESE) have reduced the need for donor sperm.

Serum inhibin-B weakly indicates presence of sperm cells in the testes, raising chances for successfully achieving pregnancy through TESE.
