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 (ICSI).[1] The testicular sperm extraction process is recommended to men who are unable to produce sperm by ejaculation as a result azoospermia, such as caused by primary testicular failure, 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, although the association is not very substantial, having a sensitivity of 0.65 (95% confidence interval [CI]: 0.56–0.74) and a specificity of 0.83 (CI: 0.64–0.93) for prediction the presence of sperm in the testes in non-obstructive azoospermia.[2]
