Pregnancy after Intracytoplasmic Injection of Sperm Obtained from Testicular Sperm Extraction : The First Case Report in Thailand

Abstract

Here we report a case in which fertilization and pregnancy was achieved after intracytoplasmic sperm injection (ICSI) of testicular sperm in an azoospermic patient with minimal spermatogenesis and maturation arrest. Eight oocytes fertilized normally out of 10 injected. Four pronuclear stage embryos were transferred into the fallopian tubes and the others were cryopreserved. Despite using nearly immotile sperm, pregnancy was still possible. So in association of ICSI and testicular sperm extraction (TESE) most cases of azoospermic patient can now be successfully treated.
