[Pregnancies after in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) of testicular spermatozoa (TESE) from frozen semen].

This case report describes the possibility of establishing intact pregnancies by using cryopreserved testicular sperm for in-vitro-fertilization (IVF) with intracytoplasmatic sperm injection (ICSI). Because of a bilateral postinflammatory occlusion of the ductus deferens the patient underwent two cycles of IVF without ICSI by using epididymal sperm (MESA), however no fertilization occurred. In a third attempt with ICSI we used testicular sperm (TESE), because epididymal sperm was not detectable any longer.
