title: Ongoing pregnancies resulting from intracytoplasmic sperm injection (ICSI) of spermatozoa from frozen-thawed testicular biopsy specimens.
abstract: Two clinical pregnancies following intracytoplasmic sperm injection of spermatozoa from frozen-thawed testicular biopsies in two azoospermic men are reported. The use of spermatozoa from cryopreserved testicular tissue is therefore a viable option for azoospermic men, as our results indicate that pregnancies is achievable in these cases.
