Abstract

The injection of spermatid cells into the human oocyte has been shown recently to result in normal fertilization and embryo development. In our study, fertilization and pregnancy rates of 23 non-obstructive azoospermic cases with severe spermatogenetic defect in their testicular biopsy are presented. Only the round spermatids in testicular samples could be found in 20 cases, but also elongated spermatids were found in 3 cases.
