Resumo
The application of assisted reproduction techniques has provided help to many men seeking to father a child, although the current success of these procedures remains suboptimal. Today some protocols allow sperm to be selected according to their ultrastructural morphology or surface molecular characteristics. On the other hand, successful human reproduction relies partly on the inherent integrity of sperm DNA. Therefore, it is now necessary to improve the safety of the sperm selection method. It is urgent to optimize procedures to isolate spermatozoa for ICSI with low risk of DNA damage. In recent years, two technologies have attracted the attention of specialists as methods capable of identifying a spermatozoon with low risk of DNA damage: Ultrastructural morphology sperm selection at high magnification and sperm head birefringence selection. This review analyses these two technologies. © Todos os direitos reservados a SBRA - Sociedade Brasileira de Reprodução Assistida.
