Mini-swim-up: a new technique of sperm preparation for intracytoplasmic sperm injection.
OBJECTIVE
The male factor is nowadays one of the major problems in the treatment of infertility. New methods of assisted fertilization such as the intracytoplasmic sperm injection (ICSI) show better fertilization and pregnancy rates than classical IVF.


METHODS
In this study, we present a new technique of sperm preparation: the "mini-swim-up."


CONCLUSIONS
This technique, used in conjunction with the ICSI procedure, improves pregnancy and fertility rates in cases of severe oligoasthenoteratozoospermia.
