Pregnancy and birth after intracytoplasmic sperm injection with totally immotile sperm recovered from the ejaculate.

Retrospective case report.


METHODS
University-based hospital.

Four couples in whom spermatozoa recovered from the ejaculate were totally immotile but presented normal vitality scores.


METHODS
Therapeutical IVF-ET attempts coupled with ICSI.


METHODS
Fertilization and pregnancy results after ICSI.


RESULTS
With random sperm injection, 19 of the 36 injected oocytes showed normal fertilization and cleavage. One of four patients had a twin pregnancy that resulted in birth of two healthy children.

In cases in which totally immotile ejaculated sperm present normal vitality scores, normal clinical outcomes can be achieved by using the usual random sperm selection during conventional ICSI.
