[Artificial insemination with donor frozen sperm].

The cryopreservation of human sperm decreases its fecondity, by reduction in the number of motile sperm. However the fertilizing ability of the spermatozoa is not faded. The use of frozen sperm requires an optimization of the methods of artificial insemination to hope to approach the results obtained with fresh sperm. Intrauterine insemination with sperm selection meets this aim.
