[The value of fertilization in vitro and derived technics in oligo-astheno-teratospermia].

The authors report the advantage of fertilization in vitro and ancillary techniques in hypofertility by male component. In their fertilization in vitro program, a male indication is individually found in 10% of the cases, but also in female indications, even those of tubal origin. In summary, sperm anomalies are reported in 25% of couples entering a program of fertilization in vitro. Therefore they explain their current approach toward one or two cycles of diagnostic FIV, and then propose the most appropriate technique of assisted procreation for each case.
