Sperm DNA fragmentation(SDF)has been linked with male infertility,and previous studies suggest that SDF can have negative influence on pregnancy outcomes with assisted *** performed a retrospective review of consecutive couples with a high SDF level that had intracytoplasmic sperm injection(ICSI)using testicular sperm(T-ICSI).We compared the T-ICSI outcomes to that of two control groups:87 couples with failed first ICSI cycle and who had a second ICSI cycle using ejaculated sperm(Ej-ICSI),and 48 consecutive couples with high sperm chromatin structure assay(SCSA)-defined SDF(>15%)that underwent an ICSI cycle using ejaculated sperm after one or more failed ICSI cycles(Ej-ICSI-high SDF).The mean number of oocytes that were retrieved and the total number of embryos were not different among the three *** mean number of transferred embryos in the T-ICSI group was higher than the Ej-ICSI group but not significantly different than the Ej-ICSI-high SDF group(1.4,1.2,and 1.3,respectively,P0.05).No significant difference was found in live birth rate when comparing T-ICSI to Ej-ICSI and Ej-ICSI-high SDF *** results suggest that pregnancy outcomes and live birth rates with T-ICSI are not significantly superior to Ej-ICSI in patients with an elevated SCSA-defined sperm DNA fragmentation and prior ICSI failure(s).
