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).

fertility Preservation in Premature Ovarian Insufficiency (POI) Secondary to FSH Receptor Gene (FSHR) Mutation: Is There a New Hope?

A 19 years old patient with primary amenorrhea was referred to our center. Based on discrepancy between high follicle stimulating hormone (FSH) level and normal ovarian reserve parameters, follicle stimulating hormone receptor (FSHR) mutation was screened. The patient was homozygous in exon 6 of the FSHR gene for the new variant c.479T > C and predicted to result in an aminoacid substitution ***160Thr. One year later, her anti-müllerian hormone (AMH) level inexplicably decreased. Oocyte vitrification was thus offered for fertility preservation. After 17 days of recombinant follicle stimulating hormone (recFSH) (900 IU daily), no follicular growth was seen and estradiol levels remained low. In vitro maturation (IVM) was then suggested. Ten oocytes were successfully vitrified.
