OBJECTIVE: To better study the effect of sperm deoxyribonucleic acid fragmentation (SDF) on intracytoplasmic sperm injection (ICSI) outcomes from an ovum donation program by assessing the cumulative live birth rates (CLBRs) per number of embryo transfers (ETs), embryos replaced (EmbR), and metaphase II (MII) oocytes required in consecutive treatments to achieve the first newborn.
DESIGN: A multicenter retrospective cohort study was conducted, and the Kaplan-Meier survival curves were generated to calculate the CLBR with regard to the SDF degree.
SETTING: Private university-affiliated in vitro fertilization centers.
PATIENT(S): Data from 864 couples using donated eggs and undergoing ICSI from 2000 to 2019 were analyzed. Sperm deoxyribonucleic acid fragmentation was measured using terminal deoxynucleotidyl transferase biotin dUTP nick end labeling assay on their ejaculated sperm.
INTERVENTION(S): None.
MAIN OUTCOME MEASURE(S): Live birth rate (LBR) per first ET and per all consecutive ETs within the same patient and CLBR per ET, per EmbR, and per MII oocyte used considering the SDF level.
RESULT(S): A total of 1,903 ICSI cycles were considered, encompassing 6,340 donated oocytes, 2,543 embryos, and 1,145 ETs. Comparing ≤15% SDF (low) with >15% SDF (high) or by 10% SDF ranges, the LBRs per first ET and per all ETs did not significantly differ. The Kaplan-Meier curves of the CLBR per ET, per EmbR, and per donor oocyte consumed were similar between the SDF groups evaluated.
CONCLUSION(S): Elevated SDF does not reduce the LBR or cumulative probability to obtain a child when calculated per ET, per EmbR, and per donated MII oocyte used in couples undergoing ICSI cycles.
