Abstract:

Objective

To study how the choice of the first assisted reproductive technology treatment type affects the cumulative live birth rate (CLBR) in couples with high sperm DNA fragmentation index (DFI).


Design

Longitudinal cohort study.


Setting

University-affiliated fertility clinic.


Patient(s)

A total of 2,713 infertile couples who underwent assisted reproductive technology treatment between 2007 and 2017 were included in the study. All in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) treatments (up to three fresh treatments and all associated frozen-thawed embryo transfers) offered to the couples by the public health care system were included, in total 5,422 cycles.


Intervention(s)

None.


Main Outcome Measure(s)

The primary outcome was the CLBR. The secondary outcomes were the fertilization rate and the miscarriage rate. The IVF and ICSI groups were defined according to the method applied in the first treatment cycle.


Result(s)

In the IVF group, the CLBR values were higher for couples with normal DFI compared with those for couples with high DFI (≥20%) (48.1% vs. 41.6% for conservative CLBR estimate and 55.6% vs. 51.4% for optimal CLBR estimate after adjustment for female age, respectively). No DFI-dependent difference was seen in the ICSI group.


Conclusion(s)

Our results demonstrated that a high DFI predicts a statistically significantly lower CLBR if IVF and not ICSI is applied in the first cycle of assisted reproduction.
