Summary The aim of this work was to study the possible beneficial effect of repeated sequential ejaculation on sperm DNA integrity in subfertile males and its possible implementation in assisted reproduction. The study included 20 infertile males with idiopathic asthenozoospermia or oligoasthenozoospermia. They underwent detailed history taking, complete clinical assessment and hormonal assessment. Patients were asked to bring two semen samples (taken within 1–3 h). Two consecutive samples were assessed with regard to semen volume, sperm count, motility grading, and morphology and sperm DNA integrity using the comet assay. There was a significant improvement in the sperm motility pattern and DNA integrity in the second sample in comparison with the first sample. Therefore, it is concluded that due to its positive impact on sperm motility and DNA integrity, repeated sequential ejaculation is recommended in subfertile males with idiopathic asthenozoospermia who pursue assisted reproduction.
