Impact of ejaculation frequency on semen parameters and DNA fragmentation: a cross-sectional study.
Plain-language summary

It looked at 1,349 men visiting a fertility clinic, grouping them by how often they reported ejaculating in the past month.

The study suggests that how often a man ejaculates may matter for fertility, separate from how long he waits between ejaculations.

- Higher ejaculation frequency was linked to lower sperm DNA fragmentation.
- More frequent ejaculation improved sperm vitality without negatively impacting motility.
