  Daily sex helps to reduce sperm DNA damage and improve fertility Daily sex improves men's sperm quality by reducing the amount of DNA damage. "I thought that frequent ejaculation might be a physiological mechanism to improve sperm DNA damage, while maintaining semen levels within the normal, fertile range," explained Dr David Greening, specialist in reproductive endocrinology and infertility at Sydney IVF. To investigate this hypothesis, Dr Greening studied 118 men who had higher than normal sperm DNA damage as indicated by a DNA Fragmentation Index (DFI). The men were instructed to ejaculate daily for seven days. When the men's sperm was re-assessed on the seventh day DFI had dropped from 34% to 26%. Archives:
