Daily sex (or ejaculation) improves men's sperm quality by reducing the amount of DNA damage, according to a study.

Until now, there has been no consensus amongst fertility specialists as to whether or not men should refrain from sex for a few days before attempting to conceive with their partner.

Researchers studied more than 100 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, and no other treatment or lifestyle changes were suggested. Before they started, levels of DNA damage ranged between 15 percent and 98 percent DFI. When the men's sperm was re-assessed on the seventh day, 81 percent of the men had an average 12 percent decrease in their sperm DNA damage.
