Having sex every day improves the quality of men’s sperm and is recommended for couples trying to conceive, according to new research.

But a new study by D. Greening of Sydney IVF, an Australian centre for infertility treatment, suggest that abstinence is not the right approach. Men with above-average sperm DNA damage and found the quality of their sperm increased significantly after they were told to ejaculate daily for seven days. On average, their DNA fragmentation index – a measure of sperm damage – fell from 34% to 26%, he told the European Society of Human Reproduction and Embryology in Amsterdam.
