Couples who are trying to conceive now have even more reason to have sex...every day.

Daily sex, in fact, improves the quality and health of men's sperm, according to new research by Dr. David Greening of Sydney, Australia. Of 118 men with above-average sperm DNA damage, the research found that the quality of sperm increased significantly after the men were told to ejaculate daily for seven days.

Greening stated that the higher sperm quality is likely due to the sperm's decreased exposure to potentially damaging molecules in the testicular ducts. "It seems safe to conclude that couples with relatively normal semen parameters should have sex daily for up to a week before the ovulation date," he said.

Based on this research, couples trying to conceive should no longer abstain from sex as ovulation nears--as was commonly debated among doctors and couples.
