For couples trying to conceive, they should have sex everyday. Aside from the obvious, a new study by Dr. David Greening of Sydney IVF, an Australian center for infertility and in vitro fertilization treatment, says daily sex improves the quality of the sperm. Dr. Greening studied 118 men with above-average damage to their sperm DNA. He found that after they ejaculated for seven consecutive days, the quality of sperm increased--dropping 8 percent in the amount of damaged sperm. His advice for those of you ready to do some baby making? "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 says.
