While age is a significant factor in infertility for men and women – for men, semen quantity and sperm quality decline sharply after age 45, according to a recent study – there is still a lot that couples can do to alleviate their stress and optimize their chances of conceiving, according to natural fertility expert Dr. Lorne Brown. "Diet, for example, can have a real effect on women’s reproductive hormones. Research based on the Harvard Nurses Study found that women who followed a whole food, low GI, mostly plant-based diet experienced a six-fold increase in fertility."

"Women aren’t the only ones affected by diet," says Brown. "A recent study has shown that men who ate a high fat diet had a reduced sperm count and concentration of about 40% compared to men who had less fat intake."
