The study, which reviewed 40 years of research on the effect of parental age on fertility, pregnancy and the health of children, was published in the journal Maturitas. While the medical profession has no clearly accepted definition of when advanced paternal age begins -- it ranges from 35 to 45 -- infants born to fathers over 45 have risen 10 percent in the United States over the past 40 years, likely due to assisted reproductive technology.

Women face the brunt of societal pressure to have children before a certain age, but a new study concludes that the so-called biological clock is a concern for men, too. The authors suggest that more men may want to consider banking their sperm if they intend to wait until later in life to start a family. The paper, published in the journal Maturitas, is a review of the medical literature on older fathers, defined as starting between the ages 35 and 45, depending on which researchers you ask. It highlights studies showing a variety of increased health risks incurred by the partners and children of these older dads.
