Increasing Male Fertility and Longevity
By Dr. Ed Rosick
The past 50 years have seen some amazing changes in the world. In 1953 a man who was 40 to 50 years old was already considered 'old' and well on his way to retirement. However, in 2003, being 40 isn't thought of by most (and especially those who have hit their fourth decade of life) as being old. It's now common to see 40-year-old men starting a 2nd or 3rd career, playing in professional sports or even being first-time fathers. Recent studies have indicated that the number of men aged 35 to 54 who are fathering children is up 20% in the past 20 years.
It's certainly heartening to realize that being past 40 doesn't mean a man can't enjoy the special pleasure of being a father. However, even in the 21st century, when the rules of aging are seemingly being rewritten on a daily basis, there are still some hard biological facts that all men must deal with. For those men who are trying to become a father, one of these facts is the decline in both the quality and the quantity of their sperm.
Infertility is not just a female 'problem'
Most couples will agree that one of the happiest times in their lives as husband and wife is when they first learn they're going to be parents. In fact, most couples take for granted their ability to have children and use birth control measures until they're ready to be parents. However, the truth is in the United States, at least 15% of all couples have great difficulty conceiving a child.1 While it's now known that in 30% to 40% of these cases this inability to conceive is due to male infertility, there is still a common misconception among both the lay population and the medical community that infertility is primarily a female 'problem.'
