It’s not quite the equivalent of the female biological clock—because men can influence it by behavior—but some men engage in a practice that lowers sperm count.
What would that be?
They eat too many fruits and vegetables, and not enough animal protein. That is to say, they are vegetarians.
Now, we all know that a very healthy diet tends to contribute to increased longevity, but apparently, a man who gains those extra years pays for it with his sperm count. Worse yet, the sperm vegetarian men are less mobile than those of their meat-eating comrades.
The Daily Telegraph reports on the latest study:
Vegetarians and vegans may be harming their chance of having children after a study found that men who do not eat meat have significantly reduced sperm counts.
Although a diet that is rich in fruit and vegetables can protect against many illnesses and can prolong life, it appears that it may also harm fertility.
Researchers at Loma Linda University Medical School, in southern California, embarked on a four-year project to find out how diets affect sperm.
The region has a high population of Seventh-Day Adventist Christians who believe that meat is impure and so are strict vegetarians.
Seventh-day Adventists live an average of 10 years longer than the American life expectancy of about 79 years and the researchers wanted to find out if their astonishing longevity might be linked to sperm quality.
However they found the opposite. Vegetarians and vegans had significantly lower sperm counts compared with meat eaters, 50 million sperm per ml compared with 70 million per ml.
They also had lower average sperm motility – the number of sperm which are active. Only one third of sperm were active for vegetarians and vegans compared with nearly 60 per cent for meat eaters.
If a man replaces T-bones with soy protein, he will pay a price.
Soy contains phyto-oestrogens which have similar properties to the female hormone oestrogen.
An alternative explanation comes to us from Harvard University:
Separate research from Harvard University also found that a diet high in fruit and vegetables may impact fertility because men are consuming high quantities of pesticides.
This news might make your day. It might cause you serious reflection. You might not care at all.
I report; you decide.
