A British study shows that men with high intelligence are more likely to have high-quality sperm This is the result of a British research team's analysis of data on some US veterans who participated in the Vietnam War The results showed that those who performed better on intelligence tests had more active sperm The study, published in the journal intelligence, seems to support a previous theory that genes that determine human intelligence also have an impact on other biological functions This means that any small change that impairs intelligence can do harm to other aspects of the gene, such as sperm quality In other words, people with healthy genes are more likely to have what biology calls "the strong factor", which makes people healthier, smarter and smarter In the past, scientists seem to be more inclined to think that lifestyle may reflect the relationship between intelligence and health For example, people with higher IQ prefer to exercise rather than smoke Both of them are known to have an impact on human brain activity The study involved 425 men All men underwent several intelligence tests and donated semen samples The researchers found that people with higher IQs performed better on three factors of sperm quality - quantity, concentration and mobility - regardless of age and lifestyle.
