How fertile is your man? If you want to find out, count how many brothers he has, researchers suggest. According to a new study, the greater the number of male siblings your partner has, the more fertile he is likely to be.
They have discovered that men with more brothers than sisters are likely to be more productive, the Daily Mail reported. The travelling speed of the sperm from 500 men were assessed and compared with their family make-up by scientists from the University of Sheffield.
According to Dr Allan Pacey, one of the researchers from the University of Sheffield, they found that the greater number of brothers, rather than sisters a man has, the faster his sperm is, increasing the likelihood of fertility. The findings published in the Asian Journal of Andrology, also back the theory that parents with good male fertility genes are more likely to have boys. Lots of brothers is also an indication that the man's parents have strong male fertility genes, and they would then be passed on to the son, Dr Pacey added.
Though the research did not give any clues as to how to treat male infertility, the surprising results could provide genetic insights into why some men are more fertile than others, said Dr Pacey. According to him it does, however, give food for thought about the importance of genetics for sperm motility and may open the way to more studies in this area. Sperm motility is a major factor in male fertility.
