Fathers can ALTER the sex of their children: Men who produce high-quality sperm are more likely to have sons

‘Dads can alter the sex of their offspring’, according to a Oxford University lecturer.

Men who produce high-quality sperm are more likely to have sons, new research reveals.

This comes after previous research suggests mothers have more influence over their offspring’s sex as experiencing the high physical costs of pregnancy makes them more likely to invest resources into determining their child’s gender. 

Past research also reveals sperm quality is affected by chemicals found in soap, sunscreen and plastic.

Lead author and lecturer Dr Aurelio Malo said: ‘In a nutshell, we now know that dads, as well as mums, can alter the sex of their offspring’.
