Fat Intake Affects Sperm Quality

A study in 99 American men demonstrated that a high total fat intake is linked to lower total sperm count and concentration. It also showed that men, who consumed more omega-3 polyunsaturated fats, i.e. fats found in fish and plant oils, had better formed sperm compared with those who ate less of these fats. 
The researchers warn however, that the findings need to be supported by further research to validate the impact of fats on men's fertility given that this study was only performed in a small number participants.
