Couples who eat seafood more than twice a week have more sex and get pregnant quicker, a study of 1000 people has found.

The study tracked the dietary habits of 500 couples who were trying to get pregnant over the course of a year.

By the end of the year, 92 per cent of those who ate more than two portions of seafood a week had achieved a pregnancy. Of those consuming less seafood, 79 per cent of couples were successful.


The couples who ate a lot of seafood reported having sex more frequently, but this did not fully explain the shorter time to pregnancy, suggesting that seafood may boost fertility in some other way.

“Our results stress the importance of not only female, but also male diet on time to pregnancy, and suggests that both partners should be incorporating more seafood into their diets for the maximum fertility benefit,” says Audrey Gaskins, of the Harvard TH Chan School of Public Health.
