There may be something to that myth about oysters and sex drive after all. Couples who eat a lot of seafood have sex more often and are quicker to achieve a pregnancy, new research has shown.

The findings may be partly explained by the effects on semen quality, ovulation and embryo development, scientists believe.

Audrey Gaskins, one of the researchers from the Harvard TH Chan School of Public Health, in Boston, US, said: "Our study found that couples who consume more than two servings of seafood per week while trying to get pregnant, had a significantly higher frequency of sexual intercourse and shorter time to pregnancy."

The scientists tracked the dietary habits of 500 couples for one year to determine the relationship between seafood consumption and time to pregnancy.

All the participants were enrolled into the Longitudinal Investigation of Fertility and Environment (Life) study that was looking at environmental influences on birth success.

Diary

They were asked to keep a diary recording their daily seafood intake and sexual activity.

The findings showed that 92pc of couples who ate seafood more than twice a week achieved a pregnancy at the end of one year, compared with 79pc of those consuming less seafood.

The association between seafood consumption and faster time to pregnancy could not be completely explained by more frequent sex, said Ms Gaskins.

Other biological factors linked to the beneficial effects of seafood were also thought to be at play, she said.

"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," Ms Gaskins added.

The research is reported in the 'Journal of Clinical Endocrinology & Metabolism', published by the Endocrine Society.
