Adding more seafood to the diet could help get couples' sex lives, and even their fertility, back in the swim of things, new research shows.
The study couldn't prove cause and effect, but couples who ate more fish each week were more likely to conceive children during the year of the study.
"Our study suggests seafood can have many reproductive benefits, including shorter time to pregnancy and more frequent sexual activity," said study author Audrey Gaskins, from the Harvard T.H. Chan School of Public Health in Boston.
The new research was funded by the U.S. National Institutes of Health. For the study, Harvard researchers tracked outcomes for 500 couples in Michigan and Texas for one year. All of the couples were planning a pregnancy, and the couples recorded the amount of seafood they ate and kept daily journals of their sexual activity.
The findings showed that couples who ate seafood more than twice each week had sex more often -- an average of 22 percent more frequently than couples who consumed less fish.
Also, 92 percent of the couples who ate seafood more than twice each week were expecting a child by the end of the study, compared to 79 percent of the couples who ate seafood less often, according to the report.
The researchers noted this link between seafood intake and pregnancy couldn't be explained solely by more frequent sex the couples were having. That suggests that seafood intake might affect semen quality, ovulation or embryo quality.
"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," Gaskins said in a news release from The Endocrine Society.
Dr. Tomer Singer directs reproductive endocrinology and infertility at Lenox Hill Hospital in New York City. He wasn't involved in the new study, and stressed that a cause-and-effect relationship isn't clear.
It's uncertain "if these couples benefit from the actual ingredients found in seafood," Singer said. Maybe "these findings were coincidental and these couples were actually healthier, ate a healthier diet in general or had more 'sushi night' dates," he reasoned.
