It turns out, that oyster aphrodisiac myth not be a myth at all. You may have heard that they'll get you in the mood because oysters are high in zinc, which is linked to high testosterone levels in rats. I've also heard it's because eating an oyster is similar to giving oral sex to a woman, which I don't understand because I've definitely never done that in a Red Lobster. But as far as oysters leading to sex is concerned, there may be science to back this idea up.
New research from Harvard T.H. Chan School of Public Health, which looked at data of 501 couples who were trying to get pregnant, shows that eating seafood is linked to having more sex — and higher pregnancy rates. They study went on for four years, where couples were each followed for one year or until pregnancy was detected. And the results were clear — more seafood intake was associated with having more sex and fecundity — which essentially just means fertility or the ability to produce offspring. Say it with me: fecundity. More seafood, higher fecundity.
Basically, the research found that 92 percent of the couples who ate fish and shellfish at least twice a week were able to get pregnant within the year. They also found that those who ate the most fish and shellfish — to the tune of eight or more times a month — had a 22 percent higher rate of sexual activity than average. So if you're trying to get pregnant — or just have more sex life — you may want to pass the lobster.
The researchers actually didn't set out to prove the link between seafood and sexual intercourse, so the results were a shock to them too. "We are not sure what exactly is driving this association," Audrey J. Gaskins, Sc.D., Research Associate at the T.H. Chan School of Public Health, tells Bustle. "For example, the original reason why shellfish such as oysters were linked to increased libido was due to their high zinc content. Studies have shown that in humans, dietary zinc intake has a positive correlation with testosterone levels and in rats that zinc therapy improves sexual competence. However, given that we did not measure zinc intake in our study and zinc is found in many other foods other than seafood, we felt uncomfortable making this link in our study."
Gaskin also says there's a possible behavioral explanation for the link. "It is also possible that couples who consume higher amounts of seafood together share more meals and thus more time together (including nights) which may be a behavioral explanation for the association we observed with sexual activity," she says.
So now you know. But it's not the first time a link between food and sex has been proven. Take a look at some of the connections below.
