While I prefer Dungeness or Blue Fin crabs to Oysters, I have heard they are a help to the libido. Looking up such theory on Health Line, I found the following conclusions.
The bottom line
Oysters are a good source of many nutrients that may help support sexual health.
In particular, the zinc in oysters may increase testosterone levels and help maintain healthy levels of dopamine. Their heart-healthy omega-3 fats may furthermore increase blood flow to prevent issues such as erectile dysfunction.
However, additional research is needed to understand whether eating oysters as part of a healthy, well-rounded diet directly increases libido and sexual function.
I see there is a need for reserachers. Perhaps this is your year to volunteer.
