Oyster, also known as oyster, has always been considered to have the effects of tonifying kidney, strengthening yang and strengthening body, and modern research has also confirmed this view. Oysters are rich in zinc, which is the highest in all foods. Ordinary foods, such as rice, flour and other vegetarian foods, contain very little zinc, so if you just eat these vegetarian foods, it is easy to lack zinc in your body; Even meat foods such as eggs and pork contain several times more zinc than oysters. In addition to zinc, oysters also contain selenium, and both zinc and selenium have the effect of treating oligozoospermia.

It is found that zinc is very important for the development of reproductive organs and the improvement of sexual function, and the rich zinc in prostate and semen is beneficial to the survival and activity of sperm.
