My wife says oysters are rich in zinc, good for male physiology, and eating a lot increases the chances of conceiving a boy. Is this true? (Tung, 30, Hanoi).
For over a month, my wife has been supplementing my diet with raw oysters, grilled oysters, and oyster soup to improve premature ejaculation, but I still lack interest. Why is this, and do I need a medical examination? (Minh, 39, Hanoi)
