foods that give trans fat

not eating healthy food

The disease of azoospermia can also be caused by nutritional deficiency. Therefore, if you do not eat healthy food like pumpkin, zucchini, okra, jackfruit, soybean, then you are causing a lot of harm to the body. You should eat foods containing vitamins, minerals and fiber daily.
