It is also important for men to eat foods rich in calcium, such as eggs, milk, beef, oysters, prawns and fish. These foods are rich in protein and calcium, and also contain a lot of zinc, which is very helpful for promoting sperm production. In order to ensure the health of sperm, men should abstain from bad habits during pregnancy, such as smoking, drinking and staying up late. They should form the habit of going to bed early and getting up early, and take part in aerobic exercise properly, which can effectively improve sperm vitality and improve the chances of pregnancy. Men should also pay attention to keep warm during pregnancy to avoid catching a cold, which can prevent diseases from adversely affecting sperm.

Whether a woman can conceive successfully and whether the fetus is healthy is not only related to the quality of women's eggs, but also related to the quality of men's sperm. Therefore, men should eat more foods that help improve sperm quality during pregnancy.

First of all, you should eat more foods with high content of protein and arginine, because protein is the main raw material for forming semen, and you can eat more lean meat, pig spinal cord, chickens and ducks, eggs, fish and shrimp, bean products and so on. Arginine is an essential ingredient to produce sperm, so you should eat more foods with high arginine content during pregnancy, such as eel, cuttlefish, sea cucumber and pig's trotters. Secondly, vitamins can provide raw materials for sperm, which is beneficial to the production of sperm and can also enhance the vitality of sperm, so eat more foods with high vitamin content, such as various fresh vegetables and fruits. Minerals and trace elements are also indispensable substances to ensure sperm quality, especially zinc. If it is lacking, it will lead to sperm scarcity and testicular atrophy. So eat more shellfish, such as oysters, oysters, crabs and so on. In addition, you need to eat more foods rich in sex hormones and calcium, such as sheep kidney, pig kidney, chicken liver, shrimp skin, egg yolk, dairy products, kelp and other foods.

It is best for men not to smoke and drink during pregnancy, not to stay up late, and not to take medicine indiscriminately. They should form regular living habits and ensure adequate sleep.
