What should men pay attention to when they want to have children?

Patient's question:

No

Doctor's answer:

Do not take medicine indiscriminately, maintain a reasonable nutritional balance, get adequate rest, and of course, the man should quit smoking and drinking. Girls should also be cautious about hair dyeing and the use of cosmetics. Everything else should be left natural. There is no need to add other health supplements, as current health supplements can actually be harmful to the fetus.
