How long in advance should one prepare their body before planning to have a child?

Patient's question:

No

Doctor's answer:

Women should maintain a healthy body for 3 to 12 months before conception.
1. Be in a good mood
2. Enhance nutrition
3. Appropriately reduce sexual activity to allow more high-quality sperm to accumulate in the seminal vesicles
4. Avoid exposure to insecticides, carbon dioxide, and harmful substances such as cadmium, nickel, zinc, mercury, and lead. These harmful substances more severely affect men, increasing the risk of spontaneous abortion in their wives due to non-external force damage.
