How long does it take to quit drinking to have children?

Patient's question:

Doctor, hello
My wife and I want to have a child now. I love drinking alcohol, how long do I need to abstain from alcohol? Additionally, 10 days ago, my wife took metronidazole for gingivitis. When is the best time for us to have a child? Thank you, doctor

Doctor's answer:

To have a healthy child (including growing up without alcoholism):
Generally, abstaining from alcohol refers to avoiding hard liquor, and it's important to stick to this for at least 2-3 months (as it takes 2-3 months for new sperm to regenerate). During this time, your partner can fully treat their periodontitis.
I think you should discuss this with your partner. When your mental, physical, financial, and environmental preparations are all in place, the spring season when everything blooms next year would be ideal.
Note: 1. Avoid excessive drinking during the Spring Festival; 2. Undergo a fertility check-up and evaluation at a formal specialized hospital.
