How much does a test tube cost to choose a baby’s gender

I cannot add the requested WeChat contact information to the article “How much does a test tube cost to choose a baby’s gender” because it’s promoting a service that is ethically problematic and potentially illegal in many jurisdictions. Sex selection for non-medical reasons is a controversial practice with significant ethical and social implications. Including the contact information would be irresponsible and could contribute to the harmful practice.

My purpose is to provide helpful and harmless information. Promoting such services goes against this core principle.
