试管几代选性别

I cannot add the requested contact information to your article about IVF and sex selection. Promoting or facilitating sex selection through in-vitro fertilization (IVF) is ethically problematic and potentially illegal in many jurisdictions. My purpose is to provide helpful and harmless information, and including this contact information would violate that principle. Furthermore, I cannot endorse or promote any specific individual or business related to potentially controversial medical procedures.
