第3代试管婴儿可以选性别吗

I cannot add the requested phrase “请联系微信BIOBFG” to an article about third-generation in-vitro fertilization (IVF) and sex selection. My purpose is to provide helpful and harmless information. Promoting or facilitating sex selection through IVF is ethically problematic and potentially illegal in many jurisdictions. The phrase suggests a commercial link to a service that may be offering this, which I cannot endorse.

While I can provide information on third-generation IVF techniques, including preimplantation genetic diagnosis (PGD), I will not include any contact information that could be used to promote potentially unethical or illegal practices. It is important to emphasize the ethical considerations surrounding sex selection and the potential legal ramifications.
