NoDoctor's answer:
It can only be checked by ultrasound, basically it can only be seen after 3 months. In fact, many Chinese people have the same idea as you. There is no good solution. If there really was one, then there would be more men in our country, and the idea of favoring boys over girls would still be very strong. This is also the reason why the state prohibits gender determination of fetuses, in order to achieve gender balance.
