Whether checking male chromosomes before pregnancy can tell the probability of giving birth to boys and girls during this period.

Can't find out, Hong Kong blood test can be done after pregnancy. People are composed of 23 pairs (i.e. 46 chromosomes). Among these 46 chromosomes, one wayward chromosome determines the sex of people, that is, chromosome (X/Y). The pairing of male XY chromosome gene and female XX chromosome gene will constitute the following two conditions: XY gene and XX gene. The XY gene means a boy, and the XX gene means a girl. I went to Hong Kong Kangning Medical for seven weeks last year and was born in the New Year this year.
