Patient's question:
Hello! How can I have a boy?Doctor's answer:
Humans have a total of 23 pairs of chromosomes, with 22 pairs being autosomes and the other pair being sex chromosomes. The sex chromosome karyotype of females is XX, while that of males is XY. If a sperm carrying an X chromosome fertilizes a female egg, the sex of the fetus will be female; whereas if a sperm carrying a Y chromosome fertilizes a female egg, the sex of the fetus will be male. The number of sperm carrying the X chromosome is the same as that carrying the Y chromosome in males, and the combination of male sperm with female eggs is random, ensuring a balanced sex ratio in human society. If the number of Y sperm is higher within a given time frame, the likelihood of giving birth to a boy naturally will be greater.
