Every male has both y chromosome sperm and x chromosome sperm. However, some men may have deficiencies, but this situation is not very common and requires consistent treatment. So are there male sperm with only Y chromosome?
The situation where males only have Y chromosomes exists, but it is not very common. Only sperm on the Y chromosome is an important cause of early miscarriage in women. In addition to genetics, sperm chromosomes are also affected by infections or taking the wrong medication.
Under normal circumstances, both men and women have chromosomes 23, with one pair belonging to the sex chromosomes that determine the gender of future children.
Male chromosomes have x and y, while females only have xx type. If there is only y in male sperm, then the baby born can only be female. Only when there is an X chromosome in sperm can there be a possibility of giving birth to a female baby. The body belongs to a normal male, and the x and y chromosomes in sperm should be equal, so under normal circumstances, the probability of giving birth to boys and girls is the same.
If there are males with only y chromosomes in their sperm, they must pay attention. If they want to have a girl, they must go to the hospital for treatment. Find out the cause, but chromosomal deletions are generally incurable and mostly congenital.
