Answer:
Humans have 23 pairs of chromosomes out of which 22 are autosomes and the remaining single pair is sex chromosomes.
The gender of the offspring largely depends on what the Ova or egg cell (X chromosome) inherits from its father.
If the sperm carries the X chromosome then the XX duo is going to result in a female offspring whereas if the sperm carries Y chromosomes then the XY duo will result in a male offspring.
These sperms enter the ovaries and fertilize the ova or egg cells once they are deployed in the vagina during copulation and break in through the cervix and swim (using their motile bodies and tails) to the ovaries through the oviducts and fertilize it.
