During fertilization the sex of the child depends on whether the male gamete with X chromosome fertilizes the female gamete or the one with Y fuses with it. If the male gamete with X fuses with the female gamete it forms XX zygote that gives rise to a girl child. If Male gamete with Y fuses with the female gamete then XY zygote is formed which develops into a boy.
Thus scientifically it the male which decides the sex of the child and not the female. So it is not right to blame women for giving birth to the child.
