According to the normal physiology of pregnancy, the two girls were unable to produce offspring. A human being develops from an initially fertilized egg cell, and to form a fertilized egg, both sperm and egg must be present. The two women were unable to form a fertilized egg because they only had eggs and were missing sperm. After the semen is ejaculated into the vagina, the sperm leaves the semen to pass through the cervical canal and the uterine cavity into the cavity of the fallopian tube, during which the sperm undergoes a number of biochemical reactions known as sperm capacitation. At the same time, the egg will be discharged from the ovary and meet the energized sperm in the fallopian tube, where the sperm again undergoes some biochemical reaction called acrosome reaction, and only the sperm that undergoes acrosome reaction can fuse with the secondary oocyte. The fertilized egg is formed in the fallopian tube, and the fertilized egg is then implanted in the endometrium. The embryo implants into the endometrium about 6-7 days after fertilization, a process known as implantation. At this point the embryo gradually differentiates and grows to fetal maturity in the uterus. Based on the current physiology of pregnancy, two women are unable to produce offspring. It is advisable to consult a fertility clinic as to whether assisted conception is permitted in our country.
