If the egg is not fertilized or does not implant, the woman’s body sheds the egg and the endometrium. This shedding causes the bleeding in a woman’s menstrual period. When a fertilized egg does implant, a hormone called human chorionic gonadotropin (hCG) begins to be produced in the uterus.
What stops a fertilized egg from implanting?
Plan B acts primarily by stopping the release of an egg from the ovary (ovulation). It may prevent the union of sperm and egg (fertilization). If fertilization does occur, Plan B may prevent a fertilized egg from attaching to the womb (implantation).
Why am not getting pregnant when everything is normal?
There are many possible reasons, including ovulation irregularities, structural problems in the reproductive system, low sperm count, or an underlying medical problem. While infertility can have symptoms like irregular periods or severe menstrual cramps, the truth is that most causes of infertility are silent.
How often do fertilized eggs fail to implant?
Between one-third and one-half of all fertilized eggs never fully implant. A pregnancy is considered to be established only after implantation is complete.
What does sperm do while waiting for egg?
Only one sperm will succeed in penetrating the egg’s outer membrane. After the sperm penetrates the egg, the egg immediately undergoes a chemical reaction that prevents other sperm from penetrating. Chromosomes carried by the sperm and the egg then come together, and the egg is officially fertilized.

How long will sperm wait for an egg?
It takes about 24 hours for a sperm cell to fertilize an egg. When the sperm penetrates the egg, the surface of the egg changes so that no other sperm can enter. At the moment of fertilization, the baby’s genetic makeup is complete, including whether it’s a boy or girl.
