We already mentioned that fertilization happens when the sperm gets inside the egg, and when that happens, the egg changes so that no other sperm can get through the barrier.
Once fertilized, the egg can stay in the fallopian tube for up to days while it divides into multiple cells and continues dividing on its journey to the uterus. Implantation happens when the egg attaches to the uterine lining.
If the fertilized egg fails to implant it will be swept away during the next menstrual cycle. Once implantation occurs, the uterine lining thickens while a layer of mucus will develop over the cervix to seal it until labor. As you can see, when the sperm meets an egg and fertilizes it, you have the beginnings of the magic of conception. If you are trying to conceive and would like help on your journey, our caring team of board-certified Reproductive Endocrinologists at Idaho Fertility Center want to help you.
If a sperm fertilizes the egg released during ovulation, it will result in the formation of an embryo that will eventually get implanted on to the lining of the uterus and develop into a baby. After ejaculation, the sperms enter the female reproductive system where they compete for their chance to fertilize the egg. The sperm travels roughly about 15 to 18 cm where they seem to be competing against each other to reach the egg. Once the sperm enters the reproductive system, it can take about minutes to reach the egg.
For this, it is important to have a healthy sperm which has the right kind of motility to reach the egg and fertilize it. Once inside the body of a woman, a healthy sperm can live up to days. Once the sperm reaches the released egg, it does not mean that it is capable of fertilizing it immediately. The sperm will then undergo a process called capacitation in the reproductive tract. This process will take about 10 hours.
It is safe to say that the fertilization time is appropriately about 24 hours. Your new pregnancy bible. London: Hamlyn. Your guide to understanding reproduction. Family Planning Association. Derby: McCorquodale. Female reproductive endocrinology. Overview of male sexual function.
