What does a womans fertilized egg look like
The female reproductive system provides several functions. The ovaries produce the egg cells, called the ova or oocytes. The oocytes are then transported to the fallopian tube where fertilization by a sperm may occur. The fertilized egg then moves to the uterus, where the uterine lining has thickened in response to the normal hormones of the reproductive cycle. Once in the uterus, the fertilized egg can implant into thickened uterine lining and continue to develop. If implantation does not take place, the uterine lining is shed as menstrual flow.SEE VIDEO BY TOPIC: Egg preservation an option for young women at risk for sub-fertility

How Pregnancy Happens
Click to talk to a trained teen volunteer. Pregnancy is both simple and very complicated. Have you ever wondered exactly how pregnancy happens? If so, the information below should help. Hormones associated with the menstrual cycle period cause eggs inside the ovaries to mature. Every 28 days or so, one mature egg is released from the ovary. This is called ovulation. After the egg is released, it moves into the fallopian tube where it stays for about 24 hours.
If the egg is not fertilized during that time, the egg disintegrates breaks down and menstruation your period begins days later. The mature egg is fertilized when it is joined with a sperm cell. Sperm is contained in the semen which travels up the vagina, through the cervix and uterus and into the fallopian tubes.
If an egg is less than 24 hours old, it can be fertilized by a sperm. Fertilization sometimes but rarely happens when semen has been ejaculated outside but near the entrance of the vagina. Implantation: The fertilized egg attaches to the lining of the uterus and pregnancy begins. Most eggs are fertilized by sperm while still in the fallopian tube. The fertilized egg then travels down the fallopian tube into the uterus.
This can take days. When the egg reaches the uterus, it may attach itself to the uterine lining the endometrium and pregnancy will begin. Many fertilized eggs are never implanted and are flushed out of the body with the next period. Quick Hide. How Pregnancy Happens Pregnancy is both simple and very complicated. How does pregnancy happen? Before pregnancy can begin, two important steps need to take place.

Female Reproductive System
Egg count is one factor in age-related fertility decline. The other—and most important—factor is egg quality. Egg quality refers to the state of an egg as genetically normal or abnormal. As you ovulate, they go through another phase of cell division, known as meiosis.
Pregnancy begins when a sperm fertilizes an egg. This usually occurs in the 2 weeks following the first day of the most recent menstrual period. In the first few weeks of pregnancy, a woman may have no symptoms. Some can sense that they are pregnant, but most do not suspect it until they miss the next period.
The answer comes down to the simple fact that high-quality eggs produce high-quality embryos, which must then be strong enough to survive the early stages of development in order to result in a successful pregnancy. With that being said, it's a lot easier said than done, and we realize that the "science" behind of egg and embryo quality may at times be a bit tricky to understand. That's why we've laid out a handful of common FAQ's to ensure you are knowledgeable and confident in the what we do "behind the scenes" in our laboratory.
