As eggs mature, they go through stages of chromosomal division. These stages result in a reduction in their chromosome number by one half. The extra chromosomes are contained in a small, round body located on the side of the egg.

This is called a polar body. If an egg does not have a polar body at the time of the fertilization check it is still immature and not ready for a sperm to fertilize it.

Also, if it has not formed a polar body by this time twenty four hours after the egg retrieval , it is defective and will not be capable of fertilization at a later time. This can happen if the egg is defective in its number of chromosomes and does not have a complete plan for building an embryo.

This results in the egg being incapable of further development. The sperm can also be the cause of a mature egg not fertilizing.

This is often associated with a high percentage of abnormally shaped sperm. In severe cases, this may result in total failure of fertilization.

If this is suspected, intra-cytoplasmic sperm injection can be used to overcome this penetration problem. If the problem with the sperm is chromosomal in nature, fertilization can fail because the sperm does not have a complete plan for building an embryo.

In this case, it will not matter if the sperm penetrates the egg, because it cannot form a pronucleus. The egg will not fertilize and it will prevent any further development. Unfortunately in these cases, intra-cytoplasmic sperm injection cannot overcome the problem. There are some eggs that are in the ovaries that have no chance of developing into an embryo because they are atretic.

Atresia is a form of abnormal development in which the cytoplasm, or cell material, of the egg is dark and non-functional. Just as there are sperm that have abnormal morphology and are not functional, so too there are eggs that are abnormal from the moment of their development and have no potential for growth. These eggs often break during the aspiration process that is necessary to remove them from their follicle. The result is an egg that loses its shell or one in which the cell material, or cytoplasm, also breaks.

Without the protective shell at this early stage, the egg cannot survive and grow normally. If these eggs with weakened shells had not been aspirated, but had been allowed to ovulate and enter the Fallopian tube, the result would likely be the same.

They would not have survived the fertilization process in the body and would not have developed a normal embryo without the protection of an intact, strong shell. No Fertilization. At fertilization check, the embryologist usually sees that some of the eggs have no fertilization. Eggs fail to fertilize for a variety of reasons.

The embryologist may see that some of the eggs are immature. There are some eggs that have a polar body present but are still not fertilized.

Some eggs have perfectly healthy chromosomes and cytoplasm but may have a poorly formed shell, or zona pellucida. Created By : Catalyst Healthcare Marketing.

How Pregnancy Happens - Teen Health Source

There are many misconceptions about fertilization and pregnancy. While fertilization can seem like a complicated process, understanding it can equip you with knowledge about your own reproductive system and empower you to make decisions.

Fertilization takes place in the fallopian tubes , which connect the ovaries to the uterus. Fertilization happens when a sperm cell successfully meets an egg cell in the fallopian tube. Once fertilization takes place, this newly fertilized cell is called a zygote. From here, the zygote will move down the fallopian tube and into the uterus. The zygote then burrows into the uterus lining.

This is called implantation. An exception to this rule would happen with in vitro fertilization IVF. In this case, eggs are fertilized in a lab. Ovulation is when a mature egg is released from one of your ovaries. There are a number of reasons why fertilization might not happen.

This includes use of contraception and infertility. Usually, only one egg is released during ovulation. However, the ovaries sometimes release two eggs at once. In this case, you might become pregnant with twins. These twins will be known as fraternal twins also called nonidentical twins. Fertility treatments like IVF can increase the likelihood of multiple births , according to Cleveland Clinic.

This is because fertility treatments often involve transferring more than one embryo to the uterus at a time to increase the chances of pregnancy. Fertility drugs can also result in more than one egg being released during ovulation.

Because both cells come from the exact same egg cell and sperm cell, identical twins will have the same DNA, the same sex, and a nearly identical appearance. At the point of ovulation, the uterus wall is thick. The American College of Obstetrics and Gynecology ACOG considers someone pregnant only once the embryo is successfully implanted against the uterine wall. In other words, implantation marks the beginning of a pregnancy.

The embryo, however, might not implant. Emergency contraception , intrauterine devices IUDs , and infertility could prevent the embryo from implanting.

In the event that ovulation has already occurred when you take Plan B, the U. Food and Drug Administration notes that it may prevent a fertilized egg from implanting. An IUD works by thickening cervical mucus.

This can both prevent ovulation and create an environment that kills or immobilizes sperm, preventing the possibility of fertilization. Rather, they prevent pregnancy from happening.

IUDs and emergency contraceptive pills are both extremely effective forms of contraception. According to the World Health Organization , both are 99 percent effective at avoiding pregnancy. About 90 percent of ectopic pregnancies occur when the embryo implants in one of the fallopian tubes. It could also attach to the cervix or abdominal cavity. Ectopic pregnancies are medical emergencies that need prompt treatment to prevent a tube rupture.

After implantation occurs, the placenta forms. At this point, your body will produce the hormone human chorionic gonadotropin hCG. According to Mayo Clinic , hCG levels should double every two to three days in the early stages of pregnancy.

Pregnancy tests work by detecting hCG in your body. You can either test your urine, as with home pregnancy tests, or test your blood via your healthcare provider. This will make it easier for the test to measure your hCG levels. Most babies are born in week 39 or Week 1 is actually retroactively counted from the first day of your last period. The difference between an embryo and a fetus is gestational age.

Until the end of week 8 of pregnancy, the fertilized egg is called an embryo. At this point, all major organs have begun to develop, and the placenta is taking over many of the processes such as hormone production. Knowing about reproduction can help you get pregnant, make better decisions about contraception, and understand your own body better. Many different factors affect your chances of getting pregnant.
