The Basics of In-Vitro-Baby
In vitro fertilization (IVF) is one of the more popular types of assisted reproductive technology. It uses a combination of medicines and surgical procedures to help sperm fertilize an egg and help the fertilized egg implant in your uterus.
IVF is most often used for couples with a history of infertility, but it can be helpful for women who are not having any luck getting pregnant on their own. In some cases, it can also be helpful for couples with known chromosomal abnormalities or other conditions that prevent them from having a baby. 시험관아기 시술
The success of IVF depends on many factors, including the woman’s age, the diagnosis of her fertility problems, the quality of her sperm and the response of her ovaries to medication. It is not uncommon for a couple to have a series of treatment cycles before they have a successful pregnancy.
During IVF, the woman’s ovaries are treated with hormone medications to stimulate egg production. These medications are given in a controlled environment and the results are monitored closely. The medications are typically very effective at increasing the number of eggs produced in a person’s ovaries.
Once the ovaries have a number of mature eggs, they are harvested. This is done by using a procedure called oocyte retrieval. The doctor places an ultrasound probe in the vagina and passes a thin needle along the guide into the ovary to locate follicles.
After the oocytes are retrieved, they are mixed with a sample of sperm. This can be your partner’s sperm or donor sperm. The sperm is then injected into the eggs using a procedure called intracytoplasmic sperm injection.
Fertilized eggs are placed in a special chamber and kept under observation until they become embryos. They are then transferred to the uterus through a tube that is placed in the cervix. Embryos are transferred at different stages, depending on the individual woman’s needs and preference.
A few days after the sperm is injected into the egg, the woman’s body starts growing an embryo inside the egg. The embryo may divide and begin to grow, or it may stay in the egg as a single cell. The process continues for several days until the embryo is ready to be transferred.
Before an embryo is transferred, a test is performed to see whether the embryo has a healthy chromosomal make-up and is not missing parts of its outer layer, or coating, that are necessary for proper development. Some fertility centers also perform preimplantation genetic testing, which screens an embryo for chromosomal abnormalities or other problems that might prevent it from being viable during pregnancy. 난임병원
Embryos that are considered good quality are transferred into the woman’s uterus through a tube placed in the cervix. The uterus is then surrounded by a lining of cells that prepare the uterine lining for the embryo to implant and start a pregnancy.
The number of embryos that are transferred will depend on a variety of factors, including the woman’s age and her desire for a baby. The American Society for Reproductive Medicine recommends that no more than two embryos be transferred in women under the age of 37, and no more than three in women 38 or older.
