If a woman does not become pregnant after treatment with medical and surgical techniques, she may choose to undergo more complex procedures, called ART, after consulting with her health care provider.
The Centers for Disease Control and Prevention compiles annual reports on the success rates of ART. These reports can be accessed at http://www.cdc.gov/art/ARTReports.htm.
Intrauterine insemination (pronounced IN-truh-YOO-ter-in in-sem-uh-NEY-shuhn) (IUI) is the placement of a man's sperm into a woman's uterus using a long, narrow tube.1
More information on IUI includes the following1:
During in vitro fertilization (IVF), eggs and sperm are taken from the couple and are incubated together in a dish in a laboratory to produce an embryo. A health care provider places the embryo into the woman's uterus, where it may implant and result in a successful pregnancy.
The steps of IVF are2:
In this process, also known as ovarian stimulation or ovulation induction, a woman takes medication to stimulate the ovaries to make many mature eggs at one time.
These medications are given by injection for 8 to 14 days. A health care provider closely monitors the development of the eggs using transvaginal ultrasound. Blood is drawn frequently to assess estrogen production by the ovaries. When the eggs are mature—as determined by the size of the ovarian follicles and the level of estrogen—an hCG injection initiates the ovulation process. A health care provider takes out (egg retrieval) the eggs 34 to 36 hours after the injection.
This is the process used to remove the eggs from the ovaries so they can be fertilized. The procedure is performed in a physician's office as an outpatient procedure. A mild sedative and painkiller are often used during the procedure, and it normally takes about 30 minutes. The steps for egg retrieval are:
A man provides a semen sample. If the sperm are healthy, they are placed in a dish with the egg and left overnight in an incubator. Fertilization usually occurs on its own. However, sometimes sperm are not able to fertilize the egg on their own. When this is the case, a single sperm is injected into an egg using a needle. This process is called intracytoplasmic (pronounced IN-truh-sahy-tuh-PLAZ-mick) sperm injection (ICSI). About 60% of IVF in the Unites States is performed with ICSI.3 The number of pregnancies from IVF using natural fertilization is about the same as the number resulting from ICSI.
Couples should consider genetic testing if the sperm cannot fertilize the egg on their own. The testing can determine whether the sperm have chromosome problems that might cause development problems in the resulting embryos.
Embryos that develop from IVF are placed into the uterus from 1 to 6 days after retrieval.
This procedure is performed in a physician's office. The procedure is normally painless, but some women may experience cramping.
A health care provider inserts a long, thin tube through the vagina and into the uterus and injects the embryo into the uterus. The embryo should implant into the lining of the uterus 6 to 10 days after retrieval.
When couples do not achieve pregnancy from infertility treatments or traditional ART, they may choose to use a third party assisted ART method to have a child.2 Assistance can consist of:
Couples can use donated sperm when a man does not produce sperm or produces very low numbers of sperm, or if he has a genetic disease. Donated sperm can be used with intrauterine insemination or with IVF.
This can be used when a woman does not produce healthy eggs that can be fertilized. An egg donor undergoes ovary stimulation and egg retrieval steps of IVF. The donated egg can then be fertilized by sperm from the woman's partner, and the resulting embryo is placed into the woman's uterus.
Egg donation may be particularly helpful2 for women who:
If a woman is unable to carry a pregnancy to term, she and her partner may choose a surrogate or gestational carrier.
A surrogate is a woman inseminated with sperm from the male partner of the couple. The resulting child will be biologically related to the surrogate and to the male partner. Surrogacy can be used when the female of the couple does not produce healthy eggs that can be fertilized.
In contrast, a gestational carrier is implanted with an embryo that is not biologically related to her. This alternative can be used when a woman produces healthy eggs but is unable to carry a pregnancy to term. If needed, egg or sperm donation can be used in this situation.
