It would perhaps be worth beginning with a description of what in vitro fertilization actually is. The process begins with the woman being prescribed fertility medications in order to stimulate the production of eggs in the ovaries; the eggs are then retrieved by doctors. Then the man produces a sample of his sperm. The crucial step of the process is described by the American Pregnancy Association in the following way: "In a process called insemination, the sperm and eggs are mixed together and stored in a laboratory to encourage fertilization. The eggs are monitored to confirm that fertilization and cell division are taking place.
IVF Research Report Introduction: In Vitro Fertilisation (IVF) is a ‘test tube’ technique used for couples that are infertile and also women that decide to have a child through this process. The process of IVF starts with a course of hormonal therapy to stimulate the development of many follicles within the ovary. After this course has taken place, the follicles are collected as eggs and then fertilised in test tubes. Between two to five days in an incubator, the eggs that were fertilised create embryos, which a selected few are transferred into the vagina, up to the uterus. Other embryos are frozen in case of any failures with the first few embryos1.
After conception comes the process of fertilization, which is the process in which sperm cells must be present in the woman's reproductive tract at the time the egg enters the fallopian tube. This can happen in several ways. If the woman has intercourse with a man during the week preceding ovulation, then he may deposit semen (a fluid containing sperm cells) into the woman's vagina. Some of the sperm can make their way through the cervix (the opening of the uterus, located at the end of the vagina), into the uterus, and on up into the fallopian tubes. There, one of them may meet with the egg as it travels down one of the tubes toward the uterus.
The first step in IVF is stimulating the ovaries. This is done by injecting a Follicle Stimulating Hormone (FSH) to increase the number of eggs the woman produces. Once the eggs have matured, they are removed from the ovaries by putting a needle into the fluid filled sacs, which hold the eggs, and aspirating them out. Figure 1 – Egg removal The semen is then collected and put into a test tube, with the sperm that have poor motility being filtered out. The eggs are then inseminated with the sperm and cultured in a laboratory for 16-20 hours.
Ultrasound An ultrasound is a test that sends sound waves into the woman’s abdomen or vagina in order to create an image to observe how the fetus is developing within the womb (“Pregnancy Ultrasound,” n.d.). Some of the many names for an ultrasound include pregnancy ultrasound, babi, obstetric ultrasonography, and an obstetric sonogram. The ultrasound can be done in either a hospital, doctor’s office, or a clinic (“Pregnancy Ultrasound,” n.d.). An ultrasound can performed transabdominally or transvaginally. A transabdominal ultrasound is performed over the woman’s abdomen and usually takes about 30-60 minutes.
This is also known as making "test-tube babies" Ã˜ Artificial insemination by husband (AIH) is the process during which a husband's semen is inserted mechanically into the uterus of his wife. Ã˜ Artificial insemination by donor (AID) is the process that occurs when the semen of an anonymous sperm donor is inserted mechanically into the uterus of a woman. Ã˜ Egg donation occurs when a woman donates an egg that is then fertilised, using in-vitro fertilisation, with the semen of the husband of the woman into whose uterus the resulting embryo is transferred. Ã˜ Embryo donation is a process that requires both egg and semen to be donated. The egg is fertilised with the semen using in-vitro fertilisation, resulting in the formation of an embryo.

IVF can result in a pregnancy with more than on fetus. The fertilised embryos are developed in the laboratory over a period of two to five days, and then transferred to the woman’s uterus in a procedure called an embryo transfer. Freezing embryos gives more opportunities for a pregnancy for each hormone stimulation cycle and egg collection. In vitro fertilisation is a treatment for infertility or genetic problems. IVF may be an option to people that has Fallopian tube damage or blockage, which makes it difficult for an egg to be fertilised or for an embryo to travel to the uterus.
There are many different ways in which to treat Infertility. One of the most popular is In Vitro Fertilisation (IVF) in which egg cells are removed from the womans body, and are then fertilized outside of the womans womb using either the womans partner or a donors sperm. The fertilised egg (zygote) is then transfered back inside the woman's uterus, bypassing the fallopian tubes. This is used if the male has a low sperm count or low sperm mobility.
