    What is involved in in vitro fertilization? What is involved with in vitro fertilization? There are basically 5 steps in the IVF and embryo transfer process which include the following: 1. Monitor and stimulate the development of healthy egg(s) in the ovaries. 2. Collect the eggs. 3. Secure the sperm. 4. Combine the eggs and sperm together in the laboratory and provide the appropriate environment for fertilization and early embryo growth. 5. Transfer embryos into the uterus. Step 1: Fertility medications are prescribed to control the timing of the egg ripening and to increase the chance of collecting multiple eggs during one of the woman's cycles. This is often referred to as ovulation induction. Multiple eggs are desired because some eggs won’t develop or fertilize after retrieval. Egg development is monitored using ultrasound to examine the ovaries and urine or blood test samples to check hormone levels. Step 2: Your eggs are retrieved through a minor surgical procedure which uses ultrasound imaging to guide a hollow needle through the pelvic cavity. Sedation and local anesthesia are provided to remove any discomfort that you might experience. The eggs are removed from the ovaries using the hollow needle, which is called follicular aspiration. Some women may experience cramping on the day of retrieval, which usually subsides the following day; however, a feeling of fullness or pressure may last for several weeks following the procedure. Step 3: Sperm, usually obtained by ejaculation is prepared for combining with the eggs. Step 4: In a process called insemination, the sperm and eggs are placed in incubators located in the laboratory which enables fertilization to occur. In some cases where fertilization is suspected to be low, intracytoplasmic sperm injection (ICSI) may be used. Through this procedure, a single sperm is injected directly into the egg in an attempt to achieve fertilization. The eggs are monitored to confirm that fertilization and cell division are taking place. Once this occurs, the fertilized eggs are considered embryos. Step 5: The embryos are usually transferred into the woman's uterus anywhere from one to 6 days later, but most commonly it occurs between 2 to 3 days following egg retrieval. At this point, the fertilized egg has divided to become a two-to-four cell embryo. The transfer process involves a speculum which is inserted into the vagina to expose the cervix. A predetermined number of embryos are suspended in fluid and gently placed through a catheter into the womb. This process is often guided by ultrasound. The procedure is usually painless, but some women experience mild cramping. These steps are followed by rest and watching for early pregnancy symptoms. A blood test and potentially an ultrasound will be used to determine if implantation and pregnancy has occurred.

    Fertilized eggs aren’t flushed out on a regular basis. A woman doesn't have a period when the egg is fertilized. Most of the time an egg isn't fertilized because the ovary doesn't release an egg until ovulation which lasts only one day per month. A period happens when an egg is not fertilized within that twenty-four hours the egg is alive.
