In vitro fertilization (IVF) is a complex series of procedures used to help with fertility or prevent genetic problems and assist with the conception of a child.
During IVF, mature eggs are collected (retrieved) from ovaries and fertilized by sperm in a lab. Then the fertilized egg (embryo) or eggs (embryos) are transferred to a uterus. One full cycle of IVF takes about three weeks. Sometimes these steps are split into different parts and the process can take longer.
IVF is the most effective form of assisted reproductive technology. The procedure can be done using your own eggs and your partner’s sperm. Or IVF may involve eggs, sperm or embryos from a known or anonymous donor. In some cases, a gestational carrier — a woman who has an embryo implanted in her uterus — might be used.
Your chances of having a healthy baby using IVF depend on many factors, such as your age and the cause of infertility. In addition, IVF can be time-consuming, expensive and invasive. If more than one embryo is transferred to your uterus, IVF can result in a pregnancy with more than one fetus (multiple pregnancy).
Your doctor can help you understand how IVF works, the potential risks and whether this method of treating infertility is right for you.
How it is done
Couples who decide on IVF enter a process that will take about 20 days.
In the first stage, the number of quality eggs is increased by inducing the mother’s ovaries with the necessary drugs.
The eggs are then collected with a fine needle through painless and short-term intervention. at the same time, the sperm cells are taken from the father candidate and passed through the necessary preparation steps and they are combined with each egg as a sperm.
Following the fertilization, the best quality of the embryos obtained is selected by transferring the embryos to the uterus through a painless and short-term procedure, usually on the 3rd day and, if necessary and appropriate, on the 2nd and 5th days.After that, the waiting period of the family starts and she gets the pregnancy test on the required day.
Firstly, the sperm sample is taken from the father candidate on the same day, is being washed.
The eggs are put together with the appropriate number of sperm in specially prepared solutions and after 18 hours, the fertilized eggs are being separated. In the following days the nascent embryo cell number, called the cell is no longer the case of fragmentation if relations with each other and if the cells are evaluated and classified. a few of them from embryos that are classified according to the appropriate quality are transferred to the mother. Other embryos are frozen and stored.
IVF method couple who decide to enter a process in about 20 days. The first stage of drug treatment is applied to obtain a sufficient number of eggs. Mothers of ovaries induced by drug treatment are necessary to increase the number of quality eggs after treatment lasts about 10-14 days, painless and short-term intervention with eggs are collected using a thin needle under anesthesia. The collected eggs are separated from other cells in the laboratory around extracting quality ones are processed. and at the same time that sperm cells are passed from father to taking the necessary preparation of each candidate are combined to become a sperm to the egg (fertilization).
Eggs and sperm are combined together in a special solution and the formation of the fertilization process is applied as the expected about 16-18 hours. Only this treatment must be a sufficient number of eggs and sperm for implementation. If the number or quality of sperm or eggs is less convenient if these methods fail. In this case, another treatment microinjection (ICSI) should be used.
The tube is baby and the only difference fertilization shape between microinjection injected with IVF sperm and egg together to put fertilization, a single sperm into each egg microinjection methods are expected to be self-microscopic catheters.
Usually, 3 days selecting the best quality from the resulting embryo following fertilization, necessary and, if appropriate, of the 2nd and 5th day from other days, the embryos are still painful and short-term transferred to the uterus with a transaction (transfer) is performed. After that, the family enters day waiting period is required and make the pregnancy testA
