Do you want to have children and are you unable to conceive naturally? This may be possible after all through ‘in vitro fertilization‘ ( IVF ). Fertilization takes place outside your body, in a laboratory. It is a fertility treatment for women who cannot conceive naturally. During this treatment, several eggs are ripen using hormones. The mature eggs are then removed from your body via a puncture. The partner’s sperm is brought to the eggs in the laboratory. After successful fertilization, an embryo is placed back in your uterus. Hopefully a pregnancy will then arise. This does not always work: the chance of a pregnancy occurring is about 25 percent per treatment.
In Vitro Fertilization Procedure
The IVF treatment consists of 5 phases which includes the simulation of the ovaries, collecting the eggs, In Vitro fertilization, embryo transfer and freezing of embryos(optional). Lets have a look one by one.
Phase 1 : Simulation of ovaries (SuperOvulation)
The first steps is to develop a lot of eggs in the ovaries which is often referred to as Superovulation. The procedure involves the injection of hormones which simulates the ovaries. A contraceptive pill is prescribed before starting the treatment which ensures that cycle is in control and helps in the planning of the treatment.
So you start with taking the contraceptive pills. On the first day of your period, you must call the doctor and then the doctor will advise you to take the injections(one injection a day).
Phase 2 : Collection of the Eggs
Collection process starts when the eggs are large enough of size 15 to 20 mm. The final injection of hCG is given just before the ovulation. The collection of eggs starts about 36 hrs after hCG injection. The hollow needle is inserted in the ovaries through vagina to collect the eggs. This takes about 15 to 30 minutes and is usually done under local anesthesia.
Phase 3 : In Vitro Fertilization
The next phase is the In Vitro Fertilization(IVF). The eggs collected from the previous phase are injected with the sperm in a fertility laboratory. This can be done using one of the two techniques – IVF or ICSI. 18 to 24 hours later, the eggs are examined under the microscope to determine how many eggs have been fertilized. The fertilized eggs (zygotes) are divided further in the incubator and grow into multicellular embryos.
Phase 4 : Embryo Transfer
Depending on the number of embryos, their quality and whether a particular treatment is required on the embryos, embryos are monitored in the laboratory for one to five days before they are transferred back to the uterus.
Legislation specifies how many embryos may be transferred. This depends on the age of the patient and the number of previous attempts. The aim is to maximize the chances of pregnancy and at the same time limit the risk of multiple pregnancies. Just before the transfer, the embryologist will discuss the quality of the embryos with you.
The placement itself is done with a fine catheter that is inserted through the cervix into the uterine cavity. The embryos are left in a small drop of liquid. The procedure is painless (like a normal gynecological exam) and is done without anesthesia. Afterwards, the patient can return home immediately.
Phase 5 : Freezing of Embryo(Optional)
If top quality embryos remain after the embryo transfer, they can be frozen . During a new IVF attempt, the frozen eggs must first be thawed in a cryocycle. The transfer of thawed embryos takes place in a spontaneous, an optimally stimulated or a substituted cycle.
So are you pregnant with an IVF process, You can track the pregnancy here.
