How IVF works.

During IVF, medications are often used to help stimulate the development and release of a woman's eggs. The eggs and sperm are then collected and placed together in a laboratory dish to fertilize. If the eggs are successfully fertilized, the embryos are then transferred into a woman's uterus or fallopian tubes. Hopefully one of the fertilized eggs will implant and develop just as in unassisted conception.

The IVF cycle step by step.

An IVF cycle is broken down into four stages:
Stage 1: Ovarian stimulation, monitoring, and ovulation triggering.

The goal of the first stage is to create a large number of mature follicles so as to increase the chances of fertilization. Since a woman's body normally releases one mature egg every month, a medication such as Gonal–f® (follitropin alfa for injection) is used to stimulate the ovaries to develop more follicles. Follicles are fluid-filled sacs in which eggs mature. At the beginning of the cycle, each follicle is approximately 1-2 mm in diameter.

During this stage, injection of a medication such as Cetrotide® (cetrolix acetate for injection) may also be prescribed. This medication is used to prevent a premature surge of luteinizing hormone (LH) that could cause early ovulation.

During this stage, your healthcare provider may use ultrasound to monitor the number and size of maturing follicles in your ovaries. Blood tests may also be used to monitor hormone levels which will help determine the best time to administer medication and to retrieve the eggs.
Stage 2: Egg retrieval

In the second stage, a medication such as Ovidrel® PreFilled Syringe (choriogonadotropin alfa injection) is used to stimulate the release of mature eggs. The healthcare provider will identify the mature follicles using ultrasound, and then, with a needle, withdraw as many eggs as possible from both ovaries. At this point, each follicle is approximately 16-20 mm in diameter.
Stage 3: Fertilization

About two hours before the eggs are retrieved, a semen sample is collected. Approximately 50,000 sperm are placed with each egg in the incubator where they will hopefully form an embryo. When only a few sperm are available, Intracytoplasmic Sperm Injection (ICSI) may be attempted. In this procedure, a single sperm is injected into an egg to facilitate fertilization.

The next day, the eggs will be examined under a microscope to determine whether fertilization has occurred. If it has, the embryos will be ready to transfer into the uterus in about 72 hours.
Stage 4: Embryo transfer

The embryos are placed in a tube and transferred back into the uterus. The procedure is usually painless, though some women may experience some cramping. The number of embryos transferred depends on a woman's age, cause of infertility, pregnancy history, and other factors. For more information about IVF procedures, talk with your healthcare provider.

The uterine lining is prepared for implantation, often by supplementing with progesterone medication.

*Note: In Vitro Fertilization is not the ONLY process to enduce pregnancy and you should research as many ways and find the one that suits you most comfortably before making a rash decision!
