Ivf how is egg retrieval done

The latest information about the Novel Coronavirus, including vaccine clinics for children ages 5 years old and older. Approximately 35 hours after the hCG injection, the egg oocyte retrieval will be performed under sedation.

Intravenous medications will be given to prevent discomfort during the procedure. You will be asked not to have anything to eat or drink after midnight the night before the egg retrieval. If you are taking medications for any other reason, talk to your MD or RN about taking medication prior to retrieval. Once you receive the intravenous medication, the vagina will be cleansed with sterile water.

A needle will be placed through your vagina and into the ovary, under ultrasound guidance. Most women will not feel this procedure at all due to the effects of the intravenous medications.

The follicular fluid which contains the eggs from the follicles in your ovaries is collected in test tubes and passed to the embryologists in the In Vitro Fertilization IVF Lab. The egg retrieval takes approximately minutes. After the procedure is completed, you will be transferred to the recovery room to rest for about an hour. Risks from the egg retrieval include pain, infection in the pelvis and ovaries, injury to the bowel, bladder, uterus, ovaries or major blood vessels.

Since the procedure is done under ultrasound guidance and the needle can be seen on the ultrasound, the chance of serious problems is extremely small.

For this egg retrieval procedure, an ultrasound is used to visually guide a small needle through the top of the vagina into one ovary and then the other. Follicles are entered with the needle and the follicular fluid contents are removed using gentle suction that brings the egg along in the fluid; the entire process usually takes less than 30 minutes.

You may feel some minor cramping the day of the procedure which is usually gone the next day. This may last for a few weeks. The fluid from the follicles — that contains the egg — is suctioned by the IVF physician through small tubing and into a test tube. The test tube is then handed to an embryologist who uses a microscope to find the egg in each test tube of follicular fluid. All the details of the eggs are carefully recorded.

Once eggs reach the lab, experts examine them to determine maturity and quality. Mature eggs are transferred into a special culture medium, placed in an incubator and within a few hours of egg retrieval are fertilized with sperm. There are two ways to fertilize an egg: conventional insemination or intra-cytoplasmic injection ICSI. Which process is used will be determined by your IVF team physicians and embryologists and depends on multiple factors related to the couple going through IVF.

Both methods have approximately the same success rate. For the conventional method, sperm is placed in the culture medium in a small petri dish containing an egg; the sperm and eggs are incubated together in the dish in the lab, allowing the sperm to enter the egg on its own. For ICSI, one sperm is injected into the cytoplasm of the egg using a needle and a sophisticated operative microscope.

Embryo transfer is done at your doctor's office or a clinic and usually takes place two to five days after egg retrieval. If successful, an embryo will implant in the lining of your uterus about six to 10 days after egg retrieval. After the embryo transfer, you can resume your usual daily activities.

However, your ovaries may still be enlarged. Consider avoiding vigorous activity, which could cause discomfort. If you develop moderate or severe pain after the embryo transfer, contact your doctor. He or she will evaluate you for complications such as infection, twisting of an ovary ovarian torsion and severe ovarian hyperstimulation syndrome. About 12 days to two weeks after egg retrieval, your doctor will test a sample of your blood to detect whether you're pregnant.

The chances of giving birth to a healthy baby after using IVF depend on various factors, including:. Talk with your doctor about any factors that apply to you and how they may affect your chances of a successful pregnancy.
