IVF stands for in vitro fertilization. It’s one of the more widely known types of assisted reproductive technology (ART). IVF works by using a combination of medicines and a small surgical procedure to help sperm fertilize an egg, and help the fertilized egg implant in your uterus.
IVF has many steps, and it takes a few weeks to complete the whole process. It sometimes works on the first try, but many people need more than 1 round of IVF to get pregnant.
The first step in IVF is taking fertility medications for a couple of weeks to help your ovaries produce several eggs that are mature and ready for fertilization. This is called ovulation induction. You may get regular ultrasounds or blood tests to measure your hormone levels and keep track of your egg production.
Once your ovaries have produced enough mature eggs, your doctor removes the eggs from your body (this is called egg retrieval). Egg retrieval is a minor surgical procedure that’s done at your doctor’s office or at a fertility clinic.
You’ll get medicine to help you be relaxed and comfortable during the procedure so that there is no pain . Using an ultrasound to see inside your body, the doctor puts a thin, hollow tube through your vagina and into the ovary and follicles that hold your eggs. The needle is connected to a suction device that gently pulls the eggs out of each follicle.
In a lab, your eggs are mixed with sperm cells from your partner or a donor — this is called insemination. The eggs and sperm are stored together in a special container, and fertilization happens. For sperm that have lower motility (don’t swim as well), they may be injected directly into the eggs to promote fertilization. (Known as ICSI) . As the cells in the fertilized eggs divide and become embryos, people who work at the lab monitor the progress.
About 3-5 days after the egg retrieval, 1 or more embryos are put into your uterus (this is called embryo transfer). The doctor slides a thin tube through your cervix into your uterus, and inserts the embryo directly into your uterus through the tube.
Pregnancy happens if any of the embryos attach to the lining of your uterus. Embryo transfer is done at your doctor’s office or at a fertility clinic, and it’s usually not painful.
Plan on resting for the rest of the day after your embryo transfer. You can go back to your normal activities the next day. You may also take pills or get weekly shots of a hormone called progesterone for the first few weeks after the embryo transfer. The hormones make it easier for the embryo to survive in your uterus.
Like all medications and medical procedures, IVF has some risks and possible side effects. These include:
Your doctor can talk with you about any questions or concerns you have about IVF risks and side effects.
IVF can also be difficult emotionally, both for the person having the procedures and for their partner and/or family. Many people doing IVF treatments struggle with depression and anxiety throughout the process.
Talking with people who’ve been through fertility struggles and IVF can be really helpful if you’re feeling overwhelmed or discouraged. Online and in-person communities are also good places to meet people who understand what you’re going through and can offer advice and support. Counselors and therapists can also be sources of comfort.
