A Step-By-Step Look at the IVF Process

When you think of common fertility treatments, in vitro fertilization (IVF) probably appears near the top of your list. There’s a reason for that.

IVF has been around for decades and you most likely already know the basic idea behind IVF: uniting egg and sperm outside the body in a culture. But there’s so much more to IVF that happens before and after that. Here’s a closer look at the IVF process in five steps.


IVF is commonly used to treat:

  • Older women with fertility issues
  • Women with damaged or blocked fallopian tubes
  • Women with endometriosis
  • Male infertility caused by low sperm count or blockage

The IVF Process in Five Steps

Boost your egg production through superovulation

You’ll be given fertility drugs that will begin a process called stimulation—or superovulation, says the National Institutes of Health (NIH). In other words, the drugs—which contain Follicle Stimulating Hormone—will tell your body to produce more than just the normal one egg per month.

The more eggs you produce, the more chances you’ll have of a successful fertilization later on in the treatment.

You’ll receive transvaginal ultrasounds and blood tests on a regular basis during this step in the IVF process to check on your ovaries and monitor your hormone levels.

Remove the eggs

A little more than a day before your eggs are scheduled to be retrieved from your body, you’ll receive a hormone injection that will help your eggs mature quickly.

Then, you’ll have a minor surgical procedure—called follicular aspiration—to remove the eggs. This is generally done as an outpatient surgery in your doctor’s office, according to the NIH.

During the procedure, your doctor will use an ultrasound to guide a thin needle into each of your ovaries through your vagina. The needle has a device attached to it that suctions the eggs out one at a time.

If this part sounds painful, don’t worry—you’ll probably be given medication beforehand so that you won’t feel any discomfort. You may experience some cramping afterward, but this usually disappears within a day, the NIH explains.

Collect your partner’s sperm

While your eggs are being removed, your partner is going to need to provide a sperm sample. The sperm are then put through a high-speed wash and spin cycle in order to find the healthiest ones.

Unite sperm and eggs

Now comes the part of IVF that everyone’s the most familiar with—combining your partner’s best sperm with your best eggs. This stage is called insemination.

It usually takes a few hours for a sperm to fertilize an egg. Your doctor may also inject the sperm directly into the egg instead, a process known as intracytoplasmic sperm injection (ICSI).

Transfer the embryo(s) into your uterus

Once your eggs have been collected you’ll receive yet another medication. This one is meant to prep the lining of your uterus to receive the embryos that will be transferred back into you.

About three to five days after fertilization, your doctor will place the embryos in your uterus using a catheter. Like step number three, this part of IVF is performed in your doctor’s office while you are awake.

Multiple embryos are transferred back into you in the hopes that at least one will implant itself in the lining of your uterus and begin to develop. Sometimes more than one embryo ends up implanting, which is why multiples are common in women who use IVF.

The IVF process basically replicates natural reproduction. The next step after the IVF process determines whether the procedure worked—the pregnancy test.
