In Vitro Fertilization (IVF) Q & A

What is in vitro fertilization?

In vitro fertilization (IVF) is one type of assisted reproductive technology. To perform IVF, Dr. Macer stimulates the ovaries with hormones identical to the ones made in the brain. This allows him to obtain many eggs, as opposed to a single egg that is normally grown with each menstrual cycle. Once mature, he removes the eggs and fertilizes them with sperm in his state of the art embryology lab, creating embryos. The entire process usually takes about 10-12 days. 

Once ready to conceive, the embryos are then placed into the woman’s uterus or kept frozen and preserved for future IVF procedures.

Who is a good candidate for in vitro fertilization?

Dr. Macer uses IVF to treat infertility caused by numerous conditions, including:

  • Unexplained infertility
  • Individuals desiring genetic testing or gender selection
  • Blocked or damaged fallopian tubes
  • Ovulation disorders
  • Same sex relationships
  • Ovum donation or surrogacy
  • Premature ovarian failure
  • Low sperm count
  • Sperm motility problems

When sperm problems factor into a couple’s infertility, Dr. Macer may recommend IVF with intracytoplasmic sperm injection (ICSI). During ICSI, sperm are examined, the healthiest ones separated, and then a single sperm is injected directly into the egg.

What happens during in vitro fertilization?

In vitro fertilization follows four steps:

Ovarian stimulation

You’ll receive injections of two medications: one to stimulate egg maturation inside the ovaries and the second to prevent ovulation. You’ll take the medications for about 8-10 days. During that time, Dr. Macer regularly monitors your ovaries using ultrasound and blood tests so he can determine when the eggs are mature and ready to be fertilized.

Egg retrieval

When your eggs are mature, they’re retrieved using a minimally invasive procedure. Dr. Macer uses ultrasound to guide a needle through the vaginal wall and into the ovary, then gently withdraws the mature eggs. The procedure is under conscious sedation and you can go home within an hour of the retrieval. 


Whether you’re using your partner’s sperm or donated sperm, it’s collected while your eggs are retrieved. The eggs and sperm are placed together in a small dish to allow fertilization to occur naturally, or ICSI is performed. The day after, Dr. Macer checks the eggs to confirm they were fertilized.

Embryo transfer

For patients desiring to get pregnant immediately, Dr. Macer performs what is called a “Fresh” transfer. About five days after fertilization, he uses a long, thin tube to transfer the best quality embryo(s) into the uterus. The transfer is quick, as the tube is simply inserted through your cervix and the embryo(s) is precisely placed in your uterus. If you have extra embryos that aren’t placed in your uterus, they can be frozen and saved. Around 11 days after the embryo transfer, you’ll be tested to see if you’re pregnant. 

Current evidence suggests that for some patients, there is a higher pregnancy rate when transferring “frozen” embryos. Instead of immediately transferring embryos, they are frozen and transferred at a later time. Not only does this allow the uterine environment to recover from the stimulation, but it also allows the lab to perform genetic testing on the embryos, if desired. The embryos can be frozen for at least 20 years without a decline in their potential to result in a live birth.
