What to Expect Along the Path to Conceiving With IVF
Starting the IVF pregnancy treatment process can be an exciting and nerve-wracking experience. Usually, IVF is pursued only after other fertility treatments have failed. You may have been trying to conceive for months or, more likely, for years and years.
But this is not always the case. Sometimes, IVF is the very first treatment tried.
For example, IVF may be the first option if:
- A gestational carrier is needed
- An egg donor is being used
- If a woman’s fallopian tubes are blocked
- Severe cases of male infertility
- When previously cryopreserved eggs are being used
Still, even in these cases, IVF may come after years of trying to get pregnant and several fertility tests.1
Just looking over the schedule of ultrasounds, blood work, and injections can have you feeling fragile. (And that’s before the drugs can mess with your moods!) Add to that the cost of IVF, especially if you’re paying out-of-pocket, and it’s no surprise if you’re feeling worried.
However, the more you understand about what’s coming next, the more in control you’ll feel. While every clinic’s protocol will be slightly different and treatments are adjusted for a couple’s individual needs, here is a step-by-step breakdown of what generally takes place during in vitro fertilization, as well as information on the risks, costs, and what’s next if your IVF treatment cycle fails.
In Vitro Fertilization Basics
IVF stands for in vitro fertilization. In vitro means “in the lab” and fertilization refers to conception. Usually, IVF involves taking many eggs (retrieved via a transvaginal ultrasound-guided needle) and placing them in a petri dish with specially washed sperm cells (retrieved via masturbation.)
If all goes well, some of the retrieved eggs will become fertilized by the sperm cells and become embryos. One or two of those healthy embryos will be transferred to your uterus.
In some cases, the sperm cells need extra help with the fertilization process. ICSI, or intracytoplasmic sperm injection, may be used, which is an assisted reproductive technology that involves injecting a single sperm cell into an egg.
This may be done in cases of severe male infertility, previously cryopreserved eggs, preimplantation genetic testing of embryos (PGT), or if past IVF cycles have failed at the fertilization stage.2
But before eggs can be retrieved, the ovaries must be stimulated. Without the help of fertility drugs, your body will typically only mature one (or maybe two) eggs each month. For conventional IVF, you need lots of eggs. Injectable fertility drugs are used to stimulate the ovaries to mature a dozen or more eggs for retrieval.3
This isn’t always the case, however. With minimal stimulation IVF (aka mini IVF), oral fertility drugs or very low dose injectable drugs may be used to stimulate just a few eggs.
IVF Success Rates
IVF is pretty successful. According to a study of approximately 156,000 women, the average live-birth rate for the first cycle was 29.5%.4 This is comparable to the success rates for a natural cycle in couples with healthy fertility
Your best odds for success may come from repeated treatment cycles. This same study found that after six IVF cycles, the cumulative live-birth rate was 65.3%. These six cycles usually took place over 2 years.
Age does play an important role in your success, as does the reason for your infertility. Using an egg donor will also affect your success.
Be sure to discuss your personal odds for success with your doctor before starting treatment. While your doctor can’t tell you for certain whether treatment will work for you, she should have an idea of your odds in relation to the average and in relation to other patients like yourself.
IVF Costs and Risks
IVF is expensive. It’s also frequently not covered by insurance, putting the treatment out of reach for many people who need it.5 In fact, studies have found that only one in four couples who need IVF to conceive can actually get the treatment they need.
The average cost of IVF often quoted is between $12,000 and 15,000 per cycle. Some say this estimate is really below the reality, and the out-of-pocket average costs are higher.
One study found that the average couple paid $19,234 for their initial IVF cycle, with an additional $6,955 for each additional cycle. (Why such a difference between the first and subsequent? Partially because some of those second and third cycles are frozen embryo transfers.)6
This is all for conventional, no-frills IVF. If you need any additional technologies—like ICSI, PGT, assisted hatching, an egg donor, or a gestational carrier—costs will be higher. Sometimes much higher.
There are ways to pay less or get financial assistance for IVF treatment, and you should look into all your options before making a decision on whether or not you can afford treatment.
Safety and Risks of IVF
IVF is generally safe, but as with any medical procedure, there are risks. Your doctor should explain all the possible side effects and risks of each procedure before you begin.
Ovarian hyperstimulation syndrome (OHSS) occurs in 10% of women going through IVF treatment. For most women, symptoms will be mild, and they will recover easily.7 For a small percentage, OHSS can be more serious and may require hospitalization. Less than 1% of women going through egg retrieval will experience blood clots or kidney failure due to OHSS.
The egg retrieval may cause cramping and discomfort during or after the procedure. Rare complications include accidental puncture of the bladder, bowel, or blood vessels; pelvic infection; or bleeding from the ovary or pelvic vessels.8
If pelvic infection does occur, you’ll be treated with intravenous antibiotics. In rare cases of severe infection, the uterus, ovaries or fallopian tubes may need to be surgically removed.
The embryo transfer may cause mild cramping during the procedure. Rarely, women will also experience cramping, bleeding, or spotting after the transfer. In very rare cases, infection can occur. Infection is typically treated with antibiotics.
There is a risk of multiples, which includes twins, triplets, or more. Multiple pregnancies can be risky for both the babies and the mother. It’s important to discuss with your doctor how many embryos to transfer, as transferring more than necessary will increase your risk of conceiving twins or more. When embryos have been tested with PGT, typically only a single embryo is transferred.
Some research has found that IVF may raise the risk of some very rare birth defects, but the risk is still relatively low.9 Research has also found that the use of ICSI with IVF, in certain cases of male infertility, may increase the risk of infertility and some sexual birth defects for male children. This risk, however, is very low (less than 1%).10
The Cycle Before Treatment
The cycle before your IVF treatment is scheduled, you may be put on birth control pills. This may seem backward—aren’t you trying to get pregnant?
Using birth control pills before a treatment cycle has been shown to potentially improve your odds of success. Also, it may decrease your risk of ovarian hyperstimulation syndrome and ovarian cysts.11
But not every doctor uses birth control pills the cycle before. Another possibility is that your doctor will ask you to track ovulation the cycle before. Most likely, she will recommend using an ovulation predictor kit. However, she may also suggest basal body temperature charting, especially if you have experience charting your cycles.
Then, you will need to let your doctor know as soon as you detect ovulation. Sometime after ovulation, the fertility clinic may then have you start taking a GnRH antagonist (like Ganirelix) or a GnRH agonist (like Lupron). These are injectable drugs, but some are available as a nasal spray or implant.
These medications allow your doctor to have complete control over ovulation once your treatment cycle begins. If you don’t get your cycles on your own, your doctor may take yet another approach. In this case, he may prescribe progesterone in the form of Provera. This would bring on your period.
In this case, your doctor will probably ask that you start taking the GnRH agonist or antagonist about 6 days or more after your first Provera pill. Again, though, this may vary. Always follow your doctor’s instructions.
When You Get Your Period
The first official day of your treatment cycle is the day you get your period. (Even though it may feel like you’ve already begun with the medications you started before in step one.)
On the second day of your period, your doctor will likely order blood work and an ultrasound. This will be a transvaginal ultrasound. An ultrasound during your period isn’t exactly pleasant, but try to remember this is the same for every woman going through IVF.
These first-day ultrasounds and blood work are referred to as your baseline blood work and your baseline ultrasound. In your blood work, your doctor will be looking at your estrogen levels, specifically your E2 or estradiol. This is to make sure your ovaries are “sleeping.” That’s the intended effect of the Lupron shots or GnRH antagonist.
The ultrasound is to check the size of your ovaries. Your doctor will also look for ovarian cysts. If there are cysts, your doctor will decide how to deal with them. Sometimes your doctor will just delay treatment for a week. Most cysts resolve on their own with time. In other cases, your doctor may aspirate the cyst (suck out the fluid) with a needle.
Usually, these tests will be fine. If everything looks OK, treatment moves on.
Ovarian Stimulation and Monitoring
Ovarian stimulation with fertility drugs is the next step. Depending on your treatment protocol, this may mean anywhere from one to four shots every day for about a week to 10 days.12
You are probably a pro at self-injection by now, since Lupron and other GnRH agonists are also injectables. Your clinic should teach you how to give yourself the injections before treatment begins. Some clinics offer classes with tips and instruction.

- Commonly prescribed fertility drugs
- GnRH agonist (Lupron) side effects
- GnRH antagonists (Antagon, Ganirelix, Orgalutran, and Cetrotide) side effects
- Gonadotropin side effects
During ovarian stimulation, your doctor will monitor the growth and development of the follicles.
At first, this may include blood work and ultrasounds every few days. Your doctor will be monitoring your estradiol levels. During the ultrasounds, your doctor will monitor the oocyte growth. (Oocytes are the eggs in your ovaries.)
Monitoring the cycle is very important. This is how your doctor will decide how to adjust your medications.
You may need to increase or decrease dosages. Once your largest follicle is 16 to 18 mm in size, your clinic will probably want to see you daily.
Final Oocyte Maturation
The next step in your IVF treatment is triggering the oocytes to go through the last stage of maturation. The eggs must complete their growth and development before they can be retrieved.
This last growth is triggered with human chorionic gonadotropin (hCG). Brand names for this include Ovidrel, Novarel, and Pregnyl. Timing this shot is vital. If it’s given too early, the eggs will not have matured enough. If given too late, the eggs may be “too old” and won’t fertilize properly.13
The daily ultrasounds at the end of the last step are meant to time this trigger shot just right. Usually, the hCG injection is given when four or more follicles have grown to be 18 to 20 mm in size and your estradiol levels are greater than 2,000 pg/ML.14
This shot is typically a one-time injection. Your doctor will likely give you an exact hour to do this shot. Be sure to follow these instructions!
IVM vs. IVF
During conventional IVF, eggs must complete their development and growth before being retrieved. IVM treatment is slightly different. IVM stands for in vitro maturation. It’s a relatively new technology that is similar to IVF but significantly differs at this point in the process.
During IVM, the eggs are retrieved before they go through all stages of maturity. You will not have a “trigger shot” during IVM. The eggs retrieved will be matured in the lab environment. Once the eggs are matured, the rest of the steps follow the IVF process.15
What If the Follicles Don’t Grow
We’ve assumed to this point that the ovarian stimulation drugs have worked properly. But that isn’t always how it goes. Sometimes the follicles don’t grow. Your doctor may increase the medications, but if your ovaries still don’t respond, the cycle will likely be canceled.
This doesn’t mean another cycle won’t work. You may just need different medications. However, if this occurs repeatedly, your doctor may suggest using an egg or embryo donor. You may want to get a second opinion before moving forward at this point.
What If You’re at Risk for OHSS
Another possible problem is your ovaries respond too well. If your doctor thinks you’re at risk of developing severe ovarian hyperstimulation syndrome (OHSS), your trigger shot will be canceled and the cycle will be stopped at this point.
Another possibility is your doctor will retrieve the eggs, fertilize them, but delay the embryo transfer. This is because pregnancy can worsen and extend recovery from OHSS.16 Once your body recovers, you can try a frozen embryo transfer.
During your next cycle, your doctor may suggest lower doses of medications, try different medications before your cycle starts, or even suggest IVM instead of IVF (explained above.)
What If You Ovulate Prematurely
While not common, a cycle may also be canceled if ovulation occurs before retrieval can take place. Once the eggs ovulate on their own, they can’t be retrieved. Your doctor will likely tell you to refrain from sexual intercourse.
It’s important you follow these instructions! It’s possible you’ve ovulated up to a dozen eggs. Maybe even more. There is danger to both the mother and children if you got pregnant naturally with even half of those eggs.17
How Often Are IVF Cycles Canceled?
Cancellation happens in 10% to 20% of IVF treatment cycles.18 The chance of cancellation rises with age, with those older than age 35 more likely to experience treatment cancellation.
About 34 to 36 hours after you receive the hCG shot, the egg retrieval will take place.19 It’s normal to be nervous about the procedure, but most women go through it without much trouble or pain.
Before the retrieval, an anesthesiologist will give you some medication intravenously to help you feel relaxed and pain-free. Usually, a light sedative is used, which will make you “sleep” through the procedure. This isn’t the same as general anesthesia, which is used during surgery. Side effects and complications are less common.20
Once the medications take their effect, your doctor will use a transvaginal ultrasound to guide a needle through the back wall of your vagina, up to your ovaries. She will then use the needle to aspirate the follicle, or gently suck the fluid and oocyte from the follicle into the needle. There is one oocyte per follicle. These oocytes will be transferred to the embryology lab for fertilization.
The number of oocytes retrieved varies but can usually be estimated before retrieval via ultrasound. The average number of oocytes is 8 to 15, with more than 95% of patients having at least one oocyte retrieved.21
After the retrieval procedure, you’ll be kept for a few hours to make sure all is well. Light spotting is common, as well as lower abdominal cramping, but most feel better in a day or so after the procedure. You’ll also be told to watch for signs of ovarian hyperstimulation syndrome, a side effect from fertility drug use during IVF treatment in 10% of patients.19
While you’re at home recovering from the retrieval, the follicles that were aspirated will be searched for oocytes, or eggs. Not every follicle will contain an oocyte.
Once the oocytes are found, they’ll be evaluated by the embryologist. If the eggs are overly mature, fertilization may not be successful. If they are not mature enough, the embryology lab may be able to stimulate them to maturity in the lab.
Fertilization of the oocytes must happen with 12 to 24 hours.22 Your partner will likely provide a semen sample the same morning you have the retrieval. The stress of the day can make it difficult for some, and so just in case, your partner may provide a semen sample for backup earlier in the cycle, which can be frozen until the day of the retrieval.
Once the semen sample is ready, it’ll be put through a special washing process, which separates the sperm from the other stuff that is found in semen. The embryologist will choose the “best-looking sperm,” placing about 10,000 sperm in each culture dish with an oocyte. The culture dishes are kept in a special incubator, and after 12 to 24 hours, they are inspected for signs of fertilization.
With the exception of severe male infertility, 70% of the oocytes will become fertilized.23
In the case of severe male infertility, ICSI (pronounced ick-see) may be used to fertilize the eggs, instead of simply placing them in a culture dish. With ICSI, the embryologist will choose a healthy-looking sperm and inseminate the oocyte with the sperm using a special thin needle.
About three to five days after the retrieval, an embryologist will identify the healthiest looking embryos. This is typically done visually (with a microscope), but in some cases, genetic screening is performed. This is known as preimplantation genetic diagnosis (PGD) or preimplantation genetic screening (PGS.)24
Sometimes, with PGD/PGS, the embryos are cryopreserved and transfer is delayed until the next cycle. Otherwise, a “fresh” transfer takes place. The procedure for embryo transfer is just like IUI treatment. You won’t need anesthesia.
During the embryo transfer, a thin tube, or catheter, will be passed through your cervix. You may experience very light cramping but nothing more than that. Through the catheter, they will transfer the embryos, along with a small amount of fluid.25
The number of embryos transferred will depend on the quality of the embryos and discussion with your doctor. Depending on your age, anywhere from one to five embryos may be transferred. Transferring two embryos is the most common option.
More doctors are suggesting having just one embryo transferred and then freezing the rest. This is known as elective single embryo transfer (eSET), and it can reduce your risk of a multiple pregnancy. When you get pregnant with just one healthy baby, you reduce your risks for pregnancy complications.26 Speak to your doctor to find out if elective single embryo transfer is best for you.
After the transfer, you’ll stay lying down for a couple hours (bring a book) and then head home. If there are “extra” high-quality embryos left over, you may be able to freeze them. This is called embryo cryopreservation. They can be used later if this cycle isn’t successful in a frozen embryo transfer, or they can be donated.
Progesterone Support and the 2-Week Wait
On or after the day of your retrieval, and before the embryo transfer, you’ll start giving yourself progesterone supplements. Usually, the progesterone during IVF treatment is given as an intramuscular self-injection as progesterone in oil. (More shots!) Sometimes, though, progesterone supplementation can be taken as a pill, vaginal gel, or vaginal suppository.
Besides the progesterone, there really isn’t much going on for the next 2 weeks. In some ways, the two weeks after the transfer may be more difficult emotionally than the 2 weeks of treatment. During the previous steps, you will have visited your doctor perhaps every other day. Now, after transfer, there will be a sudden lull in activity.
You may have lots of questions about the two-week wait. Can you have sex? What if you have cramps? Of course, your doctor is the number one source for any of your concerns.
All you can do is wait the 2 weeks and see if pregnancy takes place. It can help to keep busy with your life during this wait time and avoid sitting and thinking about whether or not treatment will be successful.
Pregnancy Test and Follow-Up
About 9 to 12 days after the embryo transfer, a pregnancy test is ordered.27 This is usually a serum pregnancy test (more blood work) and also will include progesterone levels testing. The test may be repeated every few days.
If the test is positive, you may need to keep taking the progesterone supplementation for another several weeks. Your doctor will also follow up with occasional blood work and ultrasounds to monitor the pregnancy and watch for miscarriages or ectopic pregnancies.
Possible IVF Pregnancy Risks
Your doctor will also monitor whether or not the treatment led to a multiple pregnancy. IVF has a higher risk of conceiving multiples, and a multiple pregnancy carries risks for both the mother and the babies.28 Risks of a multiple pregnancy include premature labor and delivery, maternal hemorrhage, C-section delivery, pregnancy induced high blood pressure, and gestational diabetes.29
If it’s a high-order pregnancy (4 or more), your doctor may discuss the option of reducing the number of fetuses in a procedure called a “multifetal pregnancy reduction.” This is sometimes done to increase the chances of having a healthy and successful pregnancy.
Women who conceive with IVF are more likely to experience spotting in early pregnancy, though it’s more likely for their spotting to resolve without harm to the pregnancy.30
The risk of miscarriage is about the same for women who conceive naturally, with the risk going up with age. For young women in their 20s, the rate of miscarriage is as low as 15%, while for women over 40, the rate of miscarriage may be over 50%.31
There is a 2% to 4% risk of ectopic pregnancy with IVF conception.32 If you developed OHSS from the fertility drugs, and you get pregnant, recovery may take longer.
When IVF Treatment Fails
If the pregnancy test is still negative 12 to 14 days post-transfer, your doctor will ask you to stop taking the progesterone. Then, you’ll wait for your period to start.
The next step will be decided by you, your partner, and your doctor. If this was your first cycle, another cycle may be recommended. Remember that your best chances for success are after doing several cycles.
Having a treatment cycle fail is never easy. It’s heartbreaking. It’s important, however, to keep in mind that having one cycle fail doesn’t mean you won’t be successful if you try again. There are many steps you can take after a treatment cycle fail.
