In Vitro Fertilization (IVF)
IVF at a glance
- In vitro fertilization (IVF) means “fertilization in glass,” which involves fertilization of a woman’s egg by a man’s sperm outside of the body and in a lab.
- TRM offers patients three IVF strategies: standard IVF, minimal stimulation IVF (mini-IVF) and natural cycle IVF (sometimes referred to as fresh-cycle IVF).
- IVF offers the highest chance of pregnancy in the shortest period of time for virtually every diagnosis, though it is not appropriate for all couples.
What is IVF?
In vitro fertilization (IVF) means “fertilization in glass,” which involves fertilization of a woman’s egg by a man’s sperm outside of the body and in a lab. In general, IVF offers couples and women experiencing infertility the highest chance for conception. For many couples, a single attempt of IVF is more likely to be successful than many months of other treatments.
If we had a Hall of Fame, Kim, Jimmy and son Cooper would be in it.
The reason for IVF’s high success rates is that it allows for the interaction of more eggs and sperm than any other procedure. Drugs increase the number of eggs a woman can produce in a month. We evaluate fertilized eggs that develop into embryos to determine which ones are most likely to result in pregnancy, before we place the embryo(s) into the uterus.
IVF is not appropriate for all couples. However, for virtually every diagnosis, IVF offers the highest chance of pregnancy in the shortest period of time.
At TRM, we try to demystify the IVF process and make it easy to understand. We promise to give you realistic expectations of what IVF can and cannot do, so that you can make the best, most informed decision.
Cost of IVF & PGT
Because each patient is different, so is treatment and, ultimately, the cost of fertility treatment. While we are happy to provide some average costs for some of our treatments, please note that the costs listed below will vary. Specific costs will be based on an individual’s treatment plan and the amount of medications required in the customized treatment cycle.
- Natural cycle/minimal stimulation IVF – $8,500
- This is the average cost for treatment, anesthesia and medications.
- This does not include diagnostic testing, some of which may be a covered benefit with insurance. In addition, cryopreservation/storage fees are separate and dependent upon the patient’s request for such services.
- Standard IVF – $17,000
- This is the average cost for treatment, anesthesia and medications.
- This does not include diagnostic testing, some of which may be a covered benefit with insurance. In addition, cryopreservation/storage fees are separate and dependent upon a patient’s request for such services.
- PGT, or embryo preimplantation genetic testing services – Additional $5,300 per cycle.
- We offer these services because genetic flaws in embryos can result in failed implantation, miscarriage and birth defects. The two PGT options are pre-implantation genetic diagnosis, which tests embryos for genetic or chromosomal disorders, and pre-implantation genetic screening, which evaluates embryos for multiple abnormalities at once.
- The cost of PGT services could be increased if more than an average number of embryos are available to be tested.
Why IVF increases chances of pregnancy
IVF maximizes pregnancy rates by using normal human biology to our advantage. In general, women are born with around two million eggs. Most of these eggs are in hibernation within the ovary. Every month a batch of these eggs comes out of hibernation.
Typically, one egg from this batch ovulates while others die. Unfortunately, there is no guarantee that the best quality egg is the one that will ovulate.
The reason most of the eggs die is because there is not enough follicle stimulating hormone (FSH) to support the growth of all of the eggs. One egg essentially steals the hormone and the other eggs degenerate.
By stimulating women with injections of FSH, the IVF process saves most of these eggs from being lost. The pregnancy rates are generally far higher than what occurs in a normal menstrual cycle, because multiple eggs are harvested. And we can select the very best embryos for placement in the uterus.
The chance of IVF success depends on many factors including:
- Age of the female partner
- Prior pregnancy history
- Cause of infertility
- Ovarian reserve.
From the time a woman decides she wants to do IVF, the entire process takes five to seven weeks to completion. To date, IVF offers most infertile couples their best chance of conception. IVF has been used to successfully treat a wide array of fertility problems including blocked fallopian tubes, low sperm count, polycystic ovary syndrome, endometriosis and unexplained infertility.
What are the risks of IVF?
Most couples proceed through IVF and pregnancy without difficulty, but there are some risks associated with IVF to the mother and risks to the baby. However, unless the mother has twins or other underlying conditions, her pregnancy will not be considered “high risk.”
Risks to the mother
Multiple gestation, which is having twins or more, is the most common of all IVF-related risks. Twins occur in 20-30 percent of successful IVF cycles, and higher numbers of babies can also occur.
Multiple gestation places the babies at risk for preterm delivery, which involves health risks for the child (see below Risks to the baby). Mothers are more likely to have complications of pregnancy including preeclampsia, diabetes, blood clots, preterm labor, cesarean section and postpartum hemorrhage.
We adhere closely to the American Society for Reproductive Medicine (ASRM) guidelines on number of embryos to transfer, thus maximizing chances of successful pregnancy while safely limiting the possibilities of twins and higher-order gestations of three or more babies. If a woman has excess embryos, these may be frozen for future use.
Ovarian hyperstimulation syndrome (OHSS)
OHSS is a condition in which the ovaries get very large and filled with fluid in response to the gonadotropin medications. Factors are released by the ovaries that cause a woman’s blood vessels to leak fluid into the pelvis.
In mild forms of OHSS, a woman may have symptoms of bloating and pelvic discomfort. This occurs in 10-20 percent of gonadotropin cycles and resolves quickly after treatment ends.
In severe cases a woman may have difficulty urinating, become dehydrated, gain weight rapidly, and have organ complications involving the lungs, kidneys and liver. This is rare, occurring in 1percent of cycles. These women may require hospitalization.
Women are at increased risk of blood clots when they have OHSS, and any symptoms of leg pain or difficulty breathing should be reported to a physician immediately.
Risk factors for OHSS include:
- Young age
- Low body weight
- Higher doses of gonadotropins
- High absolute or rapidly rising estrogen levels
- Previous episodes of OHSS
- High number of developing follicles.
Among women who conceive, symptoms of OHSS may worsen at the time pregnancy is detected and may take longer to completely resolve.
Ectopic pregnancies (sometimes called tubal pregnancies) occur when a fertilized egg implants itself outside the uterus. The embryo may implant in the fallopian tube, or less commonly, in the cervix, ovary or pelvic cavity. Ectopic pregnancies occur in 1-2 percent of all pregnancies. Ectopic pregnancies require close physician supervision. Some ectopics can be treated with medications, but some cases require emergency surgical care.
Ectopic pregnancies used to be more common in women receiving fertility treatment, but that trend has been reversed in recent years thanks to developments in embryo transfer methods and the number of embryos transferred at one time. The rate of ectopic pregnancies in patients treated with advanced reproductive technologies is less than 1 percent.
Adnexal torsion (ovarian twisting)
This is a rare complication that occurs in 1 percent of cycles. As the ovaries enlarge, they may twist, cutting off their blood supply and causing severe abdominal pain, nausea, vomiting and sometimes low grade fevers. Treatment involves surgical untwisting of the ovary.
Egg retrieval risks
Internal bleeding is a rare complication. However, any time a needle is placed into the pelvis (such as with an egg retrieval) blood vessels can be lacerated. Usually this bleeding spontaneously resolves, but in extremely rare cases (less than 1 percent) surgical therapy may be required to stop internal bleeding.
Damage to surrounding organs including the bowel and bladder are possible, though very rare. Pelvic infection may also occur, but is rare as well. It occurs more commonly among women with ovarian endometriomas (a type of ovarian cyst) that are drained at the time of egg retrieval. Pelvic discomfort is common after the procedure.
Not a known risk: ovarian cancer
Risks to the baby
The exact risks to children conceived after IVF are difficult to study and quantify. While some studies illustrate a higher risk to children born after IVF cycles, it is possible that these risks are due to the underlying state of infertility and are not exclusively due to the IVF treatment itself.
The most common risk to babies born after IVF is related to multiple gestation, which can cause premature birth. Other complications include a small increase in the risk of birth defects and pregnancy complications as described below.
Multiple gestation resulting in preterm birth
The degree of impairment due to preterm birth is related to the timing of the birth; children born more prematurely have more severe complications and greater risk of long-term impairment. Prematurity may result in complications involving:
- Pulmonary immaturity and difficulty breathing
- Cerebral hemorrhage (bleeding in the brain, possibly causing long-term handicaps)
- Intestinal infection and inflammation (necrotizing enterocolitis)
- Visual impairment including blindness
- Poor growth.
The baseline risk of a major birth defect for all children in the United States is 3-5 percent. IVF pregnancies have an approximately 1-2 percent higher chance of having a major birth defect (predominately cardiovascular and musculoskeletal abnormalities).
The cause for this increased risk is unknown, but theories include:
- Underlying cause of infertility predisposes to abnormalities
- IVF treatment may pose risk
- Pregnancies derived by IVF are scrutinized more closely, so people are more likely to detect abnormalities in this population (ascertainment bias).
Recent attention has focused on the increased incidence of gene imprinting disorders (including Angelman syndrome and Beckwith-Wiedemann syndrome) after IVF cycles. However, it is unclear whether these disorders are present in the infertile couple or are induced by the IVF treatment.
Abnormal gene imprinting may lead to aberrant gene expression and subsequent birth defects or cancer later in life. Theories of how IVF may induce such gene changes include changes induced by the extended embryo culture.
It is important to remember that there is no conclusive evidence that IVF causes these disorders, and that overall, an exceedingly small number of infants are actually affected with these disorders.
Infants born as the result of IVF cycles involving intracytoplasmic sperm injection (ICSI) have been shown in some studies to also have an increased risk of birth defects, particularly a condition known as hypospadias that involves an abnormal location of the urethra on the penis. This can easily be corrected in childhood with urologic surgery.
Again, this risk is not dramatically higher than the risk for the general population, and a small number of infants are actually affected with these disorders. Infants born after ICSI cycles also demonstrate a higher incidence of karyotype (number of chromosomes) disorders, which are more common among men with abnormal semen characteristics who require ICSI for successful fertilization.
As most men with such sperm abnormalities are otherwise completely healthy and normal, it is impossible to know if such inherited genetic abnormalities pose any health risks to offspring. Continued research over time may help resolve this controversy.
Pregnancy complications for the baby
Pregnancies achieved through IVF have complications more frequently than pregnancies conceived naturally. Controversy exists regarding whether they are caused by the infertility itself or the fertility treatment. Complications include slight increases in:
- Perinatal mortality
- Low birth weight (after birth, growth and intelligence are normal)
- Preterm delivery.
Other conditions that may occur more commonly after IVF cycles include gestational diabetes, preeclampsia and placenta previa, all of which may pose risks to the fetus. However, current data is unclear about the cause and prevalence of these complications among infertile women after IVF.
In summary, research demonstrates a small but real increase in risk of adverse outcomes during pregnancy after IVF. It is important to remember that these risks are small and that the development of IVF and ICSI has allowed countless couples to conceive and deliver healthy children.
Which IVF strategy is right for you?
Ten couples with the same circumstances may all make very different decisions. It is important to talk to a physician who can help patients determine which treatment is the best option. Patients often have the option to pursue standard IVF, mini-IVF or natural cycle IVF depending on several factors. For patients simply looking for the quickest route to pregnancy, standard IVF may be best.
