However, women who undergo IVF may be at a higher risk for some complications during the process or after pregnancy is achieved.
Specifically, the main problems associated with IVF are due to hormonal ovarian stimulation and intrauterine embryo transfer. However, there are also other risks associated with this fertility treatment.
Provided below is an index with the 7 points we are going to expand on in this article.
Risks associated with ovarian stimulation
Controlled ovarian stimulation consists of the administration of hormonal drugs to provoke multiple follicular developments in the woman's ovaries.
If the normal menstrual cycle is to develop a follicle that gives rise to a mature egg, hormonal medication is intended to obtain several eggs that can be fertilized in order to increase the likelihood of pregnancy.
However, both the administration of hormones and the procedure to remove mature eggs (follicular puncture) have certain risks that a woman should be aware of before starting IVF:
- Ovarian hyperstimulation syndrome
- is a very high response of the ovaries to hormone medication. Many follicles develop, the ovaries overgrow and, after ovulation, the fluid contained in the follicles can pass into the abdominal cavity. Symptoms of this are pain and bloating, nausea, diarrhea, weight gain, etc. In severe cases, ascites, tachycardia, and shortness of breath may occur.
- Risks of egg retrieval
- Ovarian Puncture is a simple surgical procedure performed under sedation. The possible side effects of anesthesia are minor discomfort, dizziness or a drop in blood pressure, but nothing more serious. On the other hand, a complication that can arise during the puncture is damage to the pelvic organs, which can cause bleeding or infection.

Embryo transfer and pregnancy
Once the eggs have been fertilized in the laboratory, it is time to transfer the embryos so that they can implant in the mother's uterus and give rise to a pregnancy.
In most countries, however, specialists are allowed to only transfer a maximum of three embryos. The risk of having a multiple pregnancy is still high.
This is what fertility doctor Miguel Dolz confirms:
By law the maximum limit is 3 embryos, generally, we transfer 2, in certain circumstances 3 and we try more and more to transfer only one embryo.
Below, we will discuss this and other pregnancy-related drawbacks of IVF:
- Multiple pregnancy
- since their introduction, assisted reproduction technologies have increased the rate of twin and even triple pregnancies. This fact, added to the age of most IVF patients, means that the risks of pregnancy are higher for both the mother and the babies. IVF-related risk are, for example, premature birth, c-section, fetal death, preeclampsia, etc.
- Pregnancy loss in the first few weeks is something that occurs in about 20% of cases. What happens with IVF is that many more biochemical miscarriages are detected than when they occur in a natural pregnancy, as they can be simply mistaken for menstruation.
- Ectopic pregnancy
- ectopic or extra-uterine pregnancy means when the embryo implants outside the uterus, such as in the fallopian tubes, for example. The risk of this happening after IVF is 2-5%, while in a natural pregnancy it is only 1%. This is due to the embryo transfer into the uterus and the likelihood of damage to the fallopian tubes.

Other possible risks of IVF
Although the most common risks of IVF are usually those mentioned above, any fertility treatment also involves a great deal of stress.
In the case of IVF, this reproductive option can cause emotional and physical stress, but also financial stress. The probability of pregnancy in the first IVF attempt is not assured and sometimes it is necessary to repeat several IVF cycles until pregnancy is achieved. This involves a large financial investment, which can be stressful for patients.
On the other hand, there is the possibility of having to cancel IVF treatment because of a poor response to medication or because viable embryos are not available for transfer, for example. Fertility centres should also inform patients of the possible risk of IVF cancellation before starting treatment.
In any case, the most important thing is to optimise assisted reproduction treatments to minimise the possibility of side effects and complications. In addition, it is essential to follow medical instructions to limit any IVF risks.
FAQs from users
Does IVF increase the risk of preterm labor?
Numerous scientific studies have shown a slightly increased risk of preterm delivery in children conceived by in vitro fertilization (IVF) compared to children conceived naturally.
It is also known that many of the causes of infertility in women who require IVF are the same causes that have a higher risk of preterm delivery. This is the example of diabetes, thyroid problems, alterations in the coagulation system, immune disorders, adenomyosis, fibroids, advanced age, etc.
What other problems can arise during IVF treatment?
Apart from the rather physical risks that may arise during IVF, the psychological and emotional factor is also very present in all assisted reproduction patients. It is possible to suffer strong episodes of stress and anxiety, especially when receiving a diagnosis or a negative result.
On the other hand, financial problems can also arise due to the high cost of fertility treatments. If the treatment is financed, patients may have to spend several months paying for it even if they are not pregnant.
Does in vitro fertilization have any risk for the baby?
There are some studies that claim that children born through IVF have a slightly increased risk of congenital defects: 4.5% compared to 2-3% in the rest of the population. However, it is not proven that this is due to the assisted reproduction technique itself or, instead, to the infertility problems of the parents.
Recently, it has also been shown that children born by assisted reproduction do not necessarily suffer from infertility, since the first IVF child in the world, Louise Brown, was able to become a natural mother in 2006.

Another risk of IVF is the possibility that the cycle may have to be canceled due to various complications that may arise during the treatment. You can find out what they are in the following article: When is IVF canceled?
In the case of transferring more than one embryo after IVF, there is a risk of having a multiple pregnancy with serious consequences for the health of the mother and the future baby. It’s important to know what these are. Find it out in the following article: Risks of multiple pregnancy.
