IVF is a safe and, in many ways, routine method of treating infertility. Even so, it naturally brings many questions and concerns into the lives of couples. What risks after IVF should you be aware of? Which symptoms are normal, and when is it better to pay closer attention? In this article, we explain what women may encounter — clearly and without fear‑mongering.
What Falls Under the Term “Risks After IVF”
When talking about risks after IVF, everyone tends to imagine something different. Some think of side effects from hormonal medication; others picture concerns about the baby’s health or possible pregnancy complications.
At Prague Fertility Centre, we recognize several potential risks that may appear at different stages of treatment or after it. Not all of them affect every woman, and most are very manageable today thanks to modern medical approaches.
Risks after IVF can be divided into several areas:
- risks associated with ovarian hormonal stimulation,
- risks related to egg retrieval,
- risks after embryo transfer (implanting the cultured embryo into the uterus),
- risks during pregnancy,
- and long‑term risks for the woman and the child.
In the following sections, we look more closely at each of these areas — in context — so you understand what can happen, but also what is very unlikely to occur. We believe this brings peace of mind to many women.
Short‑Term Risks After IVF
Reactions to Ovarian Hormonal Stimulation
Ovarian stimulation is an essential part of IVF treatment. For the body, however, it is an intervention that doesn’t occur in a natural cycle, so it’s normal for the body to respond. The most common symptoms include:
- bloating and pelvic pressure,
- breast tenderness,
- nausea or vomiting,
- mood swings and fatigue.
It’s important to highlight that these symptoms are a normal reaction and not a sign that the treatment is progressing incorrectly.
Ovarian Hyperstimulation Syndrome (OHSS)
One of the less common — but still discussed — risks of hormonal stimulation is ovarian hyperstimulation syndrome (OHSS). This occurs when the ovaries respond too strongly to medication. Symptoms may include:
- significant ovarian enlargement,
- abdominal bloating and discomfort,
- dehydration,
- fluid accumulation in the abdomen,
- difficulty breathing.
In the past, OHSS occurred much more frequently. Between 1982 and 2004, up to 19.6% of women experienced it. The reasons included different stimulation protocols and an emphasis on retrieving as many eggs as possible. Today, the situation is very different. Modern, gentler stimulation plans, careful monitoring, and individualized dosing have made OHSS relatively rare.
Risks After IVF Related to Egg Retrieval
Egg retrieval is often the step women fear most. In reality, it is a short, routine procedure considered very safe. A specialist inserts a thin needle through the vaginal wall and aspirates follicular fluid containing the eggs. The procedure takes 10 – 15 minutes under light anesthesia.
Most women later describe it as much easier than expected. Still, a few mild risks can occur:
- light pelvic or abdominal pain during or after the procedure — manageable with medication,
- injury to the bladder, bowel, or blood vessels — extremely rare; contact your doctor if you experience fever, severe pain, or heavy bleeding,
- pelvic infection after retrieval or transfer — women with a history of pelvic infections are at slightly higher risk.
Risks After Embryo Transfer and in Early Pregnancy
Ectopic Pregnancy After IVF
Compared to natural conception, the risk of ectopic pregnancy is 1 – 2% higher after IVF. It is more common in women with a history of pelvic infections or damaged fallopian tubes. Early ultrasound monitoring is the best prevention — it ensures the embryo is developing in the correct location.
Initially, an ectopic pregnancy feels like a typical pregnancy. However, symptoms such as abdominal pain or cramps, vaginal bleeding, dizziness, or fainting require immediate medical attention — even if the suspicion is slight.
Bleeding During the First Weeks
Bleeding in early pregnancy often causes anxiety. Light spotting or mild bleeding can be related to implantation or hormonal changes and is usually not a reason to fear the worst. Contact your doctor if bleeding continues, becomes heavier, or is accompanied by abdominal pain.
IVF‑Related Risk of Multiple Pregnancy
In the past, multiple pregnancy was a common IVF risk because transferring multiple embryos was standard practice to increase chances of success. However, this also increased health risks for both the woman and the baby.
Today, the situation is very different. Thanks to advanced lab techniques, the best embryo can be selected with much greater precision, and clinics frequently transfer only one embryo, greatly reducing pregnancy‑related complications and providing better conditions for the child.
Congenital Conditions in Children
We also receive questions about congenital conditions and the health of IVF‑conceived children. Data from the Czech Republic show a congenital anomaly rate of:
- 4.22% in spontaneously conceived children,
- 4.54% in children born after IVF.
This difference is not statistically significant. In both groups, the risk is low, and children conceived using assisted reproduction are born healthy. The age of the parents often plays a far more important role in genetic risk than IVF itself.
The “Invisible” Risk: Psychological Burden
The entire assisted reproduction process is physically and emotionally demanding. Women often feel tense while waiting for results, afraid the attempt will fail, or worried that success may never come. Add pressure from relatives or friends and the emotional impact of fertility medications — and it becomes clear how overwhelming the journey can feel.
Emotional well‑being is therefore essential from beginning to end. A calm, safe environment and supportive people not only make the experience more bearable but may even improve treatment outcomes.
