Are There Any Health Risks with IVF?

In vitro fertilisation (IVF) has brought hope to millions of couples struggling with infertility. It’s a widely used assisted reproductive technology (ART) that helps women conceive by fertilising eggs with sperm outside the body. While IVF has enabled many families to grow, it is not without its challenges. Like any medical procedure, it carries potential health risks for both the woman and the baby. Understanding these risks is essential for anyone considering or undergoing IVF treatment.

What is IVF and How Does It Work?

IVF involves several stages—ovarian stimulation, egg retrieval, fertilisation in the lab, embryo culture, and embryo transfer. It may also include procedures like intracytoplasmic sperm injection (ICSI), genetic testing, or freezing of embryos for future use. While it’s often successful, IVF is intensive and can place physical and emotional strain on those involved.

Short-Term Health Risks of IVF for Women

Most women tolerate IVF procedures well, but short-term side effects may occur during the ovarian stimulation and egg retrieval phases. Common short-term risks include:

• Ovarian Hyperstimulation Syndrome (OHSS): A condition where the ovaries swell and become painful due to excessive response to fertility drugs. Symptoms include bloating, nausea, vomiting, and abdominal discomfort. Severe cases may require hospitalisation.
• Injection site reactions: Bruising, redness, or irritation at the site of hormone injections.
• Mood swings: Hormonal fluctuations may affect emotional stability and lead to irritability, depression, or anxiety.
• Pelvic pain or cramping: Especially after egg retrieval or embryo transfer.

Long-Term Health Risks of IVF for Women

Although long-term risks are relatively rare, ongoing studies are examining the potential consequences of repeated IVF cycles and hormone exposure. Key concerns include:

• Increased risk of certain cancers: Some studies suggest a possible link between IVF hormones and ovarian, endometrial, or breast cancer. However, research is inconclusive, and more data is needed.
• Multiple pregnancies: IVF increases the likelihood of twins or triplets, which in turn elevates health risks like gestational diabetes, hypertension, and premature labour.
• Complications in pregnancy: Women who conceive through IVF may face higher chances of placenta previa, preeclampsia, and caesarean delivery.

Health Risks of IVF for Babies

Babies conceived through IVF are generally healthy. However, studies show a slight increase in certain risks compared to naturally conceived children:

• Low birth weight: More common in babies born through IVF, particularly in multiple pregnancies.
• Preterm birth: IVF pregnancies have a higher likelihood of delivering before 37 weeks.
• Birth defects: Some studies indicate a minor increase in congenital abnormalities, though most IVF babies are born healthy.
• Epigenetic changes: Early evidence suggests IVF may alter gene expression, though the long-term impact is not fully understood.

Risks Associated with Frozen Embryo Transfer

Many clinics now use frozen embryo transfer (FET) instead of fresh transfers. While FETs may reduce some maternal risks, research indicates a slightly higher risk of:

• Large for gestational age (LGA) babies
• Pre-eclampsia
• Placental complications

Despite these concerns, FETs offer the benefit of allowing the uterus to return to a more natural hormonal state before transfer, improving implantation and success rates.

Emotional and Mental Health Risks

Undergoing IVF can take an emotional toll. The financial cost, physical strain, and uncertainty of outcomes can be stressful. Women may experience:

• Anxiety before each IVF cycle or embryo transfer
• Depression, particularly if cycles are unsuccessful
• Relationship strain between partners
• Fear of failure or guilt

Psychological counselling and support groups can be beneficial in managing these effects. Many clinics now offer mental health support as part of IVF care.

Factors That Increase IVF Risks

Certain factors may increase the likelihood of complications during or after IVF:

• Advanced maternal age (especially over 40)
• Polycystic ovary syndrome (PCOS)
• Endometriosis
• Multiple previous IVF cycles
• Pre-existing health conditions (e.g., diabetes, obesity)

Discussing these risk factors with a fertility specialist can help develop a personalised treatment plan that minimises complications.

How to Minimise Health Risks During IVF

While risks exist, there are strategies that can help reduce them:

• Use single embryo transfer (SET) to reduce multiple pregnancies.
• Closely monitor hormone levels to prevent OHSS.
• Choose a qualified and experienced IVF clinic with a good success rate.
• Follow a balanced diet and maintain a healthy weight.
• Manage stress through yoga, mindfulness, or counselling.

Case Example: Learning from Sarah’s Experience

Sarah, a 34-year-old woman with PCOS, underwent her first IVF cycle and experienced OHSS. She had bloating and abdominal pain, requiring a short hospital stay. With her doctor’s guidance, her second cycle was adjusted with lower hormone dosages and resulted in a successful pregnancy. Today, Sarah advises women to stay informed and never ignore side effects.

Conclusion

IVF is a remarkable advancement in reproductive medicine, offering hope to individuals and couples struggling with infertility. However, it’s not risk-free. Understanding the potential health complications for both mother and baby is key to making informed decisions. With the right medical support, personalised care, and ongoing research, many of these risks can be mitigated, paving the way for a healthy pregnancy and birth.

FAQs About IVF Risks

Q1. Is IVF safe for all women?

While generally safe, IVF may pose risks depending on a woman’s age, health, and fertility condition. Consulting a specialist is essential.

Q2. Can IVF cause cancer?

Some studies suggest a possible link between IVF hormones and certain cancers, but evidence remains inconclusive. Regular monitoring is advised.

Q3. Are IVF babies healthy?

Most IVF babies are healthy, although there's a slight increase in low birth weight and preterm delivery compared to natural conception.

Q4. What is OHSS, and is it common?

Ovarian Hyperstimulation Syndrome occurs when the ovaries overreact to fertility drugs. Mild cases are common; severe cases are rare.

Q5. How can I reduce the risks of IVF?

Choose a reputable clinic, opt for single embryo transfer, maintain a healthy lifestyle, and follow your doctor’s guidance closely.
