Embarking on the journey toward parenthood is a time of hope and anticipation, especially for those navigating the challenges of infertility. Advances in fertility treatments, such as in vitro fertilization (IVF), offer promising pathways to achieving this dream. While these advancements have revolutionized reproductive care, knowing and understanding how to manage potential risks is important, ensuring a safe and informed journey.

One such risk, Ovarian Hyperstimulation Syndrome (OHSS), although rare, requires awareness. This condition, linked with fertility treatments, involves the ovaries responding more vigorously than expected. However, with expert care and personalized treatment plans, the likelihood of experiencing severe OHSS is significantly minimized, ensuring that the path to parenthood remains hopeful and secure.

What is Ovarian Hyperstimulation Syndrome (OHSS)?

Ovarian Hyperstimulation Syndrome (OHSS) is characterized by overstimulation of the ovaries and triggered by a hormone called human chorionic gonadotropin (hCG) during fertility treatments. HCG’s use is for the final maturation of eggs in the ovaries before they are retrieved for fertilization in the lab.

When the ovaries are overstimulated, they can swell and become very vascular. Intravascular fluid can be lost through the ovary into the abdomen, pelvis, and other parts of the body, leading to symptoms such as bloating, abdominal pain, nausea, vomiting, and weight gain.

It’s essential to emphasize that severe OHSS is rare, affecting a very small percentage of individuals undergoing treatments like IVF.

Our clinic prioritizes patient education on OHSS symptoms to ensure early detection and management. Symptoms range from mild bloating and discomfort to more pronounced signs warranting medical attention. Early recognition of these symptoms allows for swift and effective interventions, mitigating discomfort and preventing progression.

Navigating OHSS Risk with Expertise and Care

The incidence of OHSS is low, with severe cases being extremely rare. Key factors such as age, specific medical conditions like PCOS, and the nature of the fertility treatment can influence risk levels. It affects approximately 3-6% of people who undergo IVF. Severe cases happen in less than 1% of people receiving fertility treatments.

A person is more likely to develop OHSS if they:

  • trigger with high doses of hCG
  • have had precious episodes of OHSS
  • are younger than 35
  • have a low BMI
  • have a high starting antral follicle count
  • develop a large number of ovarian follicles or have high estrogen levels during stimulation
  • have polycystic ovary syndrome (PCOS)

At RMA, our approach is rooted in prevention and personalized care. We meticulously tailor treatment protocols to each patient’s unique profile and follow you closely during your IVF cycle, significantly reducing the risk of OHSS.

To ensure safety and comfort, we employ innovative strategies for those at higher risk, including alternative medications and close monitoring. Our proactive measures, coupled with the latest advancements in fertility science, have made OHSS more manageable and less of a concern for aspiring parents.

Long-term Implications of OHSS

While OHSS typically resolves within a few weeks, there are potential long-term effects to consider, especially in cases of severe OHSS.

These effects include:

  • Ovarian enlargement: The ovaries may remain enlarged for several months after severe OHSS, causing abdominal discomfort and bloating.
  • Ovarian torsion: In rare cases, the enlarged ovaries can twist, leading to a serious condition called ovarian torsion.
  • Recurrence of OHSS: People who have experienced OHSS in the past are at an increased risk of developing it again in future fertility treatments.
  • Impaired fertility: Severe OHSS can potentially affect future fertility. However, the extent of this damage varies depending on the severity of the OHSS episode.

Embracing a Proactive and Patient-Centered Approach

Our commitment to your safety and well-being is paramount. We integrate the latest research and clinical guidelines into our practice, ensuring every patient receives the most advanced and personalized care possible, including:

  • Personalized Treatment Plans: Tailoring stimulation protocols to match your unique physiological response and following you closely during your cycle, minimizing the risk of overstimulation.
  • Innovative Approaches: Utilizing alternative methods for those at increased risk, offering safer pathways to successful pregnancy outcomes.
  • Empowering Through Education: Providing comprehensive information and support to navigate your treatment with confidence and peace of mind.

Symptoms of Ovarian Hyperstimulation Syndrome

The symptoms of OHSS vary depending on the severity of the condition.

Symptoms of mild OHSS include:

  • abdominal pain
  • bloating
  • nausea
  • weight gain

Symptoms of moderate to severe OHSS include:

  • rapid weight gain (more than 10 pounds in three to five days)
  • severe nausea and vomiting
  • diarrhea
  • thrombosis (blood clots in the lungs or legs)
  • shortness of breath
  • severe abdominal swelling
  • severe abdominal pain
  • decreased urine output
  • kidney failure

Diagnosis and Medical Evaluation

Diagnosis of OHSS typically involves a physical exam, evaluation of symptoms, monitoring of hormone levels, and ultrasound imaging, among other tests.

Laboratory Tests

A fertility specialist may order the following laboratory tests to diagnose and evaluate OHSS:

Imaging Tests

  • Abdominal ultrasound: This non-invasive imaging test uses sound waves to create detailed images of the ovaries and surrounding organs. An abdominal ultrasound can help identify enlarged ovaries and fluid buildup in the abdomen, both of which are signs of OHSS.
  • Vaginal ultrasound: Similar to an abdominal ultrasound, a vaginal ultrasound provides a more detailed view of the ovaries and other pelvic structures. It's beneficial for detecting early signs of OHSS, such as follicular enlargement and fluid buildup.

Treatment Options & Prevention

In most cases, OHSS can be effectively managed with conservative treatment measures focused on symptom relief and supportive care.

Treatment for Mild to Moderate OHSS

Treatment options for mild to moderate OHSS may include:

  • Increased fluid intake: Staying hydrated is crucial for maintaining fluid balance and preventing complications. Drink plenty of fluids, especially electrolyte-rich fluids, throughout the day.
  • Close monitoring: Regular check-ups are essential to track the progression of OHSS and ensure timely intervention if needed. Monitoring may include measuring weight, abdominal circumference, fluid intake, and output.
  • Symptom relief medications: Over-the-counter pain relievers, such as ibuprofen or acetaminophen, can help alleviate discomfort associated with OHSS. Treatment with a medication called Cabergoline following trigger may help reduce occurrence.
  • Anticoagulants: In some instances, fertility specialists may prescribe a blood clot prevention medication to reduce the risk of thrombosis, a potential complication of severe OHSS.

Frozen Embryo Transfer Implications

Pregnancy with a fresh embryo transfer can exacerbate the symptoms of OHSS for weeks. In addition, fresh embryo transfer has been demonstrated to have lower pregnancy rates than frozen embryo transfer and does not allow for Preimplantation Genetic Testing for Aneuploidy (PGT-A). At RMA, all of our transfers are done in a frozen embryo transfer cycle to increase your chance of success and lower your risk of OHSS.

By implementing these preventive measures, RMA demonstrates a commitment to minimizing the risk of OHSS and providing comprehensive care for all patients undergoing fertility treatments. Our proactive approach empowers patients to make informed decisions about their treatment plans and promotes a positive and safe fertility journey.
