PCOS and Infertility: Causes, Symptoms, and Treatment

Introduction

Polycystic Ovary Syndrome (PCOS) is a complex hormonal condition that affects a significant percentage of women in their reproductive years and is one of the leading causes of infertility globally. This disorder impacts various aspects of a woman’s health, including her menstrual cycle, hormonal balance, ability to conceive, and long-term metabolic health. The hormonal imbalance typically involves an overproduction of androgens (male hormones) and a disruption in the ovulation process. Women with PCOS may have enlarged ovaries with small cysts on the outer edges, which is where the condition gets its name.

At National IVF Center, Kathmandu, Nepal, we encounter PCOS regularly in our fertility patients. The condition is particularly common among Nepali women, with studies such as the one conducted in Janakpur indicating that 7.3% of infertile women meet the Rotterdam criteria for PCOS. Other significant findings include 13.95% showing signs of oligo/anovulation, 6.47% with hirsutism, and 17.94% with polycystic ovaries identified via transabdominal scans.

Understanding PCOS is essential for women facing fertility challenges. The condition is not just a reproductive disorder but a multifaceted health issue that requires comprehensive diagnosis and individualized treatment. With increasing rates among women under 35 in Nepal, early intervention and awareness are more crucial than ever.

 

Causes of PCOS

Though the exact cause of PCOS is not yet fully understood, several interrelated factors have been identified as contributors to its development:

1. Insulin Resistance Many women with PCOS have insulin resistance, meaning their body’s cells do not respond properly to insulin. This causes insulin levels to rise, which in turn can trigger the ovaries to produce more androgens. High androgen levels interfere with the normal development of ovarian follicles and hinder ovulation.
   
   
2. Increased Androgen Levels Elevated androgens, or male hormones, are one of the hallmarks of PCOS. These hormones can prevent the ovaries from releasing an egg during each menstrual cycle and cause symptoms such as acne and hirsutism (excess hair growth).
   
   
3. Genetic Predisposition PCOS often runs in families, suggesting a genetic component. Women with a mother or sister who has PCOS are more likely to develop the condition themselves. This hereditary link further emphasizes the need for early screening among at-risk individuals.
   
   
4. Obesity and Lifestyle Factors Being overweight or leading a sedentary lifestyle can worsen insulin resistance and hormonal imbalances. While obesity doesn't cause PCOS, it can make its symptoms more severe and complicate fertility treatment.

 

Symptoms of PCOS

PCOS presents with a variety of symptoms, which can differ widely between individuals. The most common include:

1. Irregular Menstrual Cycles Women with PCOS often experience missed periods, infrequent periods, or prolonged cycles. This irregularity stems from the lack of ovulation, which disrupts the natural hormonal rhythms of the menstrual cycle.
   
   
2. Hirsutism and Acne Elevated levels of androgens cause male-pattern hair growth on the face, chest, and back. Acne, particularly along the jawline, is also common. These physical symptoms can significantly affect self-esteem and mental health.
   
   
3. Weight Gain and Difficulty Losing Weight Many women with PCOS gain weight easily and struggle to lose it, especially around the abdomen. This type of weight gain is closely linked with insulin resistance and increases the risk of diabetes and cardiovascular diseases.
   
   
4. Thinning Hair and Hair Loss In contrast to excess body hair, women with PCOS may also notice thinning hair on their scalp, a condition similar to male-pattern baldness.
   
   
5. Infertility Lack of ovulation is a primary cause of infertility in women with PCOS. Without regular ovulation, the chances of releasing a viable egg each month are significantly reduced.

 

Diagnosis of PCOS

Diagnosis typically involves a combination of clinical evaluation, medical history, physical examination, and diagnostic testing:

1. Ultrasound A pelvic ultrasound checks for the presence of multiple small cysts on the ovaries and measures the thickness of the uterine lining. This helps doctors assess ovulatory function and detect abnormalities.
   
   
2. Blood Tests Blood work measures hormone levels, including androgens, LH (luteinizing hormone), FSH (follicle-stimulating hormone), and insulin. It may also include tests for cholesterol, triglycerides, and glucose tolerance.
   
   
3. Physical Examination This includes checking for signs of excess hair growth, acne, and obesity. A detailed menstrual history also provides critical clues to a possible PCOS diagnosis.

 

Complications of PCOS

PCOS doesn’t just affect fertility; it has broader implications for a woman’s health:

1. Type 2 Diabetes Insulin resistance can progress to type 2 diabetes, especially in overweight individuals.
   
   
2. Cardiovascular Disease Elevated cholesterol and blood pressure levels increase the risk of heart disease.
   
   
3. Endometrial Cancer Prolonged absence of menstruation can lead to abnormal thickening of the uterine lining, raising the risk of cancer.
   
   
4. Mental Health Issues The emotional stress of managing PCOS symptoms, combined with body image concerns and infertility, can contribute to anxiety and depression.

 

Treatment Options at National IVF Center

At National IVF Center, we offer a comprehensive range of treatments customized to each patient’s unique condition and reproductive goals:

1. Lifestyle Modifications A healthy diet, regular physical activity, and weight loss can significantly improve symptoms and restore regular ovulation in many women.
   
   
2. Medication
• Ovulation Induction: Drugs like clomiphene citrate and letrozole are commonly used to stimulate ovulation.
  
  
• Insulin-Sensitizing Agents: Metformin helps reduce insulin resistance and may aid in weight loss and ovulation.
  
  
• Hormonal Birth Control: Birth control pills regulate menstrual cycles and lower androgen levels.
  
  
3. Fertility Treatments
• Intrauterine Insemination (IUI): A process in which sperm is inserted directly into the uterus during ovulation.
  
  
• In Vitro Fertilization (IVF): Eggs are retrieved, fertilized in a lab, and implanted into the uterus. IVF is often recommended for patients who do not respond to other treatments.
  
  
4. Ovarian Drilling A minor surgical procedure that reduces androgen-producing tissue in the ovaries, sometimes restoring regular ovulation.
