What is the leading cause of infertility in women?

• A. Endometriosis
• B. Polycystic Ovary Syndrome (PCOS)
• C. Ovulatory disorders
• D. Age-related factors

Answer: (B)

Polycystic Ovary Syndrome (PCOS) is indeed a prominent cause of infertility in women. It affects the hormonal balance and can lead to irregular menstrual cycles or anovulation (the absence of ovulation), both of which can significantly hinder a woman's ability to conceive. PCOS is characterized by an imbalance of reproductive hormones, which can contribute to various metabolic issues and affect ovarian function.

While endometriosis, ovulatory disorders, and age-related factors are also significant causes of infertility, PCOS is frequently identified as the most common endocrine disorder affecting women of reproductive age, thus leading many professionals to highlight it as a leading cause in discussions surrounding infertility. The prevalence of PCOS in the general population and its direct impact on ovulation and fertility makes it a critical focus in understanding women's reproductive health issues.
