What is the most common reason for a woman's unexplained infertility?

The most common reason for a woman's unexplained infertility is ovulatory dysfunction. This condition affects the release of eggs from the ovaries, which can significantly impact a woman's ability to conceive. Ovulatory dysfunction can arise from various underlying issues such as hormonal imbalances, polycystic ovary syndrome (PCOS), or thyroid disorders, among others. These factors can disrupt the regularity of a woman’s menstrual cycle and affect ovulation, leading to difficulties in conceiving.

Ovulatory dysfunction is frequently encountered in clinical settings, making it a primary concern when evaluating a patient with infertility. The identification and assessment of ovulatory patterns are critical steps in infertility workups, as they can determine the appropriate treatment strategies to enhance the chances of conception.

Other causes of female infertility, such as fallopian tube blockage, male factor infertility, and endometriosis, also contribute to infertility but are less frequently the underlying cause in women overall when broad populations are considered. While they are significant considerations in specific cases, ovulatory dysfunction remains the leading cause in general assessments of unexplained infertility among women.
