What is a notable feature of Polycystic Ovarian Syndrome (PCOS)?

Polycystic Ovarian Syndrome (PCOS) is characterized by the presence of multiple cysts in the ovaries, which can indeed lead to dysfunction in ovulation. In this condition, hormonal imbalances disrupt the normal ovulation process, resulting in multiple follicles developing in the ovaries; however, these follicles do not mature fully and thus do not release eggs for ovulation. This anovulation is a central feature of PCOS, contributing to symptoms such as irregular menstrual cycles, infertility, and other metabolic issues.

The other options pertain to different medical conditions; for example, the abnormal opening between two organs is related to fistulas, and the growth of endometrial tissue outside the uterus is associated with endometriosis. Enlarged prostate gland due to cell replication is indicative of benign prostatic hyperplasia or prostate cancer, neither of which has any relevance to PCOS. Therefore, the correct choice highlights the specific reproductive dysfunction that is a hallmark of Polycystic Ovarian Syndrome.
