Which fibroid subtype is most strongly associated with heavy menstrual bleeding and infertility due to distortion of the uterine cavity?

• A. Subserosal
• B. Submucosal
• C. Intramural
• D. Pedunculated

Answer: (B)

The main idea is that fibroids that grow into the uterine cavity disrupt the lining and architecture where pregnancy occurs. When a fibroid protrudes into the endometrial cavity, it distorts the cavity and interferes with normal shedding, which leads to heavy menstrual bleeding. It also creates an inhospitable environment for implantation, contributing to infertility. Other fibroid types primarily affect the outside of the uterus or lie within the wall and tend to cause bulk or pressure symptoms rather than distortion of the cavity, so their impact on heaviness of menses and fertility is less pronounced.
