Final answer:
The symptoms of a follicular ovarian cyst are usually asymptomatic but can include menstrual irregularities and dyspareunia. Acute pelvic pain can also occur but fever and postmenopausal bleeding are not typical symptoms.
Step-by-step explanation:
The signs and symptoms of a follicular ovarian cyst can vary, but they are often asymptomatic, meaning they present no noticeable symptoms. However, when symptoms do occur, they may include menstrual irregularities, such as a delayed or irregular period, and pain during intercourse, also known as dyspareunia. Although you provided multiple choice options, based on the information, the most fitting answer would be 'menstrual irregularities and dyspareunia' (option c). Some ovarian cysts can also cause acute pelvic pain, but typically that symptom alone would not specifically indicate the presence of a follicular ovarian cyst without additional context.
