What substance is primarily responsible for causing menstrual cramps or dysmenorrhea?

• A. Estrogen
• B. Progesterone
• C. Prostaglandins
• D. Oxytocin

Answer: (C)

Prostaglandins are the primary substances responsible for causing menstrual cramps, also known as dysmenorrhea. These are lipid compounds that have hormone-like effects in the body and play a significant role in the contraction of uterine muscles during menstruation. When menstruation begins, the lining of the uterus releases prostaglandins, leading to increased uterine contractions. While some contraction is necessary for shedding the uterine lining, high levels of prostaglandins can lead to excessive contractions, resulting in pain and discomfort associated with menstrual cramps. Additionally, prostaglandins can also lead to other systemic symptoms such as nausea, headaches, and diarrhea, as they influence various bodily systems. Understanding the role of prostaglandins in menstrual physiology is critical for developing effective management strategies for women experiencing dysmenorrhea.
