The advantage of using a diaphragm or cervical cap primarily lies in its ability to provide protection against some sexually transmitted diseases (STDs). While these contraceptive devices serve the main purpose of preventing pregnancy by creating a physical barrier to sperm, they can also reduce the risk of certain infections by minimizing direct contact between bodily fluids during intercourse. This barrier can potentially lower the transmission rates of STDs such as gonorrhea and chlamydia, though it's important to note that these devices do not offer comprehensive protection like condoms, which are specifically designed to minimize STD transmission.

When considering the other options, the requirement for a prescription can vary based on local regulations and availability of the devices, which makes the second option less universally applicable. Increasing blood circulation and inducing a regular menstrual cycle are not effects associated with diaphragms or cervical caps; these devices do not have physiological impacts on circulation or menstrual cycle regulation. Thus, the focus on their role in STD protection highlights a significant advantage of these contraceptive methods.
