Menstrual cups are reusable, bell-shaped devices made from silicone, rubber, or latex. They are designed to be inserted into the vagina to collect menstrual fluid during a woman's period. Unlike tampons or pads, which absorb fluid, menstrual cups collect it, making them a more eco-friendly option. They can hold more fluid than traditional products, allowing for longer wear time, typically up to 12 hours. To use a menstrual cup, it must be folded and inserted into the vagina, where it opens and forms a seal against the vaginal walls. After several hours, the cup can be removed, emptied, and cleaned for reuse. Proper care and maintenance can make menstrual cups last for several years, making them a cost-effective choice for menstrual hygiene.
