The menstrual cups with the smallest size diameter are recommended for teenagers, as well as menstruating women and girls who are more physically fit, as those with stronger pelvic floor muscles may find a larger cup uncomfortable.
Length also needs to be considered: if a female's cervix sits particularly low, she may want to use a shorter cup.
The menstrual cup is a bell-shaped cup made of rubber (latex), silicone or thermoplastic elastomer (TPE).
It is reusable and designed to last for up to 10 years.
It is worn inside the vagina during menstruation to catch menstrual fluid (blood).Capacity is important to women who have a heavier flow; however, all of the menstrual cups currently available have a larger capacity than a regular tampon.
