A menstrual cup is a menstrual hygiene tool which is inserted into the vagina in the course of menstruation. Its motive is to accumulate menstrual fluid (blood from the uterine lining mixed with different fluids). Menstrual cups are typically product of flexible medical grade silicone, latex, or a thermoplastic isomer. They are formed like a bell with a stem or a hoop. The stem is used for insertion and elimination, and the bell-formed cup seals against the vaginal wall simply below the cervix and collects menstrual fluid. This is unlike tampons and menstrual pads, which take in the fluid rather every four 12 hours (relying on the quantity of float), the cup is eliminated, emptied, rinsed, and reinserted. After every period, the cup requires cleaning. One cup may be reusable for up to 10 years,making their lengthy term value decrease than that of disposable tampons or pads, although the initial price is higher. As menstrual cups are reusable, they generate less strong waste than tampons and pads, each from the goods themselves and from their packaging maximum menstrual cup manufacturers promote a smaller and a larger length. A few menstrual cups are bought colorless and translucent, but several manufacturers also offer coloured cups.
