👉 A hymenoid is a type of hair follicle that grows in the vagina. It's located on the bottom of the vagina, near the opening called the vaginal canal. This structure helps to keep the vagina dry and prevents bacteria from getting into the vagina. The hymenoid is not part of the reproductive system, but it plays an important role in the health and function of the vagina. It helps to protect the vagina from infection and can also help to prevent the spread of sexually transmitted infections
