The opening of the vagina is protected by the labia majora and the vulva. The vulva is part of the external organs of the female genitalia.

The vagina is full of nerve endings, which allows the sensation of pleasure during sexual intercourse.

The parts of the vagina are:

  • Clitoris : female sexual organ related to the woman’s sexual term.
  • Hymen : membrane located at the entrance to the vagina. Most of the time, the hymen is broken during the first sexual intercourse.
  • Vaginal wall : the vagina is formed by two walls, which have three layers: the mucosa, the muscle and the adventitia.
  • Bartholin’s glands : located on both sides of the vaginal walls, they are responsible for secreting a clear, viscous and lubricating liquid, important at the time of sexual intercourse.
  • Cervix or cervix : located at the bottom of the vagina, it represents the lower portion of the uterus and where its opening is located.


  • The vagina can expand up to 200% during sexual arousal and childbirth. The elasticity of the vagina is lost with age.
  • The shape of the vulva varies from woman to woman.
  • The vagina has natural mechanisms to keep itself clean.
  • Over-cleaning the female genitalia can make her more vulnerable to infections.
