Overview
The vagina is a muscular canal inside the body that connects the uterus (the womb) to the outside of the body. It is part of the female reproductive system and helps with menstruation, sexual activity, and childbirth.
Vulva vs. vagina
Common terms can be confusing. The vagina is the internal canal. The vulva refers to the external genital structures you can see, including the labia, clitoris, and the opening to the vagina.
Key parts
- Vaginal opening: the entrance to the vagina.
- Vaginal canal: the inside passage that can expand and contract.
- Hymen: a thin membrane at or near the vaginal opening that varies a lot among people.
- Vulva includes labia majora, labia minora, clitoris, and the urethral opening.
What it does
- Allows menstrual blood to leave the body.
- Can accommodate sexual activity and may play a role in childbirth.
- Helps protect against infections through a balanced vaginal environment with the right bacteria.
Puberty and normal changes
During puberty, the body makes estrogen, which causes changes such as vaginal lubrication, hair growth in the pubic area, and the start of menstrual periods. These changes are normal and happen at different times for everyone.
Common health topics
- Hygiene: daily washing with water is enough; avoid rough scrubbing or scented products inside the vagina.
- Discharge: normal discharge varies in color and texture; notify a healthcare provider if you notice persistent itching, strong odor, or unusual changes.
- Infections: yeast infections, bacterial vaginosis, and urinary tract infections can occur; seek care if you have symptoms like itching, burning, or unusual discharge.
- STIs and safe sex: if sexually active, use condoms and get regular health checks; talk openly with partners and a clinician about concerns.
Care and when to seek help
Keep the area clean and dry, wear breathable underwear, and see a healthcare provider if symptoms persist, discharge changes are concerning, or you have questions about puberty or fertility.
Myths and facts
- Myth: The hymen fully blocks the vagina before sex. Fact: Hymens vary widely; there is no single size or shape, and many people have no noticeable hymenal opening before sexual activity.
- Myth: Douching keeps the vagina clean. Fact: Douching can disturb healthy bacteria and cause irritation or infections.
