Female reproductive anatomy includes external structures, known together as the vulva, and internal organs: the vagina, cervix, uterus, fallopian tubes, and ovaries. Understanding female reproductive system anatomy helps you recognize what is normal for your body and know when to talk with a healthcare provider.
External anatomy: the vulva
The vulva is the collective name for the external genitals. It protects the internal organs and plays a role in urination and sexual function. Its main parts include:
- Mons pubis — the rounded, fatty area over the pubic bone.
- Labia majora — the outer folds of skin that enclose and protect the other external structures.
- Labia minora — the inner folds, just inside the labia majora.
- Clitoris — a small, sensitive structure at the top of the vulva, where the inner folds meet.
- Vaginal opening and urethral opening — the entrance to the vagina and the opening through which urine leaves the body.
Vulvas differ greatly in color, size, and shape from person to person, and this variation is normal. For a closer look at the terms people often mix up, see vulva vs. vagina: what's the difference and clitoris anatomy explained.
Internal anatomy: the reproductive organs
The internal organs sit within the pelvis and work together across the menstrual cycle and pregnancy.
The vagina
The vagina is a muscular canal that connects the vulva to the cervix. It is elastic and can change shape, and it serves as the passage for menstrual flow leaving the body and for a baby during vaginal birth. The vagina is self-cleaning and maintains a slightly acidic environment that helps limit harmful bacteria.
For more on these everyday functions, see vaginal discharge: what is normal and understanding vaginal pH.
The cervix
The cervix is the lower, narrow part of the uterus that connects it to the vagina. It has a small central opening that allows menstrual blood to pass out and sperm to pass in, and it widens significantly during childbirth. Learn more in the cervix explained.
The uterus
The uterus is a hollow, pear-shaped organ that sits in the pelvis between the bladder and the rectum. Its thick, muscular wall can stretch to hold a developing pregnancy and contract during labor and menstrual periods.
The uterus has two main regions:
- Corpus (body) — the larger upper part that expands during pregnancy.
- Cervix — the lower part that opens into the vagina.
Each month, the inner lining (the endometrium) thickens in response to hormones. If pregnancy does not occur, this lining sheds as a menstrual period.
The fallopian tubes
The two fallopian tubes extend from the upper corners of the uterus toward the ovaries. They provide the pathway for an egg to travel from the ovary to the uterus, and they are usually where fertilization, if it happens, takes place.
The ovaries
The two ovaries sit on either side of the uterus. They have two key jobs:
- Storing and releasing eggs. Roughly once per cycle, an ovary releases an egg in a process called ovulation.
- Making hormones. The ovaries produce estrogen and progesterone, which regulate the menstrual cycle and affect bone, mood, and many other systems.
What is normal, and when to see a provider
Reproductive anatomy varies widely, and most differences in size, shape, and appearance are normal and healthy. Still, certain changes are worth discussing with a clinician.
Consider booking an appointment if you notice:
- Unusual or persistent pelvic pain.
- A noticeable change in vaginal discharge, including a new odor, color, or itching.
- Bleeding between periods or after menopause.
- A lump, sore, or new growth on the vulva.

The bottom line
Female reproductive anatomy combines external structures (the vulva) with internal organs (the vagina, cervix, uterus, fallopian tubes, and ovaries) that work together for menstruation, sexual function, and pregnancy. Bodies differ, and most variation is normal. If you notice persistent pain, unusual bleeding, or changes that concern you, talk with a healthcare provider.
