The female reproductive organs include several key structures, such as the ovaries, uterus, vagina, and vulva. These organs are involved in fertility, conception, pregnancy, and childbirth.

The reproductive organs also have a significant influence on other aspects of health. For example, the ovaries create hormones that impact bone density, cholesterol levels, heart health, and mood.

In this article, we will look at the anatomy of the female reproductive organs in detail, including what they do and how they work.

The female reproductive system is a group of organs that work together to enable reproduction, pregnancy, and childbirth. It also produces female sex hormones, including estrogen and progesterone.

The system consists of organs and tissues inside the body and some that are visible outside the body. The internal organs include:

Another organ, the clitoris, extends both inside and outside the body. The external area surrounding the vagina is the vulva.

Not everyone who is assigned female at birth has all of these organs. Sometimes, people are born without some parts or with a mixture of female and male characteristics. This is known as intersex.

Some people also undergo procedures to remove some parts of the reproductive system. Some of these procedures take place for medical reasons, while others are the result of harmful cultural practices, such as female genital mutilation.

Most females have two ovaries, one on each side of the uterus. They are about the shape and size of an almond and have two key functions: producing hormones and releasing eggs.

At birth, two ovaries contain approximately 700,000 oocytes, which are immature eggs. When a person reaches puberty, these eggs begin to develop and mature inside the ovary follicles. Around once each month, the ovaries release a mature egg.

This process is known as ovulation, and it is part of the menstrual cycle. It is also what makes pregnancy possible.

The hormones the ovaries produce regulate the menstrual cycle. They also:

The fallopian tubes are passageways that carry eggs toward the uterus. They consist of several parts:

When an ovary releases an egg, fluid and the fimbriae propel it toward the fallopian tube opening. Once inside, the cilia move the egg toward the uterus. This journey takes about 7 days.

During this time, it is possible for sperm to fertilize the egg if a person has sexual intercourse. Most fertilization happens in the fallopian tubes.

The uterus is an organ that is about the shape and size of a pear. It is also known as the womb. It consists of muscular walls and a lining (endometrium) that grows and diminishes with each menstrual cycle.

After ovulation, the endometrium gets thicker in preparation for a fertilized egg. If not fertilized, the egg dies, and the lining of the womb sheds after around 2 weeks. The lining breaks down into blood, which then leaves the body through the vagina. This is menstruation, also called a period.

If an egg does become fertilized by sperm, it will implant into the lining of the uterus and begin to develop. The cells divide and grow, becoming an embryo. Over time, it grows into a fetus, which receives oxygen and nutrients from the placenta via the umbilical cord.

When it is time for the fetus to be born, the uterus begins strong muscle contractions that dilate the cervix and push the fetus out.

The cervix is a narrow structure at the bottom of the uterus. It has several functions:

Below the cervix is the vagina, which is a flexible, tubular structure that connects the internal and external reproductive organs. It sits behind the bladder and in front of the digestive tract.

The vagina allows fluids, such as menstrual blood and discharge, to leave the body. It also allows semen, which contains sperm, to enter the body.

This can happen in several ways, such as during penetrative sex with someone who has a penis, or during artificial insemination. This is a procedure where a doctor inserts semen into the uterus to help someone conceive.

Just inside the body, around the entrance to the vagina, is the clitoris. This organ is most well known for the clitoral glans, which is a small but highly sensitive tissue that sits above the vaginal opening. Most of the clitoris is actually internal.

The clitoral glans is at the top of the clitoris. From there, the clitoris splits into two parts that extend down either side of the vagina. It is around 5 inches (12.7 centimeters) long and consists of spongy tissue that contains thousands of nerve endings.

The clitoris responds to sexual stimulation. When a person experiences arousal, it becomes swollen. It is the main organ responsible for female orgasms.

The vulva is the external part of the female reproductive system. It includes the:

The female reproductive organs include an array of parts that influence health throughout a persons life. The reproductive system undergoes significant changes during the menstrual cycle, which starts during puberty and ends with menopause. If a person becomes pregnant, it changes further to accommodate a growing fetus.

Female reproductive anatomy also influences sexual well-being, and creates hormones that regulate a wide variety of functions around the body.
