The female reproductive system is a complex network of organs that play a crucial role in reproduction and hormonal regulation. This system encompasses ovaries and fallopian tubes combined with the uterus and cervix as well as the vagina. 

The organs function together to create eggs and support fertilisation, pregnancy, and menstruation. This guide will teach you about the different parts of the female reproductive system, their functions, and some of the most prevalent disorders affecting women’s reproductive health.

Overview of the Female Reproductive System 

The female reproductive system performs several vital functions related to reproduction. It generates female egg cells, known as ova or oocytes, which are essential for the reproductive process. The system facilitates the transportation of ova to the site of fertilisation, typically occurring within the fallopian tube parts. 

Following fertilisation, the fertilised egg progresses to implantation within the uterine walls, marking the early stages of pregnancy. If neither fertilisation nor implantation takes place, menstruation occurs, involving the periodic shedding of the uterine lining. 

Functions of the Female Reproductive System

The female reproductive system performs several essential tasks related to reproduction and sexual activity. Its primary function involves the creation of ovarian eggs. Ovulation causes the eggs to travel toward the sections of the fallopian tube for potential fertilisation with sperm. 

After fertilisation, the egg reaches the uterus to embed itself in the thickened uterine lining, which develops under hormonal menstrual cycle changes. If implantation occurs, the fertilised egg embeds itself into the enriched uterine lining, allowing for further development. 

In cases where implantation does not take place, the uterine lining is shed during menstruation. The female reproductive system also produces sex hormones that regulate the menstrual cycle, ensuring its continuity. As menopause approaches, the system gradually reduces the production of hormones necessary for maintaining the menstrual cycle. 

During this phase, menstrual cycles may become irregular and eventually cease altogether. A woman is considered menopausal when a full year has passed without experiencing a menstrual period.

Different Parts of the Female Reproductive System

The female reproductive system parts and functions include both external and internal components, each playing a vital role in reproductive health and overall function.

1. External Components 

The external genitals primarily serve to protect internal organs and facilitate the entry of sperm. Collectively known as the vulva, these structures are often mistakenly referred to as the vagina, which is a distinct internal organ.

The vulva primarily consists of the following parts:

• Labia Majora

Known as the ‘large lips’, these structures surround and protect the other external reproductive organs. During puberty, hair growth appears on the surface of the labia majora, which also contains glands that secrete sweat and oil.

• Labia Minora

Often referred to as ‘small lips’, these structures vary in size and shape. Positioned just inside the labia majora, they encircle the vaginal opening (connecting the lower parts of the uterus to the body’s exterior) and the urethral opening (allowing urine to leave the bladder). This delicate skin can easily become irritated or swollen.

• Clitoris

Located at the junction where the labia minora meet, the clitoris is a small, highly sensitive protrusion similar to a penis. A fold of skin called the prepuce covers the clitoris, protecting it while maintaining sensitivity to stimulation.

• Hymen

A thin membrane partially covering or surrounding the vaginal opening, formed during development and present from birth.

• Vaginal Opening

This opening enables the release of menstrual blood and the passage of babies during childbirth. It can accommodate tampons, fingers, sex toys, or a penis during sexual activity.

• Urethral Opening

The urethra opens through a small hole, allowing urine to exit the body.

2. Internal Components 

The internal reproductive organs play essential roles in menstruation, conception, and childbirth:

• Vagina

This muscular canal links the cervix, the lower part of the uterus, to the body’s exterior. The vaginal walls can expand significantly during childbirth and then contract to accommodate smaller objects like tampons. Its mucous membrane lining keeps the area moist.

• Fallopian Tubes

These slender tubes transport eggs from the ovaries to the uterus. Fertilisation typically occurs within the fallopian tubes, where a sperm meets an egg. The fertilised egg then moves into the uterus, embedding itself in the uterine lining.

• Cervix 

Forming the lower uterus parts, the cervix contains a central opening that allows sperm to enter and menstrual blood to exit. During childbirth, the cervix dilates to enable the baby’s passage. Its structure prevents tampons or similar objects from becoming lost inside the body.

• Uterus

A hollow, pear-shaped organ that nurtures a fetus during pregnancy. It comprises two main parts – the cervix and the corpus, with the latter expanding significantly as the fetus develops.

• Ovaries

These small, oval-shaped glands produce both eggs and hormones. Positioned on either side of the uterus, they play a crucial role in the menstrual cycle and reproduction.

Relationship Between Arteries and the Ureter

Sometimes, the ureter may be at risk of injury. The abdominal aorta supplies the ovaries through the ovarian arteries. These ovarian arteries connect with the uterine artery to provide blood to the uterus and the uterine tube. The uterine artery arises from the anterior division of the internal iliac artery, supplying parts of the vagina and ovaries.

During surgery, the ureter can be inadvertently damaged. It originates from the renal pelvis of the kidney and passes posteriorly under the uterine artery, forming the “water under the bridge” relationship, where “water” represents urine and the “bridge” is the uterine artery. 

When performing a hysterectomy, it is crucial to ligate the uterine artery without accidentally ligating or damaging the ureter. The ureter can be identified by its characteristic peristaltic movement.

Common Disorders of the Female Reproductive System

The female reproductive system can experience several disorders, affecting its normal functions and overall health. Some of the most common conditions are as follows:

• Cervical Cancer

Cervical cancer arises when abnormal cells develop in the cervix (the neck of the uterus) and gain the ability to invade surrounding tissues or spread to other parts of the body, such as the abdomen or lungs. 

This type of cancer ranks as the second most common cancer among women globally (following breast cancer) and the fourth leading cause of cancer-related deaths. Symptoms often include unusual vaginal bleeding, pelvic pain, and discomfort during sexual intercourse.

• Vaginitis

Vaginitis refers to inflammation of the vagina, often extending to the vulva. It commonly presents symptoms like yellow, grey, or green vaginal discharge, itching, pain, burning sensations, foul vaginal odour, and discomfort during intercourse. 

Infections account for around 90% of vaginitis cases, primarily caused by the yeast Candida albicans—a condition known as vaginal candidiasis. Other potential culprits include bacteria like Gardnerella vaginalis and single-celled parasites such as Trichomonas vaginalis, typically transmitted through vaginal intercourse.

• Endometriosis

Endometriosis occurs when endometrial tissue, which usually lines the inside of the uterus, grows outside it. This misplaced tissue most commonly forms around the ovaries, fallopian tubes, and uterus, but in rare cases, it can develop in other parts of the body.

Each menstrual cycle triggers bleeding from these abnormal tissue growths, leading to inflammation, pain, and scar formation. Endometriosis rarely occurs before puberty or after menopause.

• Polycystic Ovarian Syndrome (PCOS)

Polycystic Ovarian Syndrome (PCOS) is a reproductive health condition that affects approximately 1 in 10 women of childbearing age. It can disrupt hormone balance and metabolism, leading to various health challenges. Women with PCOS may experience difficulties with fertility, irregular menstrual cycles, and the development of endometrial hyperplasia.

• Interstitial Cystitis (IC)

Interstitial cystitis, commonly referred to as bladder pain syndrome, is a chronic condition that causes persistent pain in the bladder and pelvic area. Women with IC often experience a frequent and urgent need to urinate, accompanied by flare-ups of pelvic discomfort.

FAQs about the Female Reproductive System 

1. What is the cervix?

The cervix forms the narrow, lower part of the uterus and is divided into 2 sections. The upper supravaginal segment connects to the uterine body, while the lower vaginal segment protrudes into the front wall of the vagina. Together with the vaginal canal, the cervix forms the birth canal.

2. What are the functions of the ovaries?

The ovaries in females serve 2 primary functions: endocrine and gametogenic. The endocrine function involves the secretion of essential female hormones, such as oestrogen and progesterone. The gametogenic function is responsible for producing and releasing eggs (ova) needed for reproduction.

3. How can I maintain reproductive health?

Knowing when to seek medical guidance is important for keeping your reproductive system healthy. Consulting a physician when necessary helps prevent potential reproductive health issues.

4. Which organ in the female reproductive system is the most vital?

The uterus plays a crucial role as it is where a fetus develops during pregnancy. It is a muscular, pear-shaped, hollow organ that supports fetal growth.

5. What is the primary function of the female reproductive system?

The main purpose of the female reproductive system is to produce gametes and sex hormones, as well as to support fertilisation and the development of a fetus until birth.
