Topic Area 6 - Reproductive System

What are the five main organs/pairs of organs in the female reproductive system?

• Vagina

• Cervix

• Uterus

• Fallopian tubes

• Ovaries

Where is the vagina located and what is its structure?

• The vagina is a muscular canal situated between the urethra and anus.

• It forms part of the vulva (external female genital organs).

• It can stretch.

What are the reproductive functions of the vagina?

• Receives sperm from the penis during intercourse.

• Provides the exit route for a baby during labour and birth.

• Allows the removal of the uterine lining during menstruation.

• Contains nerves involved in sexual pleasure.

Where is the cervix located?

• The cervix is the lower part (neck) of the uterus.

• It connects the uterus to the vagina.

What are the reproductive functions of the cervix?

• Allows menstrual blood to pass from the uterus into the vagina.

• Allows sperm to enter the uterus.

• Dilates (widens) during labour to allow childbirth.

Where is the uterus located and what is its structure?

• The uterus is a pear-shaped organ.

• It is made of strong muscle.

• It is located in the pelvic cavity behind the bladder and in front of the rectum.

What are the reproductive functions of the uterus?

• Provides the environment for a foetus to develop.

• The muscular walls stretch during pregnancy.

• The muscles contract during labour to push the baby through the birth canal.

Where are the fallopian tubes located?

• There are two fallopian tubes.

• They connect the ovaries to either side of the top of the uterus.

• They are made of muscular tissue.

What are the reproductive functions of the fallopian tubes?

• Fertilisation occurs in the fallopian tubes.

• They transport the fertilised egg to the uterus.

• The fertilised egg implants in the uterus and develops into a foetus.

Where are the ovaries located?

• There are two ovaries.

• They are located at the end of the fallopian tubes.

• They are attached to the uterus by ligaments.

What are the reproductive functions of the ovaries?

• Produce the sex hormones oestrogen and progesterone.

• Produce and mature eggs.

• Release an egg approximately every 28 days during ovulation.

What is the menstrual cycle?

The menstrual cycle is a cycle controlled by sex hormones that prepares the female body for possible pregnancy.

How long is the menstrual cycle usually?

• Approximately 28 days.

• It can be shorter or longer depending on the individual.

When does the menstrual cycle begin?

It begins on the first day of menstruation (when bleeding starts).

What happens during menstruation?

• The lining of the uterus (endometrium) breaks down and is shed.

• This causes menstrual bleeding.

• It lasts approximately 5 days.

What happens during the follicular phase?

• The pituitary gland releases follicle-stimulating hormone (FSH).

• FSH causes an egg to mature inside a follicle in the ovary.

• Oestrogen is released.

• Oestrogen causes the uterus lining to rebuild.

What is the role of follicle-stimulating hormone (FSH)?

FSH stimulates the maturation of an egg inside a follicle in the ovary.

What is the role of oestrogen during the follicular phase?

• Stimulates the uterus lining to rebuild.

• Helps prepare the uterus for possible pregnancy.

What happens during ovulation?

• There is a surge in luteinising hormone (LH) and FSH.

• LH causes the follicle to rupture.

• The mature egg is released from the ovary.

• Ovulation usually occurs around the middle of the cycle.

What is the role of luteinising hormone (LH)?

LH causes the follicle in the ovary to rupture and release the egg.

What happens during the luteal phase?

• LH and FSH levels decrease.

• The follicle becomes the corpus luteum.

• The corpus luteum produces progesterone and oestrogen.

• Progesterone thickens the uterus lining ready for implantation.

What is the role of progesterone?

Progesterone maintains and thickens the uterus lining to prepare for a fertilised egg.

What happens if fertilisation does not occur?

• The corpus luteum stops producing progesterone.

• Oestrogen levels fall.

• The uterus lining breaks down.

• A new period begins.

What is menopause?

Menopause is when a female no longer experiences the menstrual cycle.

What happens biologically during menopause?

• Ovulation stops.

• Periods stop.

• Fertility ceases (the female can no longer become pregnant).

• Oestrogen and progesterone levels decrease.

When does menopause usually occur?

Usually between the ages of 45 and 55.

How is menopause confirmed?

A female is considered to have completed menopause when they have not had a period for approximately 12 months.

What are the symptoms of menopause?

• Hot flushes

• Night sweats

• Difficulty sleeping

• Reduced sex drive

• Palpitations

• Mood swings

Where is the penis located and what is its structure?

• The penis is located externally to the body.

• It has three parts:

  • Root

  • Body

  • Glans

• It contains erectile tissue which fills with blood during sexual arousal.

What is the reproductive function of the penis?

When erect, it allows entry into the vagina during sexual intercourse.

Where is the urethra located?

• The urethra passes through the penis.

• It is part of both the urinary and reproductive systems.

• It connects the bladder to the tip of the penis.

What are the functions of the urethra?

• Allows urine to leave the body.

• Transports semen during ejaculation.

What is the structure and location of the scrotum?

• The scrotum is a skin sac outside the body.

• It contains the testes.

What is the reproductive function of the scrotum?

It keeps the testes outside the body because sperm production requires a temperature lower than body temperature.

Where are the testes located?

The two testes are located inside the scrotum.

What are the functions of the testes?

• Produce sperm.

• Produce testosterone.

What is the role of testosterone?

Testosterone causes the development of male secondary sexual characteristics during puberty, including:

• Growth of body hair

• Deepening of the voice

• Muscle development

Where is the epididymis located?

The epididymis is a long tube located near each testis.

What is the function of the epididymis?

It transports sperm from the testes to the urethra.

Where is the vas deferens located?

The vas deferens is a tube between the epididymis and urethra.

What are the functions of the vas deferens?

• Stores sperm.

• Transports sperm from the epididymis to the urethra.

Where is the prostate gland located?

• The prostate sits at the base of the bladder.

• It surrounds the urethra.

What are the functions of the prostate gland?

• Produces seminal fluid, which carries sperm.

• Helps regulate urine flow.

• Produces hormones.

What is endometriosis?

Endometriosis is a condition where tissue similar to the endometrium (uterine lining) grows outside the uterus.

Where does endometriosis commonly occur?

• Ovaries

• Fallopian tubes

• Pelvic region

How does endometriosis cause pain?

• The tissue outside the uterus breaks down like the normal uterine lining during menstruation.

• However, it cannot leave the body.

• This causes inflammation, scarring and pain.

What causes endometriosis?

The exact cause is unknown.

Ultrasound

• Uses sound waves to create images of reproductive organs.

• Can identify some abnormalities.

MRI scan

• Provides detailed images of the pelvis.

• Helps assess the extent of endometriosis.

Laparoscopy

• Keyhole surgery where a camera is inserted into the pelvic cavity.

• The only definitive method of diagnosis.

What is laparoscopic surgery for endometriosis?

• A keyhole surgery where a camera is inserted into the pelvic cavity.

• Endometrial tissue outside the uterus is removed using instruments, laser or heat.

What are the benefits of laparoscopic surgery?

• Small cuts are made in the abdomen.

• Recovery time is usually quicker.

• Diagnosis and treatment can happen during the same procedure.

What are the limitations of laparoscopic surgery?

What are the benefits and limitations of a hysterectomy for endometriosis?

Benefits:

• Removes affected reproductive organs.

• Can reduce symptoms in severe cases.

Limitations:

• The female cannot become pregnant after removal of the uterus.

• It is a major surgical procedure.

• Risks include bleeding, infection and damage to nearby organs.

How can pain relief help treat endometriosis?

• NSAIDs such as ibuprofen reduce inflammation and pain by blocking prostaglandin production.

• Paracetamol can also relieve pain.

How do hormonal medicines treat endometriosis?

• They reduce or prevent oestrogen production.

• This slows the growth of endometrial tissue.

• Contraceptives containing progestogens can reduce symptoms by acting like progesterone.

What are the limitations of non-surgical treatments for endometriosis?

• They do not improve fertility.

How does family history increase the likelihood of endometriosis?

Having a close relative, such as a mother or sister, with endometriosis increases risk.

How does starting periods at an early age increase the likelihood of endometriosis?

Early menstruation means the reproductive system experiences more menstrual cycles, increasing exposure to endometrial tissue changes.

How do short menstrual cycles increase the likelihood of endometriosis?

More frequent periods mean the endometrium is shed more often, increasing the chance of endometrial tissue developing abnormally.

How do heavy menstrual periods increase the likelihood of endometriosis?

Heavy periods involve greater shedding of the uterine lining, increasing the likelihood of endometrial tissue being present outside the uterus.

NSAIDs and other painkillers reduce inflammation and pain caused by endometrial tissue.

How do hormonal medicines and contraceptives help control endometriosis?

• Reduce oestrogen effects.

• Slow the growth of endometrial tissue.

• Reduce symptoms.

How can reducing stress help control endometriosis?

Reducing stress may help lower inflammation and improve symptoms.

How can dietary changes help control endometriosis?

• A healthy balanced diet helps maintain a healthy weight and provides nutrients.

• Foods containing vitamin D and magnesium may help with inflammation and muscle spasms.

• Reducing alcohol may help because alcohol can increase oestrogen levels.

How is testicular cancer diagnosed using physical examination?

• A healthcare professional examines the testes.

• They check for lumps, swelling or abnormalities.

How is ultrasound used to diagnose testicular cancer?

• An ultrasound scan of the scrotum is performed.

• It identifies whether a lump is benign (non-cancerous) or malignant (cancerous).

How are blood tests used to diagnose testicular cancer?

Blood tests check for tumour markers (hormones) that may indicate cancer.

How is a biopsy used in testicular cancer diagnosis?

A small sample of the lump can be examined to identify cancer cells.

How is testicular cancer monitored after treatment?

• Patients are monitored regularly for several years.

• This checks that the cancer has not returned.

What is an orchidectomy?

An orchidectomy is the surgical removal of the affected testicle.

Why is an orchidectomy performed for testicular cancer?
