MythCancers of the male reproductive system only affect older men.

Fact Cancer of the testes (testicular cancer) most often occurs in teens and young men.


Structure and function

Structure and Function

  • In males, the reproductive cells are called sperm.

  • The functions of the male reproductive system are

  • to produce sex hormones

  • to produce and store sperm

  • to deliver sperm to the female reproductive system

  • There, a sperm cell may join with an egg, in a process called fertilization.


Testes

Testes

  • The testes (TES teez) are the male reproductive glands.

  • The testes (singular, testis) have two major functions—the production of testosterone and the production of sperm.

  • The sex hormone testosterone affects the production of sperm and signals certain physical changes at puberty.

  • The testes, also called testicles, hang outside the body within a sac of skin called the scrotum.

Penis

  • The penis is the external sexual organ through which sperm leave the body.

  • The tip of the penis (glans) is covered with loose skin, called the foreskin.

  • In some males the foreskin is removed shortly after birth in a procedure called a circumcision.

  • The body of the penis is cylindrical in shape and consists of three circular shaped chambers. These chambers fill with blood when the man is sexually aroused.


Other structures

Other Structures

Epididymis: Long, coiled tube that rests on the backside of each testicle. It transports and stores sperm cells that are produced in the testes.

Vas Deferens: Long, muscular tube that travels from the epididymis into the pelvic cavity, to just behind the bladder. They transport mature sperm to the urethra.

Ejaculatory Ducts: These are formed by the fusion of the vas deferens and the seminal vesicles. These ducts empty into the urethra.

Other structures1

Other Structures

Urethra: The tube that carries urine from the bladder to outside the body. When the penis is erect during sex, the flow of urine is blocked from the urethra, allowing only semen to be ejaculated at orgasm.

Seminal Vesicles: Sac-like pouches that attach to the vas deferens near the base of the bladder. They produce sugar-rich fluid that provides sperm with a source of energy to help them move. This fluid makes up most of the volume of a man’s ejaculatory fluid.

Other Structures

Prostate Gland: A walnut sized structure that is located below the urinary bladder in front of the rectum. It contributes additional fluid to the ejaculate to help nourish the sperm.

Bulbourethral Glands: Also called Cowper’s glands, pea-sized structures located on the sides of the urethra just below the prostate. They produce a clear, slippery fluid that empties directly into the urethra to lubricate and neutralize any acidity due to residual drops of urine in the urethra.

Sperm production

Sperm Production

  • Sperm production begins when the hypothalamus signals the pituitary gland to release two hormones—luteinizing hormone (LH) and follicle-stimulating hormone (FSH).

  • LH signals the testes to begin making testosterone.

  • Testosterone and FSH then signal the production of sperm.

The pathway of sperm

The Pathway of Sperm

  • During their passage through the male reproductive system, sperm cells mix with fluids produced by the prostate and two other glands.

  • The mixture of sperm cells and these fluids is called semen(SEE mun).


How could you give someone 63 using six bills without using one dollar bills

Sperm travel through the vas deferens to the seminal vesicles.

Seminal vesicles add a fluid that provides a source of energy for the active sperm.

The prostate gland adds a fluid that protects the sperm.

The bulbourethral glands add a lubricating fluid that aids the passage of sperm through the urethra.

The Pathway of Sperm

Sperm are produced in the testes. They mature and are stored in the epididymis.

Release of sperm

Release of Sperm

  • The ejection of semen from the penis is called ejaculation.

  • Ejaculation occurs when muscles in the male reproductive system and at the base of the bladder contract, forcing semen through the urethra.

  • Several million sperm cells are released during one ejaculation.

  • Ejaculation can occur when the penis is in an erect state.


Keeping healthy

Keeping Healthy

Caring for the male reproductive system involves

  • cleanliness

  • sexual abstinence

  • protection from trauma

  • self-exams

  • regular medical checkups

    • Hernia: A hernia occurs when an organ or fatty tissue squeezes through a hole or a weak spot in a surrounding muscle or connective tissue called fascia.

      • CAUSE: Anything that causes an increase in pressure in the abdomen can then cause a hernia, including obesity, lifting heavy objects, diarrhea or constipation, or persistent coughing or sneezing.

Structure and function1

Structure and Function

  • The reproductive cells in females are called eggs or ova (singular, ovum).

  • The functions of the female reproductive system are

  • to produce sex hormones

  • to produce eggs

  • to provide a nourishing environment in which a fertilized egg can develop into a baby

The menstrual cycle

The Menstrual Cycle

  • Women usually produce only one mature egg cell each month during a process called the menstrual cycle (MEN strooul).

  • During the menstrual cycle, an ovary releases a mature egg.

  • The egg travels to the uterus.

  • If the egg is not fertilized, the uterine lining is shed and a new cycle begins.


Factors affecting the menstrual cycle

Factors Affecting the Menstrual Cycle

  • On average, a woman’s menstrual cycle lasts 28 days.

  • Factors such as diet, stress, exercise, and weight gain or loss also affect the menstrual cycle.

  • The menstrual cycle may be irregular at times, especially during puberty.

  • During menopause, the ovaries slow down their hormone production and no longer release mature eggs.


How could you give someone 63 using six bills without using one dollar bills

Days 1–4 The uterine lining is shed during menstruation.

Days 5–13 An egg matures in one of the ovaries, and the uterine lining starts to thicken.

Days 14–15 The ovary releases the mature egg during ovulation.

Maturing Egg

Days 16–22 The egg travels through the fallopian tube to the uterus, and the uterine lining continues to thicken.

Egg

Days 23–28 The unfertilized egg enters the uterus.

The Menstrual Cycle


Stages of the menstrual cycle

Stages of the Menstrual Cycle

  • During the first half of the cycle, an egg matures inside one of the ovaries.

  • At about the middle of the cycle ovulation occurs.

  • If the egg has not been fertilized by the time it reaches the uterus, the uterine lining breaks down.

  • The blood and tissue of the thickened lining pass out of the body through the vagina in a process called menstruation.

YouTube: The Menstrual Cycle


Menstrual discomfort

Menstrual Discomfort

  • Cramps are caused by contractions of the uterus.

  • Premenstrual syndrome, or PMS, is marked by nervous tension, mood swings, headaches, bloating, and irritability.

  • The dramatic change in hormone levels that occurs before menstruation begins may cause PMS.


Toxic shock syndrome

Toxic Shock Syndrome

  • This syndrome is caused by a bacterial infection.

  • Symptoms of toxic shock syndrome include

  • a sudden high fever

  • a rash

  • vomiting

  • diarrhea

  • dizziness

  • To decrease the risk of toxic shock syndrome, women should use tampons with the lowest possible absorbency for their needs and change tampons often.


Keeping healthy1

Keeping Healthy

Caring for the female reproductive system involves

  • cleanliness

  • sexual abstinence

  • prompt treatment for infections

  • self-exams

  • regular medical checkups


Cleanliness

Cleanliness

  • One important health habit is cleanliness, including daily washing of the external vaginal area.

  • Cleanliness is especially important during menstruation, as is the regular changing of sanitary pads or tampons.


Sexual abstinence

Sexual Abstinence

  • A number of serious infections can result from sexual contact.

  • The only way to eliminate your risk of sexually transmitted infections is to abstain from sexual activity.


Prompt treatment for infections

Prompt Treatment for Infections

  • Many women experience vaginitis, a vaginal infection caused by yeast, bacteria, or other microorganisms.

  • Symptoms include

  • a thick discharge

  • odors

  • vaginal itching

  • a burning sensation during urination


Self exams

Self-Exams

  • Symptoms of vaginitis, sores on the genitals, or any unusual pain in the abdomen require a medical exam.

  • A woman should consult a doctor

  • if she notices heavier bleeding than normal during menstruation

  • if her periods stop completely

  • if she notices bleeding at times between her regular periods

  • For the early detection of breast cancer, all women, including teens, should perform a monthly breast self-examination.


Medical checkups

Medical Checkups

  • In a Pap smear, a sample of cells is taken from the cervix and examined under a microscope.

  • A mammogram is an X-ray of the breast that can help detect breast cancer.

  • Ovarian cysts Ovarian cysts are growths on the ovary.

  • Endometriosis This is a condition in which tissue from the lining of the uterus—the endometrium—grows outside the uterus, in the pelvic cavity.

  • Infertility Causes of infertility in women include blocked fallopian tubes and problems with ovulation.
