Your Reproductive Health
The two main functions are to produce and store
SPERM: the male gametes, or reproductive cells
- and transfer them to the female's body during sexual intercourse.
Between the ages of 12-15, a male will reach maturity and hormones produced in the pituitary glad stimulate the production of
TESTOSTERONE: the male sex hormone.
This initiates physical changes that signal maturity: broadening of shoulders, development of muscles, facial and other body hair, deepening of the voice and production of sperm.
Testes (testicles): two small glands that secrete testosterone and produce sperm
Scrotum: an external skin sac which holds the testes.
Penis: a tube-shaped organ that extends from the trunk of the body just above the testes
-The penis is composed of spongy tissue that is filled with many blood vessels. When blood flow increases it causes an erection to occur. Erections are normal body functions and occur more easily and frequently during puberty, and can also occur for no reason!
At birth, male babies are born with foreskin, which is when the tip of the penis is covered with a thin loose skin. Parents can decide to remove it or leave it alone. Removal is known as
There is no right or wrong decision! Sometimes decisions are based on cultural or religious reasons.
Sperm cannot live in temperatures higher than the normal body temperature of
degrees. The scrotum helps regulate temperature by tightening or relaxing. Wearing tight pants is not a smart idea... but it doesn't mean your pants should be so big that they fall below your butt!!
How does it work?
External Reproductive Organs
Did you know?....
When Erections Occur....
Semen can be ejaculated from the body.
Semen is a thick fluid containing sperm and other secretions from the male reproductive system.
At the height of sexual arousal, a series of muscular contractions known as EJACULATION may occur.
When an ejaculation occurs and a female has ovulated and is fertile, FERTILIZATION may occur. This is when the sperm cell and a female egg cell unite.
HOW DOES FERTILIZATION OCCUR?
WHAT FLUID CONTAINS SPERM?
WHAT IS THE HIGHEST TEMPERATURE THAT SPERM CAN LIVE AT?
CHECK YOUR KNOWLEDGE!
Although sperm are produced in the testes, which are suspended OUTSIDE the body, they must travel through several structures inside the body before they are released.
Look at your handout as we label these structures!
Internal Reproductive Organs
WORDS TO USE
Inguinal Hernia- part of the intestine pushes through a tear in the abdominal wall. (Be careful lifting heavy objects!!)
Sterility- the inability to reproduce. Exposure to X-rays, toxic chemicals, hormonal imbalance, anabolic steroids and STDs can cause this.
Testicular Cancer- Occurs most often in males between ages of 14-40. Early detection can help defeat it through chemotherapy, radiation or surgery.
Prostate Problems and Prostate Cancer- Can become enlarged as a result of infection, tumor or age.
Problems can occur...
1. Standing in front of a mirror, look for swelling. Examine each testicle with both hands. Roll the testicle gently between the thumbs and forefingers.
2. Cancerous lumps are usually found on the side of the testicle but can appear on the front. Find the epididymis so that you won't mistake it for a lump.
3. Most lumps are not cancerous. If you do find a lump or experience pain or swelling, consult a health care professional.
CANCER CHECK YOURSELF!!
THE FEMALE Reproductive System
The female reproductive system has several funtions including producing female sex hormones and storing the
eggs, female gametes or ova
ovaries are the female sex glands that store the ova and produce female sex hormones
. They are located on each side of the
uterus, the hollow, muscular, pear-shaped organ that nourishes and protects a fertilized ovum until birth
A FEMALE AT BIRTH HAS MORE THAN
IMMATURE OVA STORED IN THEIR OVARIES!!
At puberty the pituitary gland produces hormones that cause these ova to mature.
Ovulation: the process of releasing a mature ovum into the fallopian tube each month.
A mature ovum is released from an ovary and moves into one of the two
Fallopian Tubes: a pair of tubes with fingerlike projections that draw in the ovum.
hairlike structures called
work to move the ovum with the help of muscular contractions in the fallopian tubes. (Females may experience slight discomfort during this time.)
Sperm from the male enter the female reproduction system through the
vagina: a muscular, elastic passageway that extends from the uterus to the outside of the body.
If sperm are present in the fallopian tubes, the sperm and ovum may unite. The fertilization of an egg by a sperm produces a cell called a zygote. The zygote will leave the FT's and enter the uterus (Thick and rich with blood to nourish the baby) where it will remain attached until birth!
MENSTRUATION: The shedding of the uterine lining.
After the female matures, the uterus prepares each month for possible pregnancy. If pregnancy does not occur, the thickened lining of the uterus, called the endometriumm breaks down blood, tissue and fluids.
The endometrium tissues pass through the
cervix, the opening to the uterus
, and into the vagina.
Females wear sanitary pads or tampons to absorb the blood flow.
FYI: You CAN go swimming if you wear a tampon!
Try to mark on your calendar when you get your period so you are prepared for the day! As a female matures, it usually becomes more predictable, but better to know when to expect it then to be without protection!!
If you dont get it and were engaging in unprotected sex...
Most females begin their first menstral cycle between the ages of 10-15. Endocrine hormones control the cycle, but poor nutrition, stress, excessive exercise, low body weight, and illness can influence it!
A female will have her menstral cycle until menopause, the end of preporuction years, which usually occurs between the ages of 45-55.

I hope your ready!
I cry a lot, always need a diaper change and YOU can't leave me alone!
What can go wrong?
Infertility and Other Disorders
Endometriosis- when uterine tissue grows in the ovaries, fallopian tubes, or the lining of the pelvic cavity.
Cervical, uterine and ovarian cancers- early sexual activity and STDs increase the risk of cervical cancer.
Ovarian Cysts- fluid filled sacs on the ovary. May disappear on their own or need to be surgically removed. (depends on size)
Vaginitis- discharge, odor, pain, itching, or burning. Candida (yeast infection) and bacterial vaginosis are two common forms.
STDs- gonorrhea and chlamydia can cause PID and infertility.
TAKE CARE OF YOU!
HAVE REGULAR MEDICAL EXAMS.
GIVE YOURSELF A BREAST EXAM!
Look at the handout as I go over how to check yourself for breast cancer.
You will be able to feel what a lump would feel like at the end of class using the fake breast!
What are those pains?
Menstrual Cramps- sometimes occur at the beginning of a menstrual period. Light exercise or applying a heating pad to the abdominal area may help relieve cramps. If they become severe, talk to your doctor.
Premenstrual Syndrome (PMS)- a disorder caused by hormonal changes. Symptoms include anxiety, irritability, bloating, weight gain, depression, mood swings, and fatigue. Regular physical activity and good nutrition may reduce severity of symptoms.
Toxic Shock Syndrome (TSS)- a rare but serious bacterial infection that affects the immune system and liver. I can be fatal! Reduce your risk by using tampons with the lowest absorbency needed and change them often. Symptoms include: fever, vomiting, diarrhea, rash, red eyes, dizziness, and muscle aches.
YOU ARE NOW HEALTH LITERATE ABOUT YOUR BODY AND THE OPPOSITE SEX!
