Stages of Life

The Male Reproductive System

• The male body– Prostate gland- a gland in the male reproductive

system that makes fluid that helps carry sperm.– Sperm- the male sex cell– Testes(testicles)- the organs the make the sperm

and the primary male sex hormone, Testosterone– Scrotum- sac of skin that hold the testes.– Epididymis- where sperm mature– Penis- Exit point for the body

The Path Traveled by Sperm• Seminiferous Tubules- structures where cells are made, located in

the testes– Genes- instructions for how a person’s body looks and functions

• They then move to epididymis where they mature• Once mature the sperm moves into tubes called Vas Deferens• The sperm then passes through the Seminal Vesicles, which

provide the sperm with fluid to help it on it’s journey, Semen• The sperm then passes through the prostate gland, and the

Cowper’s gland, where it recieves more fluid.• The sperm then enters the Urethra, which runs through the penis

and out the body.• After two weeks in the body the sperm is reabsorbed by the body

The Male Reproductive System• Male reproductive problems

– Check yourself regularly– Be aware of Noticeable Symptoms:

• Uncomfortable rash• A sore or lump• Painful urination• Some problems do not have symptoms

• Caring for the male body– Bath every day– -wear protective gear for sports– -regular checkups– -abstain from sex

The Female Reproductive System• The female body

– Uterus- a muscular organ of the female reproductive system that holds a fetus during pregnancy

– Endometrium- the lining of the uterus– Ovum- women’s sex cell– Ovaries- where eggs, or ova, are made and stored

• Female sex hormone also produced here, Estrogen

– Fallopian Tube- pathway for egg to travel– Cervix-lower part of the uterus, where the uterus meets the

vagina– Vagina- connects the outside of the body with the uterus– Breast- also a part of the female reproductive system

Ovulation/Menstruation

• Ovulation- beginning at puberty, one of the ovaries releases a mature egg every month.– Eggs contain one half of the woman’s genes– One egg will be most dominate, other will be

reabsorbed by the body• Menstruation- the monthly breakdown and

shedding of the endometrium, a.k.a. a period

Path of an Egg

• The egg or ova forms in the ovaries(day1-13)• The egg is then released from the Ovary(Ovulation,

day14)• The fallopian tube then draws the egg in, along with

other fluids, and sends it towards the uterus(15-28)• If the egg is fertilzed a pregnancy begins• If the egg is unfertilized Menstruation continues(days

1-5)• Full cycle takes 28 days and is known as the

menstrual cycle.

The Female Reproductive System• Common Reproductive Problems

– Many problems related to the Menstrual Cycle– Irregular periods– Heavy flow, or light flow normal– Cramps are normal– Page 224

• Caring for the Female Body– Bathe everyday– Regular checkups– Abstain from sex– Good hygiene during periods
