1. Male & Female Reproductive System

2. External Male Reproductive
Testosterone: the male reproductive hormone made by the testicles which causes the changes of puberty.
Penis: the organ of transfer of sperm to female.
Scrotum: pouch-like sac holding both testicles in a separate compartment that hang underneath the penis.
Testicles – Testes Gland: two glands in the male, located in the scrotum, which produce male hormones (testosterone).
Seminiferous tubules: where immature sperm develop and grow

3. Internal Male Organs
Sperm: the microscopic cells produced by the male’s testicles which can fertilize the female’s ovum.
Prostate Gland: a man’s gland that helps make semen.
Cowper’s Glands: behind the base of the penis which secretes fluid to make semen and neutralize acid during sexual excitement.
Ejaculatory duct: a short straight tube that passes into the prostate gland and opens into the urethra.

4. Swimming for your life
A sperm is a tiny package with a big responsibility – to fertilize the egg and create a human life. So that tiny package is loaded with “gear” for its important journey.
A few facts:
Daily sperm production by a healthy man:
10 million to 50 million
Contents of average ejaculation:
50 million sperm; 25 million moving; 20 million deformed
Maturation: 72 days
Average swimming speed of a sperm:
8 inches per hour
Survival time in a woman: 2 to 7 days

5. Urethra: a tube that connects with the vas deferentia to carry sperm cells out of the body.
Epididymis: the structure that forms a mass over the back and upper part of each testes.
Vas Deferens: two tubes leading from the
epididymis to the
seminal vesicles.
Seminal vesicles:

6. Other related concerns
Circumcision: A process that surgically removes the flap of skin that covers the glans of the penis.
Ejaculation: when semen carrying sperm spurts out of penis
Semen: the thick, sticky fluid which contains sperm ejaculated by the male from the penis during orgasm (climax).
Nocturnal Emissions: normal, involuntary ejaculation of semen and sperm while a male is asleep.
Impotence: the failure to get or maintain an erection
Vasectomy: surgical procedure for sterilization of the male.

7. External Female Anatomy
Vulva: woman’s external genital area.
Pudendum or Pubes: the area in the body where the sex organs are located.
Mons Pubis: a mound of fatty tissue which covers the pubic bone.
Labia Majora: (large lips) two folds of skin running from the mons pubis to below the vaginal opening
Labia Minora: two smaller folds of tissue which lie just within the labia majora.
Clitoris: a small, pea-shaped bump at the front of the labia that contains erectile tissue (counter
part to male penis.)
Urethra: below the clitoris, the opening to the bladder.

8. Internal Organs
Hymen: a narrow fold of tissue encircling the entrance to the vagina.
Vagina: passageway between the uterus and the outside of a woman’s body.
Cervix: Opening from the uterus to the vagina.
Uterus: place where the baby grows in a woman’s abdomen.
Oviducts (Fallopian Tubes): two tubular structures leading from the ovaries to the uterus
Ovaries: organs holding a woman’s eggs.

11. Other related concerns
D&C: dilation and curettage, a common minor operation on women.
Endometriosis: fragments of the endometrium in abnormal places.
Orgasm: characterized by the massive release of muscle tension which has built up during excitement.
Dysmenorrhea: painful mentruation
Hysterectomy: surgical removal of uterus.

12. Tubal Ligation: an operation for sterilization of women.
PMS: premenstrual syndrome.
Menstrual Cycle: the process of passing the blood and tissue lining of the uterus from the body.
Toxic Shock Syndrome: caused by bacteria that live in the vagina, which then multiply and causes infection.
Menopause: the remaining ova no longer ripen or develop.

13. Estrogen: the hormone responsible for secondary sex characteristics and for the sex drive in females. The “egg producing” hormone.
Progesterone: builds up the lining of the uterus to prepare it for the fertilized ovum.; the “egg-setting” hormone.
Ovulation: time when the egg is released from the ovary.

14. Fertilization (conception): a sperm entering an ovum.
Follicle-stimulating Hormone (FHS): a substance which brings to life a few of the ovum in one of the ovaries.
Luteinizing Hormone (LH): causes the follicle to burst, and allows ovum to fall into the opening of the fallopian tube.
Ova –plural, Ovum—singular: the female reproductive cell.
Ovaries: organs holding a woman’s eggs.

17. Male Reproductive System
__f__ 1. cowper’s gland a. produce testosterone and sperm
__e__2. ejaculatory duct b. produces a milky fluid for sperm; when enlarged, can make
urination frequent/painful. Site of cancer.
__j__ 3. seminiferous tubules c. tube that transports urine or semen
__g__ 4. scrotum d. holds mature sperm
__i__ 5. glans e. contracts for semen to be expelled; blocks urination
during ejaculation
__c__ 6. urethra
f. two glands on either side of the urethra; add alkaline lubricating
fluid to sperm
__l__ 7. seminal vesicles g. regulates temperature for efficient sperm production
__a__ 8. teste h. transports sperm to the glands for semen production
__b__ 9. prostate gland i. organ most sensitive to sexual stimulation
__d__ 10. epididymis j. where immature sperm begin to develop
__h__ 11. vas deferens k. organ of sexual intercourse; its blood vessels engorge with blood
resulting in an erection
__k__ 12. penis l. glands that connect with the ejaculatory ducts; adds fructose for
nourishment for sperm

19. Female Reproductive System
1.__d___fimbrae a. The egg matures and is stored in these two organs.
2.__a___ovaries b. Membrane partly covering the opening to the vagina.
3.__k___vagina c. Set of lip-like folds that are the larger, outer folds.
4.__b___hymen d. Contain cilia that draw egg into “tube”
5.__h___labia minora e. Sensitive structure which becomes stimulated during sexual
intercourse.
6.__i___urethra f. Carries eggs/ovum from ovaries to uterus.
7.__e___clitoris g. Muscular organ where the fertilized egg grows.
8.__j___cervix h. Set of lip-like folds that are smaller and inner.
9.__g___uterus i. Urine exits through this.
10.__f___fallopian tubes j. Opening to uterus. Dilates during labor. Site of potential cancer.
11.__c___labia majora k. Muscular passageway from uterus to outside the body. Organ
for sexual intercourse; passageway for menstrual fluid; birth canal.

20. Similarities between male and female reproductive systems
Develop very similar structures of sex glands (ovaries and testes)
Two genital tubes (fallopian tubes and vas deferens)
Manufacture the hormones of the other sex.
Both sexes have reproductive organs call GENITALS or GENITALIA, designed for the purpose of intercourse and conception.

21. Timelines Female Time Line: Male Time Line: Infancy Erections begin
Ages 9-12 Secondary sex characteristics appear
Ages Menstrual cycle begins
Late 20-30’s Peak sexual urges
Ages menopause (cycle stops, but sex urge continues)
Male Time Line:
Infancy Erections begin
Ages Secondary sex characteristics appear
Ages Sperm produced in adult amounts (puberty)
Late teens Peak sexual urges for boys
Throughout life If good health is present, there is the sex urge and ability to father children.
