  1. Male and Female Reproductive Systems

  2. Similarities / Differences • Develop very similar structures of sex glands • Both sexes have reproductive organs call GENITALS or GENITALIA, designed for the purpose of intercourse and conception. • Only the female has organs for pregnancy and childbirth.

  3. s e x u a l i t y a n d u . c a M a l e r ep r o d u c t i v e s y s t e m Seminal vesicles Vas deferens Prostate gland Penis Epididymis Testicle

  4. External Male Reproductive • 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).

  5. Internal Male Reproductive • Testosterone: the male reproductive hormone made by the testicles which causes the changes of puberty. • Sperm: the microscopic cells produced by the male’s testicles which can fertilize the female’s ovum. • Prostate Gland: This gland stores and secretes an alkaline fluid that neutralizes the acid found in the male urethra and the female reproductive tract so the sperm do not die • Cowper’s Glands: Two glands beneath the prostate gland that secrete a clear, sticky fluid that is alkaline to help lubricate and neutralize the acidity of the urethra (pre ejaculatory fluid) • Ejaculatory duct: a short straight tube that passes into the prostate gland and opens into the urethra.

  6. 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 (singular): two tubes leading from the epididymis to the seminal vesicles. • Seminal Vesicles: Two small glands that secrete a fluid that nourishes and enables the sperm to move (basically sperm food).

  7. 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.

  8. External Female Anatomy • Vulva: woman’s external genital area. • Pudendum: the area in the body where the sex organs are located. *Less preferred term • 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.

  10. s e x u a l i t y a n d u . c a F e m a l e r ep r o d u c t i v e s y s t e m Fallopian tube Ovary Uterus Bladder Clitoris Cervix Urethra Vagina Anus

  11. 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. Internal Organs

  12. 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.

  13. 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.

  14. 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.

  15. s e x u a l i t y a n d u . c a F e m a l e menstrual c y c l e

  16. Male Time Line: Infancy Erections begin Ages 11-14 Secondary sex characteristics appear Ages 13-16 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. Female Time Line: Ages 9-12 Secondary sex characteristics appear Ages 11-14 Menstrual cycle begins Late 20-30’s Peak sexual urges Ages 45-55 menopause (cycle stops, but sex urge continues) Timelines

  17. Family Planning: The use of contraceptives Why and How

  18. Why? • If pregnancies are not planned, couples who are more fertile will have a child every 14 months for 25 years. • That makes you the parent of 21 children!

  19. Other Reasons • Experts in child development recommend 3-4 years space between children. • Less than two years spacing is difficult for mothers who need time for their bodies to return to normal. • Two children under the age of two creates much stress on the family.

  20. Historical Contraception & Superstitions • Egypt as early as 1550 BC used a tampon soaked with honey and ground acacia tips. • Greeks took two legs from a spider and attaching them to the woman with deerskin. • Jump backwards seven times after intercourse. • Spit into a frogs mouth three times. • Tie willow seeds around your neck. • Drink water that has been used to wash the dead. • By 1700, sheep gut was used as condoms.
