Pressure….? No one can make you feel inferior without your consent. Eleanor Roosevelt, 'This Is My Story,' 1937

The 21st Century Version of the Birds & Bees... A little boy goes to his father and asks "Daddy, how was I born?" The father answers, "Well, son, I guess one day you will need to find out anyway.  Your mom and I first got together in a Chat room on Yahoo.  Then I set up a date via Email with your mom, and we met at a Cyber-Cafe.  We sneaked into a secluded room, where your mother agreed to a Download from my Hard Drive. As soon as I was ready to Upload, we discovered that neither of us had used a Firewall, and since it was too late to hit the Delete button, nine months later a blessed little Pop-Up appeared and said: You've Got Male."

Male & Female Reproductive System

The Least You Need to Know: Identify the basic components of the male and female human reproductive systems. Describe the basic functions of the various components of the male and female reproductive systems. Describe the basic stages of the menstrual cycle and distinguish among ovulation and conception.

Similarities / Differences Develop very similar structures of sex glands Two genital tubes Manufacture the hormones of the other sex. Hormones of one sex are often used to treat illness in the other sex. 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.

Male Reproductive System 1 A. Two functions: 1. produce sperm cells 2. deposit sperm cells in female reproductive tract the testicles (produce sperm/testosterone) the duct system, which is made up of the epididymis, the vas deferens, and the urethra (passageways) the accessory glands, which include the seminal vesicles, prostate gland, and cowper’s gland Nutrients Mobility Protection the penis (delivery)

Male Reproductive System 2

Male Organs Scrotum: Temperature Regulation/ House the Testicles Testicles: sperm and testosterone production Sperm: the sex cells produced by the male’s testicles which can fertilize the female’s ovum. Epididymus: Where sperm mature Vas Deferens: Passageway from epid to seminal vesicles Seminal Vesicles: stores mature sperm and contribute fluid towards ejaculation (semen) Prostate Gland: contributes most of the fluid in semen. Cowper’s Glands: secretes fluid to make semen and neutralize acid during sexual excitement. Urethra: where urine and semen leave the penis. Penis: male reproductive organ Male Organs

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: 120-600 million sperm; (millions deformed) Maturation: 64-72 days Average swimming speed of a sperm: 8 inches per hour Survival time in a woman: 2 to 7 days

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 leaves the penis Semen: the combination of fluid from the accessory glands and sperm and 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.

Internal Female Reproductive Organs Vagina: passageway between the uterus and the outside of a woman’s body. Cervix: Opening from the uterus to the vagina. Uterine Lining: Endometrium-The thick tissue inside the entire uterus Uterus: place where fetal development takes place. Fallopian Tubes: two tubular structures leading from the ovaries to the uterus Fimbria: fingerlike structures at the end of each fallopian tube Ovaries: organs holding a woman’s eggs.

External Female Anatomy Labia Majora: 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.

Key Terms to Understanding the Menstrual Cycle Ovulation: time when the egg is released from the ovary. Usually, conception joining of the sperm and egg occurs in the fallopian tube. If fertilization does not occur, this lining is shed every month. This is called menstruation, the process by which the uterus rids itself of its old lining, and prepares for the possibility of conception the following month. About 14 days after ovulation, the body begins to shed the uterine lining, which is made up of blood and fluid. This is commonly called a “period”.

Four Stages of the Menstrual Cycle: a. follicle stage -FSH from the pituitary gland stimulates the a follicle to begin maturing an ovum. The developing follicle produces estrogen--begins vascularization of the uterine wall (10-14 days) b. ovulation-release of ovum from follicle c. corpus luteum stage-initiated by LH from the pituitary-- follicle develops into a “yellow body” and produces progesterone--readies the female for becoming pregnant d. menstruation-shedding of the thickened uterine lining if fertilization does not occur

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.

Possible Times of Fertility The female undergoes a regular, complex cycle approximately every 28 days in order to produce a mature ovum--called the menstrual cycle

The Menstrual Cycle

Other related concerns Endometriosis: fragments of the endometrium in abnormal places. Hymen: a narrow fold of tissue encircling the entrance to the vagina. Dysmenorrhea: painful menstruation Hysterectomy: surgical removal of uterus. 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. Tubal Ligation: an operation for sterilization of women. PMS: premenstrual syndrome.
