1. Human Reproduction

2. Human Reproduction Both sexes have
gonads (organs that produce gametes)
Ducts to store and deliver gametes
Structures to facilitate copulation

3. Female Reproductive Anatomy

4. Ovaries – site of gamete production
Follicles – each consists of a single developing egg cell surrounded by tissue to nourish it
Ovulation – egg cell is ejected from the follicle
Corpus luteum – remaining follicular tissue after ovulation
Oviduct – (fallopian tube) where cilia sweep the egg toward the uterus – fertilization may take place here – where an ectopic pregnancy occurs

5. Female Reproductive Anatomy

6. Uterus – actual site of pregnancy – grows to accommodate the developing fetus
Endometrium – blood-rich layer of tissue that lines the uterus – where an embryo would implant and develop in normal pregnancy
Embryo – from zygote to about 9 weeks
Fetus – from 9 weeks to birth

7. Female Reproductive Anatomy

8. Cervix – narrow neck at the bottom of the uterus
Vagina – birth canal – where sperm are deposited
Vulva – outer structures of the female anatomy
Urethra – tube through which urine is excreted
Labia minora – skin folds that border the opening to vagina
Labia majora – fatty skin folds that protect the genital region
Hymen – thin membrane that partially covers the vaginal opening
Clitoris – short shaft supporting a rounded glans – very sensitive due to numerous nerve endings

9. Male Reproductive Anatomy

10. Penis – (contains erectile tissue that can fill with blood and cause an erection during sexual arousal) – shaft that supports a glans – (very sensitive due to numerous nerve endings)
Testes – male gonads located outside the body in the scrotum
Scrotum – sac that holds testes away from the body (lower temperature) for proper development and function of sperm.
Epididymis – store sperm while they finish development
Ejaculation – expulsion of sperm containing fluid from the penis.

11. Male Reproductive Anatomy

12. Pathway of sperm during Ejaculation
Leave epididymis
Vas deferens – duct
Seminal vesicles and prostate gland add nourishing fluid to sperm and provides protection from acidic vagina
Empties into urethra (carries both semen and urine out of the penis)
Semen – about 5 mL, 95% fluid from glands and 5% sperm cells
