Male + Female Reproductive System

1. Male + Female Reproductive System Celine Murton Jackie Paiz Emily Hernandez Period 4

2. Female Reproductive System • Two main parts: • Uterus • Ovaries • Vagina • Clitoris • Fallopian Tube • Cervix • Urethra • Hymen • Labia Majora + Minora

3. Female Reproductive System • Uterus (womb) • Home of the fetus • Divided into two parts: • Cervix • Corpus • Ovaries • Produce eggs and hormones • Small oval-shaped glands • Located on each side of the uterus

4. Female Reproductive System • Vagina • Known as the birth canal • Canal that joins the cervix to the outside of the body • Clitoris • Two Labia Majora meet • Small and sensitive protrusion (comparable to a man’s penis) • Covered by prepuce (fold of skin)

5. Female Reproductive System • Fallopian Tube • Known as oviducts • Narrow tubes that attach to the upper part of the uterus • Serves as a tunnel for the ova (egg cell) to travel from the ovaries to the uterus • Where conception occurs

6. Female Reproductive System • Cervix • Known as the neck of the uterus • Cylinder shaped • Lower, narrow portion of the uterus where it joins with the top of the vagina • Protrudes through the upper anterior vaginal wall • Urethra • Its opening is just below the clitoris

7. Female Reproductive System • Hymen • A thin fold of mucous membrane • Separates the lumen of the vagina from urethral sinus A non-torn hymen is a guarantee of virginity? False

8. Female Reproductive System • LibiaMajora • Means “large lips” • Protects the other external reproductive organs • Female version of the scrotum • Contains sweat and oil-secreting glands • After puberty, it is covered with hair • LibiaMinora • Means “small lips” • Lies inside the labia majora • Surrounds the openings to the vagina and urethra

9. Male Reproductive System • Penis • Semen • Scrotum • Testicles (testes) • Epididymis • Vas Deferens • Ejaculatory Ducts • Urethra • Seminal Vesicles • Prostate Glands • Bulbourethral glands

10. Male Reproductive System • Penis • Male reproductive organ • Three main parts • The root (attached to the wall of the abdomen) • The body (the shaft) • The glans (cone-shaped end of the penis) • Glans are covered with a loose layer of skin, called the foreskin • Removal of the foreskin is called circumcision

11. Male Reproductive System • Penis • Three internal chambers • Made up of special, sponge-like erectile tissue (tissue contains thousands of large spaces that fill with blood when the man is sexually aroused) • Skin of the penis is loose and elastic to accommodate changes in penis size during an erection

12. Male Reproductive System • Semen • Contains sperm (expelled during ejaculation through the end of the penis when the man reaches sexual climax [orgasm]) • Flow of urine is blocked when penis is erect, allowing only semen to be ejaculated • Scrotum • loose puck-like sac of skin that hangs behind the penis • Contains testicles and many blood and nerve endings • Protects and acts as a climate control system for the testes

13. Male Reproductive System • Testicles (testes) • Oval shaped organs, size of large olives that lie in the scrotum • Responsible for making testosterone and sperm • Epididymis • Long coiled tube that rests on the backside of each testicle • Transports and stores sperm cells that produce in the testes • Brings the sperm to maturity

14. Male Reproductive System • Vas Deferens • Tube that travels from the epididymis into the pelvic cavity, to just behind the bladder • Sperm is transported here to the urethra in preparation for ejaculation • Ejaculatory Ducts • Vas deferens and the seminal vesicles, fused • Ducts empty into the urethra

15. Male Reproductive System • Urethra • Carries urine to the outside of the body • Ejaculates semen • Seminal Vesicles • Sac-like pouch that is attached to the vas deferens near the base of the bladder • Prostate Glands • Walnut-sized structure that is located below the urinary bladder in the form of the rectum • contributes additional fluid to the ejaculate

16. Male Reproductive System • Bulbourethral glands • Located on the sides of the urethra, just below the prostate gland • Pea-sized structure, also called the Cowper’s gland • Produce a clear, slippery fluid that empties directly into the urethra • Fluid serves to lubricate the urethra and to neutralize any acidity that may be present due to residual drops of urine in the urethra.

17. M+F Reproductive Disease • Cervical Cancer • Cancer in the cervix • Develops on surface of the cervix • 3rd most common cancer in women • 100% treatable if found in time • Develops slowly (over years) • Pap Smear tests are done annually • Almost always caused by HPV

18. M+F Reproductive Disease • Testicular Cancer • Begins in the testicles • Curable if caught in time, but it can be a very lengthy process before total recovery • Different stages: • Stage I: cancer has not spread beyond the testicle • Stage II: cancer has spread to lymph nodes in the abdomen • Stage III: cancer has spread beyond the lymph nodes

19. M+F Reproductive Disease • Chlamydia • Most common STD in United States • 1 in 4 men show no symptoms • 30% of woman show symptoms • Curable with antibiotics

20. Female Reproductive Doctor • Obstetrics & Gynecologist • Two separate surgical-medical specialties • Deal with the female reproductive organ in the non-pregnant and pregnant state • These specialties are so alike, they are often combined to form a single medical specialty, called (ObGyn).

21. Male Reproductive Doctor • Andrologist • Physician-scientist concentrates for clinical or laboratory evaluations of the male fertility and medical and surgical management of all the aspects of the male reproductive health • Found in fertility treatment centers working with in vitro fertilization • Urologist • Deals with two different parts of the male: • Urinary tract • Male reproductive system • Specializes in male anatomy, diagnosis, treatment, and prevention of genitourinary disorders
