1 Chapter 7 Sexuality I

2 Objectives Identify structures of the female & male sexual anatomy
Explain the female and male reproductive cycle Understand how STI’s are transmitted, who’s at risk, and ways to decrease the risk of contraction List the 3 different types of STI’s Understand how STI’s can be asymptomatic, yet still have chronic effects Differentiate between the various STI’s Identify treatments for the various STI’s Understand the complications of STI’s

3 Female Anatomy Labia majora & minora: protect the vulva, urethral opening, and vagina Clitoris: consists of erectile tissue and results in swelling during sexual arousal Ovaries: eggs produced here Fallopian tube: extends from the ovaries to the uterus, fertilization occurs here Uterus: fetus develops here, two parts: fundus & cervix Cervix: connects the vagina & uterus

4 Male Anatomy Penis: root – attaches to the body, shaft, & glans penis - covered by foreskin Scrotum: holds the testicles Testes: sperm and hormone production Vas deferens: long tube through which sperm travel during ejaculation Seminal vesicles: secretes fluid, providing nourishment & enhancing sperm motility Prostate: secretes thin, milky fluid into the urethra, increasing sperm motility Cowper’s gland: secretes the lubricating fluid, sperm left in the urethra from a previous ejaculation will combine with the fluid to form the pre-ejaculate lubricant

5 Sexually Transmitted Infections
WHO’S AT RISK??? ANYONE WHO IS SEXUALLY ACTIVE CHECK YOUR RISK PROFILE AT UNSPEAKABLE.COM WHAT IS CONSIDERED SEXUAL ACTIVITY??? ONLY VAGINAL INTERCOURSE?

6 Sexually Transmitted Infections
HOW ARE THEY TRANSMITTED? vaginal, oral, or anal intercourse by simply touching an infected area THREE MAIN TYPES Bacterial Viral Parasitic

7 Asymptomatic STI’s Bacterial STI’s
As many as 20% of infected males and 80% of infected females are without symptoms Viral STI’s have even higher percentages

8 Bacterial STI’s Chlamydia Gonorrhea Syphilis

9 Chlamydia Most common bacterial STI in the U.S.
Many cases are asymptomatic If symptoms are present, they will occur 1-3 weeks after infection Complications Blindness Sterility Ectopic pregnancy Treatment: Tetracycline, Doxyceline, or Erythromycin

10 Symptoms of Chlamydia Male Symptoms Female Symptoms
thin whitish discharge itching & burning during urination pain/swelling of testes low grade fever Female Symptoms moderate vaginal discharge itching & burning urination abdominal pain bleeding b/w periods nausea, headaches, low grade fever

11 Chlamydia The Secret Epidemic: STIs on Campus slides can be used by anyone: health educators, clinicians, peer educators, and other students. There are over 40 slides in the set. The contents include general information about infections, risks, prevention, testing, and the most prevalent STIs.

12 Gonorrhea Many cases are asymptomatic
If symptoms are present, they will occur 3-5 days after infection Complications: sterility Treatment: Penicillin, Spectinomycin, Cefixime Tetracycline, or Ceftriaxone

13 Symptoms of Gonorrhea Male Symptoms Female Symptoms
foul smelling discharge from penis painful urination blood or puss in urine enlarged lymph nodes in groin area Female Symptoms similar discharge from vagina painful urination pelvic pain painful menstruation

14 Syphilis THREE STAGES: 1. Painless sore 10-90 days after infection
2. Flu like symptoms 3wks -3 months after primary stage. 3. Skin lesions, mental deterioration, blindness, & heart disease yrs after primary and secondary stages. Treatment: Antibiotics, usually penicillin Complications: Can be fatal

16 Genital Herpes Approximately 40 million people infected
Simplex I and Simplex II Many individuals are asymptomatic If symptoms are present, they will occur 2-20 days after infection

17 Genital Herpes cont… Initial symptoms
tingling or burning sensation in the genitals low back pain pain when urinating Flu-like symptoms Red bumps develop into painful blisters Treatment of symptoms: Acyclovir, Famcyclovir, Valacyclovir

18 Genital Herpes The Secret Epidemic: STIs on Campus slides can be used by anyone: health educators, clinicians, peer educators, and other students. There are over 40 slides in the set. The contents include general information about infections, risks, prevention, testing, and the most prevalent STIs.

19 Transmitted one of four ways:
HIV & AIDS Transmitted one of four ways: Vaginal, anal, oral intercourse Sharing a needle Blood products containing HIV Mother to child Bodily fluids containing virus: blood, semen, vaginal secretions, breast milk Primary Population at Risk: young adults in their teens & 20’s

20 AIDS Cases by Age

21 HIV/AIDS cont… May be asymptomatic for years
HIV may not progress to AIDS for over 10 years No known cure at this time Symptoms: Fatigue, dry cough, fever, night sweats, diarrhea, skin rashes, swollen lymph nodes, vaginal yeast infections, and/or unexplained weight loss Treatment: mixture of different drugs to boost the immune system

22 Human Papilloma Viruses
Most common viral STI in the U.S. 3 million new cases a year Majority of Cases are ASYMPTOMATIC > 70 strains of HPV Means of Contraction: skin to skin contact, oral, anal, & vaginal intercourse

23 Human Papilloma Viruses
The Secret Epidemic: STIs on Campus slides can be used by anyone: health educators, clinicians, peer educators, and other students. There are over 40 slides in the set. The contents include general information about infections, risks, prevention, testing, and the most prevalent STIs.

24 Human Papilloma Viruses
The Secret Epidemic: STIs on Campus slides can be used by anyone: health educators, clinicians, peer educators, and other students. There are over 40 slides in the set. The contents include general information about infections, risks, prevention, testing, and the most prevalent STIs.

25 HPV cont… Male symptoms: Female symptoms: No known cure at this time
Genital warts on foreskin or shaft of penis Female symptoms: Genital warts on vaginal opening, cervix, or inner walls of vaginal No known cure at this time Treatment of symptoms: Topical application or surgery to reduce size and spreading

26 Hepatitis B Transmitted through blood, semen, and vaginal secretions
Spread mainly through sexual contact 90% eliminate the virus through immunoglobulins Of the chronic carriers, 15-20% will die from cirrhosis or liver cancer Vaccination is available 50% of adults infected are asymptomatic

27 Symptoms of Hepatitis B
Prodrome phase: diminished appetite, weight loss, fatigue, headache, nausea, vomiting, muscle aches, cough, low grade fever, right-sided upper abdominal pain Icteric phase: urine darkens, stools becomes a clay color, liver becomes enlarged and tender, itching, yellow cast to the skin or eyes Recovery phase: may develop a chronic disease Treatment for chronic disease: Interferon

28 Parasitic STI’s Pubic Lice Scabies

29 Pubic Lice & Scabies (“crabs”) (“itch mites”)
Tiny insects that live on the skin Pubic Lice infect hairy parts of skin Some may have no symptoms, while others have severe itching Scabies result in an itchy rash on the skin Itching may get worse at night Rash on folds of skin between fingers, wrists, elbows, abdomen, & genitals

Clean all clothes, linens, & towels in HOT water Avoid close contact with others…….. You must tell anyone whom you have had close contact or shared your bed linens, clothes, or towels

31 How do we prevent STI’s? ABSTINENCE
BE MATURE & RESPONSIBLE: Mutually monogamous relationships with an uninfected individual - testing Limit number of partners & always use condoms Realize Condoms aren’t 100% effective in protecting you!! If infected, avoid sexual contact & visit your physician, local STI clinic or hospital for diagnosis / treatment

Symptoms of STI’s can develop slowly or be asymptomatic Regular & accurate evaluations are necessary Only way to have adequate knowledge of your history is to be tested You’ll never know unless you’re tested! Communicate with your partner

33 Methods of Testing STI’s
3 Categories Inspection Symptomatic genital warts, herpes, and pubic lice Blood or Urine tests Blood tests: Hepatitis B, Syphilis, & HIV Urine tests: Chlamydia & Gonorrhea Smears form vagina or urethra/Fluid collection Fluid collection: Chlamydia, Gonorrhea, & Herpes

34 Complications of STI’s
Infertility Complications during pregnancy Infections can be passed onto the newborn Some can be fatal AIDS, Hepatitis B, Syphilis

35 Summary STI’s are transmitted by skin to skin contact, touching an infected area, vaginal, oral, and anal intercourse 3 main types of STI’s: bacterial, viral, & parasitic Many STI’s are ASYMPTOMATIC Bacterial STI’s can be treated with antibiotics Viral STI’s are life long infections Parasitic STI’s can be treated with shampoos and creams STI prevention includes: abstinence, mutually monogamous relationship with an uninfected individual, limit number of partners, use condoms, STI testing, communicating with your partner
