Genital Warts (HPV)
Photo of Genital Warts.

It's not necessary to have sexual intercourse to get a sexually-transmitted disease (STD). The human papillomavirus (HPV) that causes genital warts can be transmitted by close skin-to-skin contact. Some types of HPVs cause cervical or anal cancer, and vaccines are available to protect against the most dangerous types. Other HPV types cause genital warts, which can be raised, flat, or cauliflower-shaped. HPV infection can occur in people who have no symptoms or visible warts.

HPV Symptoms

Genital warts can be big or small, flat or raised. They generally appear as a small bump or group of bumps in the genital region, and may be shaped like a cauliflower.

HPV Vaccine

A vaccine to prevent HPV is given in three shots. The second shot is given a month or two after the first shot. The third shot comes six months after the first shot.
The Centers for Disease Control recommends boys and girls be vaccinated at ages 11 or 12.
If they did not get the HPV vaccine as children, women can get the HPV vaccine through age 26. Men can get it through age 21. The CDC recommends HPV vaccination for men through age 26 for men who have sex with men or men with compromised immune systems, including HIV.

Pubic Lice (Crabs STD)
Photo of Pubic Lice.

Pubic lice are colloquially known as "crabs." This name refers to the shape of these parasites, which is different from that of body lice. Pubic lice live in pubic hair and are spread among people during close contact. Pubic lice can be treated with over-the-counter lice-killing medications.

Pubic Lice (Crabs) Symptoms

Severe itching
Visible crawling lice or eggs attached to pubic hair 

Scabies

Scabies is another disease caused by lice infestation. It is not necessarily an STD, since it can affect any area of the skin. However, it is often spread during sexual contact.

Scabies Symptoms

Extreme itching that is worse at night.
The skin appears to have a pimple-like rash, as shown in this photo.
Both the itching and rash may be across the body or limited to the wrist, elbow, armpit, webbing between fingers, nipple, penis, waist, belt-line or buttocks.
Tiny blisters (vesicles) and scales may appear.
Tiny burrows left by the tunneling of female scabies mites may be visible on the skin.
They appear as tiny raised and crooked grayish-white or skin-colored lines.

Prescription creams can cure a scabies infestation.
Gonorrhea (The Clap)

Gonorrhea is an easily transmissible STD that affects both men and women. It can cause infertility in men and women when untreated. There may be no early symptoms of the infection.

Gonorrhea Symptoms

Burning during urination
Vaginal or urethral discharge
Pelvic pain in women
Men may experience swelling of the testes and discharge from the penis

In some cases, the symptoms are mild and the condition is mistaken for a urinary tract infection or yeast infection.
Syphilis
Photo of Syphilis infections.

Syphilis can be cured with antibiotics, but many people don't notice the early symptoms. It can lead to nerve damage, blindness, paralysis, and even death overtime if not treated.

Syphilis Symptoms

A round, firm, painless sore on the genitals or anal area (often the first sign)
A rash can develop later on the soles of the feet, palms, or other parts of the body
Enlarged lymph nodes
Fatigue
Hair loss
Late-stage syphilis can cause damage to many different organ systems

Chlamydia

Chlamydia is a very common infection transmitted by sexual contact. It can cause infertility if not treated. The symptoms may not be noticed, or they may be vague and nonspecific. Some people have no symptoms at all.

Chlamydia Symptoms

Burning or itching of the genitals
Discharge
Painful urination

Chlamydia infections can also develop in the rectum and throat.
Herpes Simplex 1 Virus (Oral Herpes)
Photo of Herpes Simplex Virus Type 1 (oral herpes).

Cold sores or "fever blisters" on the lips are a sign of herpes virus infection, usually caused by the type of herpes virus known as human herpes virus 1, or HHV-1. HHV-1 is usually not considered to be an STD; however, it can be spread through kissing or household contact. It can also spread to the genitals. There is no cure for herpes infection, but medications can reduce the severity and duration of outbreaks.

Herpes Simplex 1 (Oral Herpes) Symptoms

Itching of the lips or skin around the mouth
Burning near the lips or mouth area
Tingling near the lips or mouth area
Sore throat
Swollen glands
Painful swallowing
A rash may form on your gums, lips, mouth or throat

Symptoms usually appear 1-3 weeks after first infection. When symptoms return, they are typically milder.
Herpes Simplex 2 Virus (Genital Herpes)
Photo of Herpes Simplex Virus Type 2 (genital herpes)

In contrast to HHV-1, most genital herpes infections are caused by a different virus known as HHV-2. It is spread through direct contact and is considered to be an STD. More than 87 percent of those infected with genital herpes are unaware of their infection due to very mild or nonexistent symptoms.

Herpes Simplex 2 (Genital Herpes) Symptoms

Painful, fluid-filled blisters and crusted sores on the genital area, buttocks, thighs, or anus.
Mild tingling or shooting pain in the legs, hips, or buttocks may occur hours to days before a genital herpes outbreak.
After the first infection, less severe outbreaks are common in the first year. Outbreaks tend to decrease over time, though the infection may stay in the body indefinitely.

The infection can spread to the lips through oral contact. As with HHV-1, medications can reduce the severity of the condition, but there is no cure.
Hepatitis B
Photo of Hepatitis B Virus.

Hepatitis B is a virus that spreads through contact with body fluids and blood, so it can be transmitted through sexual intercourse. Hepatitis B infection is also possible through sharing of needles, razors, and toothbrushes. Babies can become infected at birth from an infected mother. It's possible to go for years without symptoms of the infection.

Hepatitis B Symptoms

Nausea
Abdominal pain
Jaundice (yellowing of the skin and whites of the eyes)
Over time, scarring of the liver (cirrhosis) and liver cancer can develop

Although there is no cure, there is a vaccine to prevent hepatitis B infection.
HIV/AIDS
Photo of HIV infections.

The HIV virus (AIDS virus) weakens the body's immune system. It is spread through sexual contact, needle sharing, or from an infected mother to baby. There may be no symptoms for years, but a blood test can tell if you have been infected. With appropriate treatment, many serious illnesses can be prevented.

HIV Symptoms

Flu-like symptoms 1 to 2 months after first infection, including like swollen lymph nodes, fever, and headaches
Chills
Rash
Night sweats
Muscle Aches
Sore throat
Swollen lymph nodes
Mouth ulcers

AIDS Symptoms

Rapid weight loss
Recurring fever or profuse night sweats
Extreme and unexplained tiredness
Prolonged swelling of the lymph glands in the armpits, groin, or neck
Diarrhea that lasts for more than a week
Sores of the mouth, anus, or genitals
Pneumonia
Red, brown, pink, or purplish blotches on or under the skin or inside the mouth, nose, or eyelids
Memory loss, depression, and other neurologic disorders

HIV Testing

There are accurate tests to identify whether or not you have been infected with the HIV virus. These can be done in the clinic or at home with the FDA-approved Home Access test kit. The test can be performed anonymously, with only a number to identify you. However, sometimes people may not test positive in the initial 6 months after infection. This time period is referred to as the "window period" in which antibodies may not have developed enough for a positive test. You can still transmit the virus to others during this time.
HIV/AIDS Treatment Options

While there is no cure for HIV, there are medications that can suppress the amount of virus multiplying inside the body. People take a combination of antiviral drugs in hopes of preventing the infection from advancing to AIDS. Additional treatments can help prevent or fight off serious infections, if the immune system has weakened.
Trichomoniasis
Photo of Trichomoniasis parasite.

Trichomoniasis is a parasitic infection (caused by Trichomonas vaginalis) that is spread during sexual contact. It affects both men and women and can be cured with medications. Most affected men have no specific symptoms.

Trichomoniasis Symptoms

Men: minor discharge or burning with urination
Women: yellowish-green vaginal discharge with a prominent odor, itching of the vaginal area, or painful sex or urination 

Symptoms can develop anywhere from 5 to 28 days after contracting the infection.
Chancroid
Photo of Chancroid infections.

Chancroid is an STD that is rarely seen in the U.S. It is more common in Africa and Asia. It causes painful lumps in the genital area that can progress to open sores. Antibiotics can cure the infection; chancroid is caused by bacterial infection with Haemophilus ducreyi.

Chancroid Symptoms

One or more sores or raised bumps on the genitals. A narrow, red border surrounds the sores. The sores become filled with pus and eventually rupture into a painful open sore.
About half the time when untreated, the chancroid bacterial infection spreads to the groin's lymph glands, causing the groin to enlarge and become hard and painful.

Lymphogranuloma venereum (LGV)
Photo of Lymphogranuloma venereum (LGV) infection.

Lymphogranuloma venereum (LGV) is a type of chlamydial infection, but it is caused by a different type of chlamydia (Chlamydia trachomatis) than the usual chlamydial STD. Like other chlamydial infections, it can be cured by antibiotic treatment.

Early Lymphogranuloma venereum Symptoms (3-12 Days After Exposure)

Soft red, painless sores on or near the genitals or anus
Similar sores in the throat or mouth following oral sex

Later Lymphogranuloma venereum Symptoms (2-6 Weeks After Exposure)

Open sores in the genitals
Swollen lymph nodes in the groin
Headache
Anal sores and rectal discharge or bleeding if the infection was acquired through anal sex
Painful urination
Constipation
Rectal bleeding
Pain in lower back/abdomen
Pus-filled or bloody diarrhea
Fever, chills, joint pain, decreased appetite and fatigue

Pelvic Inflammatory Disease
Photo of Pelvic Inflammatory Disease.

Pelvic inflammatory disease (PID) is not a specific STD. Rather, it is a complication that can develop following multiple different STDs, particularly gonorrhea and chlamydia. In PID, bacteria spread to the uterus and female reproductive tract. Infertility may result if the condition is not treated right away.

Pelvic Inflammatory Disease Symptoms

Fever
Pelvic or low abdominal pain
Painful urination
Discharge
Painful intercourse
Light bleeding

Who's at Risk for STDs?

It's estimated that half of sexually active young adults acquire an STD by age 25. In fact, STDs are the most common type of infection in America. While STDs are more common in teens and young adults, anyone who is sexually active is at risk. The risk is raised by having multiple sex partners. The incidence of some STDs, including LGV and syphilis, is rising in men who have sex with men.
Can Virgins Get STDs?

Many STDs can spread through any type of sexual activity. This includes skin-to-skin contact and oral sex. This means that people who have not yet had sexual intercourse can still get STDs.
STD Prevention
Photo of gloved hands.

Abstinence from any sexual contact is the only absolute way to prevent getting an STD. Being in a long-term, monogamous relationship also is a good way to avoid STDs. There are also steps you can take to decrease the chance of getting an STD if you are sexually active, including:

Asking partners if they have ever had an STD
Using condoms
Avoiding sexual activity with a partner who has signs of an STD
Asking partners to be tested before having sex
Being aware of symptoms and signs of STDs

The Limits of Condoms
Photo of condom.

Condoms can prevent the spread of some STDs, but they aren't 100% effective. They are less effective at protecting against herpes, syphilis, and genital warts, since these STDs can be transmitted by contact with skin lesions that are not covered by a condom. Condoms also do not protect against crabs and scabies infestations.
How to Tell Your Partner You Have an STD
Photo of couple talking about STDs.

It may be difficult, but it is important to tell your partner as soon as possible if you believe you may have an STD. Even if you are being treated, you may still be able to spread the infection. For some STDs, it's recommended that both partners be treated at the same time. It can be difficult to share this information, so some people find that preparing a script in advance can be helpful. Here are some facts that can help the conversation go more smoothly:

Discovering an STD is not evidence of cheating. It may very well have come from one of yours or your partner's past relationships.
An estimated one in two sexually active people will contract an STD by the time they reach age 25. Most of these don't know they have an STD. Many STDs show few or no symptoms when contracted and may be discovered much later.

It's normal to be nervous about this topic. But by being bold and taking action, you can actively promote better health for you and your partner.
STDs and Pregnancy
Photo of ultrasound of baby.

STDs can cause premature labor in pregnant women, and many STDs can be passed to the baby either during pregnancy or childbirth. So all pregnant women should be checked for STDs. STDs can cause numerous problems in babies, like low birth weight, stillbirth, nerve problems, blindness, serious infections, and liver problems. Treatment during pregnancy can reduce the risks of these complications and can cure many types of infections.
Can STDs Come Back?

In most cases, new exposures to STDs that you have had in the past can cause you to get the infection again. Most treatments don't protect you from developing the STD at a future time. If your partner has not been treated, you may pass the infection back and forth. Without the right precautions, you could acquire a second STD or a recurrence of the same infection. In addition, genital herpes virus infections can be recurrent after a single exposure.

Some experts prefer to term STD's as STIs (sexually transmitted infections). STIs include all infections that can be transmitted sexually. For example, scabies and most recently, Zika virus infections are better classified as STIs.

Diseases & Conditions
Female Sexual Dysfunction

Sexual Dysfunction is Common
slide.ImageAlt

Sexual dysfunction is a common concern shared by many women. Problems may occur during any phase of the sexual response cycle (excitement, plateau, orgasm, and resolution) that prevent a woman from experiencing sexual satisfaction. Many women are reluctant or embarrassed to discuss their sexual problems, but it's important to tell your doctor what you are experiencing since most cases of sexual dysfunction can be treated.
What Causes Female Sexual Problems?
slide.ImageAlt

Sexual dysfunction can have physical or psychological causes. Physical causes include diabetes, heart disease, neurological diseases, hormonal imbalances, menopause, chronic diseases such as kidney disease or liver failure, alcoholism, drug abuse, and side effects of medications, including antidepressant drugs. Psychological causes of sexual dysfunction can include stress, anxiety, concerns about sexual performance, relationship problems, depression, feelings of guilt, and effects of a past sexual trauma.
Who Is Affected by Sexual Problems?
slide.ImageAlt

Men and women can be affected by sexual dysfunction. Seniors may be affected more often, possibly due to health-related declines associated with aging.
How Do Sexual Problems Affect Women?
slide.ImageAlt

Common types of sexual dysfunction in women include:

Inhibited sexual desire
Inability to become aroused
Lack of orgasm (anorgasmia)
Painful intercourse

These will be discussed on the following slides.
Inhibited Sexual Desire
slide.ImageAlt

Lack of sexual desire or lack of interest in sex is inhibited sexual desire. This can have many causes, including hormonal changes, certain medical conditions and treatments, depression, pregnancy, stress, fatigue, lifestyle influences such as work stress or child care, and even boredom with regular sexual routines.
Inability to Become Aroused
slide.ImageAlt

Insufficient vaginal lubrication in women may trigger the inability to become physically aroused during sexual activity. An inability to be aroused may also result from anxiety, or inadequate sexual stimulation. Blood flow problems to the vagina and clitoris may also affect lubrication and arousal.
Lack of Orgasm (Anorgasmia)
slide.ImageAlt

The absence of sexual climax (orgasm) is called anorgasmia. Many factors can contribute to anorgasmia, including sexual inhibition, inexperience, or lack of knowledge. Psychological contributors to anorgasmia may include guilt, anxiety, or a past sexual trauma or abuse. Insufficient stimulation, drugs or medications, and chronic diseases can also result in lack of orgasm.
Painful Intercourse
slide.ImageAlt

Painful intercourse can be a result of a number of conditions such as endometriosis, a pelvic mass, ovarian cysts, vaginitis, poor lubrication, vaginal dryness, the presence of scar tissue from surgery, or a sexually transmitted disease. A painful, involuntary spasm of the muscles that surround the vaginal entrance is a condition called vaginismus that may occur in women who fear penetration will be painful, have sexual phobias, or previous traumatic or painful sexual experiences.
How Is a Female Sexual Problem Diagnosed?
slide.ImageAlt

Sexual dysfunction in women is diagnosed by a physical exam and symptom history. The doctor will probably perform a pelvic exam with a Pap smear to check for cancer. Other tests may be ordered to rule out medical conditions that may cause sexual dysfunction. You may also be asked about attitudes toward sex, past sexual trauma or abuse, problems in your relationship, or alcohol and drug abuse to help determine if these psychological factors contribute to the dysfunction.
How Are Female Sexual Problems Treated?
slide.ImageAlt

Many types of sexual problems can be treated by addressing the underlying physical or psychological problems. Usually it involves cooperation between the woman, her doctors, and therapists.

Treatment strategies are discussed on the following slides.
Providing Education
slide.ImageAlt

Patient education is important to help women overcome anxiety about sexual function and performance. Learning about sexual behaviors and normal responses may ease anxiety.
Enhancing Sexual Stimulation
slide.ImageAlt

It may be necessary to enhance sexual stimulation to help a woman overcome some sexual dysfunction. Masturbation, changing your sexual routine, or use of erotic videos or books may help.
Providing Distraction Techniques
slide.ImageAlt

Anxiety may be alleviated with distraction. Erotic or non-erotic fantasies can be useful. Music, videos, or television can also distract and help women relax.
Encouraging Non-Coital Behaviors
slide.ImageAlt

Other behaviors that do not involve intercourse such as sensual massage may help a women feel more comfortable with her sexuality and with intercourse, and feel less pressure and anxiety surrounding sexual activity.
Minimizing Pain
slide.ImageAlt

If sexual dysfunction is due to pain, sometimes changing sexual positions may help minimize or eliminate the pain. Vaginal lubricants may relieve pain caused by friction, and relaxation before intercourse (warm bath, meditation) may decrease pain responses.
Can Sexual Problems Be Cured?
slide.ImageAlt

The prognosis for treating sexual dysfunction in women depends on whether the underlying cause can be treated. If sexual dysfunction is related to a treatable physical condition, the outcome is often positive. When dysfunction is due to psychological causes, it can often be treated successfully with counseling, education, and improved communication between partners.
How Do Hormones Affect Sexual Function?
slide.ImageAlt

Hormones play a large role in sexual function in women. As women age, the hormone estrogen decreases, which can lead to poor vaginal lubrication and decreased genital sensation. Low levels of the male hormone testosterone in women may also contribute to less sexual arousal, genital sensation, and orgasm.
What Effect Does a Hysterectomy Have on Sexual Function?
slide.ImageAlt

A hysterectomy (surgical removal of the uterus) may cause sexual dysfunction in many women. Hormonal changes associated with removal of the ovaries may result in loss of desire, decreased vaginal lubrication, and genital sensation. Nerves and blood vessels integral to sexual functioning may also be damaged during the surgery. Finally, some women may become depressed or feel a loss of self-esteem from their uterus being removed that may make it hard for them to engage sexually following the procedure.
How Does Menopause Affect a Woman's Sexual Function?
slide.ImageAlt

Menopause and the associated loss of estrogen can affect women's sexual function such as a loss of vaginal lubrication and genital sensation. Other emotional aspects of menopause may contribute to a loss of interest in sex or an inability to become aroused.

However, many postmenopausal women have increased sexual satisfaction. This is thought to be due to less anxiety about getting pregnant, or having the time to relax and enjoy being intimate with their partners.
When Should I Call my Doctor About Sexual Problems?
slide.ImageAlt

Sexual problems in women are common, and nearly every woman will experience them on occasion. If the problems persist, they can be very upsetting for a woman and can affect her relationship with her partner. If you experience any sexual problems on a regular basis, talk to your doctor.
