Although biopsy is most often associated with cancer, it can also be used to check for other diseases, such as infections. A biopsy sample can be scraped, cut, collected with a needle, taken with a machine that punches out a tiny piece, or removed with the tiny tools in an endoscope.

In most cases, a biopsy is a simple outpatient procedure. Depending on the procedure, patients may need to stop taking certain medications beforehand, such as blood thinners. It is important for patients to tell doctors if they are pregnant, as certain biopsies require the use of x-rays to guide the needle to the right location. There is usually very little pain associated with a biopsy. Patients will have to wait a few days to hear the results.

Sexual intimacy disorders are those that cause problems with the act of sexual intercourse, such as erectile dysfunction or vulvodynia. Erectile dysfunction, the inability to get or maintain an erection hard enough for sexual intercourse, is extremely common. It affects fully half of men over 40 to some degree. It is treated with medications, devices, or surgery. Vulvodynia, burning pain in the vulva that can be made worse with sexal activity, has no known cause. It is treated with oral or topical medications.

Sexually transmitted diseases, including HIV/AIDS, herpes, gonorrhea, and chlamydia, are bacterial or viral infections that are contagious in the bodily fluids exchanged during sexual contact. Barrier methods of contraception, such as condoms, help prevent the spread of STDs. HIV is a virus that can be caught from an infected person's sexual fluids or blood. When the virus infects the body, it interferes with the immune system and causes the disease known as AIDS. There is no cure, but anti-viral medications can help people with AIDS live a long and healthy life. Herpes is also a virus found in sexual fluids, called HSV-2. It causes blisters that come and go on the genitals. There is no cure for herpes, but anti-virals can minimize outbreaks. Gonorrhea and chlamydia are both bacterial infections. They are extremely common and often have no symptoms. The most common signs of an infection are burning pain and discharge. Gonorrhea and chlamydia can be treated with medications.

Reproductive health refers to both contraception and infertility treatment. Contraceptives prevent and plan the timing of pregnancy. Some, such as a vasectomy or tubal ligation, are extremely effective at preventing pregnancy. Others, such as spermicides, are less reliable. Popular contraceptives include condoms, birth control pills, IUDs, and diaphragms. On the other side of reproductive health, infertility is the inability to carry a pregnancy to term after one year of trying. It can be due to problems in either the man or the woman, and both genders are affected equally. In total, about 15% of the population suffer from infertility. Infertility treatments include medications and surgery.

Gay and transgender people have a few specific health care needs that may sometimes fall under the sexual health umbrella. First, many LGBT people still face discrimination from healthcare providers, so providing supportive and appropriate care is an issue. Because of social attitudes surrounding sexual orientation and gender identity, many gay and transgender people struggle with their identities. Rates of depression, substance abuse, and suicide are all higher in this group. Providing mental health support and counseling to those in transition is critical. Finally, transgender patients who are undergoing gender affirmation require sensitive medical health care, including surgical and hormonal treatment.

Sexual violence can be defined as any unwanted or non-consensual sexual activity. It ranges from sexual harassment to touching to rape. It affects women more than men and is widespread: 1 in 4 women report being victims of sexual violence at the hands of a partner, and as many as 1 in 3 girls report their first sexual contact as being violent. Sexual violence has lasting physical and emotional consequences for victims, but educating both girls and boys can prevent violence. Care for those who have endured sexual violence includes counseling and mental health support, medical care, and legal support.

Sexuality is more than a reproductive requirement -- it is a form of expression and identity. Sexual health blends all these aspects of experience together and helps people lead sexually fulfilling lives.

Urinary tract infections are extremely common: 12% of all men and 40-50% of all women will have a urinary tract infection during their lifetime. They are more common in women because women have shorter urethras, so bacteria have a shorter distance to travel from the outside of the body to the bladder and cause an infection. Some people also have urethras that are an unusual shape or have an obstruction in the urethra that makes getting a UTI more likely. Also, certain chronic illnesses like diabetes weaken the immune system, so any bacteria in the body are more likely to cause an infection.

A urinary tract infection can be diagnosed very quickly by a doctor. A sample of urine can be examined under a microscope for the presence of bacteria or white blood cells. There are also diagnostic strips that can be used to test a urine sample without the need for a microscope. Once a diagnosis is made, treatment is a course of oral antibiotics, and most patients feel better within just a few days. There are some things that patients can do themselves to help reduce the risk of getting a urinary tract infection in the future. Stay well hydrated, wipe from front to back after going to the bathroom, wear breathable cotton undergarments, and don't hold it in when patients feel the urge to go.
