Both injection and aspiration are techniques that involve inserting a needle connected to a syringe directly into the joint. Aspiration involves the removal of excess fluid, and injection is the placement of medication directly into the joint space via the needle. Both procedures may be performed at the same time. In both cases a local anesthetic may be used, the skin will be cleaned and disinfected, and then the needle will be inserted. In some cases, especially if the injection or aspiration is in a large and deep joint such as the hip or spine, ultrasound may be used to guide the needle to the exact location desired.

In some cases, irritation to the joint can cause fluid to build up so significantly that the joint hurts and can no longer move well. Aspiration removes some of the excess fluid and relieves the pressure. In addition, aspiration can be used to provide a sample of joint fluid if it needs to be examined microscopically for the presence of white blood cells, bacteria, or crystal formations.

Certain injuries and diseases that affect joints are inflammatory in nature, such as rheumatoid arthritis, tendonitis or gout. These diseases may be helped by the local injection of anti-inflammatory medications directly into the affected joint. In this case, corticosteroids such as methylprednisone are usually used. Relief from the pain may be felt right away and may last for weeks or even months.

In some cases, such as with osteoarthritis, the cartilage buffer between the two bones wears down and pain comes from bones rubbing against each other. In this case, injection of a lubricating agent such as hyaluronic acid may be beneficial. It provides a slippery cushion between the bones to relieve pain that can last for months.

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.
