Safe sex is sexual activity using methods or contraceptive devices to reduce the risk of transmitting or acquiring sexually transmitted infections (STIs), especially HIV. "Safe sex" is also sometimes referred to as safer sex or protected sex to indicate that some safe sex practices do not eliminate STI risks. It is also sometimes used colloquially to describe methods aimed at preventing pregnancy that may or may not also lower STI risks.
Vaginitis, also known as vulvovaginitis, is inflammation of the vagina and vulva. Symptoms may include itching, burning, pain, discharge, and a bad smell. Certain types of vaginitis may result in complications during pregnancy.
Spermicide is a contraceptive substance that destroys sperm, inserted vaginally prior to intercourse to prevent pregnancy. As a contraceptive, spermicide may be used alone. However, the pregnancy rate experienced by couples using only spermicide is higher than that of couples using other methods. Usually, spermicides are combined with contraceptive barrier methods such as diaphragms, condoms, cervical caps, and sponges. Combined methods are believed to result in lower pregnancy rates than either method alone.
Microbicides for sexually transmitted infections are pharmacologic agents and chemical substances that are capable of killing or destroying certain microorganisms that commonly cause sexually transmitted infection.
Vaginal lubrication is a naturally produced fluid that lubricates the vagina. Vaginal lubrication is always present, but production increases significantly near ovulation and during sexual arousal in anticipation of sexual intercourse. Vaginal dryness is the condition in which this lubrication is insufficient, and sometimes artificial lubricants are used to augment it. Without sufficient lubrication, sexual intercourse can be painful. The vaginal lining has no glands, and therefore the vagina must rely on other methods of lubrication. Plasma from vaginal walls due to vascular engorgement is considered to be the chief lubrication source, and the Bartholin's glands, located slightly below and to the left and right of the introitus, also secrete mucus to augment vaginal-wall secretions. Near ovulation, cervical mucus provides additional lubrication.
Personal lubricants are specialized lubricants used during sexual acts, such as intercourse and masturbation, to reduce friction to or between the penis and vagina, anus or other body parts or applied to sex toys to reduce friction or to ease penetration. Surgical or medical lubricants or gels, which are similar to personal lubricants but not usually referred to or labelled as "personal" lubricants, may be used for medical purposes such as speculum insertion or introduction of a catheter. The primary difference between personal and surgical lubricants is that surgical lubricants are thicker, sterile gels, typically containing a bacteriostatic agent. As of 2015 the personal lubricant market was estimated to be worth at least $400 million.
Dry sex is the sexual practice of having sexual intercourse without vaginal lubrication. Vaginal lubrication can be removed by using herbal aphrodisiacs, household detergents, antiseptics, by wiping out the vagina, or by placing leaves in the vagina besides other methods. Dry sex is associated with increased health risks.
Pre-exposure prophylaxis for HIV prevention, commonly known as PrEP, is a form of pre-exposure prophylaxis to prevent HIV infection, the cause of HIV/AIDS.
A sexually transmitted infection (STI), also referred to as a sexually transmitted disease (STD) and the older term venereal disease (VD), is an infection that is spread by sexual activity, especially vaginal intercourse, anal sex, oral sex, or sometimes manual sex. STIs often do not initially cause symptoms, which results in a risk of passing the infection on to others. Symptoms and signs of STIs may include vaginal discharge, penile discharge, ulcers on or around the genitals, and pelvic pain. Some STIs can cause infertility.
A douche is a device used to introduce a stream of water into the body for medical or hygienic reasons, or the stream of water itself. Douche usually refers to vaginal irrigation, the rinsing of the vagina, but it can also refer to the rinsing of any body cavity. A douche bag is a piece of equipment for douching—a bag for holding the fluid used in douching. To avoid transferring intestinal bacteria into the vagina, the same bag must not be used for an enema and a vaginal douche.
iPrEx was a phase III clinical trial to determine whether the antiretroviral medication emtricitabine/tenofovir could safely and effectively prevent HIV acquisition through sex in men who have sex with men and transgender women. iPrEx was the first human study of an HIV prevention strategy known as pre-exposure prophylaxis, or PrEP.
CAPRISA 004 is the name of a clinical trial conducted by CAPRISA. This particular study was the first to show that a topical gel could reduce a person's risk of contracting HIV. The gel used in the study contained a microbicide.
CONRAD is a non-profit organization scientific research organization that works to improve the reproductive health of women, especially in developing countries. CONRAD was established in 1986 under a cooperative agreement between Eastern Virginia Medical School (EVMS) and the United States Agency for International Development(USAID). CONRAD’s products are developed primarily for women in low-resource settings, in that they are designed to be safe, affordable and user-friendly. CONRAD is led by Scientific and Executive Director Gustavo Doncel, M.D., Ph.D. Primary funding for CONRAD comes from the U.S. President's Emergency Plan for AIDS Relief (PEPFAR) through the U.S. Agency for International Development (USAID), with additional funding from The Bill & Melinda Gates Foundation and the National Institutes of Health (NIH).
HIV prevention refers to practices that aim to prevent the spread of the human immunodeficiency virus (HIV). HIV prevention practices may be undertaken by individuals to protect their own health and the health of those in their community, or may be instituted by governments and community-based organizations as public health policies.
A rectal microbicide is a microbicide for rectal use. Most commonly such a product would be a topical gel inserted into the anus so that it make act as protection against the contract of a sexually transmitted infection during anal sex.
PRO 2000 is an experimental vaginal microbicide which has been proposed as a preventive medicine for reducing the risk of contracting HIV. It has never been recommended as an effective medicine to be used for any purpose. Some clinical trials have shown that under some conditions it may provide some protection against HIV.
Multipurpose prevention technologies (MPTs) are a class of products designed to address at least two health issues simultaneously, often focusing on sexual and reproductive health which includes contraception, human immunodeficiency virus (HIV) prevention, other sexually transmitted infection (STI) preventions, such as genital infection by human simplex virus (HSV) infection and human papillomavirus (HPV) infection. For example, MPTs can combine contraception and HIV prevention, contraception and other STI prevention, or the prevention of multiple STIs. Since the simultaneous use of multiple products with a single indication against each specific sexual and reproductive health issue is inconvenient, this method may affect adherence. As a result, the goal of developing a MPT as an all-in-one product is to combat this issue.
Elizabeth Anne Bukusi FAAS is a research professor working within the field of obstetrics and gynaecology, and global health. Bukusi's main areas of research focus around sexually transmitted infections, women's health, reproductive health, and HIV care, prevention and treatment. Bukusi is the Chief Research Officer at the Kenya Medical Research Institute (KEMRI) and led a "landmark" study on the use of PrEP in Kenya.
Dapivirine (DPV) Ring is an antiretroviral vaginal ring pioneered by the International Partnership for Microbicides (IPM) pending for regulatory review. It is designed as a long-acting form of HIV prevention for at-risk women, particularly in developing nations such as sub-Saharan Africa. IPM has rights to both the medication and the medical device. A total of four rings with different drug diffusion systems and polymer composition have been developed by IPM. The latest design, Ring-004, is a silicone polymer matrix-type system capable of delivering DPV intravaginally in a sustained manner.
