Vaginal lubrication is the naturally produced lubricating fluid that reduces friction during sexual intercourse. Lubrication is the process or technique employed to reduce wear of one or both surfaces in close proximity and moving relative to each another by interposing a substance called Sexual intercourse, in its biological sense is the act in which the male reproductive organ (in humans and other higher animals enters the female reproductive tract It is often produced on occasions of women's sexual arousal.
The Bartholin's glands, located slightly below and to the left and right of the opening of the vagina, secrete mucus to provide lubrication. The Bartholin's glands (also called Bartholin glands or greater vestibular glands) are two Glands located slightly below and to the left and right of the
Vaginal dryness is the condition in which this lubrication is insufficient.

Composition
The lubrication fluid contains water, pyridine, squalene, urea, acetic acid, lactic acid, complex alcohols and glycols, ketones, and aldehydes. Water is a common Chemical substance that is essential for the survival of all known forms of Life. Pyridine is a Chemical compound with the formula C5[[Hydrogen H5]] N. Squalene is a natural Organic compound originally obtained for commercial purposes primarily from Shark liver oil, though there are botanic sources as well including Urea is an Organic compound with the Chemical formula ( N[[hydrogen H]]22 C[[oxygen O]] Acetic acid, also known as ethanoic acid, is an organic chemical compound, giving Vinegar its sour taste Lactic acid ( IUPAC Systematic name: 2-hydroxypropanoic acid) also known as milk acid, is a Chemical compound that plays a role In Chemistry, an alcohol is any Organic compound in which a Hydroxyl group ( - O[[hydrogen H]]) is bound to a Carbon A diol or glycol is a Chemical compound containing two Hydroxyl groups (-OH groups Vicinal diols have hydroxyl groups attached to adjacent atoms A ketone (pronounced as key tone) is either the Functional group characterized by a Carbonyl group (O=C linked to two other Carbon atoms or An aldehyde is an organic compound containing a terminal Carbonyl group. [1] The fluid is typically clear and more resembling of male pre-ejaculate than male ejaculate. Ejaculation is the ejecting of Semen from the Penis, and is usually accompanied by Orgasm. It can vary in consistency, texture, color, and odor, depending on sexual arousal, the time of the menstrual cycle, the presence of an infection, genetic factors and diet. Texture refers to the properties held and sensations caused by the external surface of objects received through the sense of touch. The menstrual cycle is a recurring cycle of physiologic changes that occurs in reproductive-age Females Overt menstruation (where there is blood flow from the An infection is the detrimental Colonization of a host Organism by a foreign Species.

Vaginal fluid is slightly acidic and can become more acidic with certain sexually transmitted diseases. A sexually transmitted disease ( STD) or venereal disease ( VD) is an illness that has a significant probability of transmission between Humans The normal pH of vaginal fluid is between 3. 8 and 4. 5,[2][3] whereas male semen is typically between 7. Physiological aspects Internal and external fertilization Depending on the Species, spermatozoa can fertilize 2 and 8. 0 (a neutral substance has a pH of 7. 0)[4].
Changes in vaginal lubrication
Certain medications, including some over-the-counter antihistamines, as well as life events such as pregnancy, lactation, menopause, aging or diseases such as diabetes, will inhibit lubrication. A histamine antagonist is an agent which serves to inhibit the release or action of Histamine. Lactation describes the secretion of Milk from the Mammary glands the process of providing that milk to the young and the period of time that a Mother Menopause is the permanent shutting down of the female Reproductive system, a considerable length of time before the end of the lifespan Senescence refers to the biological processes of a living Organism approaching an advanced age (i Diabetes mellitus (ˌdaɪəˈbiːtiːz or /ˌdaɪəˈbiːtəs/ /məˈlaɪtəs/ or /ˈmɛlətəs/ often referred to simply as diabetes ( Ancient Greek: grc Medicines with anticholinergic or sympathomimetic effects will dry out the "mucosal" or wet tissues of the vagina. An anticholinergic agent is a substance that blocks the Neurotransmitter acetylcholine in the central and the Peripheral nervous system. Sympathomimetic drugs are substances that mimic the effects of the Catecholamines Epinephrine (adrenaline Norepinephrine (noradrenaline and/or The vagina (from Latin, literally " Sheath " or " Scabbard " is a fibromuscular tubular tract leading from the Uterus Such medicines include many common drugs for allergic, cardiovascular, psychiatric, and other medical conditions.

Role in disease transmission
Safe sex educators warn that the vaginal fluids of a woman who is infected with HIV or other STIs can transmit the disease, even in the absence of direct penile-vaginal sexual intercourse, so direct contact is discouraged. Safe sex (also called safer sex or protected sex) is the practice of Sexual activity in a manner that reduces the risk of Infection with Human immunodeficiency virus ( HIV) is a Lentivirus (a member of the Retrovirus family that can lead to acquired immunodeficiency syndrome A sexually transmitted disease ( STD) or venereal disease ( VD) is an illness that has a significant probability of transmission between Humans
Artificial lubrication
When natural lubrication is insufficient, penetrative intercourse may be uncomfortable or painful. A personal lubricant applied to the vaginal opening and/or the penis can prevent this discomfort. Personal lubricants are specialized Lubricants which serve during sexual intercourse to reduce Friction with the Vagina, the Anus, or other More rarely, a vaginal suppository may be inserted prior to intercourse. A suppository is a drug delivery system that is inserted either into the Rectum (rectal suppository Vagina (vaginal suppository or Urethra (urethral Sexual intercourse, in its biological sense is the act in which the male reproductive organ (in humans and other higher animals enters the female reproductive tract
Oil-based lubricants can weaken latex and reduce the effectiveness of condoms, latex gloves, or dental dams as either forms of birth control or for protection from sexually transmitted diseases, so water- or silicone-based lubricants are often used instead. Personal lubricants are specialized Lubricants which serve during sexual intercourse to reduce Friction with the Vagina, the Anus, or other A condom is a device most commonly used during Sexual intercourse. Dental dams or rubber dams are rectangular sheets of Latex used in Dentistry, specifically Endodontic therapy. Birth control, sometimes synonymous with contraception, is a regimen of one or more actions devices or Medications followed in order to deliberately prevent A sexually transmitted disease ( STD) or venereal disease ( VD) is an illness that has a significant probability of transmission between Humans Personal lubricants are specialized Lubricants which serve during sexual intercourse to reduce Friction with the Vagina, the Anus, or other Personal lubricants are specialized Lubricants which serve during sexual intercourse to reduce Friction with the Vagina, the Anus, or other
