Aphrodisiac

An aphrodisiac is a substance that, when consumed, increases sexual desire.[1][2] Aphrodisiacs are distinct from substances that address fertility issues such as impotence or secondary sexual (dys)function such as erectile dysfunction (ED).

The name comes from the Greek ἀφροδισιακόν, aphrodisiakon, i.e. "sexual, aphrodisiac", from aphrodisios, i.e. "pertaining to Aphrodite",[3][4] the Greek goddess of love.

Assessment of aphrodisiac qualities

Throughout history, many foods, drinks, and behaviors have had a reputation for making sex more attainable and/or pleasurable. However, from a historical and scientific standpoint, the alleged results may have been mainly due to mere belief by their users that they would be effective (placebo effect). Likewise it is noteworthy that many medicines are reported to affect libido in an inconsistent or idiopathic ways: enhancing or diminishing overall sexual desire depending on the situation of subject. This further complicates the assessment process. For example, Bupropion (Wellbutrin) is known as an antidepressant that can counteract other co-prescribed antidepressants' libido-diminishing effects. However, because Wellbutrin only increases the libido in the special case that it is already impaired by related medications, it is not generally classed as an aphrodisiac.

Classically, to be considered an aphrodisiac, a substance should:

  • Be administered orally
  • Reliably increase libido or sexual desire (no placebo effect, no diminishment of libido)
  • Take effect in a relatively immediate time frame (minutes or hours, not days or weeks)

Aphrodisiacs

Testosterone

Libido is clearly linked to levels of sex hormones, particularly testosterone.[5] When a reduced sex drive occurs in individuals with relatively low levels of testosterone[6] (e.g., post-menopausal women or men over age 60[7]), testosterone supplements will often increase libido. Approaches using a number of precursors intended to raise testosterone levels have been effective in older males,[8] but have not fared well when tested on other groups.[9]

Bremelanotide

Some compounds that activate the melanocortin receptors MC3-R and MC4-R in the brain are effective aphrodisiacs. One compound from this class, bremelanotide, formerly known as PT-141, is undergoing clinical trials for the treatment of sexual arousal disorder and erectile dysfunction. It is intended for both men and women. Preliminary results have proven the efficacy of this drug,[10] however development was suspended[11] due to a side effect of increased blood pressure observed in a small number of trial subjects who administered the drug intra-nasally. On 12 August 2009, Palatin, the company developing the drug, announced positive results (none of the previous heightened blood pressure effects were observed) of a phase I clinical study where trial subjects were instead administered the drug subcutaneously.[12] Palatin is concurrently developing a related compound they call PL-6983.

Melanotan II

Melanotan II, bremelanotide's precursor, has been demonstrated to have aphrodisiac properties.[13][14][15]

Crocin

As per a new study, crocin has demonstrated the properties of an aphrodisiac in rats.[16]

Phenethylamines

Phenethylamine (PEA) present in many food compounds as well as the human body is an aphrodisiac; however, this compound is quickly degraded by the enzyme MAO-B and so it is unlikely that any significant concentrations would reach the brain without a monoamine oxidase inhibitor.

Amphetamine and methamphetamine are phenethylamine derivatives which are known to increase libido and cause frequent or prolonged erections as potential side effects, particularly at high supratherapeutic doses where hyperarousal and hypersexuality can occur.[17][18][19] Methamphetamine markedly enhances sexual desire in some individuals,[20] and an entire sub-culture known as party and play is based around sex and methamphetamine use.[19]

Other drugs

Drugs that act on the mesolimbic dopamine pathway, which includes psychostimulants like cocaine and methylphenidate, have libido-modifying (usually enhancing) effects which are mediated through increased receptor signaling in the nucleus accumbens.[18][21] Pramipexole is the only dopamine agonist used in medicine as an aphrodisiac, and is sometimes prescribed to counteract the decrease in libido associated with SSRI antidepressant drugs. The older dopamine agonist apomorphine has been used for the treatment of erectile dysfunction, but is of poor efficacy and has a tendency to cause nausea. Other dopamine agonists such as bromocriptine and cabergoline may also be associated with increased libido, as can the dopamine precursor L-Dopa, but this is often part of a spectrum of side effects which can include mood swings and problem gambling and so these drugs are not prescribed for this purpose.

The libido-enhancing effects of dopamine agonists prescribed for other purposes has led to the development of a number of more selective compounds such as flibanserin, ABT-670 and PF-219,061, which have been developed specifically for the treatment of sexual dysfunction disorders, although none of them have yet passed clinical trials.[22]

Recreational use of anticholinergic drugs such as trihexyphenidyl and dicycloverine for their aphrodisiac effects, while relatively uncommon, has been reported.[23]

Non-aphrodisiacs

Some psychoactive substances such as alcohol, cannabis,[24] methaqualone, GHB and MDMA can increase libido and sexual desire. However these drugs are not aphrodisiacs in the strict sense of the definition, as they do not consistently produce aphrodisiac effects as their main action and often actually impair function (hence, Shakespeare's famed statement that alcohol "provokes the desire, but it takes away the performance"[25]). Nonetheless, these drugs are sometimes used to increase sexual pleasure and to reduce sexual inhibition. Anti-erectile dysfunction drugs, such as Viagra and Levitra, are not considered aphrodisiacs because they do not have any direct effect on the libido, although increased ability to attain an erection may be interpreted as increased sexual arousal by users of these drugs.

Aphrodisiac foods and herbs

Foods and herbs which have been claimed to be aphrodisiacs include:

In popular culture

The invention of an Aphrodisiac is the basis of a number of films including Perfume: The Story of a Murderer, Spanish Fly, She'll Follow You Anywhere and Love Potion No. 9. The first segment of Woody Allen's Everything You Always Wanted to Know About Sex* (*But Were Afraid to Ask) is called "Do Aphrodisiacs Work?", and casts Allen as a court jester trying to seduce the queen. The novel Aphrodesia: A Novel of Suspense centers on an aphrodisiac perfume so powerful that it drives some people to kill their lovers in a fit of insatiable lust.[42]
