Sexual excitation

To date, the females of more than 150 species of insects have been reported to produce a sex attractant or excitant for the male, and males of more than 50 species have been shown to produce such materials to attract or sexually excite the females (39). Table I lists insect pests of the order Lepidoptera in which the occurrence of sex attractants has been reported since 1960. In addition, investigators... 

Some 19th century writers reported about cases of distinctive body odour emanating after sexual excitement or coitus (Gould and Pyle 1896). According to our knowledge this question has not been addressed in any empirical study yet.

Homosexuality is sexual inversion in which orientation is towards individuals of the same gender. The term sexual orientation refers to a personal potential to respond with sexual excitement to persons of the same sex, the opposite sex or both. 

Small doses of cocaine can cause users to feel both mentally and sexually excited, self-confident, uninhibited, talkative, clever, and in control. Larger doses and heavy use can cause the opposite effects. Heavy users can become confused mentally, uninterested in sex, paranoid (feeling everyone is against them), antisocial, aggressive, and are subject to cocaine psychosis (a mental illness whose symptoms include paranoia, disorientation, and severe depression). 

Diptera. Cuticular hydrocarbons derived from females have been reported to function as short range sex attractants for all the species of flies that have been examined. (Zj-9-Tricosene was identified as the sex pheromone of the house fly, Musca domestica, whereas C27 and C29 cuticular monoolefins were only weakly active (42). Furthermore, (Z)-9-tricosene was reported to function as a sexual excitant as well, since the incidence of copulatory attempts by male flies was reported to be increased in the presence of this compound. It was subsequently suggested that (Z)-9-heneicosene was an orientation pheromone for male flies, and a 7 3 ratio of the C23 and C21 alkenes was optimal in terms of orientation and mating behavior (43). However, neither hydrocarbon increased the attraction of male flies to moving dummies (44), and it was eventually concluded that these long-chain (zj-9-alkenes functioned primarily as psychedelics with regard to visually stimulated sex attraction and aggregation (45). 

In June 2004 James Pfaus of Concordia University, Montreal, published a paper in the on-line edition of the Proceedings of the National Academy of Science USA announcing that the a protein molecule coded PT-141 not only causes erections in men but also sexually excites female rats. When it was given to these rodents they be... 

Sensuality and Sexuality. MDMA, often called a "hug drug," has a deserved reputation in this arena. It increases intimacy, but in most instances tends to reduce genital sexuality. The standard finding about this substance was expressed by John Buffum and Charles Moser in the October 1985 Journal of Psychoactive Drugs when they reported on the first survey of MDMA s effects on human sexuality. "It appears that MDMA does not increase sexual excitation or sexual desire in a majority of individuals," they wrote,... 

The authors suggested that acute sexual excitement during cocaine intoxication can cause penile erection, with impaired detumescence. Cocaine can inhibit the reuptake of noradrenaline (by blocking transport in presynaptic sympathetic neurons), thus preventing sinusoidal contraction and the efflux of penile blood.

The unstimulated vagina anatomically consists of a luminal space that exists potentially rather than actually. However, in response to sexual excitement, some tension-induced anatomic variations occur. These anatomic variations may have effects on the long-term intravaginal delivery systems. These variations are reflected in the existence of four phases in a sexual response cycle as outlined by Masters and Johnson. ... 

Can you imagine how good you would feel to be able to walk up to anyone you find attractive and instantly create that deep sense of connection, rapport, sexual excitement If in the past, you have left chemistry to chance, you are in for abig surprise. Read On. 

Symptoms are complaints, always real to the complainant. Many complaints that meet the authors definition of psychogenic symptom—for example, unrelieved sexual excitement or suppressed rage provoked by a gratuitous insult—do not qualify as illnesses, unless every unwanted experience be regarded as an illness. 

Bombykol is an estrogenic hormone ((I0E,12Z)-hexadecadiene-l-ol) which induces sexual excitement in a male silkworm. Bombykol is prepared by the hydroboration of acetylene compounds with a catecol boron compound and a cross coupling reaction with palladium catalyst, etc., as shown in Scheme 6.4 [41—47], The organoboron compounds are used for leucotriene intermediates [48], L-ribose and amino acids [47], etc., as the others. 

Sexual function Sexual behavior and sexual dysfunction have been explored in 60 patients taking buprenorphine (n = 30) or methadone maintenance treatment ( = 30). Those who took methadone had more problems with sexual excitation (33% versus 3.3%) and difficulty in reaching orgasm (40% versus 10%) than those who took buprenorphine. Sexual satisfaction was also significantly greater in those who used buprenorphine (90% versus 63%) [12"]. 

In males, NO is the messenger that translates sexual excitement into an erect penis. This is brought about by the dilation of blood vessels supplying the penis and relaxation of the muscles of the corpora cavernosa — the cavities that the blood fills. The latter effect, initiated by release of NO, results in increased levels of cyclic GMP. Indeed, experiments have shown that rats can be rendered impotent by administering chemicals that impede production of NO. To combat impotence (erectile dysfunction) the drug Viagra is widely prescribed. Its function is to inhibit the enzyme phosphodiesterase, which is responsible for the degradation of cyclic GMP in the corpora cavernosa.
