Top Pheromones Odors

In squirrel monkeys (Saimiri sciureus) Latta et al. (1967) noted increased pheromone washing behavior in receptive females under laboratory conditions and reported that males frequently smelled the genitalia and bodies of females and the places where they had urine washed. Baldwin (1970), who studied a seasonally breeding group of Saimiri under seminatural conditions, reports that there is an increase in olfactory investigation of females by males during the breeding season.

Males, however, are attracted to female odors whether the female is in estrus or not, although the scent of estrus females seems to have stronger attraction. He suspects that female odors might stimulate the males and bring them into the reproductively active condition. In laboratory groups, where males and females are caged together, the males are permanently exposed to female pheromone odors. Discover more about pheromones

This would explain why the males of many laboratory colonies are more or less sexually active all year round (Latta et al. 1967). In free ranging groups, however, adult males travel separately from the females except during the breeding season, when they are spermatogenic (Baldwin 1968).\As female odors become more attractive during the breeding season, they might motivate the males to interact with the females and thus be exposed to the stimulating effect of female pheromones (Baldwin 1970).

Vandenbergh (1969) induced sexual activity in male rhesus monkeys (Macaca mulatta) by exposing them to ovariectomized, estrogenized females during the nonbreedingseason. The monkeys were captured from a free-ranging group on an island near Puerto Rico’s southwestern coast and remained exposed to their normal environmental conditions during the experiments. No sexual behavior was recorded at the same time in the free-ranging animals not involved in the experiment. Rose et al. (1971, 1972) have recently shown that .plasma testosterone levels in male rhesus monkeys increase with social rank and sexual activity. Although no direct evidence exsits regarding pheromones according to

 The likelihood that there are functional human pheromones has been both asserted (Wilson 1963; Wiener 1966, 1967a, 1967b) and denied (Gleeson and Reynierse 1969), both without direct experimental evidence: the finding of clear pheromonal effects in monkeys (Michael and Saayman 1967; Michael and Keverne 1970) and the recent observation of menstrual synchronization between close friends (McClin- tock 1971) re-open the possibility more definitely, and make direct experiment obligatory.

The practical importance of such research lies in the possibility of primer con- trol over human endocrine cycles and reproduction generally; if this exists, it might open a new chapter in reproductive pharmacology at a time when it is badly needed. Compared with~drugs, pheromones are strikingly economical in quantity, many operating at a level of molecules rather than milligrams. Even the study of simple ‘releaser’ effects could clarify a field of human, and especially developmen- tal, biology which has been so far suspected rather than elucidated. Odor finger- printing techniques and gas chromatography (Dravnieks and Krotoszynski 1970) now make the detection and preparation of human pheromonal agents feasible if they exist. Learn at

Sexual releaser effects of odor in man have been recognized throughout human experience, even in cultures which found the idea embarrassing, and the richness of human olfactosexual behavior was fully documented by Havelock Ellis (1905).
