The pheromonal sub communication level. You realise that human pheromones are considerably less important than the tiny micro-level cues you give off which are basically driven by the your identity and your state at any given moment according to
These pheromone cues normally imprint themselves on others at an intuitive level. We have all been in situations where someone strikes us as “shifty”, or “dishonest”, or “too keen” and so on these are instinctive emotional responses created by our intuition as it reacts to subtle cues. We can’t always verbalise what is creating this impression but we feel it.  The apparent disconnect between what they think you should be doing to get the girl and what is actually happening challenges their reality when they apply pheromone cologne to their neck and wrists.
Pheromone Studies In Animals
In contrast to voles Syrian and Turkish male hamsters show a strong preference for a close female family member over females that are not related. Foster rearing modifies the preference, but does not eliminate it. This phenomenon is clearly a pheromone odor preference based on vomeronasal function (Murphy, 1930).
In further support for pheromone odor conditioning responses, Nyby (1973). in an excellent review, have presented evidence in varied species ranging from house mice to dogs and deer where certain infant and adult encounters are necessary for natural odors (famlllal) or foreign odors to be preferred or avoided. These odors condition behavior. repeated this in 1986, in rats. Perfuming sexually available female rats for their first heterosexual encounter conditions adult male rats to react vocally to the artificial perfume odor in similar fashion to their response to female urine (Nyby, 1978). The female urine stimulus is lost unless reinforced by an active female sexual response (Dizinno, 1978) that permits mounting.
Another female hormone, progesterone, given in the same rat model decreases sexual attractiveness (Thody, 1981). Progesterone is produced during the post-ovulatory period in women, during the two-week period prior to menstruation, or during pregnancy. Progesterone is used with estrogen in birth control. Does it have any affect on human pheromonal attractiveness? Learn more about pheromones at
Of interest to vaginal pheromonal effects, both the hamster (Singer, 1976) and rat (Gawienoski & Stacewicz-Sapuntzakis, 1978), is attracted to sulfur—containing compounds which are among the volatiles also given off by the human body (Ellin, 1974.) Check out these pheromones for men at
The urine of mature male rodents accelerates puberty in females, while female urine (Drickamer, 1977) exposure delays puberty. In rats, the Hex-stimulating female must be new to the male (Tiepir, 1965). In a two choice odor preference test, male rats prefer a strange female to the odor of a previously monogamous mate. The female, in contrast, preferred the odor of the male with which she was monogamously coupled (Carr, I980). Male rats may be behaving more like the stereotype of their male human counterparts.

In relation to pheromonal odor similarities between rodents and humans, during the menstrual cycle, there is a difference in olfactory sensitivity to exatolide (pentadecanolide), a perfume fixative with a musk-like odor (Vlerline & Rock, 1967). This is similar to what has been seen for hours.
