Androstenol is the scent produced by fresh male sweat, and is attractive to females. Androstenone is produced by male sweat after exposure to oxygen – i.e. when less fresh – and is perceived as highly unpleasant by females (except during ovulation, when their responses change from 'negative' to 'neutral').
The component is androstenone, a steroid derived from testosterone that is present in sweat. To some people, androstenone smells pleasant, with a sweet, floral, or vanilla-like scent.
Yes, changes in hormones can cause your body odor to smell.
The chemical androstenol contributes to the musky smell of body odor. Men produce much more of this chemical than women, and testosterone levels may be linked to production of these molecules, the researchers suggest. If so, the women in the study may be responding to these subtle odor cues.
But androstenone, a derivative of testosterone that is a potent ingredient in male body odor, can smell like either - depending on your genes. While many people perceive a foul odor from androstenone, usually that of stale urine or strong sweat, others find the scent sweet and pleasant.

A person's sweat may smell like vinegar because of health conditions such as kidney disease, diabetes, or skin infections. A person's diet may also influence the way their sweat smells.
Gene found that determines if putative human pheromone smells naughty or nice. The compound androstenone can induce many reactions, depending on who is on the receiving end. For some, it smells sweet, like flowers or vanilla; to others it is foul, like sweat or urine. And then there are those who can't smell it at all.
The chemical androstenol contributes to the musky smell of body odor. Men produce much more of this chemical than women, and testosterone levels may be linked to production of these molecules, the researchers suggest.
Based on research indicating single males have higher testosterone levels than partnered males and that higher testosterone levels are associated with stronger smelling BO, the current study aimed to determine if, by extension of previous findings, single males' BO smells stronger than partnered males' BO.
Men typically have more 'corynebacteria' – the smelly bacteria, in their armpits than women do. Why? Men have thicker skin in their armpits and sweat more fatty substances, which is the perfect recipe for corynebacteria to breed. So actually yes, boys do smell more.
This is because testosterone makes your skin thicker and oilier, which also alters the way your sweat reacts with the bacteria on your skin. As a result, body odor becomes stronger and more distinct.
University of Kent research suggests that men can distinguish between the scents of sexually aroused and non-aroused women. The detection of sexual arousal through smell may function as an additional channel in the communication of sexual interest and provide further verification of human sexual interest.
One of these steroidal compounds, androstadienone, is present at much higher concentrations in male sweat and can be detected by women, albeit with wide variation in sensitivity.
Men and women are attracted to the pheromones they produce and HLA is related to the perceptions of other peoples' odours. Males produce androstenol and androstenone.
But can we smell ourselves? For the first time, scientists show that yes, we can, ScienceNOW reports. Our basis of self-smell originates in molecules similar to those animals use to chose mates.
Body odor at night rarely tops the list of serious health woes, but it can be embarrassing and disconcerting. Sour body odor when sleeping usually isn't a cause for concern, but the sweating could be a sign of benign hyperhidrosis or a more serious ailment.
Because men tend to have more hair on their bodies, including the armpits. There may be more bacteria in these hair follicles. When the body sweats, the bacteria that is present in those areas will feed off the sweat released from the body causing it to smell worse than other areas of the body.
Although there is some controversy on the subject of "racial" variation in body odor, it is determined that African blacks probably produce the greatest amount of apocrine sweat, which is the known substrate for axillary odor.
About Pheromones
Male pheromones are the body's natural sex hormones that attract women in a sexual manner to that man on a subconscious level, especially during certain points of the female's menstrual cycle.
Blood samples were taken to establish where they were in their menstrual cycles. The result: women who were close to ovulation were perceived to smell more attractive to the men. The higher the estrogen levels in the women's blood, the better the scent was judged to be.
