Male and female pheromones differ in their chemistry, their dominant production patterns, and their behavioral effects on the people around the wearer. Male-associated compounds (androstenone, androstadienone, androsterone) are testosterone-derived steroids that show up in higher concentrations in male sweat. Female-associated compounds split into two groups: estrogen-derived steroids like estratetraenol, and copulins, a mixture of fatty acids from vaginal secretions. The line between male and female pheromones isn’t strictly binary, since both sexes produce both compound families to some extent, but the dominant-expression patterns are real, the cross-sex effects are well-documented, and the practical implication for pheromone product selection follows from understanding what each compound does rather than from the wearer’s own sex.
What follows breaks down the specific compounds in each group, why the male/female line is fuzzier than the marketing suggests, what male pheromones do to women and what female pheromones do to men, the same-sex effects most articles skip, and how all of this should shape how a buyer chooses between male-targeted and female-targeted pheromone products.
What Are Male Pheromones?
Male pheromones are the chemical compounds present in higher concentrations in male sweat, semen, and skin secretions, and they share a common origin in testosterone metabolism. The three most-studied (and what people are typically asking about with “what are male pheromones called”) are androstenone, androstadienone, and androsterone.
Androstenone. A steroid found in apocrine sweat, derived from testosterone, present in both sexes but at higher concentration in males. Carries a musky, urine-adjacent character at concentrated doses. Most strongly associated with perceived dominance and presence in social settings.
Androstadienone. Another testosterone-derived steroid, present in male sweat and semen. Almost imperceptible to most noses on its own. Produces measurable effects on women’s mood, cortisol, and physiological arousal, covered in detail later on this page.
Androsterone. A weaker androgen present in male skin chemistry. Cleaner musk than androstenone, broadly described as pleasant. Often paired with androstenone in male-targeted formulations to soften the rawer notes.
Beyond these three, men’s bodies produce trace amounts of estrogen-derived compounds and a range of volatile fatty acids from skin chemistry, but the testosterone-derived steroids are the dominant story in male pheromone research. Each compound is detailed in the compound library, with dose ranges and observational notes from a decade of community use.
What Are Female Pheromones?
Female pheromones split into two compound groups, and that split matters because the two groups operate differently. The first is estrogen-derived steroids, paralleling the testosterone-derived male compounds. The second is a fatty-acid mixture from vaginal secretions, not a steroid story at all.
Estratetraenol. An estrogen-derived steroid, present in female urine and skin chemistry. Effectively odorless to nearly everyone. Studied as a putative female-to-male chemosignal, with effects on men’s mood and brain activity at concentrations well below conscious smell threshold.
Copulins. A mixture of short-chain volatile fatty acids found in vaginal secretions, with composition that varies across the menstrual cycle and peaks near ovulation. Slightly sweet, body-warm, with vaginal undertones at concentration. Researchers including Cutler have documented effects on men’s hormonal and behavioral responses going back to the 1980s.
What pheromones do women produce beyond these? Trace amounts of testosterone-derived steroids (especially androsterone, which exists in female chemistry too), and the same range of skin-bacteria-broken-down volatile fatty acids that contribute to body odor in both sexes. The estrogen-derived steroids and copulins are the dominant story for female pheromones specifically.
Each group has its own behavioral signature, covered in the next two sections.
Why The Male/Female Line Isn’t Strictly Binary
The compounds described above carry male and female labels because of dominant production patterns, not because each sex produces only its own. Both sexes produce both compound families, just at different concentrations.
Men have measurable estratetraenol in their chemistry, and women have measurable androstenone and androstadienone in theirs. The differences are quantitative, with order-of-magnitude differences in concentration in many cases, rather than absolute presence/absence.
What this means in practice: when discussions of “male vs female pheromones” come up, the labels point at the dominant side of a continuum, not at a binary split. A male-targeted formulation is heavy on testosterone-derived compounds because those are what shows up most strongly in male chemistry; a female-targeted formulation leans on estrogen-derived compounds and copulins for the same reason.
This continuum framing matters when buyers consider crossover use. A woman wearing an androstenone-heavy product isn’t introducing chemistry her body doesn’t already produce; she’s amplifying a compound she already has at lower baseline levels. The same logic applies in reverse for a man wearing a copulin-leaning product, though crossover use of female-targeted formulations is less common and less well-studied in real-world settings.
How Male Pheromones Affect Women
The cross-sex effects of male pheromones on women are the most-studied piece of human pheromone research outside the MHC and attraction line.
The single best-replicated finding involves androstadienone. In a 2007 Journal of Neuroscience study from Wyart and colleagues at UC Berkeley, women who sniffed pure androstadienone showed elevated salivary cortisol levels for over an hour, along with improved mood ratings, increased sexual arousal scores, and measurable increases in physiological markers like skin conductance and heart rate. The effect held against control odors and replicated patterns from earlier work by Jacob and McClintock at Chicago.
Earlier Jacob and McClintock 2000 had shown that AND exposure shifted women’s mood ratings in context-dependent ways, with effects that varied across the menstrual cycle. Women near ovulation showed the strongest responses.
Beyond AND specifically, male body odor as a whole produces measurable behavioral effects on women in lab studies. Ovulation-phase women rate male body odor as more pleasant than the same odor at other cycle phases. Some of this is the genetics-of-attraction picture covered on the MHC and attraction page; some is general androgen-driven steroid effects.
What pheromones do women find attractive? The honest answer has more variance than a single number can capture: the Wyart cortisol effect held across a young heterosexual female sample, but older women, women on hormonal birth control, and women in different cultural settings show modulated or different patterns. The broad finding (male AND affects female mood and physiology) holds, while the specific magnitude depends on who, when, and how it’s tested.
How Female Pheromones Affect Men
The cross-sex effects of female pheromones on men have been studied less extensively than the male-to-female direction, but the work that exists points the same way.
Copulin work going back to George Preti’s collaboration with Winnifred Cutler has documented changes in men’s hormonal responses (specifically luteinizing hormone) when men are exposed to female axillary or vaginal volatile compounds. The effects are smaller in magnitude than the AND-on-women cortisol shift, but they are present, replicated, and consistent with the general direction the literature predicts.
Brain-imaging work has added another layer. A 2012 fMRI study from Burke and colleagues showed that AND and EST (the male and female steroid pheromones, respectively) activate different hypothalamic regions in heterosexual men and women. The pattern was sex-differentiated: AND activated specific hypothalamic regions in heterosexual women but not men, while EST showed the reverse pattern. This is suggestive that the receiving brain has wiring tuned to detect opposite-sex chemosignals at a level below conscious awareness.
What pheromones do men find attractive? At the chemistry level, the female compounds described above are the main candidates: estratetraenol and copulins, with cycle-related variation in copulin output making the effect time-sensitive. Men exposed to copulin-rich female axillary samples show small but measurable hormonal and behavioral shifts, particularly in attractiveness ratings of women in subsequent face-rating tasks.
Same-Sex Effects (The Part Most Articles Skip)
Articles on male vs female pheromones almost always focus on cross-sex effects: what male compounds do to women, what female compounds do to men. The same-sex effects get less coverage and are no less real.
Male-on-male androstenone. Androstenone in male chemistry broadcasts dominance and presence cues to other men, and the effect isn’t necessarily friendly. Men exposed to androstenone in social-judgment tasks rate other men as more dominant and more aggressive. In male-on-male competitive contexts, androstenone-heavy chemistry can read as territorial or threatening rather than charismatic.
Female-on-female chemosignaling. The most-studied same-sex effect on the female side is the McClintock cycle-synchronization work from the 1970s, which suggested women living in close quarters synchronize menstrual cycles via volatile chemosignals. The effect has been controversial in replication, but the broader category of female-on-female chemosignaling has held up better. Women in stress contexts produce volatile compounds that affect other women’s stress responses, with implications for shared spaces like dorms, offices, and households.
Implications for product use. A man wearing androstenone-heavy chemistry into a male-dominated work environment is broadcasting different chemistry than the same product worn at a date or social gathering. The same compound produces different responses depending on who’s around to receive it. This is part of why pheromone product selection benefits from thinking about context as much as the wearer’s own sex.
Are Female Pheromones Stronger Than Male, Or Vice Versa?
This is one of the most common questions asked about male vs female pheromones, and the honest answer is that strength isn’t a single axis you can compare on.
Male and female compounds work at different concentrations on different receivers. Androstenone produces strong, fast effects on perceived presence in social-judgment contexts, sometimes at micrograms-per-application doses. Copulins produce slower, mood-and-hormonal effects on opposite-sex receivers at higher concentrations, while estratetraenol operates at sub-conscious-detection doses with effects measurable mostly in fMRI and hormonal assays rather than in everyday behavioral observation.
Asking whether female pheromones are stronger than male is roughly like asking whether espresso is stronger than wine. Both produce real effects, but on different receivers, at different doses, through different mechanisms. The useful question for a buyer is what kind of effect you’re after, not which side of the chemistry has more raw potency.
For practical purposes: male-targeted formulations focused on androstenone produce the most noticeable in-the-moment effects on perceived presence and dominance, while female-targeted formulations using copulins and estratetraenol produce subtler but still measurable effects on opposite-sex mood and attention. Each does what it does. Neither beats the other on a universal scale.
What This Means For Pheromone Product Selection
For most buyers, the practical question is which formulation to use given what they want to happen. The decision starts with intent, not with the wearer’s own sex.
Most commercial pheromone products are sex-targeted because the most predictable effects come from heterosexual cross-sex use, but the underlying chemistry is more flexible than the labels suggest.
For men aiming to affect women. Male-targeted formulations leaning on androstadienone, androsterone, and balanced doses of androstenone are the standard, with androstenone providing the dominance and presence note, androsterone softening it, and androstadienone supplying the mood and arousal effect documented in the Wyart and Jacob/McClintock work. The best pheromones for men page covers current top picks at this layer.
For women aiming to affect men. Female-targeted formulations leaning on copulins (sometimes androsterone supporting, since it carries the same pleasant musk in female chemistry) are the standard. Estratetraenol is occasionally added but its effects are subtler and harder to perceive directly. The best pheromones for women page covers the current female-targeted picks.
For same-sex social effects. Same-sex contexts (a man wanting to project presence among other men, a woman wanting to feel grounded in a female-heavy environment) often benefit from products their own-sex formulators have tuned. Andro-heavy male-targeted blends work for male-on-male contexts; copulin-leaning female products less so for female-on-female unless the goal is calming rather than activating.
The choice isn’t strictly bound to the wearer’s sex. A woman wearing an androstenone-leaning product to project presence in a male-heavy work environment is making a calibrated choice based on intent. A man wearing a small dose of a female-targeted product to soften his typical chemistry profile in close-relationship settings is making a similar choice. Both work, neither is the standard recommendation, and both reward wearers who understand what each compound family is doing.
The Bottom Line
Male and female pheromones differ in their dominant compound profiles, the receivers they primarily affect, and the behavioral signature each produces. They aren’t strictly binary categories; both sexes produce both compound families at different concentrations, and the labels point at dominant patterns rather than absolute differences.
Male pheromones are testosterone-derived steroids: androstenone, androstadienone, and androsterone. They produce the strongest effects on women through cortisol shifts, mood changes, and physiological arousal, with male-on-male effects centered on perceived dominance and presence.
Female pheromones are estrogen-derived steroids and copulins: estratetraenol from the steroid side, copulins from the vaginal-volatile side. They produce effects on men through hormonal shifts and brain-region activation, with cycle-related variation in copulin output making the female-side chemistry time-sensitive.
Cross-sex effects are the most-studied piece, but same-sex effects exist and shape how products perform in real-world contexts. A formulation worn into a same-sex environment broadcasts different chemistry than the same product worn into a mixed-sex one.
For pheromone product selection, the decision starts with intent rather than with the wearer’s sex. Male-targeted and female-targeted formulations exist because the cross-sex effects are most predictable, but informed wearers can use either family for context-specific outcomes.
The practical takeaway: the male/female pheromone distinction is real at the chemistry layer, fuzzier at the body-production layer, and most useful as a guide for matching product to intended effect rather than to the wearer’s own biology.
