RESUMO
The effect of male axillary extract on the length and regularity of the menstrual cycle in women was studied in a long-term experiment (9 months). The male secret extract had no statistically significant influence on the menstrual cycle duration in the reproductive-age women (21-45 years) with normal (26-32 days) and regular cycles or in women with abnormally short (<26 days) cycles. In the group of the reproductive-age women with irregular and abnormally long (>32 days) cycles, as well as in the group of the premenopauseage women (46-51 years) with irregular cycles, the secret extract caused a significant shortening of the menstrual cycle as compared to the control. The effect was preserved for at least two months after the exposure completed.

The sensitivity to androstenone and possible factors, determining the sensitivity were investigated for the large sample of inhabitants of central Russia (n = 860). Specific anosmia was detected in 48.8% of subjects. Women were more sensitive to androstenone than men. The proportion of men, but not women perceiving the smell of androstenone as a strong one in the concentration used decreased with age. Smoking, blood group, or ethnicity had no significant effect on the expression of specific anosmia and the perception of androstenone odor intensity.
