Androstenone (5α-androst-16-en-3-one) and other androstenes, body odor components occurring in apocrine secretions, may play a role in human chemosignaling. We hypothesized that the odor of androstenone may gain hedonic value from sexual intercourse experiences via associative learning. Young adults (N = 397, 61.5% women, age 21-24 years, randomly sampled regarding sexual experience) rated the intensity and pleasantness of the odors of androstenone, cinnamon, chocolate, isovaleric acid, lemon, and turpentine. Among women who were able to perceive androstenone, the odor was rated as more pleasant (less unpleasant) by those who had had experienced sexual intercourse with at least one partner (n = 175) than by those who reported never having experienced intercourse (n = 12, p = .006). The difference was specific to women. The results suggest that, among women, sexual experience may modify the pleasantness of the odor of androstenone.
雄甾酮（5α-雄甾-16-烯-3-酮）和其他雄甾烯，存在于顶泌汗腺分泌物中的体味成分，可能在人类化学信号中发挥作用。我们假设，雄甾酮的气味可能通过联想学习从性交经历中获得快感价值。年轻成年人（N=397，女性占 61.5%，年龄 21-24 岁，关于性经验随机抽样）对雄甾酮、肉桂、巧克力、异戊酸、柠檬和松节油的气味强度和舒适度进行了评分。在能够感知到雄甾酮的女性中，那些有过至少一个性伴侣的女性（n=175）对雄甾酮气味的评价比从未有过性经验的女性（n=12，p=0.006）更为愉悦（不愉快）。这种差异是针对女性的。研究结果表明，在女性中，性经验可能会改变雄甾酮气味的舒适度。
