The study aimed at testing chronotype and gender differences in the time of day when humans feel the greatest need for sex and the time of day they actually undertake sexual activity. A Polish sample of 565 participants aged between 18 and 57 was tested. In females, regardless of chronotype, the greatest need for sex occurred between 18:00 and 24:00, but a secondary peak appeared only in morning types at 6:00-9:00. In males, the greatest need for sex occurred either in the morning or evening hours: in evening types at 9:00-12:00 and 18:00-3:00; in neither types at 6:00-9:00 and 18:00-24:00; in morning types at 6:00-12:00 and 18:00-24:00. Considering time of day when subjects were undertaking sexual activity most frequently, this appeared between 18:00 and 24:00 for all the participants, and prolonged until 3:00 at night in evening type males. Morningness preference was more strongly related to the timing of need for sex than to the timing of actual sexual activity (r = -0.275 vs. r = -0.174), while the timing of desire and the timing of sexual activity were positively, but moderately related (r = 0.320).
该研究旨在测试人类在一天中感觉最有性需求的时间以及实际进行性活动的时间上的昼夜节律类型和性别差异。对565名年龄在18至57岁之间的波兰参与者样本进行了测试。在女性中，无论昼夜节律类型如何，性需求最高的时段出现在18:00至24:00之间，但只有晨型女性在6:00 - 9:00出现了第二个高峰。在男性中，性需求最高的时段出现在上午或晚上：夜型男性在9:00 - 12:00和18:00 - 3:00；非晨非夜型男性在6:00 - 9:00和18:00 - 24:00；晨型男性在6:00 - 12:00和18:00 - 24:00。考虑到受试者进行性活动最频繁的时间段，所有参与者的这一时间段都出现在18:00至24:00之间，夜型男性则会延长至夜间3:00。晨型偏好与性需求时间的相关性比与实际性活动时间的相关性更强（r = -0.275对r = -0.174），而欲望时间和性活动时间呈正相关，但相关性中等（r = 0.320）。
