人类性唤起引起的变化具有生殖和娱乐功能。当前的性阶段模型（欲望、兴奋、性高潮和解决）几乎没有传达这种二元制的信息。三分之一的非临床女性缺乏自发性欲，表明 D 期需要分裂为 D1（欲望的自发内源激活）和 D2（在 E 期和期间由性兴奋激活的欲望）。通过在月经周期中监测 D1 的研究，试图将 D1 与生殖联系起来，结果发现 D1 在排卵前或排卵时出现峰值，但由于排卵时间识别不佳，其可靠性受到批评。性唤起会增强生殖器血流，导致神经源性漏出液的形成，润滑阴道，部分缓冲其酸度，并增加其氧张力，所有这些功能都增强精子的功能和存活。性高潮伴随阴道和子宫收缩而发生。后者被误解为促进精子快速运输以促进受精，但这种快速运输会导致无能力、无能力的精子在输卵管沉积。然而，阴道宫颈抬高会延迟精子的快速运输，并允许在抬高消退之前启动解凝和精子获能。精子从子宫颈到输卵管的最快运输发生在未性唤起的女性中，通过子宫/子宫内膜下平滑肌的蠕动。有一些证据表明，即使在性交后，这种情况也可能会减少一段时间，从而增加运输延迟。如果性唤起引起的许多变化没有得到充分表达，则可能会出现性功能障碍和生殖功能障碍。
Changes induced by human sexual arousal serve reproductive and recreational functions. The current sexual phase model (desire, excitation, orgasm, and resolution) conveys little about this duarchy. Lack of spontaneous sexual desire in a third of nonclinic females indicates that the D phase needs splitting into D1 (the spontaneous endogenous activation of desire) and D2 (desire activated by sexual excitation at and during the E phase). Attempts to link D1 with reproduction by studies monitoring it over the menstrual cycle revealed a D1 peak just before or at ovulation, but its reliability is criticized because of the poor identification of the time of ovulation. Sexual arousal initiates enhanced genital blood flow, leading to the formation of a neurogenic transudate, lubricating the vagina, partly buffering its acidity, and increasing its oxygen tension all features that enhance spermatozoal function and survival. Orgasm occurs with vaginal and uterine contractions. The latter have been misinterpreted as powering rapid sperm transport to facilitate fertilization, but such fast transport would lead to the tubal deposition of noncapacitated, incompetent spermatozoa. Vagino–cervico elevation, however, delays rapid sperm transport and allows the initiation of decoagulation and sperm capacitation before the elevation resolves. The fastest transport of spermatozoa from cervix to the fallopian tubes occurs in the nonaroused female by uterine/subendometrial smooth muscle peristalsis. There is some evidence that even this may be reduced for a time after coitus, adding to the transport delay. If a number of the changes induced by sexual arousal are inadequately expressed, sexual as well as reproductive dysfunctions could arise.
