摘要

多产的生殖生物学家奈尔斯·牛顿(Niles Newton)描述了女性性反应和分娩之间在生理、心理和荷尔蒙方面的相似性。这种表型重叠表明了共同的机制,这使得Newton提出一个过程中的功能障碍可能会干扰另一个过程。目前很少有关于出生前女性性行为如何影响随后的分娩的研究。我们解决了这一知识差距,并扩展了牛顿的工作,提出性活动为女性提供了生理和心理上为分娩做准备的机会,我们称之为“分娩练习”。为了介绍和描述分娩框架的实践,我们详细回顾了女性生殖器-骨盆的显著反射,以及促进性快感和分娩的心理状态。这些生理和心理机制代表了性和生育之间的假定联系,这支持了我们的预测,即性活动为女性的生育做了准备。我们通过三个系统综述来证明分娩框架实践的效用,评估以下假设:(1)盆底干预联合改善性功能和分娩结果;(2)产前性活动和/或性功能的存在预示着分娩和出生的改善;(3)性功能障碍的存在会影响生育结果。我们的研究结果为这三个假设提供了显著的证据,尽管几乎没有数据将女性性高潮或性兴奋与分娩直接联系起来。我们描述了对分娩假说的进一步检验的具体想法,它的实际意义,以及性别-生育相互关系的相关性,以更广泛地为正在进行的关于女性性高潮和性行为的进化生物学辩论提供信息。分娩实践假说提供了一个有组织和可测试的框架,通过它来调查女性性行为对生育的潜在好处。

Practice for Parturition: Does Sexual Activity Improve Labor and Birth Outcomes?

Niles Newton, a prolific reproductive biologist, described physical, psychological, and hormonal similarities between female sexual response and childbirth. Such phenotypic overlap indicates shared mechanisms, which led Newton to suggest that dysfunction in one process could interfere with the other process. There currently exists very little research on how pre-birth female sexuality impacts subsequent parturition. We address this knowledge gap and extend Newton’s work by proposing that sexual activity provides opportunities for women to physically and psychologically prepare for childbirth, a process that we call “practice for parturition.” To introduce and describe the practice for parturition framework, we provide a detailed review of salient reflexes of the female genito-pelvis, as well as psychological states that facilitate both sexual pleasure and parturition. These physical and psychological mechanisms represent putative links between sex and birth that underpin our prediction that sexual activity provides birth preparation for women. We demonstrate the utility of the practice for parturition framework through three systematic reviews, evaluating the following hypotheses: (1) Pelvic floor interventions jointly improve sexual function and birth outcomes; (2) the presence of pre-birth sexual activity and/or sexual function predicts improved labor and birth; and (3) the presence of sexual dysfunction impairs birth outcomes. Results from our review provide notable evidence supporting the three hypotheses, although there are little to no data directly linking female orgasm or arousal with parturition. We describe specific ideas for further tests of the practice for parturition hypothesis, its practical implications, and the relevance of sex-birth interrelationships to informing ongoing debates concerning the evolutionary biology of female orgasm and sexuality more broadly. The practice for parturition hypothesis provides an organizing and testable framework through which to investigate potential benefits of female sexuality on birth.
