概括
口服避孕药使用的变化可能对女性的性满意度有很小的影响. 一项元分析发现支持一致性假设的证据很少,这表明需要进一步的研究.
科学领域:
- 进化心理学 进化心理学
- 人类的性行为.
- 生殖健康 生殖健康
背景情况:
- 合并假说认为,女性激素水平的变化,特别是与口服避孕药的使用有关,影响交配心理和性满足感.
- 这种假设表明,与持续使用者相比,在遇到伴侣后改变使用激素避孕药的女性报告的性满意度较低.
- 调查一致性假设的先前研究已经产生了不一致的发现,需要进行全面的审查.
研究的目的:
- 进行现有研究的元分析,以评估一致性假设的有效性.
- 确定口服避孕药使用变化对女性在关系中的性满意度的整体影响.
主要方法:
- 对已发表的研究进行了元分析,研究了激素避孕药使用变化与性满意度之间的关系.
- 包括的研究都使用传统的元分析技术和强大的贝叶斯元分析进行了分析.
- 效果大小被分别用于受试者之间和受试者内部的研究设计.
主要成果:
- 对于参与者之间的设计 (13种效果大小),一致性和性满意度之间的聚合相关性在统计学上并不显著 (r = 0.04).
- 对主体间设计的贝叶斯分析适度偏好了零假设 (BF01 = 8.13),这表明对一致性假设的支持很少.
- 对于受试者内部设计 (4 个效果大小),聚合相关性在统计上是显著的 (r = 0.18),贝叶斯证据较弱,有利于一致性假说 (BF10 = 1.55).
- 在所有分析中,一致性效应的大小始终很小.
结论:
- 分析表明,口服避孕药使用的变化对女性平均性满意度的影响很小,但可能不大.
- 虽然在对象内部分析中观察到具有统计学意义的效应,但总体证据仍然不确定,个人经验可能有所不同.
- 建议进行进一步的研究,特别是随机对照试验,以最终解决与一致性假说相关的问题.

What do you think is the single most influential factor in determining with whom you become friends and whom you form romantic relationships? You might be surprised to learn that the answer is simple: the people with whom you have the most contact. This most important factor is proximity. You are more likely to be friends with people you have regular contact with. For example, there are decades of research that shows that you are more likely to become friends with people who live in your dorm,...

01:22Hormonal Regulation of the Menstrual Cycle
249
The ovarian cycle regulates endometrial changes throughout a single menstrual cycle via the coordinated action of gonadotrophin-releasing hormone (GnRH) and gonadotrophins.
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH...

01:30Hormonal Control of the Ovarian Cycle
371
The ovarian cycle is meticulously regulated by the hypothalamic-pituitary-gonadal axis. This cycle orchestrates the release of a mature oocyte, essential for reproduction.
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle. At puberty, GnRH secretion increases in both frequency and...

01:26Assessment of the Mouth
121
A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.

While variables are sometimes correlated because one does cause the other, it could also be that some other factor, a confounding variable, is actually causing the systematic movement in our variables of interest. For instance, as sales in ice cream increase, so does the overall rate of crime. Is it possible that indulging in your favorite flavor of ice cream could send you on a crime spree? Or, after committing crime do you think you might decide to treat yourself to a cone?

36.5K
The chi-square test is a statistical hypothesis test. It is used to check whether there is a significant difference between an expected value and an observed value. In the context of genetics, it enables us to either accept or reject a hypothesis, based on how much the observed values deviate from the expected values.
The chi-square test was developed by Pearson in 1990.
The first step of performing a Chi-square analysis is to establish a null hypothesis, which assumes that there is no real...
