在一些灵长类动物中，雌性动物的肛门生殖器区域表现出夸张的肿胀。肿胀最严重的雌性动物会受到雄性动物最高水平的交配兴趣。我们的荟萃分析表明，肿胀的大小与生育能力密切相关。我们发现肿胀的大小也与身体状况呈正相关。结果支持分级信号和可靠指标假设。在一些旧大陆猴和猿类物种中，女性在整个卵巢周期中表现出肛门生殖器区域的尺寸变化过大。夸张的乳房通常在排卵期最大，并且据报道，肿胀的大小与女性质量呈正相关，支持夸张的乳房是女性生殖力和质量的真实信号的假设。然而，在一些研究中，肿胀大小和排卵时间之间的关系很弱，肿胀大小和女性质量之间的关系也没有一致的报道。在这里，我们整理了报告肿胀大小和估计排卵时间（N= 26）或肿胀大小和个体质量测量（N= 7）的经验研究，使用荟萃分析方法评估这些关系的强度。我们的分析证实，最大肿胀大小的时期与卵巢周期的最肥沃时期密切相关，并且大部分排卵发生在最大肿胀期间。一个小的，积极的影响大小也被发现的肿胀大小和身体状况之间的关系。与此相反，与年龄和社会地位的关系并不显着。因此，肿胀的大小可能是女性状况和生育期时间的信号。雄性可能会从根据肿胀大小分配交配努力中受益，而在雌性控制受到雄性交配策略损害的物种中，肿胀较大的雌性可能会从对交配的控制中受益。
HighlightsIn some primates, females exhibit exaggerated swellings of the anogenital region.Maximally swollen females receive the highest levels of mating interest from males.Our meta-analysis shows that swelling size is closely related to fertility.We show that swelling size is also positively correlated with body condition.The results support both the graded-signal and reliable-indicator hypotheses.In some species of Old World monkeys and apes, females exhibit exaggerated swellings of the anogenital region that vary in size across the ovarian cycle. Exaggerated swellings are typically largest around the time of ovulation, and swelling size has been reported to correlate positively with female quality, supporting the hypothesis that exaggerated swellings are honest signals of both female fecundity and quality. However, the relationship between swelling size and timing of ovulation is weak in some studies, and the relationship between swelling size and female quality has also not been consistently reported. Here, we collated empirical studies that have reported either swelling size and estimated timing of ovulation (N= 26) or swelling size and measures of individual quality (N= 7), to assess the strength of these relationships using meta-analytical methods. Our analyses confirmed that the period of maximal swelling size is closely associated with the most fertile period of the ovarian cycle and that a large proportion of ovulations occur during the maximal swelling period. A small, positive effect size was also found for the relationship between swelling size and body condition. In contrast, the relationships with age and social rank were not significant. Swelling size, therefore, potentially signals both female condition and timing of the fertile phase. Males are likely to benefit from allocating mating effort according to swelling size, while females with large swellings potentially benefit from exerting control over matings in species in which female control is compromised by male mating strategies.
