This study, following Camperio-Ciani, Corna, and Capiluppi [(2004), Proceedings of the Royal Society of London, Series B, Biological Sciences, 271, 2217-2221] aimed to examine the familial history of male homosexuality, and test the so-called "fertile female" hypothesis for this trait in a contemporary British sample. Using a comparative survey design, we found that white (comprising those of Anglo-European descent) and non-white (comprising ethnic "Blacks, "South Asians," "East Asians," "Hispanics," and "Others") homosexual men (n = 147) had a significant excess of maternal but not paternal line male homosexual relatives compared to heterosexual men (n = 155). We also found significantly elevated fecundity of maternal aunts of white homosexual men compared to white heterosexual men, whereas non-white heterosexual men showed elevated fecundities of almost every class of relative compared to non-white homosexual men. No significant excess of older brothers was found in homosexual compared to heterosexual men, irrespective of ethnic grouping. These data were discussed in relation to possible population-related factors in evolutionary explanations for human male homosexuality.
本研究遵循坎佩里奥 - 恰尼、科尔纳和卡皮卢皮[（2004年），《伦敦皇家学会学报，B辑：生物科学》，第271卷，2217 - 2221页]的研究方向，旨在调查男同性恋者的家族史，并在当代英国样本中检验针对该特征的所谓“生育力强的女性”假说。通过比较性调查设计，我们发现，与异性恋男性（n = 155）相比，白人（包括盎格鲁 - 欧洲血统者）和非白人（包括“黑人”“南亚人”“东亚人”“西班牙裔”及“其他”族裔）同性恋男性（n = 147）的母系男性同性恋亲属显著多于父系。我们还发现，与白人异性恋男性相比，白人同性恋男性的姨妈生育力显著更高，而与非白人同性恋男性相比，非白人异性恋男性几乎各类亲属的生育力都更高。无论种族分组如何，与异性恋男性相比，同性恋男性中未发现哥哥数量显著过多的情况。我们结合人类男性同性恋进化解释中可能与群体相关的因素对这些数据进行了讨论。
