Previous research has suggested that homosexual men's sibling sex ratio-the ratio of brothers to sisters collectively reported by a group of individuals-is elevated but only in samples of extremely feminine (e.g., transsexual) homosexual men. I conducted an additional test of a sibling sex ratio effect in a general sample of homosexual men (N = 237), and examined the correlation between sibling sex ratio and childhood gender identity. I found no significant effects. My discussion focuses on why little evidence of a relationship between sibling sex ratio and cross-gender behavior in childhood occurs within this general sample of homosexual men when samples selected for very feminine homosexual men have detected an elevated sibling sex ratio.
先前的研究表明，男同性恋者的手足性别比（即一组个体共同报告的兄弟与姐妹的比例）有所升高，但仅在极端女性化（如变性者）的男同性恋者样本中出现。我在一个男同性恋者的一般样本（N = 237）中对手足性别比效应进行了额外测试，并研究了手足性别比与童年性别认同之间的相关性。我没有发现显著影响。我的讨论聚焦于，在这个男同性恋者的一般样本中，为何在为极端女性化的男同性恋者所选取的样本已检测到升高的手足性别比的情况下，却几乎没有证据表明童年时期的手足性别比与跨性别行为之间存在关联。
