  ABSTRACT: Male sexual orientation has been proposed to have genetic components, but previously suggested candidate genes have all received negative results. The human sonic hedgehog (SHH) gene is located in the 7q36 region, which was linked to male sexual orientation in a previous genome-wide association study. SHH is known to play an important role in embryo patterning, and there is evidence connecting it to sexual orientation. In this study, we performed an association analysis of the SHH tag single nucleotide polymorphism rs9333613 in 361 subjects and 319 Chinese male controls. We find a significant difference in genotype and allele distribution between identified homosexuals and heterosexual control subjects, suggesting that the SHH gene could potentially be associated with male sexual orientation.

  ABSTRACT: PURPOSE: The objective of this study was to examine the interrelationships among individualism, collectivism, homosexuality-related stigma, social support, and condom use among Chinese homosexual men. METHODS: A cross-sectional study using the respondent-driven sampling approach was conducted among 351 participants in Shenzhen, China. Path analytic modeling was used to analyze the interrelationships. RESULTS: The results of path analytic modeling document the following statistically significant associations with regard to homosexuality: (1) higher levels of vertical collectivism were associated with higher levels of public stigma [β (standardized coefficient) = 0.12] and self stigma (β = 0.12); (2) higher levels of vertical individualism were associated with higher levels self stigma (β = 0.18); (3) higher levels of horizontal individualism were associated with higher levels of public stigma (β = 0.12); (4) higher levels of self stigma were associated with higher levels of social support from sexual partners (β = 0.12); and (5) lower levels of public stigma were associated with consistent condom use (β = -0.19). CONCLUSIONS: The findings enhance our understanding of how individualist and collectivist cultures influence the development of homosexuality-related stigma, which in turn may affect individuals' decisions to engage in HIV-protective practices and seek social support. Accordingly, the development of HIV interventions for homosexual men in China should take the characteristics of Chinese culture into consideration.
