A study has found differences in average testis size when comparing Europeans and Northeast Asians. Other studies have found differences in testosterone levels between Blacks, Whites and Northeast Asians. We sought to replicate and extend these findings in a dataset of 4,462 US soldiers (the Vietnam Experience Study). We find that those of Sub-Saharan African descent (Blacks, n = 525) average smaller testes than those of European descent (Whites, n = 3,654), d = 0.24, while Blacks average higher testosterone levels, d = 0.11. These patterns are not explained by differences in age, weight, or height. We discuss these findings in terms of evolutionary theory of sperm competition and mating systems. These differences are thought to relate to life history speed differences, especially regarding mating patterns. A more polygynous mating pattern is associated with smaller testes and high testosterone, whereas a more competitive/free mating pattern is associated with larger testes, helping with semen production and thus sperm competition. These findings are consistent with how individual level differences in ejaculate quality relate to life history speed.","PeriodicalId":35516,"journal":{"name":"Mankind Quarterly","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70543867","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A cross-sectional convenience sample of 381 college students responded to the Turkish version of the LLS. Cronbach's a was .95 for the long form LLS. Both Cronbach alpha and McDonald Omega values were .92 for the short form of LLS. Principal components analysis extracted one component labeled Love of Life for both forms. The short version of LLS contained four items, with a first principal component accounting for 80.15% of total variance. The long form of LLS correlated very highly with its short form. The sex difference for the long and short forms LLS total scores was not statistically significant. Age differences were found for the long form LLS total scores but not for the short form. The present results demonstrate the applicability of the Turkish version of the LLS to Turkish college students. © 2022 Ulster Institute for Social Research.
