Early life conditions, reproductive and sexuality-related life history outcomes among human males: A systematic review and meta-analysis

摘要: Abstract In order to investigate the association between early life conditions and reproductive sexuality-related history outcomes among men, we conducted a meta-analysis that compiled results of 198 articles. A total 331 effect sizes drawn from 573 samples were included. The revealed low family socioeconomic status was associated with sexual debut ( r =0.07), first birth =0.14), marriage =0.03). There no significant pubertal timing or number partners. Parental absence =−0.12), greater partners =−0.19), =−0.14), =−0.13). parental timing. Small body size before puberty delayed =−0.10). adult offspring, at size, siblings, older parents non-heterosexual orientation s=0.12, 0.03, 0.03 respectively). Factors such as sampling procedure, data collection method, age cut-off used measure structure change influenced some predictors (e.g., status) birth). findings are discussed in relation utility theory for understanding human male outcomes.
