TL;DR: The growing number of reports demonstrating that common environmental contaminants and natural factors possess estrogenic activity presents the working hypothesis that the adverse trends in male reproductive health may be, at least in part, associated with exposure to estrogenic or other hormonally active environmental chemicals during fetal and childhood development.

TL;DR: The study suggests that the current WHO guidelines for normal semen quality should be used with caution, as some men with sperm counts above the lower limit of the normal range defined by WHO may in fact be subfertile.

TL;DR: Individuals without IHD but with low circulating IGF-I levels and high IGFBP-3 levels have significantly increased risk of developing IHD during a 15-year follow-up period, suggesting that IGF- I may be involved in the pathogenesis of IHD.

TL;DR: There was significant excess familial risk for cancer overall and for specific types of cancer, including prostate, melanoma, breast, ovary, and uterus, in this long-term follow-up study among Nordic twins.

TL;DR: This book studies and applies modern flexible regression models for survival data with a special focus on extensions of the Cox model and alternative models with the specific aim of describing time-varying effects of explanatory variables.
