TL;DR: Significant differences in fetal growth were found among the 4 groups and racial/ethnic-specific standards were found to improve the precision in evaluating fetal growth.

TL;DR: These findings are the first showing a relationship between WC and semen parameters in a sample of men without known infertility, and given the worldwide obesity epidemic, further study of the role of weight loss to improve semen parameters is warranted.

TL;DR: Several semen measures were significantly associated with TTP when modeled individually but not jointly and in the context of relevant couple-based covariates.

TL;DR: In this article, the authors used two sampling frameworks (i.e., fish/wildlife licence registry and a direct marketing database) for 16 targeted counties with presumed environmental exposures to persistent organochlorine chemicals to recruit 501 couples planning pregnancies for prospective longitudinal follow-up while trying to conceive and throughout pregnancy.

TL;DR: Stress significantly reduced the probability of conception each day during the fertile window, possibly exerting its effect through the sympathetic medullar pathway.
