TLDR
Exposure to DBCP, but not to ECH, was positively associated with detectable sperm count suppression and it is suggested that the key to identifying and assessing occupationally related sperm count suppressed lies in the proper classification and interpretation of group sperm count data.Citations

Journal ArticleDOI
Power considerations in studies of reproductive effects of vinyl chloride and some structural analogs.
TL;DR: In evaluating the studies of reproductive outcome in relation to vinyl chloride or analogs, it is considered what biologic model may have been tested and whether there was statistical power to detect moderate increases in risk and recommended sample sizes are set out.
Journal Article
The epidemiologic assessment of male reproductive hazard from occupational exposure to TDA and DNT.
TL;DR: Although both TDA and DNT are readily absorbed (percutaneous, inhalation, ingestion), they did not present detectable reproductive hazard to the workers.

Epidemiologic Studies of Male Factors in Infertility
Emmet J. Lamb,Sean Bennett +1 more
TL;DR: The various methods which epidemiologists can use to study this phenomenon including semen analysis to screen for exposure to toxicants and to establish regulatory levels for reproductive toxicants are considered and the effects of lifestyle (smoking alcohol consumption and the use of illegal drugs) on fertility are discussed.
Journal ArticleDOI
Mortality in an European cohort occupationally exposed to epichlorohydrin (ECH).
TL;DR: No evidence for an association between occupational exposure to ECH and the occurrence of malignant neoplasms in man is provided and current exposure levels are low, but exposure in the early days of production occasionally reached levels high enough to be irritating.

I. Effendy,Walter Krause +1 more
TL;DR: 93 consecutive patients attending the andrologic department for marital infertility were asked for possible environmental risk factors including traumata, heat, nois, smoking, radiation, micro waves, pesticides, and plastics.
