Epidemiological assessment of occupationally related, chemically induced sperm count suppression

Thomas H. Milby, +1 more
- 01 Feb 1980 - 
- Vol. 22, Iss: 2, pp 77-82
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.

Reproductive problems: fertility teratogenesis and mutagenesis.

TL;DR: This presentation focuses on the process rather than specific agents on the persons at risk, the types of exposures, the possible nature of the hazards, the factors which impinge on this risk, and the additional information required to make risk estimation more precise.
Journal Article

Iodine intake as a possible cause of discontinuous decline in sperm counts: a re-evaluation of historical and geographic variation in semen quality.

TL;DR: The synchronicity of the decline in mean sperm counts and the introduction of iodine supplements was analyzed statistically and it was shown that sperm counts began falling around 1965 in the United States, 40 years after iodine supplements were introduced.

Crimes against the environment : the state's responses to pesticide use in British Columbia

TL;DR: In this paper, the authors present an analysis of the British Columbia Pesticide Control Act (PCA), focusing on the political and social factors associated with the creation of the PCA in 1977 and amendments to the Act, at specific junctures.

A high proportion of double-headed and double-tailed sperm in semen of a human male: a case report

TL;DR: A patient whose semen contained 30% of sperm with double heads and double tails at various stages of attachment due to abnormal meiosis was presented, and it was postulated that abundance of the above‐noted type of sperm pathology in the human semen might not necessarily be associated with oligozoospermia or fertility impairment.

Environment and The Genitourinary Tract

TL;DR: A variety of environmental factors have been associated with conditions that affect the genitourinary system and host factors may contribute to the toxicity of these substances either by detoxifying them or by converting them to more active agents.
