Journal ArticleDOI
Cold shock damage is due to lipid phase transitions in cell membranes: A demonstration using sperm as a model
Erma Z. Drobnis,Lois M. Crowe,Trish Berger,Thomas J. Anchordoguy,James W. Overstreet,John H. Crowe +5 more
TL;DR: The lipid phase behavior was consistent with the temperature range over which cooling was damaging for pig and shrimp sperm, and the with the extent of damage produced in pig and human sperm, the first direct evidence that cold shock results from lipid phase transitions in cell membranes.
Journal ArticleDOI
Semen Quality in Relation to Biomarkers of Pesticide Exposure
Shanna H. Swan,Robin L. Kruse,Fan Liu,Dana B. Barr,Erma Z. Drobnis,J. Bruce Redmon,Christina Wang,Charlene Brazil,James W. Overstreet +8 more
TL;DR: In this paper, the authors reported reduced sperm concentration and motility in fertile men in a U.S. agrarian area (Columbia, MO) relative to men from urban centers (Minneapolis, MN; Los Angeles, CA; New York, NY).
Journal ArticleDOI
Factors regulating mammalian sperm migration through the female reproductive tract and oocyte vestments.
TL;DR: The kinematics and consequences of hyperactivated sperm motion are presented, with emphasis on objective characterization of such motion (as a biomarker), along with analysis of the mechanical advantage that such motion may confer on spermatozoa during egg-vestment interaction.
Journal ArticleDOI
Are environmental levels of bisphenol a associated with reproductive function in fertile men
Jaime Mendiola,Niels Jørgensen,Anna-Maria Andersson,Antonia M. Calafat,Xiaoyun Ye,J. Bruce Redmon,Erma Z. Drobnis,Christina Wang,Amy E.T. Sparks,Sally W. Thurston,Fan Liu,Shanna H. Swan +11 more
TL;DR: Results suggest that, in fertile men, exposure to low environmental levels of BPA may be associated with a modest reduction in markers of free testosterone, but any effects on reproductive function are likely to be small, and of uncertain clinical significance.
Journal ArticleDOI
Semen quality in fertile men in relation to psychosocial stress
Audra L. Gollenberg,Fan Liu,Charlene Brazil,Erma Z. Drobnis,David S. Guzick,James W. Overstreet,James B. Redmon,Amy E.T. Sparks,Christina Wang,Shanna H. Swan +9 more
TL;DR: The results suggest that stressful life events may be associated with decreased semen quality in fertile men and the experience of psychosocial stress may be a modifiable factor in the development of idiopathic infertility.
