Direct action of endocrine disrupting chemicals on human sperm.

چکیده
Synthetic endocrine disrupting chemicals (EDCs), omnipresent in food, household, and personal care products, have been implicated in adverse trends in human reproduction, including infertility and increasing demand for assisted reproduction. Here, we study the action of 96 ubiquitous EDCs on human sperm. We show that structurally diverse EDCs activate the sperm-specific CatSper channel and, thereby, evoke an intracellular Ca(2+) increase, a motility response, and acrosomal exocytosis. Moreover, EDCs desensitize sperm for physiological CatSper ligands and cooperate in low-dose mixtures to elevate Ca(2+) levels in sperm. We conclude that EDCs interfere with various sperm functions and, thereby, might impair human fertilization.

Background: There is an important evidence that prolonged exposure to several endocrine disrupting chemicals (EDCs). These are persistent materials with unique environmental properties such as intake of contaminated food, water and air, irrespective of proximity to industries, which are suspected to have endocrine disrupting activities.

متن کاملEDC IMPACT: Reduced sperm counts in rats exposed to human relevant mixtures of endocrine disrupters
Human semen quality is declining in many parts of the world, but the causes are ill defined. In rodents, impaired sperm production can be seen with early life exposure to certain endocrine-disrupting chemicals, but the effects of combined exposures are not properly investigated. In this study, we examined the effects of early exposure to the painkiller paracetamol and mixtures of human relevant...
