6 Oct 2009DISCUSSION
Epidemiologic data from human populations and animal studies indicate that chronic exposure to N20 may result in impaired reproductive function and decreased fertility rates. The mechanism by which N20 might elicit reproductive toxicity is unclear. N20 may interfere with reproductive function at the level of the hypothalamus, pituitary, or reproductive tract. Our previous studies indicate [...]

5 Oct 2009Viability
Exposure to 60% N20 over a period of 24 hours did not affect viability of the GT1-7 cells. The total protein content of the cells was also not significantly different between air-exposed and N20-exposed cells. The effects of oxygen concentration (21% vs 35%) on cell viability and protein concentration over 36 hours were also evaluated [...]

However, a number of studies have associated chronic exposure to N20 with certain adverse effects, such as leukopenia, embryo toxicity, and fetal death. Exposure to N20 in operating rooms appears [...]
