[Thermal acclimatation in rats. I. Influence on reproductivity and fetal development]. / Adattamento termico nel ratto. 1) Influenza su riproduttività e sviluppo fetale.

Virgin female rats were kept in rooms where temperature was about 5 degrees C higher or lower than standard rearing temperature for two weeks before mating and during pregnancy. Acclimatation to changed environmental conditions caused reproductive alterations: ovulation increase; decrease of implanting blastocists and/or viable foetuses; developmental defects.
