This study did not demonstrate maternal toxicity and anti-implantation effect; however, there was reduction of fetal body mass, which might indicate possible embryofoetotoxicity.
Adverse fetal effects (increased resorptions and decreased fetal weight) were noted only at the very high parenteral doses that produced maternal toxicity.
The highest DEBT dose--a huge dose, far higher than the normal human dose--was associated with maternal toxicity (reduced body weight and food consumption) and lower birth weights in the offspring; there was no evidence of fetal toxicity or malformations, regardless of the dose used.
