Overall reproductive toxicity
- Reproductive effects observed:
- no
Applicant's summary and conclusion
- Conclusions:
- It was concluded from this study that administration of ABA-HCl to male and female rats had no adverse effect on the reproductive up to a dose of 1000 mg/kg bodyweight.
- Executive summary:
One generation Reproduction Toxicity Study in Rats
Mortality
No test substance related mortality occurred in this test study
Animal observation
The general condition of the parental animals was unaffected by treatment.
Bodyweights and food consumption
There were no significant differences in the body weights and in the food consumption.
Reproductive performance
Mating performance, fertility, gestation length and parturition were unaffected by treatment.
Significant higher post-implantation survival indices in all dosed groups compared to the control group were considered incidentally and not test substance related.
Viability of offspring was not affected by treatment. Statistically significant lower live birth and viability indices in the lowest dosed group were considered incidentally and not test substance related.
Sex ratio and body weight development of offspring was unaffected by treatment.
The incidence of external findings in the pups was low. Anasarca (generalized oedema) and a small fissure of the abdominal wall at the navel was noted in one pup of the lowest dosed group. This malformation was assessed as being of spontaneous origin.
Necropsy and hystopahthology
No treatment related changes were found.
