Any other information on results incl. tables
No mortality occurred in the control or any of the dose groups during the treatment period of this study.
At 250 and 750 mg/kg/day, signs of discomfort such as pushing the head through the bedding material and salivation were observed throughout the study in males and females. Occasionally, piloerection, nasal discharge and eye closure were also observed.
Food consumption and body weight and body weight gain were not affected by the treatment with the test item.
Gross pathological examination of male and females at scheduled necropsy did not revealed any treatment-related findings.
Absolute and relative weight of uterus, ovaries, testis, epididymides and prostate were not affected by the treatment with the test item.
The histopathologic examination of male and female reproductive organs did not indicate any test item-related changes. Two females of the control group, one female treated at 100 mg/kg/day, two females treated at 250 mg/kg/day and one female treated at 750 mg/kg/day were found not to be pregnant at terminal sacrifice. As there was no dose relationship, this was not considered to be treatment-related.
The litter weight was not affected by the treatment with the test item either at birth or on postnatal day 4.
No treatment related effect was observed on the total number of pups born per litter, and on the sex ratio. No external findings and no gross abnormalities were observed in pups at necropsy.
Fertility, delivery and viability indexes were similar within the group and were not indicative of any effect of the test item. Precoital interval and duration of the gestation were also not affected by the treatment with the test item.
Mean number of corpora lutea and of implantation sites were not considered to be affected by the treatment with the test item. Incidence of pre- and post-implantation losses was also not affected by the treatment with the test item.
Litter size and sex ratio were not affected by the treatment with the test item either at birth or on PND 4. Gross necropsy of dead pups revealed no treatment-related findings.
Applicant's summary and conclusion
- Conclusions:
- The reproduction toxicity of the registration substance was investigated according to the Guideline OECD 421. The NOAEL of 750 mg/kg bw, corresponding to highest applied dose, was obtained for parental and for developmental effects.
- Executive summary:
The reproduction toxicity of the registration substance was investigated according to the Guideline OECD 421. The rats were treated via gavage at doses of 0, 100, 250, and 750 mg/kg bw.
At doses of 250 and 750 mg/kg bw signs of discomfort were observed but no severe clinical signs. No effects were observed in food consumption and body weight. Macroscopic and histopathologic parameters and evaluation of litter data did not induce any test item-related effect.
The NOAEL of 750 mg/kg bw was obtained for parental and for developmental effects.
