Body and organ weight: At the time of termination, body weight and weight of the following organs of all adult animals will be determined:
uterus (including cervix), testes, epididymides, prostate, seminal vesicles with coagulating glands, brain, heart, kidneys, liver, spleen and thymus, adrenals, ovaries, thyroids with parathyroids. Testes and epididymides will be weighed individually. Individual and/or paired absolute organ weight will be reported for each animal and adjusted for the body and brain weights. Paired organ weights as ap plicable will be summarised. Relative organ weight (to body and brain weight) will be calculated and reported. - Oestrous cyclicity (parental animals):
- - Number of pairings
- Number of pregnant females
- Number of sperm positive, but non-pregnant females
- Number of non mated females
- Duration of pregnancy (days)
- Number of Corpora lutea / dams
- Number of implantations / dams
- Number of dams with live pups Day 0 and 4
- * Pre-implantation mortality
- * Intrauterine mortality
- * Total mortality (intra and extra uterine mortality)
Detailed histological examination of the ovaries will cover the follicular, luteal, and interstitial compartments of the ovary, as well as the epithelial capsule and ovarian stroma. - Sperm parameters (parental animals):
- - Number of pairings
- Number of fertile pairings
- Number of infertile males
Special attention will be paid to evaluation of the stages of spermatogenesis in the male gonads and histopathology of interstitial testicular cell structure. - Litter observations:
- Females will be allowed to litter and rear their offspring. Delivery process will be observed as carefully as possible. Dams will be observed to record whether they form a nest from the bedding material and cover their new-borns or not. The efficiency of suckling will be observed by the presence of milk in the pups' stomach. Each litter will be examined as soon as possible after delivery to establish the number and sex of pups, stillbirths, live births, runts (pups that are significantly smaller than normal pups), the presence of gross abnormalities and any abnormal behaviour of the offspring. Live pups will be counted, sexed, weighed individually within 24 hours of parturition (ex. Day 0 or 1 post-partum, PND0 or 1) and on PND4, with accuracy of 0.01g. All the litters will be checked and recorded daily for the number of viable and dead pups. The pups found dead and intact (not cannibalized) will be subjected to necropsy with macroscopic examination and the cause of death will be identified if possible.
- Postmortem examinations (parental animals):
- Gross necropsy will be performed on each animal. Terminally (one day after the last treatment), animals will be sacrificed under anaesthesia by exsanguination; anaesthetic product may be diluted for pups’ euthanasia as required.
For the adult animals, detailed histological examination will be performed as follows:
• on the selected list of retained organs in the Control and High dose groups (selected 5 animals/sex/group),
• any animals found dead or euthanized pre-terminally during the study in all groups
• all macroscopic findings (abnormalities), except of minor order from all animals
• on the retained reproductive organs (testes, epididymides, prostate gland, seminal vesicles with coagulation gland for males and uterus, cervix, ovary, oviduct and vagina for females) of all animals of the Control and High dose groups and of all males that failed to sire and all females that failed to deliver healthy pups - Postmortem examinations (offspring):
- - Mean pup body weight (per pup within the group and per litter) on PND 0 and 4
- Mean pup body weight gain (per litter) between postnatal Days 0-4
The pups found dead and intact (not cannibalized) will be subjected to necropsy with macroscopic examination and the cause of death will be identified if possible. All observed abnormalities will be recorded. - Statistics:
- Data is collected using software PROVANTIS v.9. Statistical analysis is performed with the program package SPSS PC+4.0 (SPSS Hungary Kft, Budapest) or SAS v9.2 (when using Provantis).
In case of the SPSS PC+4.0 program package, the heterogeneity of variance between groups will be checked by Bartlett's test. Where no significant heterogeneity is detected, a one-way analysis of vari ance (ANOVA) is carried out. If the obtained result is significant, then Duncan's Multiple Range test is used to assess the significance of inter-group differences. Where significant heterogeneity is found, the normal distribution of data is examined by Kolmogorow-Smirnow test. In the case of non- normal distribution, the non-parametric method of Kruskal-Wallis One-Way analysis of variance is applied. If a positive result is detected, the inter-group comparisons are performed using Mann-Whitney U-test. The Chi-squared test will be used for non-continuous data.
In case of the SAS 9.2 software package (within the validated Provantis system) the following decision tree is applied automatically for statistical evaluation of continuous numeric data. The normality and heterogeneity of variance between groups will be checked by Shapiro-Wilk and Levene tests using the most appropriate data format (log- transformed when justified). Where both tests show no significant heterogeneity, an Anova / Ancova (one-way analysis of variance) test is carried out. If the obtained result is positive, Dunnett (Multiple Range) test is used to assess the significance of inter- group differences; identifying differences of <0.05 or <0.01 as appropriate. - Reproductive indices:

Additional information
In a repeated dose oral toxicity and reproductive toxicity screening study in the Wistar rat for 28 days according to the OECD 422 method, no significant reproductive toxicity was observed. There was no evidence of developmental toxicity in the offspring of this study. The NOAEL for reproduction is greater than the highest dose tested, 1000 mg/kg bw/day.
Mode of Action Analysis / Human Relevance Framework
Not applicable
Justification for classification or non-classification
In a repeated oral (gavage) dose toxicity and reproductive toxicity screening study in the rat for 28 days according to the OECD 422 method, no significant reproductive/developmental toxicity was observed. The NOAEL for reproduction is higher than the highest dose tested, 1000 mg/kg bw/day. The criteria for Regulation EC No. 1272/2008 for classification for reproductive toxicity are not met. The substance is not classified.
