From the relevant toxicological studies, the SCCS regarded it reasonable to consider that a NOAEL for genistein aglycone is between 5 and 100 ppm. A recent report by the Nordic Council of Ministers (2020) has used 100 ppm as a NOAEL from the NCTR study for pregnant women (equivalent to 8.9 mg/kg bw). However, the same report used 100 ppm as a LOAEL for children (equivalent to 20 mg/kg bw) from a study by Li et al. (2014). In view of these studies, the SCCS considered it pragmatic to use 100 ppm as a LOAEL for the calculation of Margin of Safety (MoS) in the current assessment.","page":37,"pdf":"sccs_o_263.pdf","row_type":"noael_study","study_id":"sccs_o_263_noael_010"} |

From the relevant toxicological studies, the SCCS regarded it reasonable to consider that a NOAEL for genistein aglycone is between 5 and 100 ppm. A recent report by the Nordic Council of Ministers (2020) has used 100 ppm as a NOAEL from the NCTR study for pregnant women (equivalent to 8.9 mg/kg bw). However, the same report used 100 ppm as a LOAEL for children (equivalent to 20 mg/kg bw) from a study by Li et al. (2014). In view of these studies, the SCCS considered it pragmatic to use 100 ppm as a LOAEL for the calculation of Margin of Safety (MoS) in the current assessment.","page":37,"pdf":"sccs_o_263.pdf","row_type":"noael_study","study_id":"sccs_o_263_noael_010"} |

From the relevant toxicological studies, the SCCS regarded it reasonable to consider that a NOAEL for genistein aglycone is between 5 and 100 ppm. A recent report by the Nordic Council of Ministers (2020) has used 100 ppm as a NOAEL from the NCTR study for pregnant women (equivalent to 8.9 mg/kg bw). However, the same report used 100 ppm as a LOAEL for children (equivalent to 20 mg/kg bw) from a study by Li et al. (2014). In view of these studies, the SCCS considered it pragmatic to use 100 ppm as a LOAEL for the calculation of Margin of Safety (MoS) in the current assessment.","page":37,"pdf":"sccs_o_263.pdf","row_type":"noael_study","study_id":"sccs_o_263_noael_010"} |

From the relevant toxicological studies, the SCCS regarded it reasonable to consider that a NOAEL for genistein aglycone is between 5 and 100 ppm. A recent report by the Nordic Council of Ministers (2020) has used 100 ppm as a NOAEL from the NCTR study for pregnant women (equivalent to 8.9 mg/kg bw). However, the same report used 100 ppm as a LOAEL for children (equivalent to 20 mg/kg bw) from a study by Li et al. (2014). In view of these studies, the SCCS considered it pragmatic to use 100 ppm as a LOAEL for the calculation of Margin of Safety (MoS) in the current assessment.","page":37,"pdf":"sccs_o_263.pdf","row_type":"noael_study","study_id":"sccs_o_263_noael_010"} |

The time of preputial separation in males was not affected by administration of genistein. Testis weights were unaffected by either dose of genistein. The no observed adverse effect level (NOAEL) of genistein was considered to be between 4 and 40 mg/kg/day based on the hormonally induced functional changes at the higher dose due to the expected endocrine effects.
