Objectives : this study was to access the effect of Hyeonggaeyeongyotang water extracts, a polyherbal formula has been used as folk medicine, on the fertility and early embryonic development of male and female Wistar rats when administered by oral gavage. Methods : In male rats, Hyeonggaeyeongyotang extract were dosed 4 weeks before pairing and 2 weeks after mating including the mating periods up to termination after necropsy of the majority of the females. In female rats, they were dosed 2 weeks before pairing, and from Day 0 to Day 7 of gestation. This study was conducted in accordance with the recommendations of the KFDA Guideline [2005-60] for Detection of Toxicity to Reproduction for Medicinal Products. Results: 1. No Hyeonggaeyeongyotang extract treatment-related changes on the clinical signs and mortalities, the Food consumptions, the Body weights and gains were demonstrated in all dosed levels tested in this study except for 500ml/kg-dosing male group in which a significant(p<0.05) increase of body gains was detected during day 0-7 after dosing. 2. No Hyeonggaeyeongyotang extract treatment-related changes on the pre-coital intervals, the estrus cycles, the mating index, conception rate and fertility index were demonstrated in all dosed levels tested in this study. 3. No Hyeonggaeyeongyotang extract treatment-related gross findings on reproductive organs, the weights of reproductive organs, histopathological findings on reproductive organs, the corpora lutea number, implantation site number, live fetus number, number of resorpted embryo and pre-and post-implatation loss were demonstrated in all dosed levels tested in this study. Conclusions : Base on the results, it is considered that the NOAEL (No-Observed-Adverse-Effect Level) for fertility and early embryonic development toxicity of Hyeonggaeyeongyotang extract was under 2000ml/kg/day in Wistar male and female rats because there no treatment-related changes on the fertility and early embryonic developmental index were demonstrated in all dosed levels tested.
