Data are expressed as mean±SD.
^aFetus gender ratio=Number of male rats÷number of female rats.
^bPre-implantation loss (%)=(number of corpora lutea-number of implantation sites)÷number of corpora lutea x100%.
^cPost-implantation loss (%)=(number of implantation sitesnumber of live fetuses)÷number of implantation sites x100%.
^*Significantly different from the negative control group (p<0.05).
