Monkey fertility study: no impaired fertility at up to 25x the weekly human dose of 2 mg/kg
“A fertility study was conducted in female Cynomolgus monkeys at doses up to 25 times the weekly recommended human dose of 2 mg/kg of trastuzumab and has revealed no evidence of impaired fertility, as measured by menstrual cycle duration and female sex hormone levels.”
