reproductive capability

After taking the pills, a male mouse that already lost his reproductive capability was able to allow a female mouse to give birth to a nest of mice.(原本已无繁殖能力的雄性老鼠，在服用药物之后，居然能让母老鼠生出一窝小幼鼠。)

Indeed, some research groups have posited that the mother's finite reproductive capability is the result of accumulating these damaged and toxic compounds.(事实上，有研究小组断定过，母细胞的生殖能力之所以有限，是受毁损与有毒物质累积的结果。)

Haired heterozygous mice possess normal reproductive capability.(杂合子有毛小鼠的生育能力正常。)
