名詞

oosperm (複数形 oosperms)

1. (biology) The ovum, after fusion with the spermatozoon in impregnation.
   • 1880-1881, Francis Maitland Balfour, A Treatise on Comparative Embryology

     It is clear that the ovum after fertilization is an entirely different body to the ovum prior to that act , and unless the use of the same term for the two conditions of the ovum had become very familiar , a special term , such as oosperm , for the ovum after the fusion with the spermatozoom, would be very convenient.
