Other terms used to describe this phenomenon are fertilization, impregnation or fecundation.
Definition -Fertilization is the union of the ovum and a sepermatozoa.
Fertilization must occur fairly quickly after release of the ovum because it usually occurs in the outer third of a fallopian tube, the ampullar portion. The functional life span of aspermatozoa is about 48 hours / may be as long as 72 hours or longer. Therefore, sexual coitus during this time may result in fertilization /pregnancy.
