Conception
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.
