It is the physiological process by which two gametes (male and female) come together to form a zygote. It usually occurs after sexual intercourse, although in some special cases it can be produced in a laboratory (artificial fertilization). Fertilize, fertilize, beget, procreate, pregnant, reproduce.
Joining reproductive cells to spawn a new being. The origin is Latin of fecund, as, are, which is related to motherhood from a root that in Latin is interpreted as "to give, to feed, to introduce, . . . " and is part of femina ("who breastfeeds") among other words; adding the suffix -cundum that is used to indicate an abundance .
If we say that mate is the fusion of two gametes to accommodate the Zygote ( future be alive ) it cannot be said - because doctors are wrong in its usage - which a sperm fertilizes an egg, they both bind to that Union " fertilize " / produce a living being.It is as if I say that " dance to... " when actually " is danced with "Therefore, it cannot be said either that an egg is fertilized nor fertilized in vitro ( would be better to refer to this process of reproduction " fusion in vitro " ) because he is part of the active process which carries with it the action of both sperm fertilize. As fertilized it would be an egg as a sperm by the shape of traditional expression, and this makes sense: not for the fact that the reproduction of the human species is internal in nature may be associated who gamete with space that will develop, utero ( both integrated into the female space ). For not messing us: for example if we get together water with sugar and that Union call it FERTILIZATION, can let water peace to sugar nor that FECUNDÓ sugar to water. If a definition that has her looks for her, but not implying that one interacts on the other.I HOPE TO MAKE IT CLEAR
