When sperm fuses with egg it is called fertilization .
In humans, fertilization occurs in the ampulla of the uterine tube. During fertilization the sperm and the egg become one and become what is called a zygote.
If it is outside the female body, it is called in vitro fertilization. If it occurs outside the uterus it is called an ectopic pregnancy.
The two types of fertilization are 1. Internal fertilization 2. External fertilization Internal fertilization takes place within the body of the female. External fertilization takes place outside the body of female. It takes place by layong eggs.
oviduct (fallopian tube) fertilization normally occurs here
In most amphibians, fertilization takes place externally instead of internally. To prevent the eggs from drying out, external fertilization occurs in water or another moist place.

Fertilization occurs in the oviduct of the female reproductive tract
In bryophytes, fertilization typically takes place in the archegonium, which is the female reproductive structure. The sperm swims through water to reach the egg inside the archegonium, where fertilization occurs.
Fertilization of the ovum typically occurs in the fallopian tube, not long after ovulation. The sperm meets the egg in the fallopian tube, and fertilization usually takes place there before the fertilized egg then travels to the uterus for implantation.
During the fourth week implantation of fetal development takes place. At this stage the fertilized egg is now called a blastocyst.
The fertilization of the egg most often takes place in one of the fallopian tubes. Fertilization typically occurs within 24 hours of the egg being released.
