When the female egg cell met with sperm
Privileged sites include the uterus, testes and anterior chamber of the eye. Immune tolerance is developed "before" puberty. Sperm develop in the testes during puberty and become immunogenic. A fetus develops in the uterus after puberty as well. They must be protected from the adaptive immune system in order to survive.
The father's sperm cell and the egg cell will typically meet and fertilize in the woman's fallopian tubes, which are located in her reproductive system. From there, the fertilized egg will travel to the uterus, where it may implant and develop into a pregnancy.
To get pregnant, sperm need to be ejaculated near the opening of the vagina. From there, they can swim through the cervix and into the uterus, where fertilization may occur if an egg is present.
In humans, sperm and egg meet in the Fallopian tubes. The egg continues to move to the uterus. If the egg was fertilized, it will stay in the uterus and grow.
No and no. Sperm doesn't fuse with other sperms.
An egg gets fertilized in the fallopian tube by a sperm, then it goes inside of the uterus, and inside the uterus it develops.
Frogs don't need have their offspring develop inside them. So if you were to dissect a frog you would not find the uterus because frogs release sperm and eggs to develop outside the body. Technically, the uterus is the outer shell of the egg...
The fetus is in the uterus and when pregnant there's a mucus plug closing the entrance to the uterus so semen or anything else can not enter when you are pregnant.
Into her uterus.
A period is the term used for the layers of skin to shed from the uterus. The uterus is where the egg will be implanted and cells divide to form a fetus. Every month (in most cases) a woman releases an egg from her ovaries and it travels down the fallopian tubes to the uterus. If the egg is not fertilized by sperm from a male, it will be shed along with the lining of the uterus. If the egg is fertilized, then it will implant itself into the lining of the uterus to develop into a fetus, thus causing the stop of a period during pregnancy.
No
In a human female eggs move from the ovaries where they are formed through the Fallopian tubes where they are fertilized if sperm are present to the uterus where they mature into an embryo and later into a fetus and eventually to a child.
The ovaries are connected to the fallopian tubes - where the egg and sperm would meet. The fallopian tubes are then in turn connected to the uterus - where a fetus would develop. The whole reproductive system is connected to the abdomen of the female body.

It develops in the uterus if it is nurtured by sperm.
