The way the anatomy of the female reproductive tract is prevents this. The only way it might happen is if the uterus is removed and the ovaries remain. The egg may end in the vagina. If the egg is excreted into the vagina and if fertilized, the embryo would be lost. If some how the embryo attaches to the wall of the uterus, it would also be lost. There is not enough room for it to grow.
there are many possible reasons for infertility. Genetic problems, damage to reproductive organs, stress, age, and many other factors can influence fertility/infertility. Note that in "first world countries" there is a growing problem with pseudo-female hormones leaching from plastic (like the bottles used for bottled water).
During the tetrad stage, the metaphase I of meiosis starts to happen. When this occurs, the diploid meiocyte divides twice.
ninjas happen
Natural selection is driven by differences in reproductive success between variants within the same population.
Tornadoes can happen in the tropics but they are more common in temperate latitudes.
When an animal is skinned, the animals is going to die. It is best to kill the animal before you try to skin it.
Yes it is if the genes from your African descent are strong enough it could happen
Legend of Success Joe happened in 1991.
The endometrium is the lining of the uterus.

Is when the RDP is success doing things for the community made things happen
No . It is entirely separate from your reproductive system.
No more reproducing, which means no more children.

Yes. Hurricanes usually happen form in the tropical oceans. Some times they can travel out of the tropics and make landfall in other areas besides the tropics. The link below has further information.
