Answer:
There can be lots of reasons when an egg is not fertilized and sometime these are couples of problem. Common reason egg is not fertilized:
- Age
- Ovulation
- Eggs production problem
- Fallopian tube blockage
It depends on the source of the egg.Most eggs you purchase are unfertilized. Occasionally a fertilized egg does get into the system. Usually there may be a spot of blood in the egg. That’s the beginning of a fetal
Every 28 days or so, one mature egg is released from the ovary. This is called ovulation. After the egg is released, it moves into the fallopian tube where it stays for about 24 hours. If the egg is not fertilized during that time, the eggdisintegrates (breaks down) and menstruation (your period) begins 2 weeks later.
If the egg is not fertilized during these days of ovulation when a mature egg is already present in the fallopian tube..the spe .(rm) (if has entered, through se (xual) means) gets inactivated once it enters the canal nd cannot find itself an ova i.e the ova
So now talkin about the female ova ..similarly if the ova is unable to find its sper. (m) partner again it comes down to the uterine level ..and the hormones act such that the uterus starts to form a blood mucosal lining internally preparing itself for the next menstrual cycle where all the contents along with egg is being passed down nd thrown out of the body through menstruation.
