What are the beliefs and practices related to menstruation and fertilization
Not the least
Your mother
You're pregnant or have hit the menopause. It can also be delayed by stress and such.
Birth control inhibits fertilization, not menstruation. Menstrual cycle will still continue.
For women, the uterine lining sheds, in the physiological term of menstruation. In rabbits, nothing happens. They just keep going in and out of heat until fertilization does occur. The same goes for cows and heifers.
Menstruation is a process of expulsion of un used egg in female pregnancy is egg got sperm attached and zygote formation fertilization resulting child birth
The answer to your question is puberty.
Menstruation is the shedding of tissue and blood from the lining of the womb that occurs at the beginning of menstrual cycle. Menstrual cycle is the series of changes a woman's body goes through to prepare for a pregnancy. Ovulation is a part of menstrual cycle when a mature egg is released from the ovary, pushed down the fallopian tube and is available to be fertilized. If you have intercourse during ovulation you can get pregnant. So, fertilization means that sperm has gotten to and entered the mature egg.
Menstruation is part of the woman's reproductive cycle. Through her menstrual cycle, she ovulates (or releases an egg from her ovaries). During this ovulation period, the egg awaits sperm from a males ejaculation which will then fertilize the females egg. If this fertilization process is successful, the female becomes pregnant. This process is necessary to keep up the human population.
Well, both fertilize the egg cell I hope you know that. I don't really know too much, but I hope I helped you at least a little bit.
If a woman is having her period, then she cannot be pregnant. Menstruation is a direct result of "failed fertilization", i.e. the egg (ovum) was not fertilized by a sperm cell. Therefore, women stop having their period when they conceive, since fertilization was successful and the production of ova (eggs) has ceased.
