Normally ovulation is estimated to occur 14 days beforethe first day of the succeeding cycle. After ovulation, ovum waits fertilisation not more than 24hours. If not fetilised, it degenerates in the fallopian tube without leaving any trace of it.
Not all ovulated eggs end up in the peritoneal cavity due to the presence of the fimbriae in the fallopian tubes. The fimbriae help in capturing the egg released from the ovary and guide it into the fallopian tube for fertilization. If the egg is not captured by the fimbriae, it may not reach the peritoneal cavity.
The human ovum can remain viable for about 48 hours. And sperm about 24 hours.
Fertilization occurs when a sperm cell successfully penetrates and merges with an egg cell, typically within the fallopian tubes of the female reproductive system. This event usually takes place shortly after ovulation, when an egg is released from the ovary and is viable for fertilization for about 12 to 24 hours. Once fertilization occurs, it leads to the formation of a zygote, which will begin the process of cell division and eventually implant into the uterine lining.
An egg moves from the ovary to the uterus, through the Fallopian tubes.
Adult human females are born with all the egg cells they will ever have, which typically number around 1 to 2 million at birth. By puberty, this number decreases to about 300,000 to 400,000. Throughout a woman's reproductive life, only about 400 to 500 of these egg cells will mature and be ovulated. By menopause, the majority of egg cells are no longer viable.
The ovulated egg is stopped at metaphase II of meiosis. At this stage, the egg is arrested until fertilization occurs.
Within five days after ejaculation, sperm will typically survive in the female reproductive tract, awaiting fertilization of the egg. The released egg will be viable for fertilization for about 12-24 hours after ovulation. If fertilization does not occur, the egg will be reabsorbed by the body.

The fimbriae help in capturing the egg released from the ovary and guide it into the fallopian tube for fertilization.

From the moment of the fertilization of the egg by the sperm the new baby is alive. However at this stage it is not viable (it can not develop outside the mothers womb).

Once the egg is fertilized it remains fertilized until the egg is eaten, incubated or goes rotten and decays. It never goes back to being an unfertilized egg.
The human ovum can remain viable for about 48 hours. And sperm about 24 hours.
No. By the time a woman is due to menstruate the egg released earlier in her cycle is long dead - typically ovulation occurs 14 days before menstruation, and at most there will only be a viable egg for up to 48 hours after ovulation.
Fertilization of an egg happens before it is laid.
Conception is the moment of fertilization.
