All,
So a friend of mine is planning a family and haven’t gotten pregnant yet. Her gynac said they it may happen right away or may take even a year to conceive. Well, i don’t really understand this.
If a fertile man and woman are having frequent sex, what really leads to not getting pregnant?
In: Biology
There are a lot of steps internally to get from “sex” to “viable pregnancy”, and any of these steps can fail.
1) sperm and egg are not in the same place at the same time. Maybe that batch of sperm isn’t great, or it’s the wrong time of the month, or things just don’t align.
2) the egg gets fertilized, great! Now it has to implant into the uterine, and that can go wrong.
3) The implantation goes well, but the fertilized egg isn’t viable for whatever reason, so the zygote stops developing and is flushed with the woman’s next period.
You have to get past all 3 hurdles there before a pregnancy can really get going, and all of those are strictly luck-based.
