probability of fertilization

[ladyspain]

hey ladies,

anyone know what the probability or statistics of all eggs "dropped" getting fertilized?
...just wondering...

Thanks!

I had the same dilemma earlier this week and I could not find a single number. It depends on a variety of factors - number of follicles, size of follicles, age of mother, fertility issue, method (IUI, IVF, natural), Estradiol, type of medication - Clomid vs. injectables, etc. My impression is that if using IUI, more follicles increase your chance of getting pg with at least 1 slightly - if 4+ then ~ 22%. If you get pg, it increases your chance of higher order multiples (3+) slightly as well, but the chance of higher order multiples is still small - < 5%. My RE told me that if we got pg, then the chance of getting pg with twins would be about 20%. Good luck! SSBD!

Normally, only one egg is released each cycle (unmedicated, natural cycles). On rare occasions 2 may release. Normal, fertile couples have about a 20% chance each cycle. That is why a couple is not considered "infertile" until 12 consecutive cycles of timed, planned intercouse.

Well it depends on how many eggs got dropped. I know with regular methods you only have 22-25% chance of getting pregnant each cycle. It doesn't seem like those are very good odds to me... I feel like it should be better odds than that but that is the truth of it.
