[quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous]OP here.  This is exactly what I mean.  For lack of a better word, is the 5% statistic for "normal" people or only known for people TTC using a RE?      [/quote]

No, it's based on the fact that your eggs are 42 yrs old.[/quote]

Please explain how figure of 5% follows from number 42. [/quote]

It's a figure based on the data that shows about 5% of the women who are trying to conceive at that age get pregnant and even less deliver.  It's simply the way it is.  Even in the best of circumstances, two 18 yr olds, there is only a 20% chance of conceiving each month.  It declines after 30 yrs old and even more sharply after 35 yrs old and take a nose dive after 41 yrs old.  We are born with our eggs, they age with us.  When reproductive endocrinologists quote you percentages, it's based on the SART data compiled from women in that age group conceiving and delivering a live baby.  [/quote]

I guess you haven't really followed the discussion. Nobody knows how many women are "trying to conceive" - all we have are births for women in a 40-44 age-group. The 5% figure is probably (though nobody here knows for sure) based on women who have trouble conceiving and decided to use IVF - not a random sample at all.

And please stop patronizing us with the spiel about aging eggs. Everybody on these forums knows those facts 50 times over.[/quote]
