Interesting discussion here!
ALF--I have read that there is new scientific debate over whether women are actually born with all of their eggs. I think the science is unclear on this, but it's not my field of expertise! See this article for an overview of some of the findings that threw this into question.
Either way, I take your point that egg maturation probably occurs on a longer time scale than the 2WW. However, implantation occurs at 7-10 days PO, so that is before HPTs are reliable. I would imagine that whatever the mother does or consumes around the time of implantation could affect the fetus. So I could see that as a potential mechanism for the finding in kar's study.
At any rate, my own philosophy is somewhere in between. I won't drink heavily or casually in the 2ww, but I will have a small drink of wine or beer for a special occasion.
Kar--I've read that downhill skiing is on the very short list of sports that you shouldn't do at any point during pregnancy (also: horseback riding, scuba diving), due to the risk of serious injury and hard falls. (This is per recommendation of the American College of Obstetricians and Gynecologists.) So I will switch to cross country and snowshoeing if the need arises. I see your point that the risks are probably greater later in pregnancy, but after my last loss I feel firmly that following the "rules" will be helpful in knowing that I am at least controlling the factors that I can, if I do indeed get a BFP.
keane--yes indeed! any reputable fertility clinic will not progress with fertility treatments without testing both partners! But TTC can be a complicated journey even without fertility issues, and it is the woman's body that regulates timing, so we end up with much of the responsibility to figure those thigns out.
EDITED TO ADD: Here is a link to the ACOG recommendations on exercise during pregnancy. I was surprised to read that there was a longer list of activities they recommended against than I was previously aware of.
In particular: no waterskiing, gymnastics, and contact sports (they specify hockey, basketball (!), and soccer (!)).
