WTH - just wondering how you are. Praying some nice big follies growing well up there in Sydney.

CP - I am medically trained ( vet!) but still don't really get the whole DNA fragmentaion thing. Guess i haven't really looked into the SCSA test to see what is actually being measured. However, I sort of get what both your and Tam's FS are saying. DNA can't really be "changed" ie your DNA is your DNA- can't get around that. But, spem is made continuously and I assume in some men, for whatever reason, some sperm's DNA becomes damaged in the process, meaning some genetic info is missing etc. The menevit is supposedly aimed at helping reduce that potential damage during the sperm making phase.
Praying your next cycle is THE one - just takes one good egg and sperm!

Tam -best of luck with your upcoming cycle. Lets hope those healthy spermies do the trick!
As for the clomid dose, I would consider ringing you FS and asking about upping the dose.
Back in the early days of us TTC (seems like eons ago!), I did a few rounds of clomid. My FS started me on 25mg as well. I did ovulate but seemed very "weak" and certainly no BFP. The next cycle we did a monitored 50mg cycle which was much better and did result in pg although we sadly lost that little girl.
Peronally, I would want to go the 50mg but I do not know why you are taking it, other issues etc. Your FS is really the one to trust on that and I wouldn't up the dose without his ok.
