It shouldn't matter right?! Please tell me it doesn't matter..... about to do 5th round of IVF, this time with donor sperm (all others with low quality after vasectomy DH's). I'm really exited at one level - had to bring forward my egg collection date as I was responding so well - 12 follicles each side - but I'm a bit concerned that feeling so under the cosh with this cold/sore throat might affect things. Anybody have experience of this?
