Although many females do get pregnant with hypothyroidism
condition but ideally your TSH
levels should be normalised before you undertake IVF treatment.
There is no point going ahead with IVF with uncontrolled thyroid.
Ideally your TSH level should be around 2 at the time of going for your IVF.
So control your thyroid and then go for IVF treatment.
After all it is your money,why should you waste it.
