Yes, I have been badly affected by my ICSI treatment, sleepless nights, bags under my eyes, a huge mummy tummy, greasy hair (but no stretch marks !) - and I wouldn't have it any other way. Running round after a very healthy and happy toddler has increased my reliance on pain killers and anti inflammatory drugs to deal with my arthritis...
I am unaware of any increase in my risks of contracting any diseases due to undergoing fertility treatment, but then again I could be hit by a bus - could you provide information / statistics on the problems your initial posting hinted at.
At the end of the day women who go through fertility treatment do so after years of struggle, often enduring stress and depression along the way - the decision to go through fertility treatment is not taken lightly and in the majority of cases, this is the only way we can realise our dreams of becoming Mothers.
We love our babies unconditionally, we live for today and plan for the future..... and that it what 'every parent' should do, regardless of how that baby was created. What will be will be.
