Dear Dr, My son aged 38 and his wife have been trying to have a baby for six months now.  He has had some health problems in the last few years, including pituitary adenoma, which has been successfully treated with medication and now has been diagnosed with Hashimoto's disease.  Could this be affecting fertility.  I am very worried about this as I am sure they are but don't want to question them too much about it.

Summarized question: Does Hashimoto's disease affect infertility?
