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 Hashimotos disease.  Could this be affecting fertility.  I am very worried about this as I am sure they are but dont want to question them too much about it.
yeah, it can be due to his thyroid problem. Tell him to go for sperm microscopic analysis. And IVF it will solve his problem easily. So do not worry. It is treatable. I wish you will become grandma soon of a small angel. Take care.
