I am not an md but I simply do not see how your dh's Lymphoma can be related to what he had to do for ivf.
I agree w/Helen.. I mean all he had to do was produce a sperm sample in a cup. In no way could him producing said sample give him cancer.
I'm so sorry to hear about you husband. I have to say though that there is no way invitro could do harm to your husband. Unless they did it differently 16 years ago than they do today. I really doubt it though. The men have the easy job of the invitro-and that is to provide a sample.
The good news about lymphoma, it usually has a great survival rate. Hopefully it's been caught in time.
I have to agree with the other ladies. I don't believe IVF caused your husband's condition. I pray that he will have a speedy recovery..
Question - Did he have to take any meds or go through a special procedures?
