My husband amd I have been trying to get pregnant for 7 months now. He got a sperm analysis and it said 30 motile count sperm( not million just 30). He had Leukemia when he was 3 and had chemo. Also he has been smoking weed non stop for the last 4 years. The doctor does not know if it is the weed or the chemo. I think its the chemo. Has any men had cancer at young age and still able to get their wife pregnant naturally or IVF?
