my spouse and I are thinking of having children but are seriously concerned about some issues on the male side of his family. His half brother has aspergers tendencies and his son is diagnosed with aspergers. His full brother' son is autistic and is low on the spectrum. And my spouses youngest full brother also has aspergers tendencies. There is no other child in his extended family that has either autism or aspergers and none on my side of the family. Now is there reason to believe we have a high probability if we have a child it may be affected? And should we look into maybe doing sperm donation as he already has a low sperm count?
