Neither emphysema nor reproductive disorders such as sterility are among those diseases which have been positively associated with exposure to Agent Orange. In fact, non-cancerous respiratory disorders and infertility/abnormal sperm parameters are conditions for which the VA has specifically found no association with exposure to herbicide agents. See 59 Fed.Reg. 341, 344-45 (Jan. 4, 1994). The veteran may, nonetheless, prevail in his claims if he can present evidence showing an actual causal connection between his herbicide exposure and his development of emphysema and/or sterility. See Combee v. Brown, 34 F.3d 1039 (Fed. Cir. 1994).
