The 22 Republicans who opposed the measure represented a cross-section of ideologies and had a variety of reasons for objecting. For instance Representative Bill Thomas, Republican of California and chairman of the Ways and Means Committee, said he objected because of an unexpected acceleration in the timetable for the federal government to stop Medicare and Medicaid reimbursement for drugs that treat sexual impotence.
Joking aside, I think Bill Thomas is exactly right. It's entirely appropriate for such programs to cover reproductive health issues including, but not limited to, impotency issues. Such issues include birth control, abortion, prenatal care, and general penis, vagina, testicle, ovary, prostate, and uterus maintenance programs.
