First legislator: Medical research is predominantly done on groups of patients that include only men. For example, the effects of coffee drinking on health are evaluated only for men, and studies are lacking on hormone treatments for older women. Government-sponsored medical research should be required to include studies of women. Second legislator: Considerations of male / female balance such as this are inappropriate with respect to research; they have no place in science.
The statement 'Restriction to males of the patient base on which data are collected results in inadequate science' most directly counters the second legislator's objection.
