Maybe it's more to do with mental health? Of all the homeless people I knew, a sizeable portion of them suffered from serious mental illnesses.

"After the tragedies caused by the use of thalidomide in pregnant women, the FDA issued “General Considerations for the Clinical Evaluation of Drugs” in 1977. This guidance document stated that women of child-bearing potential should be excluded from Phase 1 and early Phase 2 research, except if these studies were being conducted to test a drug for a life-threatening illness. If a drug appeared to have a favorable risk-benefit assessment, women could then be included in later Phase 2 and Phase 3 trials if animal teratogenicity and fertility studies were finished...In 1993, FDA reversed the 1977 guidance with another guidance document entitled Guidelines for the Study and Evaluation of Gender Differences in the Clinical Evaluation of Drugs."
