In the quest to understand and manipulate human biology, scientists embarked on a series of controversial and ethically questionable experiments involving human hormones. In the early 20th century, researchers conducted experiments on individuals, often without their informed consent, administering various hormone preparations to study their effects. These experiments ranged from injecting hormones into prisoners to manipulating hormone levels in children to understand growth and development. The results of these experiments, while contributing to the advancement of medical knowledge, raised concerns about the boundaries of scientific research and the exploitation of vulnerable populations.
