Drawing upon ethnographic research on menopause and intersexuality, this article points out the importance of awareness brought about by medical anthropology for developing better ways of medical treatment and diagnosis. Two findings of this literature are highlighted: 1) Human biology is far from having universal qualities as imagined in modern medicine, on the contrary it is subject to diff erentiation due to environmental, historical and cultural circumstances. This is why, it is important to think of biology in terms of its locality. 2) Modern medicine is not produced in a vacuum, rather it is a product of the interaction of multiple actors, technologies and bodies in a certain place and time. Therefore, doctors are always infl uenced by various prejudices and norms of the society that they are living in. Being aware of these points might contribute to the realization of a better medical training, more objective medical knowledge production and a better treatment process.
