  title = {A Short History of the Consideration of Sex Differences in Biomedical Research — Lessons for the In Vitro Community from Animal Models and Human Clinical Trials},
  abstract = {In recent decades, it has become clear that in many fields — such as drug development, particularly with regard to drug dosage and specific disease treatment — the sex of a patient must be taken into consideration, in view of the fact that male and female physiology and pathophysiology show many differences of practical concern. While, in the last decade or so, considerable efforts have been undertaken to consider the sex of the animals during the planning of experiments, this topic has just started to be acknowledged in in vitro studies. Cells in such studies seem mainly to be used according to their availability, without considering the sex of the original donor. Even when such information is available, experimental data are reported without overtly detailing this information. In recent years, the increasing complexity of in vitro models (e.g. stem cell-based, 3-D cultures, organoids, or organ-on-a-chip technologies) has contributed to systems that better resemble the human in vivo situation. However, the issue of the sex of the experimental organisms being used has not yet been properly taken up by the cell culture community. Thus, alongside the increasing complexity of multicell-type models, we now see in vitro models that incorporate cells from both male and female origin — this representing, in fact, a genetic chimaera. Here, we aim to discuss where we are currently, with respect to considering the sex of any animals or humans used in experiments, and we try to identify what is lacking in the cell culture field, in order to help facilitate change.},
