Researchers have been studying  for decades  the different ways that the birth control pill influences the structure of the brain, the function of the brain, and the way that it influences who we're attracted to romantically. Additionally, it can influence the quality of our relationships. It influences the stress response which is so far downstream from sex hormones that most people would never imagine that the pill would have an influence on these types of processes.

Dr. Sarah Hill's deep dive into decades of research compelled her to write a book and share the information with other women.
