PSORHN takes its history two years ago when a couple of nurses became actively involved in the Reproductive Health Bill advocacy and campaign. These nurses recognized the need for an organized group to continue the advocacy and saw the need to specialize on sexual & reproductive health and rights (SRHR) going beyond maternal & child health.
This group of nurses launched an online campaign group known as RNs for RH which was largely operating in a social networking site known as Facebook. During the initial stages of conceptualizing for PSORHN, it took the name Reproductive Health Nurses Association of the Philippines (RHNAP) but later was changed to PSORHN since majority of the active founding members agreed to use of Society instead of Association.
