About John A. Sampson

  • John Albertson Sampson (August 17, 1873–December 23, 1946) was a gynecologist who studied endometriosis. Sampson was born near Troy, New York and graduated from Johns Hopkins in 1899.
  • After completing his training in gynecology, he settled in Albany, New York.
  • He worked at the Albany Hospital, and later became Professor of Gynecology at Albany Medical College. While endometriotic cysts had been described before - notably by W.W.
  • Russell in 1898, it was Sampson who studied the disease systematically, described the clinical manifestations, and contributed to our understanding by proposing, in 1921, that endometriosis - a term he coined - is a process produced by the escape of menstrual debris including endometrial tissue that escapes retrograde through the fallopian tubes into the pelvis.
  • This then leads to secondary reactions of inflammation, repair, and scar formation.
  • His theory of "retrograde menstruation" explains the typical distribution of endometriosis in the pelvis and why women with cervical or vaginal obstruction have a high incidence of endometriosis, it does not, however, provide an answer why some women have endometriosis after hysterectomy or in distant organs.
  • Thus alternative theories have been developed, including the concept of endometriosis that starts in the pelvis de novo from stem cells.
  • Even today, these and other theories coexist, as the cause of endometriosis remains a subject of debate. He has the distinction of having an artery named after him, Sampson artery. Sampson died in Albany.
