Reproductive
c. 1800 BCE — Kahun Gynecological Papyrus, ancient Egypt
Endometriosis was a condition whose historical recognition unfolded slowly over centuries, with early physicians attributing its hallmarks to uterine displacement, inflammation, or moral failing rather than a distinct pathological process. It was not until the late nineteenth and early twentieth centuries that surgeons and anatomists began assembling a coherent picture of tissue growing outside the uterine cavity. The naming and systematic study of the condition transformed it from a vague cluster of complaints into a recognized gynecological entity.
Historical Narrative
Ancient Egyptian medical papyri, including the Kahun Gynecological Papyrus dating to roughly 1800 BCE, recorded descriptions of painful pelvic complaints in women that some later historians have speculatively associated with what would eventually be called endometriosis. Egyptian healers attributed such suffering to a wandering or agitated uterus, a concept that persisted through Greek and Roman medicine. Hippocratic writers in the fifth and fourth centuries BCE described the uterus as a mobile organ capable of causing widespread bodily disruption when it moved from its proper position, and painful menstruation was often folded into this explanatory framework. Treatment in antiquity centered on fumigation of the vaginal canal, aromatic pessaries, and measures intended to coax the displaced organ back into position.
Galen of Pergamon, working in the second century CE, elaborated the humoral interpretation of uterine disease, arguing that retained or corrupted menstrual blood produced dangerous accumulations. His framework dominated European medical thought through the medieval period, during which monastic healers and later university physicians continued to frame painful female complaints in terms of humoral imbalance, demonic influence, or insufficient sexual activity. Medieval Arabic physicians, including Ibn Sina, whose Canon of Medicine became a standard reference across both Islamic and European institutions, offered detailed accounts of uterine inflammation but lacked the anatomical vocabulary to distinguish endometriosis from other pelvic pathologies.
The Renaissance brought renewed interest in dissection and anatomical precision. Andreas Vesalius and his contemporaries corrected many Galenic errors regarding reproductive anatomy, yet endometriosis as a discrete entity still eluded description because internal tissue implants were rarely interpreted as anything other than incidental scarring or inflammatory residue. Seventeenth-century pathologists occasionally documented adhesions and unusual pelvic findings in postmortem examinations without grasping their significance.
A more recognizable clinical picture began to emerge in the nineteenth century. The German physician Carl von Rokitansky, conducting meticulous postmortem examinations in Vienna during the 1860s, described lesions on the ovaries and pelvic peritoneum that contained glandular structures resembling the uterine lining. His observations, published in detailed pathological atlases, were foundational, though their full implications were not immediately appreciated. Around the same period, the American surgeon Ephraim McDowell had already demonstrated that ovarian surgery was survivable, opening a pathway for future exploratory procedures.
The early twentieth century produced the most decisive conceptual breakthrough. John Albertson Sampson, a gynecologist practicing in Albany, New York, published a series of landmark papers during the 1920s in which he proposed that menstrual tissue traveled backward through the fallopian tubes and implanted on pelvic surfaces, a theory he called retrograde menstruation. Sampson also coined the term endometriosis in 1927, crystallizing decades of fragmented observations into a named and theorized disease. His transplantation hypothesis proved enormously influential, though rival theories invoking metaplasia of peritoneal cells were simultaneously proposed by researchers including Robert Meyer in Germany.
By the mid-twentieth century, surgical exploration of the pelvis had become the primary means by which physicians confirmed the condition's presence, and medical journals accumulated case series describing the varied patterns of implantation Sampson and others had predicted. The condition's long journey from unnamed complaint to defined pathology reflected broader transformations in pathological anatomy, surgical capability, and the professional standing of gynecology as a medical discipline.
