Substance P is a neuropeptide that has been identified in the ovary, fallopian tube, uterus, and vagina and in the hypothalamic-pituitary axis in both an animal model and human ovaries. We sought to determine if substance P is present in pe…

Our laboratory previously demonstrated that normal human endometrium contains hCG/human LH receptors. Since ectopic endometrial implants in endometriosis arise directly at least in part from uterine endometrium, we investigated whether the …

Peritoneal endometriotic implants and adjacent normal peritoneum from five patients were analyzed for prostaglandin (PG) release. Each tissue biopsy was incubated using medium 199 in triplicate at 37 degrees C for six hours, and PGF2 alpha …
