Abstract
Summary
Physiological luteolysis is the abrupt, dramatic, and irreversible decrease in progesterone secretion by the corpus luteum-bearing ovary. Neither an acute decrease in the number of luteal cells nor an acutely decreased rate of cellular proliferation could be demonstrated to occur in temporal synchrony with physiological luteolysis.
Financial support for this research was obtained from the National Science Foundation (GB-27118), the National Institute of Child Health and Human Development (HD-05633), and the Population Council. We are also indebted to Ms. Paula Herbst for typing the manuscripts and to Dr. John Jewell, Ayerst Laboratories, for donating the PMS and HCG.
