Abstract
Measurements of the growth rates of fetal endometrium, myometrium, and the fetal ovary between 13 to 36 weeks of gestation have been recorded. The relationship of the measurements to the age of the fetuses are presented on the basis of a linear regression analysis. It is concluded that the rates of growth are linear for the fetal uterus as well as the fetal ovary.
The size of the ovary at term and that of the newborn and older child have been studied by various authors (1, 2, 3). It appears that a study of the thickness of the endometrium and myometrium and the size of the ovary during different stages of intrauterine life has not so far been carried out. The present work was designed to study the growth rates of the uterus and ovary. The application of a statistical method can be used to predict the size of the ovary and the thickness of the endometrium and myometrium at any age of the fetus.
