Elster's rule provides a guide to the expected approximate pituitary gland height in relation to age 1. The rule follows an even-numbered pattern of 6, 8, 10, and 12. The height of pituitary gland is taken in sagittal MR 1:
6 mm pituitary gland height in infants and children
8 mm pituitary gland height in men and postmenopausal women
10 mm pituitary gland height in women of childbearing age
12 mm pituitary gland height in women in late pregnancy or in postpartum women
Some studies of pituitary height on MRIs in various healthy populations have had various results not necessarily in agreement with this rule 2,3.
