At the end of the luteal phase, estradiol levels drop to their menstrual levels unless there is a pregnancy.

The four major naturally occurring estrogens in women are estrone (E1), estradiol (E2), estriol (E3), and estetrol (E4). Estradiol (E2) is the predominant estrogen during reproductive years both in terms of absolute serum levels as well as in terms of estrogenic activity.

A replication of this study using the same dosage and protocols measured estradiol levels of 2227 ± 1180 pg/mL for the whole group of women but found that estradiol levels between the normotensive and hypertensive groups were significantly different at 1790 ± 869 pg/mL and 2664 ± 1490 pg/mL, respectively.
