Effect of Perimenstrual Ovarian Steroid Supplementation on Perimenstrual Suicidality

This within-person, crossover, 2-condition, placebo-controlled study compares the impact of two perimenstrual conditions on severity of suicidal symptoms in females with past-month suicidality but minimal risk of imminent suicide attempt. The two conditions are (1) natural perimenstrual withdrawal from estradiol and progesterone (during placebo), (2) perimenstrual stabilization of estradiol and progesterone using transdermal estradiol and oral micronized progesterone.
