Influences of Female Sex and Reproductive Hormones on Physiological Aspects of Heat Acclimation

Women are often understudied in thermal physiology research, leaving recommendations for Soldier safety and performance in hot conditions based largely on data collected in men. Female sex hormones estradiol and progesterone clearly have non-reproductive physiological effects, including influences on thermoregulatory and cardiovascular function. However, mechanisms of differing physiological adaptations to …

Impact of Estradiol on Endothelial Function in Peri-Menopausal Women

The purpose of this study is to identify the impact of estradiol (E2) on the mechanisms that regulate vascular endothelial function in peri-menopausal (PERI) women. This study is the first step in understanding factors contributing to endothelial dysfunction in women with advancing reproductive age and in response to E2 administration.

Reproductive Function in Women With Bipolar Disorder

Many studies have shown that patients with bipolar disorder are prone to reproductive dysfunction, including polycystic ovary syndrome, hyperprolactinemia, and amenorrhea. However, there is still considerable disagreement about the causes of reproductive dysfunction in patients with bipolar disorder. This study will evaluate the reproductive function of female patients with bipolar …

Ultrasound Characterization of Ovarian Follicle Dynamics in Women With Amenorrhea

In women with regular menstrual cycles, antral follicles have been shown to grow in synchronous cohorts, called waves, 2-3 times in a menstrual cycle. It is unknown whether these waves of follicle growth also occur in women with amenorrhea or if there is abnormal/absent follicle growth. Further, oligo- or amenorrhea …
