Official title
Study to Assess Acute Progesterone Suppression of Wake vs. Sleep Luteinizing Hormone Pulse Frequency in Pubertal Girls With and Without Hyperandrogenism
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of this study is two-fold. (1) We will determine if in mid- to late pubertal girls without hyperandrogenism (HA), progesterone (P4) acutely reduces waking luteinizing hormone (LH) frequency to a greater extent than sleep-associated LH frequency. (2) We will determine if in mid- to late pubertal girls with HA, P4 will acutely suppress waking LH frequency to a lesser degree than it does in girls without HA.
