Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 62 years
  • All sexes
  • Healthy volunteers accepted
  • Adult

Who may be able to join

  • 40 postmenopausal women (age 40-62) and 30 men (age 18-45) will be recruited if they are healthy, at their lifetime maximal weight, have been weight stable for at least six months prior to entry, have a BMI between 19 and 39.9 kg/m2, and be willing to commit to not making significant changes to their diet or daily activities while enrolled in the study.

Who cannot join

  • Subjects will be excluded for potential confounders on body weight, cortisol production rates, sex steroid metabolism, or contraindications to strong magnetic fields:
  • Age less than 18 to exclude those who might be experiencing alterations in cortisol production or weight as a result of adolescent growth
  • Subjects who exercise > 30 minutes/day, 3 times a week
  • Smokers
  • Heavy alcohol drinkers (> 2 drinks/ day)
  • Subjects with medical diagnosis including diabetes, heart disease, and cancer
Show all 17Show fewer
  • Subjects with psychiatric illness (i.e., depression, psychosis, bipolar, schizophrenia; or are taking medications for these disorders)
  • BMI 40 kg/m2, since obesity influences levels of sex steroids and sex hormone binding globulin; or body weight > 136 kg (300 lbs), since this is the weight limit for the DEXA and MR machines
  • Presence of metal in the body such as body piercing, shrapnel, cardiac pacemakers or aneurysm clips
  • Endocrine diseases affecting body composition, such as untreated hypothyroidism or Cushing's syndrome, will be excluded by history and physical examination, or by laboratory evaluation if necessary.
  • Women with a contraindication to estrogen use will also be excluded, including: an estrogen dependent malignancy, active thrombophlebitis, history of deep venous thrombosis, hypertriglyceridemia, untreated hypertension, cardiovascular disease, migraine headaches, or current tobacco use.
  • Women with frequent hot flashes or disrupted sleep will also be excluded since they will be unlikely to tolerate randomization to placebo and continued symptoms and altered sleep cycles will independently affect cortisol secretion patterns.
  • All volunteers will have had a normal mammogram within the previous 12 months.
  • Any subject with previously unevaluated postmenopausal bleeding will not be included and, instead, will be referred to a physician for evaluation.
  • Women who underwent surgical menopause (bilateral ovariectomy) must be at least one year out from their surgery before considered eligible so as to allow weight stabilization after the procedure.
  • Men will have had a prostate exam by their primary health provider within the previous year or by the PI at the time of screening for this study.
  • Any subjects taking a blood thinning medication or with an abnormal exam will not be included and, instead, will be referred to a physician for evaluation

About this study

The purpose of this study is to determine if estrogen or testosterone can affect cortisol levels and where fat builds up in our bodies.

Read the detailed description

Subjects will be studied 3 or 4 times on the inpatient unit of the Oregon Clinical and Translational Research Center. During each visit, testing will include measuring the amount of whole body fat and fat in the stomach area, muscle, and liver; levels of cortisol in the blood, urine, and fat tissue (taken from a biopsy); how well insulin works (insulin sensitivity).

Being tested
Placebo injection, Depo Lupron/Aromatase inhibitor, Depo Lupron/placebo, placebo, Estrogen cream

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. To measure 24-hour CPR, free cortisol, and cortisol binding globulin levels in plasma; HSD 1 activity, glucocorticoid receptor binding, and cortisol levels in adipocytes; and urinary excretion of cortisol, cortisone and their metabolites.

    Measured: Before and after hormone replacement therapy

Secondary outcomes (1)
  1. To measure intramyocellular fat and intrahepatic fat by MRS, visceral and subcutaneous abdominal fat by CT scan, body composition (fat mass, lean mass, and bone mass) by DXA, and insulin sensitivity.

    Measured: Before and after hormone replacement therapy

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 17 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 16 Dec 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

To measure 24-hour CPR, free cortisol, and cortisol binding globulin levels in plasma; HSD 1 activity, glucocorticoid receptor binding, and cortisol levels in adipocytes; and urinary excretion of cortisol, cortisone and their metabolites. (time frame: Before and after hormone replacement therapy). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Dec 2022.
