Eligibility Criteria:
Inclusion Criteria:~* Premenopausal volunteers will be healthy, eumenorrheic women, aged 18-45 yrs. Eumenorrheic status will be verified by regular menses (no missed cycles in previous year; cycle length 25-35 d).~* Postmenopausal volunteers will be healthy women who have no menses for at least 12 months~Exclusion Criteria:~- Body mass index (BMI) \> 35 kg/m2~Additional exclusion criteria for premenopausal women~* Hormonal contraceptive use (past 6 mo.)~* Pregnant, lactating or intention to become pregnant during the period of study~Additional exclusion criteria for postmenopausal women~* History or current use of hormonal replacement therapy (HRT)~* Women who have undergone surgical menopause.

- Maximum Age: 99 Years
- Healthy Volunteers: t

Study Arms:
- Pre-menopausal women (Type: EXPERIMENTAL): To determine if natural declines in endogenous E2 contribute to changes in BAT activity, the investigators will compare BAT activity in pre-and post-menopausal women. We will also explore whether suppression of ovarian hormones in pre-menopausal women (using leuprolide acetate) impairs BAT activity.
- Post-menopausal women (Type: NO_INTERVENTION): To determine if natural declines in endogenous E2 contribute to changes in BAT activity, the investigators will compare BAT activity in pre-and post-menopausal women.

Based on this trial design, predict the completion outcome and termination type (if applicable).
