The overarching aims of this study are to:

  1. Characterize the rate of in vivo adipogenesis, and changes in adipose tissue gene and protein expression, in the scABD and scFEM depots of women undergoing surgical menopause (↓E2, ↑FSH).
  2. Characterize the rate of in vivo adipogenesis, and changes in adipose tissue gene and protein expression, in the scABD and scFEM depots of women undergoing gonadal suppression (↓E2, ↓FSH).


This is a cross-sectional study where two groups of premenopausal women (ages 18-50 y) will be enrolled in a parallel arm study:

  • Arm 1 (Surgical Menopause): up to 6 women undergoing laparoscopic, elective bilateral oophorectomy [Site: Pennington Biomedical Research Center].
  • Arm 2 (Pharmacology-Induced Menopause): up to 6 women undergoing gonadal suppression via leuprolide acetate (Lupron [AbbVie Inc.]) [Site: UC-Denver].

We will compare each arm of women to non-oophorectomized, premenopausal women (controls) with normal menstrual cycles (Apple&Pear study; NCT01748994; PI: Ravussin) selectively matched (1:2) for age and BMI. The Apple&Pear study uses the same in vivo adipogenesis labeling protocol, with similar age and BMI criteria, as the proposed study.
