Experiment

Circulating insulin levels following ovariectomy surgery in B6 mice treated with
letrozole
Summary Data Summary
Investigator Thackray, Varykina
Description Letrozole treatment of pubertal female mice results in hallmarks of PCOS
including elevated androgens, anovulation, polycystic ovaries and a metabolic
phenotype.

Female mice with either Placebo or Letrozole pellets implants (5 weeks) were
fasted for 5 hrs starting at 8am and euthanized using isoflurance overdose.
Blood was collected via a 25G needle through the mouse aorta. Blood is then
processed at 4C and spun down for serum.
