Increased Estradiol Levels Effect on Leptin Expression in Midluteal Endometrial Tissue of Macaca Nemestrina (Southern Pig-Tailed Macaques).

To measure the effect of serum estradiol (E2) levels on leptin expression in Macaca nemestrina (southern pig-tailed macaque) endometrial tissue. This study used paraffin-embedded midluteal phase endometrial tissue blocks of Macaca nemestrina from previous study. Included subjects were 15 female macaques of reproductive age (8-10 years) with a previous history of producing offspring, which were divided into four groups: groups administered with 30 IU, 50 IU, and 70 IU r-FSH (intervention group), and no r-FSH (control group).
