endocrine/exocrine glands
• hyperplasia of spindle-like stromal cells (J:185012)
• while aged females develop ovarian cysts, young females display normal steroidogenic and reproductive function (J:185012)
• cysts show a severe reduction or lack of corpus luteum in aged ovaries, suggesting a cessation of estrous cycling (J:185012)
• ovarian cysts are characterized by thecal-interstitial hyperplasia (J:185012)
• 80% of females develop severe ovarian cysts; cysts increase in size with age (J:185012)
• ovarian cysts show increased steroidogenic capacity as indicated by an increase in the activation of steroidogenic signaling and the presence of lipids in the cells surrounding the cystic lumen (J:185012)
• young females treated with leutinizing hormone alone or with GnRHAnt (to induce cyst formation) show an approximate 3-fold increase in cystic area in the ovaries compared to treated wild-type mice, however hyperinsulinemia is not seen in these mutants (J:185012)

homeostasis/metabolism
• aged females exhibit a 2-fold increase in serum testosterone levels
