Uterine abnormalities in Esr1^tm3.1Ksk/Esr1^tm3.1Ksk mice

reproductive system

decreased endometrial gland number ( J:176459 )

♀

absent corpus luteum ( J:176459 )

♀

abnormal ovarian follicle morphology ( J:176459 )

♀ • hemorrhagic

decreased primordial ovarian follicle number ( J:176459 )

♀

uterus cyst ( J:176459 )

small uterus ( J:176459 )

♀

uterus hypoplasia ( J:176459 )

♀

absent estrous cycle ( J:176459 )

♀

homeostasis/metabolism

increased circulating estradiol level ( J:176459 )

• 2-fold

increased luteinizing hormone level ( J:176459 )

• 4-fold

abnormal response/metabolism to endogenous compounds ( J:176459 )

• uterine tissue in ovariectomized mice fails exhibit uterotropic responses to estradiol treatment compared to in similarly treated wild-type mice
