reproductive system
• unlike in wild-type mice, follicles exhibit a marked deficiency in granulose cells
• mice exhibit increased antral follicle numbers compared to in wild-type mice
• however, no cysts form and interstitial glandular cell organization is normal
• despite the fertility of male mice, female mice exhibit reduced fertility to infertility

homeostasis/metabolism
• mice fail to superovulate when treated with gonadotropins because follicles reach a preovulatory stage but fail to mature unlike in similarly treated wild-type mice

endocrine/exocrine glands
• unlike in wild-type mice, follicles exhibit a marked deficiency in granulose cells
• mice exhibit increased antral follicle numbers compared to in wild-type mice
• however, no cysts form and interstitial glandular cell organization is normal

cellular
• unlike in wild-type mice, follicles exhibit a marked deficiency in granulose cells
