Abstract excerpt
Estrogen receptor beta (ERbeta) is highly expressed, but ERalpha is not detectable in granulosa cells in the mouse ovary. In ERbeta knockout (BERKO) mice, there is abnormal follicular development and very reduced fertility. At 3 wk of age, no significant morphologic differences were discernable between wild type (WT) and BERKO mouse ovaries, but by 5 mo of age, atretic follicles were abundant in BERKO mice and...
