Table 1 Numbers (n) of mice, age in days (sd), mean body weight in grams (sd) and estimated mean total lifetime ovulation number (OV#: minimum – maximum estimate) in mice subjected to incessant ovulation (IO) or repeated pregnancy (BR) from 6–12 months (m) of age.

From: E-cadherin expression and bromodeoxyuridine incorporation during development of ovarian inclusion cysts in age-matched breeder and incessantly ovulated CD-1 mice
