Table 1.

Remaining life expectancy for mice in five cohorts of female CBA mice. Treatments: prepubertal ovariectomy with receipt of young transplant ovary at 5, 8 and 11 months; intact (IT) control; prepubertal ovariectomy without transplant (OX control), and long-term ovariectomy (OX) control cohorts. Value in parentheses gives the number alive at the specific age. Life expectancy of each transplant cohort was compared at 11 months to both the IT and the OX controls and each contrast was significant (P< 0.05)
