Age and treatment changes in estradiol levels. Estradiol levels decreased with age and were not changed from age-matched control mice with transplantation of young ovarian tissue. CTL 17 months (n = 7) = age-matched controls, GC 17 months (n = 9) = received germ cell containing 60-day ovaries at 13 months. GD 17 months (n = 12) = received germ cell depleted 60-day ovaries at 13 months. OSC 17mo (n = 7) = received transplantation of isolated somatic cells from 60-day ovaries at 13 months.
