(A) Serum AMH levels following treatment with rhGH or saline (^# P > 0.05, vs Wt group of the same age group respectively; **P < 0.01, vs Wt group/young). (B) The average total number of ovulated oocytes collected after hormonal stimulation (^a P < 0.05, vs Wt group/young; ^b P < 0.05, vs Wt group/aged). (C) Formation rates of MII-stage oocytes (^a P < 0.05, vs Wt group/young; ^b P < 0.05, vs Wt group/aged). (D) ATP concentration of each single oocyte (^a P < 0.05, vs Wt group/young; ^b P < 0.05, vs Wt group/aged). (E) Mean mtDNA copy numbers per oocyte (^# P > 0.05, vs Wt group in both young and aged mice), most of the samples have approximately 170,000 copies. Descriptive statistics: minimum = 28,750; maximum = 537,664.
