Figure 4. CIH and age impaired consummatory intromission behaviors.

Figure 4

Middle-aged rats had significantly longer intromission latency (A) and fewer intromissions (C) than young intact male rats. CIH did not alter behavior in middle-aged rats. In young intact male rats, CIH increased intromission latencies and decreased the frequencies of intromissions. GDX rats did not exhibit consummatory sexual behaviors, whereas testosterone replacement in GDX rats decreased intromission latency (B) and increased intromission frequency (D). Fisher’s LSD post hoc analyses: * p ≤ 0.05 normoxia vs. CIH; ** p ≤ 0.05 vs. young normoxia; *** p ≤ 0.05 vs. young intact rats; # p ≤ 0.05 vs. young GDX.
