2. Fig 1
Sample recordings of (A) 1 non-SCI and (C) 1 SCI subject, along with an expanded tracing of the (B) non-SCI subject to match the time unit of the SCI subject. Abbreviations: PT, penile tumescence; BS, bulbocavernosus; RA, rectus abdominalis; HR, heart rate.

3. Fig 2
Cardiovascular changes in each subject as a function of sexual stimulation from baseline (B) to ejaculation (P0) and from 2 minutes (P2) to 20 minutes (P20) after ejaculation. Error bars correspond to standard errors (SEs) during the 5 repeated sessions in each subject. Abbreviation: BP, blood pressure.

H-reflex changes in each subject as a function of sexual stimulation from baseline (B) to ejaculation (P0) and from 2 minutes (P2) to 20 minutes (P20) after ejaculation. Error bars correspond to the SEs during the 5 repeated sessions in each subject.

5. Fig 4
A sample recording of (A) the muscular activity during a failure session. (B) The average changes in cardiovascular responses during the failure sessions. (C) The drops in H-reflex amplitude (from baseline to minimal H-reflex value) as consecutive bouts of stimulation were attempted during the failure sessions. (D) A histogram that illustrates the drops in H-reflex on successful sessions (S) and on successive bouts of vibratory stimulation (F1 to F5) during failure sessions.
