Welcome to SCIRE Professional

Prostaglandin E2 is a group of hormone-like substances that contribute to a wide range of body functions including the contraction and relaxation of smooth muscle, the dilation and constriction of blood vessels and control of blood pressure.

Prospective controlled trial

N=5

Population: 5 patients with complete SCI; age range: 25-37 years; level of injury: C5-T4, 5-108 months post-injury.

Treatment: trans-rectal electrical ejaculation with and without intravenous administration of Prostaglandin E2.

Outcome Measures: heart rate, blood pressure, electrocardiogram.

1.   Resting BP decreased and resting HR increased with Prostaglandin E2.

2.   BP decreased during electrical stimulation, which enabled tolerance of more intense stimulation and successful ejaculation in 2 patients.

 

Discussion

Frankel and Mathias (1980) studied five subjects; 3 subjects underwent administration with and without Prostaglandin E2 and showed that the level of BP recorded during electrical ejaculation decreased with the drug.

Conclusion

  • There is level 2 evidence from a very small prospective controlled study (Frankel & Mathias 1980) which used subjects as their own controls and showed that the level of BP recorded during electrical ejaculation was substantially reduced with Prostaglandin E2.
  • Prostaglandin E2 is effective for reducing BP responses during eletroejaculation.
