Brief Summary:
Efficacy of Intracavernous injection of Wharton jelly Mesenchymal stem cells for the treatment of erectile dysfunction in diabetic patients.

Condition or disease Intervention/treatment Phase
Erectile Dysfunction Associated With Type 2 Diabetes Mellitus Biological: Wharton Jelly Mesenchymal stem cells Phase 1 Phase 2

Detailed Description:

This study will be conducted at the Cell Therapy Center (CTC), Jordan, in which 22 male patients ranging from 25-70 years diagnosed with erectile dysfunction will be selected. This diagnosis is based on medical history, validated questionnaires, physical examinations, laboratory tests and specific diagnostic tests.

The patients are followed by clinical assessment, laboratory investigations as well as Doppler ultrasound.

The investigators hypothesize that the intracavernous injection of stem cells will facilitate the recovery of erectile function resulting in satisfying clinical outcomes in patients.

Arm Intervention/treatment
Experimental: Dose 1
Dose I of Wharton Jelly Mesenchymal stem cells (WJ-MSC) Two intracavernous injections of 20 million of WJ-MSC cells will be given to erectile dysfunction patients at baseline and 4th week of follow up
Biological: Wharton Jelly Mesenchymal stem cells
Intracavernous injection of Wharton Jelly Mesenchymal stem cells.

Primary Outcome Measures :
  1. Assessment of the efficacy of injecting Wharton Jelly derived Mesenchymal Stem Cells by Penile Doppler ultrasonography. [ Time Frame: 12 months ]
    Patients will be evaluated for the efficacy of the intracavernous injection of Wharton Jelly derived Mesenchymal Stem Cells by Penile Doppler ultrasonography in which peak systolic velocity of the cavernosal arteries will be measured.

  2. Assessment of the efficacy of injecting Wharton Jelly derived Mesenchymal Stem Cells by SHIM/IIEF/EHS questionnaires [ Time Frame: 12 months ]
    The efficacy of the intracavernous injection of Wharton Jelly will be evaluated by scoring the SHIM/IIEF/EHS questionnaires.
