NCT06841328

Brief Summary

This study investigates the safety and efficacy of stem cell or stem cell-derived exosome therapy for gonadal failure, including testicular failure, hypogonadism, ovarian insufficiency, and premature ovarian failure (POF). Conducted at First IVF Clinic, Dubai, it will include 60 participants (30 males, 30 females) aged 20-50 years who have not responded to conventional treatments such as HRT, TRT, or ART. Participants will receive intra-gonadal (testicular or ovarian) injections of stem cells or exosomes, with follow-ups at 3, 6, 9, and 12 months to monitor hormonal changes, gonadal function, and potential adverse effects. The study aims to determine whether regenerative therapy can restore hormone production, enhance reproductive function, and regenerate gonadal tissue, providing a novel, culturally appropriate fertility treatment in the UAE, where donor sperm and eggs are not permitted. By bridging the gap between preclinical research and clinical application, this study could offer new hope to individuals with gonadal failure, advancing the field of regenerative reproductive medicine.

Outcome Measures

Primary Outcomes (1)

  • Change in reproductive capacity

    We will evaluate hormonal changes (testosterone, estradiol, FSH, AMH) and sperm parameters

    12 months

Secondary Outcomes (1)

  • Gonadal Function

    12 months

Other Outcomes (1)

  • Adverse Effects

    12 months

Study Arms (2)

Male

Male patients aged 20 to 50 years. Diagnosed with testicular failure (low testosterone) or hypogonadism (impaired gonadal function), or azoospermia due to production defect (no sperm in ejaculate)

Procedure: Stem cells

Female

Female patients aged 20 to 50 years. Diagnosed with premature ovarian failure (POF) or ovarian insufficiency, confirmed through clinical, hormonal, and imaging assessments.

Procedure: Stem cells

Interventions

Stem cellsPROCEDURE

The administration of stem cell or stem cell-derived exosome therapy as a regenerative treatment for gonadal failure in both men and women. The intervention involves a single intra-gonadal injection (testicular or ovarian) of adipose-derived stem cells (ADSCs) or exosomes.

Study Population

The study population will consist of adult male and female patients aged 20 to 50 years who are diagnosed with testicular or ovarian failure and are seeking treatment at First IVF and Day Surgery Center. Participants will be recruited from the pool of patients under the care of the PI or the co-Is. Eligibility will include individuals with confirmed testicular or ovarian failure based on clinical, hormonal, and imaging criteria who have not responded adequately to conventional treatments such as hormone therapy (HT).

You may not qualify if:

  • Severe comorbid conditions, such as advanced cardiovascular disease, renal failure, or uncontrolled diabetes.
  • Active malignancies or history of cancer within the past 5 years.
  • Active infections or systemic inflammatory conditions.
  • History of testicular surgery or trauma that could interfere with the study outcomes.
  • Use of anticoagulants or medications that may contraindicate stem cell or stem cell-derived exosome therapy.
  • Participation in another investigational drug or treatment study within the past 6 months.
  • Contraindications to stem cell or stem cell-derived exosome therapy, such as immune deficiencies or allergies to any treatment components.
  • Severe neurological disorders or cognitive impairment may limit the ability to provide informed consent or follow study instructions.
  • Any condition that, in the investigator's opinion, could interfere with the study or pose an undue risk to the patient.
  • Women with a primary diagnosis of psychogenic ovarian dysfunction or infertility.
  • History of ovarian surgery or trauma that could interfere with the study outcomes.
