NCT06181851

Brief Summary

The study aims to carry out a translational analysis of the microbiome and metabolomics in patients suffering from non-obstructive azoospermia, with the aim of investigating prognostic factors predictive of the possible finding of spermatozoa following testicular pulp extraction and differences in blood and seminal level with the fertile population to identify etiopathogenic pathways of this condition.

Outcome Measures

Primary Outcomes (1)

  • Prognostic role of the blood and semen samples

    Metabolomics and microbiome signature fertile and infertile men predicting possible finding of spermatozoa

    Baseline

Study Arms (3)

Infertile men

Patients diagnosed with idiopathic non-obstructive azoospermia

Other: Analysis of microbiome and metabolomics

Fertile men

fertile subjects (pregnancy within 12 months of the start of the research by the couple, according to WHO 2010 criteria)

Other: Analysis of microbiome and metabolomics

Old fertile men

Subjects known to have been fertile subjects (pregnancy within 12 months of the start of the research by the couple, according to WHO 2010 criteria)

Other: Analysis of microbiome and metabolomics

Interventions

Analysis of microbiome and metabolomics through the assessment of blood and semen parameters
