Clinical Trial 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.

Description:

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.

Furthermore, the study aims to assess if the blood and seminal alterations of infertile patients have similarities with the same fluids of elderly patients, validating from a metabolomic and microbiomic point of view the hypothesis of premature aging of infertile patients.
