Health risks associated with infertility and non-obstructive azoospermia.
Level 5 - mechanism / opinion, no new human data
Narrative literature review synthesizing previously published studies
PubMed 40231434 · doi:10.4103/aja20256
What was done
The authors conducted a bibliographic literature search on PubMed using MeSH terms for male infertility and azoospermia combined with mortality, neoplasms, chronic disease, diabetes mellitus, and heart diseases to review existing literature on associations between male infertility, specifically non-obstructive azoospermia, and adverse health outcomes.
What was found
The abstract reports no numerical data, effect estimates, or counts of included studies. It reports that infertile men face increased risks of all-cause mortality, various cancers (notably testicular cancer), metabolic syndrome, diabetes, hypogonadism, and cardiovascular disease compared to fertile counterparts, with limited studies indicating similar vulnerabilities in men specifically with azoospermia.
Why it matters
This review emphasizes that non-obstructive azoospermia and male infertility may act as biomarkers for systemic health conditions, supporting broader clinical evaluations and ongoing monitoring beyond reproductive care.
Limits
The abstract contains no quantitative metrics or sample sizes. As a narrative review rather than a systematic review or meta-analysis, the synthesis lacks formal quality assessment or pooled estimates. The authors also note that research specifically dedicated to azoospermia remains limited.
