Role of testicular fine‐needle aspiration in the modern male reproductive urologist′s practice

UroPrecision, EarlyView.
Abstract Background Azoospermia affects 10%–15% of infertile men, with non‐obstructive azoospermia (NOA) most often managed by microdissection testicular sperm extraction (mTESE). Despite AUA/ASRM guidelines recommending mTESE, some urologists employ testicular fine‐needle aspiration (TFNA) mapping as a diagnostic adjunct.

Testicular Echobiometry and Sperm Characterization in Oncilla (Leopardus tigrinus) From the Caatinga Biome

Zoo Biology, EarlyView.
We describe testicular echobiometry and sperm characterization in oncilla (Leopardus tigrinus) from the Caatinga biome, Ceará, Brazil. ABSTRACT Among neotropical small felids, the Leopardus tigrinus is classified as vulnerable by the International Union for Conservation of Nature, but studies on reproductive morphology and physiology are scarce for ...
