Development of a nomogram for sperm retrieval at microTESE for idiopathic non‐obstructive azoospermia in a multi‐center cohort study

Andrology, Volume 14, Issue 5, Page 1202-1208, July 2026.
Abstract Background Non‐obstructive azoospermia (NOA) affects approximately 10% of infertile men and represents a major challenge in assisted reproductive technology (ART). A model that includes histological variants could be helpful in predicting sperm retrieval rate (SRR) after microdissection testicular sperm extraction (mTESE) in patients affected ...

Testicular mRNA‐LNP Delivery: A Novel Therapy for Genetic Spermatogenic Disorders

Advanced Science, Volume 13, Issue 22, 17 April 2026.
In the current study, we developed a novel therapy for genetic spermatogenic disorders. It was revealed that in vivo delivery of mRNA LNP3 could restore spermatogenesis in Msh5D486Y/D486Y and Maps KO mouse models with meiotic arrest. Notably, the offspring without genomic integration was born using ICSI derived from the rescue of Msh5D486Y/D486Y mouse ...

Fluorine‐Free Ionic Liquid Electrolytes Featuring Biomass‐Derived Heterocyclic Anions for Variable Temperature Supercapacitors

Advanced Energy and Sustainability Research, Volume 7, Issue 2, February 2026.
This study introduces two new fluorine‐free ionic liquids (ILs) produced by coupling biomass‐derived heterocyclic anions, i.e., THP and 3‐FuA, with P4444 cation. Both the ILs display enhanced capacitance with increasing temperature, underscoring their potential as fluorine‐free electrolytes for supercapacitors.

Hormonal Therapy Before Sperm Retrieval in Men With Non‐Obstructive Azoospermia: From Controversy to Precision Using the APHRODITE Criteria

Reproductive Medicine and Biology, Volume 25, Issue 1, January/December 2026.
ABSTRACT Purpose To review the biological rationale, clinical evidence, limitations, and future directions for hormonal therapy before sperm retrieval in men with non‐obstructive azoospermia (NOA), with emphasis on phenotype‐based selection using the APHRODITE criteria.

Testicular volume in non‐obstructive azoospermia with a history of bilateral cryptorchidism may predict successful sperm retrieval by testicular sperm extraction

Reproductive Medicine and Biology, 2020
Purpose Cryptorchidism is one of the most common causes of non‐obstructive azoospermia (NOA) in adulthood. Even if early orchidopexy is performed to preserve fertility potential, some patients still suffer from azoospermia.
