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.

Genetic disorders and spermatogenesis.

, 1998
Male infertility affects one man in twenty and a genetic basis seems likely in at least 30% of those men. Genetic regulation of fertility involves the inter-related processes of testicular development, spermatogenesis (involving germ cell mitosis ...

Reverse transcriptase inhibitors enable the generation of fertile spermatids from fetal mouse testes in vitro

Communications Biology
Organ culture systems enabling in vitro spermatogenesis from neonatal mouse testes exist, but differentiation from fetal testes shortly after sex determination remains unsuccessful.

Prevalence of HCMV, HHV‐6, and HSV‐1/2 in the semen of men attending infertility clinics and their association with semen parameters

UroPrecision, EarlyView.
Abstract Background Viral infections have been identified as potential disruptors of male reproductive health. This study aimed to investigate the prevalence of human cytomegalovirus (HCMV), human herpesvirus 6 (HHV‐6), and herpes simplex virus types 1 and 2 (HSV‐1/2) DNA in semen samples from fertile and infertile men within the potential impact of ...

Effect of Salinity Stress on Gut–Brain–Gonad Axis in the Red‐Eared Slider (Trachemys scripta elegans)

Integrative Zoology, EarlyView.
The increase in salinity leads to changes in the gut microbiota and metabolites of Trachemys scripta elegans, affecting the synthesis and secretion of neurotransmitters or precursors, which can inhibit the secretion of reproductive hormones and affect the self‐renewal and differentiation process of spermatogonial stem cells.

Gonadal Development–Related Genes and a Male‐Specific Genetic Marker Identified in the Endangered Sichuan Taimen (Hucho bleekeri)

Integrative Zoology, EarlyView.
Integrated transcriptomic and proteomic analyses were used to validate gonadal development–related genes and to identify a sex‐specific molecular marker in Hucho bleekeri. ABSTRACT Sex determination and differentiation represent fundamental topics in reproductive biology. Sichuan taimen (Hucho bleekeri), a first‐class national protected fish species in

Beyond abstinence: Redefining success in cannabis use disorder treatment

Addiction, EarlyView.
Abstract Background Over two decades of pharmacotherapy research has yet to yield a consistently effective medication for cannabis use disorder (CUD), in part because clinical trials have frequently prioritized abstinence as a primary or key endpoint.
