Myotube migration to cover and shape the testis of Drosophila depends on Heartless, Cadherin/Catenin, and myosin II

open access: yesBiology Open, 2017
During Drosophila metamorphosis, nascent testis myotubes migrate from the prospective seminal vesicle of the genital disc onto pupal testes and then further to cover the testes with multinucleated smooth-like muscles.

Clinical presentation, management and follow-up of 83 patients with Leydig cell tumors of the testis: a prospective case-cohort study [PDF]

open access: yes, 2019
LCTs are more frequent than generally believed, are associated with male infertility, cryptorchidism and gynecomastia, and should be treated conservatively (in compliant patients) with active surveillance, which appears to be a safe alternative to ...

Dissent of the testis [PDF]

open access: yesBMJ, 2007
We previously reported that two chocolates—Teasers and Truffles (Celebrations, Masterfoods UK, Melton Mowbray)—were strikingly similar to the 8 ml bead of the orchidometer used to assess testicular volume.1 We therefore suggested that they could be used to stage puberty in males and, because of their wide availability and low cost, commended their use.

PHOSPHO1 Suppresses Ferroptosis in Retinal Pigment Epithelial Cells by Reducing the Levels of Phosphatidylethanolamine Molecular Species

open access: yesAdvanced Science, Volume 12, Issue 28, July 24, 2025.
Iron‐induced lipid peroxidation of phosphatidylethanolamine (PE) species is the key driver of ferroptosis. The authors discovered that PHOSPHO1 lowers the level of PE in retinal pigment epithelial cells thus reducing the formation of lipid peroxides. Lowering PE levels can also prevent the creation of autolysosomes, reduce the production of free iron ...

m6A Reader hnRNPA2B1 Modulates Late Pachytene Progression in Male Meiosis Through Post‐Transcriptional Control

open access: yesAdvanced Science, EarlyView.
As an m6A reader, hnRNPA2B1 predominantly regulates specific transcripts (e.g., Ep400, Rrs1) that are essential for chromosome organization and remodeling in an m6A‐dependent manner. Furthermore, it is demonstrated to interact with factors involved in mRNA processing and translation. This dual functionality is pivotal for ensuring the proper occurrence

Abdominal wall ectopic testis - Case report and review of literature

open access: yesJournal of Pediatric Surgery Case Reports, 2018
Undescended testis is a common condition which affects about 2–4% of male infants and more commonly seen in preterm infants. The descent of testis is a complex process which requires cross talk between various hormones and testes.

Lifelong testicular differentiation in Pleurodeles waltl (Amphibia, Caudata)

open access: yesReproductive Biology and Endocrinology, 2009
Background In numerous Caudata, the testis is known to differentiate new lobes at adulthood, leading to a multiple testis. The Iberian ribbed newt Pleurodeles waltl has been studied extensively as a model for sex determination and differentiation ...
