Bladder Outlet Obstruction Secondary to a Prostatic Cyst in a Young Adult: A Rare Case Report. [PDF]

open access: yesClin Case Rep
ABSTRACT Bladder outlet obstruction secondary to an obstructing prostatic cyst is a rare clinical entity. Incomplete regression of the Müllerian duct is supposed to be the cause of such cysts. Clinical features can range from acute bladder outlet obstruction to chronic urinary retention, oligospermia, and prostatitis‐like symptoms.

HATCHLING SEX RATIOS AND LOCOMOTOR PERFORMANCE OF MIDLAND PAINTED TURTLES (CHRYSEMYS PICTA MARGINATA) [PDF]

open access: yes, 2014
The primary objectives of this study were to understand how canopy cover and nest temperatures affect hatchling sex ratios and locomotor performance (i.e., swimming sprint speed and righting response) of Chrysemys picta marginata nests.

Persistent Müllerian duct syndrome

open access: yesDefinitions, 2020
Anti-Mullerian hormone (AMH), also known as Mullerian-inhibiting substance, is produced by Sertoli cells of the fetal testis and normally causes regression of the Mullerian structures that would otherwise persist in the pathway of normal female ...

Histological Characterization and Comparative Transcriptomic Analysis of Gonads During Early Sex Differentiation in the Northern Snakehead (Channa argus)

open access: yesAnimal Research and One Health, EarlyView.
This study delineates the early sex differentiation timeline in the northern snakehead (Channa argus). These findings provide a foundation for future sex‐control breeding in this economically important species. ABSTRACT The northern snakehead (Channa argus) is an economically important aquaculture species in China.

Modern competency‐based teaching of human sexual development

open access: yesAnatomical Sciences Education, EarlyView.
Abstract Embryology is an integral part of anatomy and a key subject in basic medical education. The development of the sexual tract, which is closely associated with the formation of the urinary tract and the organs of continence, is particularly complex and relevant for many medical disciplines.

Role of SoxE transcription factors in development and disease

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Sox8, Sox9, and Sox10 arose by multiple rounds of genome duplications from a single SoxE gene in ancestral vertebrates. In this review, we will briefly discuss the molecular structure and function of SoxE transcription factors and their evolutionary origin. We will then discuss their expression, function, and developmental disorders.
