CWF19L2 is Essential for Male Fertility and Spermatogenesis by Regulating Alternative Splicing

Advanced Science
The progression of spermatogenesis along specific developmental trajectories depends on the coordinated regulation of pre‐mRNA alternative splicing (AS) at the post‐transcriptional level.

Endocrine control of spermatogenesis in the ram.

Journal of reproduction and fertility. Supplement, 2019
In the ram, the size of the testes is related to the concentrations of FSH, LH and testosterone in the blood. A significant linear relationship is observed between testicular size and the level of FSH until a maximum after which no further increase in ...

Organoids and organ‐on‐a‐chip models for investigating the pathophysiology of the human reproductive system

Interdisciplinary Medicine, EarlyView.
Organoids and organ‐on‐a‐chips are advancing reproductive system research. In the female reproductive system, applications include cancer organoid models, placental chips, and hormone simulation models. For the male reproductive system, research focuses on drug resistance mechanisms, co‐culture platforms, and infertility studies. These refined in vitro

Effects of 17α‐Ethinylestradiol on Development and Gonadal Differentiation in the Estuarine Mummichog, Fundulus heteroclitus

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT In fish, sex determination and gonadal development are controlled by various genetic and environmental factors. In this study, experiments were conducted on the estuarine mummichog (Fundulus heteroclitus) to investigate gonadal differentiation following exposure to the synthetic estrogen, 17α‐ethinylestradiol (EE2).

Induction of Spermatogenesis and Its Predictors in Men with Prepubertal-Onset Hypogonadotropic Hypogonadism Undergoing Gonadotropin Therapy

The World Journal of Men's Health
Purpose: To evaluate the outcomes of gonadotropin therapy (GT) using human chorionic gonadotropin (hCG) and recombinant follicle-stimulating hormone (rFSH) for inducing spermatogenesis in men with prepubertal-onset hypogonadotropic hypogonadism (HH ...
