Peroxiredoxin 4 Involved in Spermatogenesis by Affecting Oxidative Stress and Ferroptosis

Andrology, EarlyView.
ABSTRACT Background The main functions of testes are sperm production and androgen secretion in testicular befitting microenvironment. Excessive level of the reactive oxygen species (ROS) from metabolism and cellular events can lead to oxidative stress (OS) and ferroptosis, which injure the functions of mitochondria and endoplasmic reticulum (ER) of ...

Aberrant gene expression by Sertoli cells in infertile men with Sertoli cell-only syndrome.

PLoS ONE, 2019
Sertoli cell-only (SCO) syndrome is a severe form of human male infertility seemingly characterized by the lack all spermatogenic cells. However, tubules of some SCO testes contain small patches of active spermatogenesis and thus spermatogonial stem ...

Cyclic Treatment With WIN 18,446, a Potential Male Contraceptive, is as Effective as Continuous Treatment for Suppression of Spermatogenesis in Mice

Andrology, EarlyView.
ABSTRACT Background Retinoic acid plays a critical role in spermatogenesis during both spermatogonial differentiation and spermiation. Mice lacking enzymes that synthesize retinoic acid, Aldh1a1/1a2, in the testes are infertile. WIN 18,446 reversibly inhibits spermatogenesis by inhibiting ALDH1A1/1A2 and is a promising approach to male contraception ...

Spermatogonial stem cell transfer to a mule [PDF]

, 2015
Spermatogonial stem cell transfer has been studied in various species and suggested potential for success. Bull, stallion, donkey, mule, boar, dog and cat testicles were examined using various injection techniques to determine distribution patterns of ...

Chromodomain Helicase DNA–Binding Proteins and Spermatogenesis: Current Advances

Andrology, EarlyView.
ABSTRACT Background Male infertility is a prevalent clinical condition, with approximately one‐third of cases classified as idiopathic, frequently stemming from impaired spermatogenesis because of dysregulated gene expression. Chromodomain helicase DNA‐binding (CHD) proteins are central chromatin remodelers that orchestrate this epigenetic regulation ...

Assessing a Model for a Complex Systemic Disorder—The Value of Male Mice With a Supernumerary X Chromosome for Klinefelter Syndrome Research

Andrology, EarlyView.
ABSTRACT Introduction Direct experimental investigation of Klinefelter syndrome (KS) in patients is limited because the syndrome manifests heterogeneously and affects multiple organ systems. Studying KS therefore requires a model that captures this complexity as accurately as possible while still permitting controlled experimental manipulation ...

Spermatogonial cells: mouse, monkey and man comparison [PDF]

, 2016
In all mammals, spermatogonia are defined as constituting the mitotic compartment of spermatogene-sis including stem, undifferentiated and differentiating cell types, possessing distinct morphological and molecular characteristics.

Testicular Biopsies in Adolescent and Adult Andrological Patients: The EAA Clinical Guidelines

Andrology, EarlyView.
ABSTRACT Background Histological evaluation of testicular tissue is central to the assessment of infertile men, particularly those at an increased risk of testicular germ cell tumors (TGCT). Traditionally, testicular biopsies have been used primarily for diagnostic purposes, such as the detection of germ cell neoplasia in situ (GCNIS). With advances in
