Spatiotemporal Expression of ARRDC5 in Mammalian Spermatogenesis

Andrology, EarlyView.
ABSTRACT Background Spermiogenesis is the final phase of sperm development during which haploid round spermatids transform into specialized spermatozoa and occurs across distinct stages of sperm production in the seminiferous epithelium. Abnormalities in this process lead to malformations and an inability of sperm to fertilize eggs.

Father–Son Comparison of Reproductive Traits

Andrology, EarlyView.
ABSTRACT Background Little is known about the relative contribution of genetic and environmental factors on male reproductive function. Objectives We studied in a cross‐sectional setting, whether testicular function and genital size correlate in father–son pairs.

Immobilization of Sertoli cells on islets of Langerhans

, 2013
Sertoli cells play a crucial role in creating the immunoprivileged environment of the testis. We examined the survival of islets of Langerhans after co-transplantation with Sertoli cells. Sertoli cells near islets should protect the graft from rejection.

The Impact of Common Medications on Male Fertility: An Updated Systematic Review

Andrology, EarlyView.
ABSTRACT Background Compared with those of cytotoxic treatments, the potential effects of common medications on the fertility of men trying to conceive currently or planning to conceive in the future are less well described. The use of common medications may modify the gonadotropic axis, spermatogenesis, and epididymal maturation or alter male ...

Interactions between Sertoli cells and germ cells in the testis

, 1994
The production of mature spermatozoa requires a complex interaction between Sertoli cells and germ cells. Sertoli cells regulate aspects of germ cell division and differentiation while germ cells provide signals that modulate Sertoli cell functions. Germ

Lactate‐Responsive Glycogen Dynamics Are Associated With Bull Sperm Motility and Fertilization Under Glucose‐Limited Conditions

Andrology, EarlyView.
ABSTRACT Background Mammalian sperm need to undergo hyperactivation, capacitation, and acrosome reaction to achieve fertilization competence. However, the female reproductive tract presents contrasting metabolic environments. The uterus is glucose‐rich, and the oviduct is lactate‐rich and glucose‐limited.

Androgens Modulate Tumor–Immune Interactions in Testicular Germ Cell Tumors

Andrology, EarlyView.
ABSTRACT Background The majority of testicular germ cell tumors (TGCT) are derived from the germ cell neoplasia in situ and arise after puberty in the local presence of high levels of testosterone. The seminoma subtype features a rich inflammatory infiltrate which impacts tumor progression but the role of testosterone in shaping tumor–immune ...

Pubertal Dynamics of Sertoli and Leydig Cell Dysfunction in Klinefelter Syndrome

Clinical Endocrinology, EarlyView.
ABSTRACT Context Klinefelter syndrome (KS), defined by a 47, XXY karyotype, is commonly associated with progressive testicular failure. The precise timing of Sertoli and Leydig cell dysfunction during puberty remains unclear. Objective To determine the onset and progression of testicular insufficiency during puberty in KS, and to assess whether ...

Wt1 Is Required for the Regression of Müllerian Ducts in Male Mice by Inducing Wif1 and Osx Expression

Cell Proliferation, EarlyView.
Wt1 expressed in the MD mesenchyme promotes MD regression by inducing Wif1 and Osx transcription. In male mice, mesenchyme‐specific inactivation of Wt1 results in MD retention. ABSTRACT In mammals, Müllerian ducts (MDs) are the precursors of the female reproductive tract which regress in males during embryonic development.

GSK3α‐mediated regulation of the RNA demethylase fat mass and obesity‐associated protein (FTO) during murine spermatogenesis

The FEBS Journal, EarlyView.
FTO regulates mRNA stability and translational efficiency through its m6A‐demethylation activity. GSK3 functions as an upstream regulator of FTO, leading to its inhibition via phosphorylation. In male germ cells, FTO activity is kept in check by GSK3α.
