The use of deidentified organ donor testes for research

Andrology, EarlyView.
Abstract Our knowledge of testis development and function mainly comes from research using mammalian model organisms, primarily the mouse. However, there are integral differences between men and other mammalian species regarding cellular composition and expression profiles during fetal and post‐natal testis development and in the mature testis ...

The impact of Connexin 43 deficiency on the cell shape and cytoskeleton of murine Sertoli cells: A house with ramshackle walls?

PLoS ONE
Genetically induced loss of the gap-junction protein Connexin 43 (Cx43) in murine Sertoli cells leads to an arrest of spermatogenesis at the level of spermatogonia, highly vacuolated tubules, and intratubular cell clusters.

Sonographic diagnosis of large-cell calcifying Sertoli cell tumor

Journal of Ultrasonography, 2019
Large-cell calcifying Sertoli cell tumor is a very rare neoplasm of the testis with less than 100 reported cases. It is associated with some genetic syndromes, and it has some features that help to distinguish benign and malign cases.

miR-222 Suppresses Immature Porcine Sertoli Cell Growth by Targeting the GRB10 Gene Through Inactivating the PI3K/AKT Signaling Pathway

Frontiers in Genetics, 2020
Sertoli cells are central and essential coordinators of spermatogenesis. Accumulating evidence has demonstrated that miRNAs participate in the regulation of Sertoli cell growth.

BRD9 inhibition as potential treatment option for testicular germ cell tumors

Andrology, EarlyView.
Abstract Background Testicular germ cell tumors (TGCT) are the predominant tumor in younger males. Usually, 5‐year survival rates are quite high, but 15–20% of patients with metastatic non‐seminomas are resistant to standard cisplatin‐based therapy.

Pharmacogenetics of follicle‐stimulating hormone action in the male

Andrology, EarlyView.
Abstract Male factor infertility (MFI) is involved in half of the cases of couple infertility. The follicle‐stimulating hormone (FSH) therapy is considered efficient to improve semen parameters and pregnancy rate in patients with idiopathic MFI, following the lesson learned from hypogonadotropic hypogonadism.

The role of iron in normal and impaired testicular function

Andrology, EarlyView.
Abstract Iron plays a critical role in testicular physiology, impacting spermatogenesis, testosterone production, and overall testicular function. Iron homeostasis is maintained through systemic and cellular regulatory mechanisms, including hepcidin‐mediated systemic iron control and the iron‐responsive element/iron regulatory protein (IRE/IRP) system ...

Cryptorchidism: Novel genetic insights into CCDC149 mutations

Andrology, EarlyView.
Abstract Background Cryptorchidism, characterized by the failure of one or both testes to descend into the scrotum, is a common congenital condition that can lead to infertility and increased risk of testicular cancer. CCDC149, a coiled‐coil domain‐containing protein, has been implicated in various developmental processes, but its role in the male ...

Post-Thaw Viability and Functionality of Cryopreserved Rat Fetal Brain Cells Cocultured with Sertoli Cells

Cell Transplantation, 1997
Testis-derived Sertoli cells have been used to create an immune “privileged” site outside of the testis to facilitate cell transplantation protocols for diabetes and neurodegenerative diseases.

Development of a nomogram for sperm retrieval at microTESE for idiopathic non‐obstructive azoospermia in a multi‐center cohort study

Andrology, EarlyView.
Abstract Background Non‐obstructive azoospermia (NOA) affects approximately 10% of infertile men and represents a major challenge in assisted reproductive technology (ART). A model that includes histological variants could be helpful in predicting sperm retrieval rate (SRR) after microdissection testicular sperm extraction (mTESE) in patients affected ...
