Lipofection of Non-integrative CRISPR/Cas9 Ribonucleoproteins in Male Germline Stem Cells: A Simple and Effective Knockout Tool for Germline Genome Engineering

Frontiers in Cell and Developmental Biology, 2022
Gene editing in male germline stem (GS) cells is a potent tool to study spermatogenesis and to create transgenic mice. Various engineered nucleases already demonstrated the ability to modify the genome of GS cells. However, current systems are limited by

Revised manuscript R2, clean version are serum levels of 25-hydroxy vitamin D reduced following orchiectomy in testicular cancer patients?

Basic and Clinical Andrology, 2021
Résumé Contexte Le testicule représente un lieu où le précurseur de la vitamine D est converti en sa forme active. Il a été suggéré que la perte d’un testicule pouvait induire une réduction des taux sériques de vitamine D.

Testis Development [PDF]

Endocrine Reviews, 2018
Production of sperm and androgens is the main function of the testis. This depends on normal development of both testicular somatic cells and germ cells. A genetic program initiated from the Y chromosome gene sex-determining region Y (SRY) directs somatic cell specification to Sertoli cells that orchestrate further development.

Long-Term Maintenance and Meiotic Entry of Early Germ Cells in Murine Testicular Organoids Functionalized by 3D Printed Scaffolds and Air-Medium Interface Cultivation

Frontiers in Physiology, 2021
Short-term germ cell survival and central tissue degeneration limit organoid cultures. Here, testicular organoids (TOs) were generated from two different mouse strains in 3D printed one-layer scaffolds (1LS) at the air-medium interface displaying tubule ...

Micro RNA in Semen/Urine from Non-Obstructive Azoospermia Patients as Biomarkers to Predict the Presence of Testicular Spermatozoa and Spermatogonia

Life, 2023
About half of testicular sperm extraction (TESE) procedures in men with non-obstructive azoospermia (NOA), including men with Klinefelter syndrome (KS), are unsuccessful. To avoid unnecessary invasive surgery, biomarkers for spermatozoa were studied.

Testis Cancer [PDF]

Journal of Urology, 2007
We quantified the burden of testis cancer in the United States by identifying trends in its incidence, its treatment and the use of health care resources to estimate the economic impact of the disease.The analytical methods used to generate these results were described previously.The overall incidence of testis cancer in the United States increased 46%

Transcriptomic differences between fibrotic and non-fibrotic testicular tissue reveal possible key players in Klinefelter syndrome-related testicular fibrosis

Scientific Reports, 2022
Klinefelter syndrome (KS; 47,XXY) affects 1–2 in 1000 males. Most men with KS suffer from an early germ cell loss and testicular fibrosis from puberty onwards. Mechanisms responsible for these processes remain unknown. Previous genomics studies on testis

Torsion of the appendix testis in undescended testes as a rare cause of groin swelling

Journal of Pediatric Surgery Case Reports, 2021
A 10 year-old boy presented to the emergency department with torsion of an Appendix Testis in an undescended testis. The diagnosis was suspected clinically and confirmed by ultrasound imaging. Intra-operatively, the testis was well perfused.

Does co-transplantation of mesenchymal and spermatogonial stem cells improve reproductive efficiency and safety in mice?

Stem Cell Research & Therapy, 2019
Background Spermatogonial stem cell transplantation (SSCT) is a promising therapy in restoring the fertility of childhood cancer survivors. However, the low efficiency of SSCT is a significant concern.

Supernumerary Testis

Journal of Radiology Case Reports, 2009
Polyorchidism is a rare congenital anomaly of the genital tract in which more than two testes are present, usually within the scrotum. Less than 100 cases of polyorchidism have been reported in medical literature till date. The most common form is the presence of three testis referred as triorchidism or tritestis.
