Systematic identification of Y-chromosome gene functions in mouse spermatogenesis.

Sex Chromosome Biology Laboratory, The Francis Crick Institute, London, UK.
The mammalian Y chromosome is essential for male fertility, but which Y genes regulate spermatogenesis is unresolved. We addressed this by generating 13 Y-deletant mouse models. In , , and deletants, spermatogenesis was impaired.

In recent years, bone marrow derived mesenchymal stem cells (BM-derived MSCs) have emerged as a powerful cell-based therapy for various diseases, including male infertility. Demonstrating the efficiency of BM-derived MSCs transplantation by different routes of injection to home and repair testis of busulfan-induced azoospermic rats. In the present study, rat BM-derived MSC was isolated and characterized for mesenchymal &hematopoietic markers using flow-cytometry.

The spermatozoan centrosome includes a slightly modified proximal centriole, an atypical distal centriole, and specialized pericentriolar material, including striated columns and capitellum. We investigated the localization of canonical centriolar proteins CEP44 and CCDC15 in human spermatozoa.

Background: The cryoinjury of semen during cryopreservation reduces sperm motility, constraining the application of artificial insemination (AI) in bovine reproduction. Some fertility markers, related to sperm motility before and after freezing have been identified. However, little is known about the biological mechanism through which freezing reduces sperm motility.

Clinical Institute of Genomic Medicine, University Medical Centre Ljubljana, Ljubljana, Slovenia.
Purpose: In recent years, many genes have been associated with male infertility; however, testing of monogenic forms has not yet been clinically implemented in the diagnosis of severe forms of idiopathic male infertility, as the diagnostic utility has not been established yet. The aim of this study was therefore to answer if the implementation of genetic testing for monogenic forms of male infertility could contribute to the clinical diagnosis of men with severe forms of idiopathic male infertility.
Materials And Methods: Based on the ClinGene curation protocol, we defined a panel of genes with sufficient evidence for the involvement with severe male infertility.
