Spermatogenesis involves the processes of germ cell proliferation, meiosis, and maturation. Germ cells at different spermatogenetic developmental stages exist through out the seminiferous tubules. In cross-sections of seminiferous tubules, staging of spermatogenesis is usually performed using PAS-hematoxylin staining, however, most studies also involve immunofluorescence analysis, which can be ...

The testis has been identified as the organ in which a large number of tissue-enriched genes are present. However, a large portion of transcripts related to each stage or cell type in the testis still remains unknown. In this study, databases combined with confirmatory measurements were used to investigate testis-enriched genes, localization in the testis, developmental regulation, gene express...

Background: We are convinced that better infertility treatment will only be achieved with a better under understanding of the molecular mechanisms specific to each patient. To that effect we want to indentify genes involved in male infertility. Materials and Methods: We screened cohorts of infertile men to identify the cause of their infertility. Results: Our team has identified and caracterize...
