Andrology, EarlyView.ABSTRACT Background A large number of children have been born using testicular sperm from men with Klinefelter syndrome (KS), whereas reports of children conceived using ejaculated sperm are rare. Objective To review all published cases of children conceived using ejaculated sperm from men with KS, assess their health and karyotype, and evaluate ...

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.

MAX controls meiotic entry in sexually undifferentiated germ cells
Scientific ReportsMeiosis is a specialized type of cell division that occurs physiologically only in germ cells. We previously demonstrated that MYC-associated factor X (MAX) blocks the ectopic onset of meiosis in embryonic and germline stem cells in culture systems. Here,

Andrology, EarlyView.ABSTRACT Background Mammalian sperm head morphology varies across species and dictates fertilization capability. Rodent sperm have asymmetric, hook‐shaped heads, complicating analysis. Despite widespread biomedical use, current tools poorly characterize these complex variations.

, 2017 In Drosophila males, there is no synaptonemal complex and recombination does not occur. Thus, Drosophila male meiosis is a good model system for the analysis of achiasmate chromosome segregation. In addition, due to their large size, the meiotic spindles

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 ...
