The function of sperm is to safely transport the haploid paternal genome to the egg
containing the maternal genome. The subsequent fertilization leads to transmission of a new …

Spermiogenesis is a long process whereby haploid spermatids derived from the meiotic
divisions of spermatocytes undergo metamorphosis into spermatozoa. It is subdivided into …

Background Spermatogenesis is a complex differentiation process that involves the
successive and simultaneous execution of three different gene expression programs: mitotic …

Centrosomal proteins are necessary components of the centrosome, a conserved eukaryotic
organelle essential to the reproductive process. However, few centrosomal proteins have …

A reliable, easy to assess marker for fertility in agricultural species would be highly desirable
and Anti-Müllerian Hormone (AMH) is a promising candidate. This review summarizes …

MicroRNAs (miRNAs) are small non-coding single stranded RNA molecules that are
physiologically produced in eukaryotic cells to regulate or mostly down-regulate genes by …

Marijuana smokers and animals treated with Δ9-tetrahydrocannabinol, the principal
component of marijuana, show alterations of sperm morphology suggesting a role for …

During spermatogenesis, sperm chromatin undergoes structural changes and results in a
high condensation. This nuclear compaction would be useful as a predictor of sperm …

The discovery of a large number of long noncoding RNAs (lncRNAs), and the finding that
they may play key roles in different biological processes, have started to provide a new …

Molecular studies of meiosis in mammals have been long relegated due to some intrinsic
obstacles, namely the impossibility to reproduce the process in vitro, and the difficulty to …
