    A male factor is detected in about half of infertile couples seeking medical assistance to achieve pregnancy. A number of clinical conditions and lifestyle factors can affect male fertility through alterations to spermatogenesis, sperm function, and endocrine profiles. This Collection gathers research Articles investigating sperm functional integrity and seminal plasma molecular pathways. Submissions are also welcome that consider the physiopathology and clinical aspects of male infertility.

    There have been increasingly lively discussions about many published scientific results failing validation by independent studies. This so-called reproducibility crisis has led to criticisms of study design in animal research. Inappropriate statistical methods, poor experimental design, and extreme standardization in trial design may contribute to the problem. The purpose of this Collection is to present original methodologies to improve the status quo and to report meta-research about the reproducibility of published animal research.
