Sperm biology and male reproductive health

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.
