Computational Modelling of Sperm Behaviour in a 3D Virtual Oviduct [PDF]
, 2011 The processes by which individual sperm cells navigate the length and complexity of the female reproductive tract and then reach and fertilise the oocyte are fascinating. Numerous complex processes potentially influence the movement of spermatozoa within

Psychological and physiological adaptations to sperm competition in humans [PDF]
, 2005 Postcopulatory competition between males, in the form of sperm competition, is a widespread phenomenon in many animal species. The extent to which sperm competition has been an important selective pressure during human evolution remains controversial ...

Size dependent inhibition of sperm motility by copper particles as a path towards reversible male contraception [PDF]
, 2021 Effective inhibition of sperm motility using a spermicide can be a promising approach in developing non-invasive male contraceptive agents. Copper is known to have contraceptive properties and has been used clinically for decades as intrauterine ...

Plasma membrane Ca2+ ATPase 4 is required for sperm motility and male fertility [PDF]
, 2004 Calcium and Ca(2+)-dependent signals play a crucial role in sperm motility and mammalian fertilization, but the molecules and mechanisms underlying these Ca(2+)-dependent pathways are incompletely understood. Here we show that homozygous male mice with a

Post-Meiotic Intra-Testicular Sperm Senescence in a Wild Vertebrate [PDF]
, 2012 There is growing interest in sperm senescence, both in its underlying mechanisms and evolutionary consequences, because it can impact the evolution of numerous life history traits. Previous studies have documented various types of sperm senescence, but
