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

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight. [PDF]
Exp PhysiolAbstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

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 ...

Comparable Overall Copulation Rates Yet Rank‐Biased Access to Likely Fertile Females in Male Bonobos at Wamba [PDF]
Am J Biol AnthropolABSTRACT Objectives Female bonobos (Pan paniscus) resume sexual swellings in the early postpartum stage and exhibit prolonged sexual receptivity. Despite the simultaneous availability of receptive females, genetic evidence reveals a pronounced male reproductive skew in this species.

Protein-carbohydrate interactions during fertilization [PDF]
, 1998 Interaction between gametes during fertilization is at least in part regulated by carbohydrate moieties of the zona pellucida (ZP) and carbohydrate binding proteins of the sperm surface. This review focuses on the protein-carbohydrate interactions during

Hydrodynamic propulsion of human sperm [PDF]
, 2009 The detailed fluid mechanics of sperm propulsion are fundamental to our understanding of reproduction. In this paper, we aim to model a human sperm swimming in a microscope slide chamber.

Studies on the sperm reservoir of the pig oviduct [PDF]
, 2003 During sperm transport in the female pig a proportion of spermatozoa are arrested, often for 24 h or more, in a particular segment of the utero-tubal junction (UTJ) and the adjacent tubal isthmus, where a sperm reservoir (SR) is built up.

EFFECT OF SEASON ON REPRODUCTIVE PERFORMANCES IN BUFFALO SPECIES (BUBALUS BUBALIS) [PDF]
, 2010 The importance and competitiveness of buffalo breeding in Italy, compared with the other more established forms of livestock rearing, is demonstrated by the increase in the national and world buffalo population.

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
