Psychological and physiological adaptations to sperm competition in humans [PDF]
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 ...

Computational Modelling of Sperm Behaviour in a 3D Virtual Oviduct [PDF]
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

The legacy of sperm banking: how fertility monitoring and disposal of sperm are linked with views of cancer treatment [PDF]
Background: sperm banking is recommended for all men before cancer treatment, which carries a risk of long-term gonadal damage. However, relatively few men take up the offer.

Cryopreservation of common carp sperm [PDF]
Experiments were carried out to investigate the effect of five extenders (sucrose, glucose, fructose, KCl and a saline carp sperm extender) and two cryoprotectants (dimethyl-sulfoxide (DMSO) and methanol) on the cryopreservation of common carp sperm ...

Variation in sperm whale (Physeter macrocephalus) coda vocalizations and social structure in the North Atlantic Ocean [PDF]
This study aimed at complementing studies of sperm whale social and vocal behaviour that were restricted to the Pacific Ocean. The characteristic multi-pulsed structure of sperm whale clicks allows for estimation of whales' size from measurements of ...

Studies on the sperm reservoir of the pig oviduct [PDF]
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.

Sexual selection in a transparent worm : insights from fluorescent sperm [PDF]
Sexual selection is a potent source of selection underlying the evolution of sexual dimorphism, reproductive strategies and mating systems. Although sexual selection was initially thought to occur exclusively at the pre-copulatory stage (e.g., contests ...

Hydrodynamic propulsion of human sperm [PDF]
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.
