Assessing coral sperm motility [PDF]
Scientific Reports, 2021 AbstractThe declining reproductive viability of corals threatens their ability to adapt to changing ocean conditions. It is vital that we monitor this viability quantitatively and comparatively. Computer-assisted sperm analysis (CASA) systems offer in-depth analysis used regularly for domestic and wildlife species, but not yet for coral.

Reduced glutathione and cysteine hydrochloride on crossbred bull semen [PDF]
, 2012 Over the last few years, good quality freezable semen was not utilized effectively due to less knowledge about the freezability of semen. One reason is the lack of sufficient antioxidants in the seminal plasma and semen extender.

Frontiers in Physiology, 2019 Sperm motility patterns are continuously changed after ejaculation to fertilization in the female tract. Hyperactivated motility is induced with high glucose medium in vitro or the oviduct fluids in vivo, whereas sperm maintain linear motility in the ...

WormBook, 2014 Form follows function, and this maxim holds particularly true for the nematode sperm cell. Motility is essential for fertilization, and the process of spermatogenesis culminates in the production of a crawling spermatozoon with an extended pseudopod.

PLoS ONE, 2020 Sperm motility is a crucial factor for normal fertilisation that is partly supported by mitochondrial activity. Enzymatic biofuel cells (EBFCs) generate electric currents by an electron grade from anodic to cathodic electrodes in a culture media.

Computerized Sperm Motility and Application of Sperm Cryopreservation [PDF]
Archives of Andrology, 1988 An objective method for measuring sperm motion characteristics was developed on an Intellect 100 Quantel Image Analysis System suitable for various image cytometric applications. It provided overall analysis of percent motility (% MS) as well as individual and mean measurements of motion characteristics, including vigor characteristics such as ...

Rheotaxis facilitates upstream navigation of mammalian sperm cells [PDF]
, 2014 A major puzzle in biology is how mammalian sperm maintain the correct swimming direction during various phases of the sexual reproduction process. Whilst chemotaxis may dominate near the ovum, it is unclear which cues guide spermatozoa on their long ...

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.

Semen collection and evaluation of captive coatis (Nasua nasua)
Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2012 Semen samples (n=105) were collected through eletroejaculation from six adult male coatis (Nasua nasua) between January 2007 and December 2008 at Universidade Federal de Mato Grosso Zoo, Cuiabá, Brazil. Mean values were: volume (mL); concentration (sperm/
