Assessment of the morphometry of heads of normal sperm and sperm with the Dag defect in the semen of Duroc boars [PDF]
Journal of Veterinary Research, 2021 The Dag defect is one of the primary morphological defects in sperm correlating with reduced fertility. This defect is found in the spermatozoa of many livestock species. The aim of the study was to assess the morphometry of the heads of normal sperm and

Effect of cryopreservation on Alpaca sperm morphometry [PDF]
SPERMOVA, 2017 The objective of the study was to evaluate the effect of cryopreservation on the morphometric parameters of alpaca spermatozoa. We used six male alpacas of the Huacaya breed, between 6 to 8 years; 3 for the collection of semen by the post-copulation ...

The Relationship between Sperm Morphometry and Sperm Competition in Local Goats of Central Java, Indonesia [PDF]
Media Peternakan, 2013 The objective of this study was to examine the relationship between sperm morphometry and sperm competition in local goats. Forty bucks were used in this study, consisted of 4 breeds namely Ettawa Grade Goat (EGG), Kejobong Goat (KJG), Kacang Goat (KCG),

Genetic variation in head morphometry of rabbit sperm
Theriogenology, 2013 The aim of this study was to determine the repeatability and heritability of sperm head characteristics: width (W, μm), area (A, μm2), length (L, μm), and perimeter (P, μm), and to explore the relationships between them and with the selection objective in a rabbit paternal line selected for daily weight gain (DG, g/day) between 28 and 63 days of age ...

Dog sperm head morphometry: its diversity and evolution
Asian Journal of Andrology, 2017 Dogs have been under strong artificial selection as a consequence of their relationship with man. Differences between breeds are evident that could be reflected in seminal characteristics.

Relative testis size and sperm morphometry across mammals: no evidence for an association between sperm competition and sperm length [PDF]
Proceedings of the Royal Society of London. Series B: Biological Sciences, 2003 Understanding why there is extensive variation in sperm form and function across taxa has been a challenge because sperm are specialized cells operating at a microscopic level in a complex environment. This comparative study collates published data to determine whether the evolution of sperm morphometry (sperm total length and separate component ...

DNA fragmentation and sperm head morphometry in cat epididymal spermatozoa
Theriogenology, 2014 Sperm DNA fragmentation is an important parameter to assess sperm quality and can be a putative fertility predictor. Because the sperm head consists almost entirely of DNA, subtle differences in sperm head morphometry might be related to DNA status. Several techniques are available to analyze sperm DNA fragmentation, but they are labor-intensive and ...

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

The effect of morphometry, viscosity and liquefaction on frozen sperm quality of Ghezel ram [PDF]
Āsīb/shināsī-i Darmāngāhī-i Dāmpizishkī, 2021 The ability of sperm to move and reach the oocyte for fertilization and fertility depends on different factors such as morphometry, liquefaction and semen viscosity.
