Differences among dogs in response of their spermatozoa to cryopreservation using various cooling and warming rates

Autor: Nucharin Songsasen, R.A Godke, Stanley P. Leibo, I. Yu

Publikováno v: Cryobiology. 44:62-78

Spermatozoa collected from the caudae epididymides of 16 dogs of various breeds were suspended in an isotonic salt solution (DIMI medium) containing 0.6 M glycerol, frozen in liquid nitrogen, and their "survival" was measured after thawing. In the fi

Publikováno v: Domestic Animal Endocrinology. 16:57-67

The effects of exogenous equine somatotropin (eST) administration on ovarian activity and plasma hormone levels were evaluated on horse and pony mares. The objectives of this study were to determine the effects of eST on follicular development and ci

Fertilization and early embryology: Established cell lines and their conditioned media support bovine embryo development during in-vitro culture

Autor: M.W. Myers, J.R. Broussard, Y. Menezo, S.G. Prough, J. Blackwell, R.A. Godke, J.K. Thibodeaux

Publikováno v: Human Reproduction. 9:1927-1931

These experiments were conducted to evaluate the ability of different somatic-cell monolayers or conditioned medium from somatic cells for supporting bovine embryo development in vitro. In the first experiment, bovine embryos (2- to 4-cells) were all

Comparison of the permeability properties and post-thaw motility of ejaculated and epididymal bovine spermatozoa

Autor: R.A. Godke, G. T. Gentry, M. A. Stout, Ramachandra V. Devireddy, J. Saenz, Raghava Alapati

Publikováno v: Cryobiology. 59(2)

There are very few experimental reports on the comparative water transport (membrane permeability) characteristics of ejaculated and epididymal mammalian spermatozoa during freezing. In the present study, we report the effects of cooling ejaculated a

Osmotic sensitivity of canine spermatozoa

Autor: R.A Godke, Bruce E. Eilts, Dale L. Paccamonti, S Murton, Nucharin Songsasen, I. Yu, Stanley P. Leibo

Publikováno v: Cryobiology. 44(1)

The objective of this study was to determine osmotic tolerance of canine spermatozoa. The study comprised three experiments: (1) spermatozoa suspended either in an egg yolk-citrate (EYC) extender or in Kenney skim milk extender were exposed to NaCl s

Freezing epididymal sperm from white rhinoceros (Ceratotherium simum) treated with different cryodiluents

Autor: P Bartels, R.A Godke, R.L Smith, K Lubbe

Publikováno v: Theriogenology. 51:288

The aim of this study was to evaluate the motility of White rhinoceros caudal epididymal sperm using two cryodiluents, and included the sperm viability after cold storage. Sperm morphology and motility of different fertility level bulls were evaluate
