Balanced reciprocal translocations are the most common structural abnormalities; most involve two autosomes while a few involve a gonosome (X or Y chromosome) and an autosome. These rearrangements are usually associated with infertility and/or a higher risk of chromosomal imbalances among offspring. This 26 years old man was first seen because of a 3-year(More)
A medium containing LDL (Low Density Lipoproteins, the cryoprotective component of chicken egg yolk) was compared with egg yolk for the preservation canine spermatozoa during the freeze-thaw process. Twenty sperm samples taken from 10 dogs were frozen in liquid nitrogen at -196 degrees C in seven different media: one control medium containing 20% egg yolk,(More)
Twenty sperm samples from five dogs were frozen in liquid nitrogen at -196 degrees C in 16 different media, two control media containing 20% egg yolk and 6% low-density lipoproteins (LDL); 10 test media containing 6% LDL (the active cryoprotective ingredient of chicken egg yolk) combined with 10, 20, 30, 40, 50, 60, 70, 80, 90, and 100 mmol of glutamine(More)
The objective of this study was to evaluate the effects of a combination of 6% low-density lipoproteins (LDL) and 20 mm glutamine in comparison with other extenders used for the refrigeration of canine semen: Tris egg yolk (EY) 20% and 6% LDL. The percentages of mobile spermatozoa after 4 days storage in a domestic refrigerator at +4 °C were 53.1%, 44.2%(More)
