P-104: Embryo Sex Selection by Migration of Spermatozoa in Different Acidic pH Environment
Background: Today factors including cultural, social, religious, economic and medical such as X Linked diseases encouraged couples to choose traditional methods or new treatment for selecting the gender of child. It seems that Spermatozoa containing chromosomes X and Y have different speed in various pH. In this study the velocity of spermatozoa in different acidic pH was evaluated. Materials a...
متن کاملAn investigation of excess residual cytoplasm in human spermatozoa and its distinction from the cytoplasmic droplet
Recent studies have shown cytoplasmic droplets to be normal morphological occurrences in human male spermatozoa. When the cytoplasm around the sperm midpiece is present in large amounts, however, pathological effects may transpire. The cytoplasmic droplet then becomes known as excess residual cytoplasm, which can impair overall sperm function and produce higher levels of reactive oxygen species...
متن کاملFormation of Hydrogen Peroxide by Chilled Goat Spermatozoa and the Effects of Dead Spermatozoa on Motility Characteristics
In this study, the formation of hydrogen peroxide (H2O2) by chilled goat spermatozoa was measured. Furthermore, the effects of dead spermatozoa on motility characteristics were studied. Fresh collected ejaculates from five Shami bucks were centrifuged and virtually all seminal plasma was removed. A part of the collected spermatozoa was killed by two ways: the first by repe...
متن کاملThe cytoplasmic droplet of rat epididymal spermatozoa contains saccular elements with Golgi characteristics
The cytoplasmic droplet of epididymal spermatozoa is a small localized outpouching of cytoplasm of the tail of unknown significance. EM revealed flattened saccular elements as the near exclusive membranous component of the droplet. Light and electron microscopic immunolabeling for Golgi/TGN markers showed these saccules to be reactive for antibodies to TGN38, protein affinity-purified alpha 2,6...
متن کاملThe epididymis, cytoplasmic droplets and male fertility.
The potential of spermatozoa to become motile during post-testicular maturation, and the relationship between the cytoplasmic droplet and fertilizing capacity are reviewed. Post-testicular maturation of spermatozoa involves the autonomous induction of motility, which can occur in vivo in testes with occluded excurrent ducts and in vitro in testicular explants, and artefactual changes in morphol...
