Slow cryopreservation is not superior to vitrification in human spermatozoa; an experimental controlled study
BACKGROUND Spermatozoa cryopreservation is used for the management of infertility and some other medical conditions. The routinely applied cryopreservation technique depends on permeating cryoprotectants, whose toxic effects have raised the attention towards permeating cryoprotectants-free vitrification technique. OBJECTIVE To compare between the application of slow cryopreservation and vitri...
متن کاملA comparative study on the effects of different cryoprotectants on the quality of canine sperm during vitrification process
Cryopreservation has the capacity to extend spermatozoa’s lifespan and viability. In addition, the semen samples can be collected, preserved and stored or sent to distant locations and still be used long after the death of the semen donor. In this study for the vitrification of dog sperm (fresh and swum-up sperm), different cryopreservation mediums on the basis of glycerol, milk and egg yolk we...
متن کاملP-55: Cryopreservation of Rooster Semen Using Hand-Made Cryopreservation Media Supplemented with Different Cryoprotectants
Background Cryopreservation procedure for poultry semen is not reliable due to structural and biochemical damages which can lead to reduction in sperm quality and fertility. Development of cryopreservation medium has crucial effects for successful recovery of sperm after freezing. The objective of this study was assessment of cryopreservation of rooster semen using hand-made cryopreservation me...
متن کاملCryobiology of cephalopod (Illex coindetii) spermatophores.
Cephalopod culture is expected to increase in the near future and sperm cryopreservation would be a valuable tool to guarantee sperm availability throughout the year and to improve artificial insemination programs. We have studied the tolerance of spermatophores from the oceanic squid Illex coindetii to several cryoprotectants, in two toxicity experiments and a cryopreservation test. Five perme...
متن کاملImpact of Cryopreservation Process on Viability, Nitric Oxide and DNA Apoptosis in Fertile Human Spermatozoa
Introduction: Infertility is a common phenomenon in modern societies. Today, use of assisted reproductive technologies (ARTs) for treatment of infertility is common, and cryopreservation is one of these technologies. Cryopreservation has impact on the function and percentage of fertility of human sperm. In this study, motility, viability, nitric oxide, and DNA apoptosis were assessed before and...
