Colloid Centrifugation of Semen: Applications in Assisted Reproduction
Colloid centrifugation can be used to separate heterogeneous populations of cells particularly semen samples, which typically contain mixtures of spermatozoa at different stage of maturity together with dead and dying spermatozoa and also non-sperm cells. Colloids can be used to enrich the population of spermatozoa that are viable and functional; these are the spermatozoa that are needed for fe...
متن کاملMotility and recovery of alpaca (Vicugna pacos) spermatozoa after centrifugation in a density gradient solution
Background: One of the factors limiting successful processing of alpaca (Vicugna pacos) semen is the viscosity of seminal plasma. The viscous nature of the collected ejaculate has hindered sperm cryopreservation as well as artificial insemination (AI) under field conditions. Aims: The objective of this investigation was to evaluate recovery, motility, ...
متن کاملSperm Characteristics in Cryopreserved Buffalo Bull Semen and Field Fertility
Semen quality and its relationship to fertility are major concern in animal production. The aim of this study was to assess the relationship between frozen thawed sperm characteristics and fertility following in vivo fertility through Artificial Insemination(AI). Semen samples were collected from four buffalo bulls. Semen volume and sperm concentration appeared to be significantly different (P0...
متن کاملCryocapacitation and Fertility of Cryopreserved Semen
Cryopreservation of semen is the most widely applied reproductive biotechnological tool used for rapid genetic improvement of livestock through artificial insemination, but the process of cryopreservation and thawing inflicts certain damage to spermatozoa plasma membrane and acrosome. This damage includes swelling and breakage of plasma membrane, loss of membrane selective permeability, change ...
متن کاملStallion Sperm Selection by Density Gradient CentrifugationInvolving a Double Layer Colloid: Effects on Sperm Subpopulation Dynamics in Fresh and Stored Semen
Sperm selection techniques have became an important tool to improve sub fertile ejaculates. The main aim of this study was to assess the dynamics of motile sperm subpopulations of ejaculates from subfertile stallions subjected to density gradient centrifugation (DGC) involving a double layer colloid [DGC2], before and after storage for 24 and 48 hours. Ejaculates from eight stallions with ferti...
