Effects of Different Concentratıons of Proline, Cysteine and Glutamine on Some Sperm Quality Characterıstıcs and Fertility of Cryopreserved Bee Spermatozoa (Apis Mellifera)
Development of novel cryopreservation protocols is required to test novel chemical and non-chemical supplements in freezing extender for bee semen. Antioxidants demonstrate critical effects on post-thawed sperm quality, fertility, and subsequent embryo development. The purpose of the study was to determine of the effects of different concentrations of proline, cysteine and glutamine on some sperm quality and fertility of cryopreserved bee spermatozoa.
Requirements for Cryopreservation of In Vitro-Produced Bovine Embryos by a Standard Method of Vitrification
In relation to assisted mammalian reproduction, the goal of cryopreservation is to preserve without significant loss of viability a stock of gametes and/or embryos with a view to thawing those cells for use in in vitro reproduction treatments. There are numerous cryopreservation protocols, which vary in terms of cryoprotectant used, storage temperature, freezing and thawing rates, and the particular cells that they are suitable for preserving.
Benefits and Constraints of Vitrification Technologies for Cryopreservation of Bovine In Vitro Fertilized Embryos
Cryopreservation is the use of ultra-low temperatures to preserve whole living cells and tissues in order to retain their structural
integrity and maintain their physiological viability. It enables long term storage of cells in order to circumvent the need for continuous in vitro culture. When cryopreserving bovine embryos there are two means of cryopreservation: slow programmable freezing and vitrification. While controlled-rate and slow freezing can be applied widely to in vivo derived-embryos, this methodology remains less successful for embryos produced in vitro.
