Cryopreservation of sperm, embryos and, more recently, oocytes plays an important and
increasing role in assisted reproduction, due to improvements of old, and introduction of new …

This review summarizes pertinent data and opinions regarding the potential hazard of
disease transmission through cryopreserved and banked embryos in liquid nitrogen (LN) …

The ability to transfer frozen embryos directly to recipient females after thawing would be a
convenience in embryo transfer and would facilitate marketing embryos produced in large …

OBJECTIVE: To describe several fundamental variables that influence ultimate survival of
oocytes and embryos when they are cryopreserved. DESIGN: The literature describing …

Different methods for the cryopreservation of ovine embryos were evaluated in vitro (survival
upon culture in vitro) and in vivo (pregnancy and lambing rates after transfer in field …

Computer-assisted sperm analyzers (CASA) have become the standard tool for evaluating
sperm motility because they provide objective results for thousands of mammalian …

Cryopreservation of sheep embryos with ethylene glycol as a protectant appears to be more
effective than glycerol, particularly at the morula stage, as has been demonstrated on the …

Equine embryos (n= 43) were recovered nonsurgically 7–8 days after ovulation and
randomly assigned to be cryopreserved in one of two cryoprotectants: 48%(15M) methanol …

The survival of ovine embryos (morulae and blastocysts) either frozen by a conventional
method or vitrified was investigated in culture. In Experiment I, embryos were vitrified using a …

In this study, we applied proton NMR to measure the permeation of two cryoprotective
agents (CPAs), ethylene glycol (EG) and methanol, into 1st instar Anopheles larvae …
