The objective of this study was to evaluate the effects of different maturation systems on oocyte resistance after vitrification and on the phospholipid profile of the oocyte plasma membrane (PM). Four different maturation systems were tested: 1) in vitro maturation using immature oocytes aspirated from slaughterhouse ovaries (CONT; n = 136); 2) in vitro maturation using immature oocytes obtain...
Prevalence of Polycystic Ovarian Syndrome(PCOS) in Iran is more than 6%. Therefore we encounter with many PCOS patients. In Vitro Maturation (IVM) of oocytes as an attractive method in ART is considered. Studies show that changes in culture conditions should be administered to make IVM protocol more successful .For this purpose in this study we have set up the beneficial cultures for IVM proced...
A study was conducted opportunistically to evaluate the potential of rescuing immature oocytes from the ovaries of the Sumatran rhinoceros postmortem. Recovered oocytes (n = 30) were placed in maturation culture for 36 hr and inseminated with frozen-thawed homologous spermatozoa. After culture, evaluation of nuclear maturation status revealed that a large number of oocytes were degenerated (n =...
the purpose of this study was to evaluate the use of glass capillary micropipette (gcm) as a vessel forvitrification of bovine oocytes. cumulus-oocyte complexes (cocs) were obtained from slaughter-house andwashed 5 to 6 times in the washing medium (tcm-199 + 20% fbs) and randomly assigned to treatment andcontrol group. in the first step of vitrification, cocs were exposed to first vitrification...
