in vitro maturation (ivm) is emerging as a popular technology at the forefront of fertility treatment and preservation. however, standard in vitro culture conditions usually increase reactive oxygen species (ros), which have been implicated as one of the major causes for reduced embryonic developmental competence. it is well-known that higher than physiological levels of ros triggers granulosa ...
Background: The cryopreservation of human oocyte would make significant contribution to fertility treatments. It could also provide on alternative to embryo preservation for avoidance ethical problems. Embryo cryopreservation is now a successful procedure, but oocyte cryopreservation has poorer results. Materials and Methods: For retrieval of oocyte NMRI mouse were used. after administration of...
background: successful embryo transfer (et) technique is a fateful step of all efforts to achieve live births from in vitro produced embryos in assisted reproductive techniques or in knockout, transgenic or cloned animal projects. small reproductive tract of mice and limitation of current techniques may not well satisfy the requirements for mass production of genetically modified mice. genetic ...

INTRODUCTION The aim of this study is to report the current status of ovarian tissue cryopreservation among alternatives for fertility preservation in the Nordic countries. MATERIAL AND METHODS A questionnaire was sent to 14 Nordic academic reproductive centers with established fertility preservation programs. It covered fertility preservation cases performed up to December 2014, standard pro...
During vertebrate development, clustered genes from the Hox family of transcription factors are activated in a precise temporal and spatial sequence that follows their chromosomal order (the "Hox clock"). Recent advances in the knowledge of the underlying mechanisms reveal that the embryo uses a variety of strategies to implement this colinear process, depending on both the type and the evoluti...

The issue of fertility preservation in patients with cervical cancer is getting more and common considering the improved effectiveness early diagnosis treatment cancer. There a number evidence-based tactics available to diagnosed These have been proved effective include methods such as ovarian transposition; oocyte, embryo tissue cryopreservation. Nonetheless, there are no existing medical algo...
