Similar morphokinetic patterns in embryos derived from obese and normoweight infertile women: a time-lapse study.
STUDY QUESTION Does female obesity affect the dynamic parameters of embryo quality assessed by time-lapse analysis? SUMMARY ANSWER Female obesity does not affect the dynamic embryo quality as determined by image acquisition and time-lapse analysis. WHAT IS KNOWN ALREADY Female obesity impairs natural and assisted reproduction but there is no agreement on the specific contribution of gametes...
متن کاملP-118: Developmental Competence of Ovine Embryos Derived from Frozen Oocytes Co-Cultured with Embryos Derived from Fresh Oocytes
Background: Currently, a limited number of studies have been done on the vitrification of small ruminant oocytes, especially in sheep, where poor developmental rates are obtained following immature and mature oocyte vitrification. Poor ovine oocyte cryopreservation could attribute to the damage to enzymes which has role in metabolic pathways. Therefore, production of cytokines and growth factor...
متن کاملThe Relationship between Cell Number, Division Behavior and Developmental Potential of Cleavage Stage Human Embryos: A Time-Lapse Study
Day 3 cleavage embryo transfer is routine in many assisted reproductive technology centers today. Embryos are usually selected according to cell number, cell symmetry and fragmentation for transfer. Many studies have showed the relationship between cell number and embryo developmental potential. However, there is limited understanding of embryo division behavior and their association with embry...
متن کاملA time-lapse photographic study of chick embryos exposed to teratogenic doses of hypoxia.
Continuous, long-term observations of amniote embryos have always been difficult. Special culture techniques for young avian and mammalian embryos have been developed (New, 1967) and these have helped to visualize the early stages of development. But studies of normal and abnormal development during the major period of organogenesis have been made largely by tedious indirect methods, such as th...
متن کاملP-110: In Vitro Developmental Competence of ICSI-Derived Activated Ovine Embryos
Background: This study was designed to respond to the controversy regarding the necessity of oocyte activation after the ICSI procedure for normal embryo development in sheep. Materials and Methods: The effect of chemical stimulation with either 5mM ionomycin (I) for 5 minutes or ionomycin + 2 mM 6-dimethylaminopurine (6-DMAP) for 3 hours on the efficiency of ICSI, was compared in six experimen...
