Noninferiority, randomized, controlled trial comparing embryo development using media developed for sequential or undisturbed culture in a time-lapse setup.
OBJECTIVE To study whether a culture medium that allows undisturbed culture supports human embryo development to the blastocyst stage equivalently to a well-established sequential media. DESIGN Randomized, double-blinded sibling trial. SETTING Independent in vitro fertilization (IVF) clinics. PATIENT(S) One hundred twenty-eight patients, with 1,356 zygotes randomized into two study arms. ...
متن کاملEvaluation of human embryo development in in vitro fertilization- and intracytoplasmic sperm injection-fertilized oocytes: A time-lapse study
OBJECTIVE We investigated whether the insemination method (in vitro fertilization [IVF] or intracytoplasmic sperm injection [ICSI]) affected morphokinetic events and abnormal cleavage events in embryonic development. METHODS A total of 1,830 normal fertilized embryos were obtained from 272 IVF and ICSI cycles that underwent ovum retrieval culture using a time-lapse system (Embryoscope) from J...
متن کاملEmbryo development of fresh ‘versus’ vitrified metaphase II oocytes after ICSI: a prospective randomized sibling-oocyte study
BACKGROUND A successful oocyte cryopreservation programme is of utmost importance where a limited number of oocytes can be inseminated per cycle, to overcome legal and ethical issues related to embryo storage, for oocyte donation programmes and for fertility preservation (especially for cancer patients). Vitrification has been recently proposed as an effective procedure for this purpose. METH...
متن کاملFertilization and Embryo Development of Fresh and Cryopreserved Sibling Oocytes
Background The pattern of Islamic fasting differs from other forms of fasting, therefore its effect on health also differs. This research studies the effect of Islamic fasting on gonadotropin hormones around the time of the ovulatory cycle and ovulation. MaterialsAndMethods This self-controlled study was performed on 24 adult females. Blood sampling was performed during Ramadan and two months l...
متن کاملEarly embryo development in a sequential versus single medium: a randomized study
BACKGROUND The success of in vitro fertilization techniques is defined by multiple factors including embryo culture conditions, related to the composition of the culture medium. In view of the lack of solid scientific data and in view of the current general belief that sequential media are superior to single media, the aim of this randomized study was to compare the embryo quality in two types ...
