Background: To explore and compare the dual embryo transfer DET with single embryo transfer SET weather electively or not, in more viewpoints like financially, and scientifically and finding out which of these policies may give better outcome by analyzing both in a neutral broad spectrum manner. Materials and Methods: A computerized comprehensive search studies ended in finding of 62 articles o...

Abstract Study question Is a change of embryo quality through vitrification and thawing associated with reduced LBR when single euploid frozen transfer is performed? Summary answer Live birth rates are not influenced by in cryopreservation transfer. What known already Embryo aneuploidy the most significant factor accounts for about 50% implantation failure miscarriage human reproduction. Preimp...

To evaluate whether duration of autologous oocyte vitrification has an impact on in-vitro fertilization (IVF) cumulative live birth rates (cLBR) after fresh or frozen embryo transfers. We identified IVF cycles using vitrified/thawed oocytes from 2010-2020. Ovarian stimulation, vitrification/thawing, IVF/ICSI, culture/transfer were performed published protocols. Duration cryopreservation for the...

A slow freezing/rapid thawing method for the cryopreservation of human oocytes has been employed using a sodium-depleted culture media. In 53 frozen egg-embryo transfer (FEET) cycles, a 60.4% survival rate post-thaw was obtained and a 62.0% fertilization rate following intracytoplasmic sperm injection. Overall pregnancy rates were 26.4% per thaw attempt, 30.4% per patient, and 32.6% per embryo ...

BackgroundThe number of frozen Embryo transfers (FET) in invitro fertilization cycles (IVF) is increasing and has already surpassed numbers fresh stimulated IVF cycles. Increasing elective single ETs are also resulting more embryos available for subsequent FET Most commonly, medicated or hormone supplemented (HC) which the endometrium prepared by exogenous estrogen progesterone following pituit...

OBJECTIVE To review utilisation of elective embryo cryopreservation in the expectant management of patients at risk for developing ovarian hyperstimulation syndrome (OHSS), and report on reproductive outcome following transfer of thawed embryos. MATERIALS AND METHODS Medical records were reviewed for patients undergoing IVF from 2000-2008 to identify cases at risk for OHSS where cryopreservat...

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 ...

BACKGROUND In couples presenting with retrograde ejaculation refractory to medical treatment, the first choice of fertility treatment should be Assisted Reproductive Techniques using rapidly purified spermatozoa retrieved from post-ejaculatory urine. The Hotchkiss technique and modified variants are simple and efficient for retrieving sperm from the bladder. We developed a new protocol, includi...

A total of 364 consecutive patients requesting in-vitro fertilization (IVF) treatment were divided randomly into two groups. In the first group, two embryos in the original IVF cycle were allowed to divide prior to transfer, with any remaining embryos being cryopreserved at the pronucleate (PN) stage. In the second group, all the embryos were allowed to divide to the early cleavage (EC) stage, ...

Abstract Study question Is patient usage of transdermal estradiol more effective than oral on endometrial preparation in frozen-thawed embryo transfer cycles? Summary answer This study showed no significant differences clinical pregnancy rates between the 2 groups. Transdermal gel have advantage better comfort, lesser side effects. What is known already Estrogen and progesterone are crucial fac...
