The implantation of embryo depends on the quality of the embryo and the receptivity of the endometrium. While the factors affecting embryo quality were optimized, the implantation rates did not reach the desirable levels. This directs the blaming for endometrial receptivity which already has been affected by supra-physiological levels of hormone, namely estradiol, in controlled ovarian hypersti...
Introduction The cryoconservation of pig embryos with intact zona pellucida would be a major advantage to control and then insure minimal risk of disease transmission during embryo transfer of genetic material. Moreover, international rules on embryo transport outside of the country origin require that only embryos with an intact zona pellucida may be exported [9]. A vitrification technique is ...
embryo transfer (et) in holstein dairy cattle became an important commercial enterprise after the introduction of non-surgical recovery technique. embryo transfer could increase the reproductive rate of genetically superior cows. the objectives of the present study were to evaluate the use of et in iranian holstein dairy cattle to increase selection intensity on the dam side, economically; esti...
BACKGROUND Single embryo transfer (particularly of a top quality embryo) is an excellent model to correlate embryo quality in terms of morphological criteria to early pregnancy. We investigated whether this model could provide us with more information on what happens after implantation in the first trimester of pregnancy. METHODS The outcome of 370 consecutive single top quality embryo transf...
The success rate after treatment by in-vitro fertilization (IVF) depends on the characteristics of the couples being treated, and the performance of the clinic. The former cannot be changed, and embryology laboratories have worked hard to optimize procedures. Numerous studies have been reported on how to improve insemination and culture procedures. The clinicians' role is confined to stimulatio...
OBJECTIVE To compare the effectiveness of elective single embryo transfer versus double embryo transfer on the outcomes of live birth, multiple live birth, miscarriage, preterm birth, term singleton birth, and low birth weight after fresh embryo transfer, and on the outcomes of cumulative live birth and multiple live birth after fresh and frozen embryo transfers. DESIGN One stage meta-analysi...
BACKGROUND Improvement of assisted reproductive technique (ART) results in higher pregnancy rates from positive Beta HCG to take home baby statistics. Despite developments in culture media allowing blastocyst stage transfer, some centers apply second, third and sometimes fourth day post injection for embryo transfer. This study aimed to compare their reproductive outcomes. METHODS This prospe...
