Viability of in vitro produced embryos of gyr cattle (bos indicus) after cryopreservation by vitrifica-tion under field conditions

open access: yesBoletim de Indústria Animal, 2016
The aim of this study was to evaluate the pregnancy rate of in vitro produced embryos of Gyr cattle (Bos indicus) after cryopreservation by the vitrification method under field conditions. Blastocysts in different developmental stages were transferred to

Hyaluronan and Hyaluronidase, which is better for embryo development? [PDF]

open access: yes, 2016
Our aim was to examine size-specific effects of Hyaluronan (HA) on preimplantation embryo development. We investigated the effects of Hyalovet (HA, 500–750 kDa; the size produced by HA synthase-3, which is abundant in the oviduct), or HA treated with ...

Does the sex ratio of singleton births after frozen single blastocyst transfer differ in relation to blastocyst development?

open access: yesReproductive Biology and Endocrinology, 2020
Purpose To investigate the associations between blastocyst development and the sex ratio (male:female) among singleton live births resulting from single-blastocyst frozen embryo transfer (FET) cycles. Methods Patients with singleton live births following

Association between transferred embryos and multiple pregnancy/live birth rate in frozen embryo transfer cycles: A retrospective study

open access: yesFrontiers in Endocrinology, 2023
BackgroundPhysicians need an appropriate embryo transfer strategy to address the challenge of reducing multiple birth rates, while maintaining the couples’ live birth rate during assisted reproductive technology.MethodsWe included 10,060 frozen embryo ...

EFFECT OF MORPHOLOGY AND BLASTOCYST DEVELOPMENT ON THE OUTCOME OF SINGLE-BLASTOCYST TRANSFER IN THE IN VITRO FERTILIZATION PROGRAMME

open access: yesZdravniški Vestnik, 2018
Background. Multiple pregnancy can be prevented by an elective single blastocyst transfer. The aim of this prospective study was to evaluate the effect of blastocyst development and morphology on the outcome of single blastocyst transfer. Methods.

Abnormal early cleavage events predict early embryo demise: sperm oxidative stress and early abnormal cleavage. [PDF]

open access: yes, 2014
Human embryos resulting from abnormal early cleavage can result in aneuploidy and failure to develop normally to the blastocyst stage. The nature of paternal influence on early embryo development has not been directly demonstrated although many studies ...

Pre-implantation mouse embryos cultured In vitro under different oxygen concentrations show altered ultrastructures [PDF]

open access: yes, 2020
Assisted Reproductive Technologies routinely utilize different culture media and oxygen (O2) concentrations to culture human embryos. Overall, embryos cultured under physiological O2 tension (5%) have improved development compared to embryos cultured ...

Live birth rate following frozen-thawed blastocyst transfer is higher in high-grade day 6 blastocysts than in low-grade day 5 blastocysts

open access: yesFrontiers in Endocrinology, 2023
BackgroundDay 5 (D5) blastocysts are generally given priority to transfer than day 6 (D6) blastocysts; however, which one should be prioritized to transfer when only low-grade D5 and high-grade D6 blastocysts are available?MethodsA large retrospective ...
