Assessment of aneuploidy concordance between clinical trophectoderm biopsy and blastocyst

Human Reproduction, 2018
STUDY QUESTION Is a clinical trophectoderm (TE) biopsy a suitable predictor of chromosomal aneuploidy in blastocysts? SUMMARY ANSWER In the analyzed group of blastocysts, a clinical TE biopsy was an excellent representative of blastocyst karyotype in ...

Structures and functions of cilia during vertebrate embryo development

Molecular Reproduction and Development, Volume 89, Issue 12, Page 579-596, December 2022., 2022
Abstract Cilia are hair‐like structures that project from the surface of cells. In vertebrates, most cells have an immotile primary cilium that mediates cell signaling, and some specialized cells assemble one or multiple cilia that are motile and beat synchronously to move fluids in one direction.

The Development of Nomograms to Predict Blastulation Rate Following Cycles of In Vitro Fertilization in Patients With Tubal Factor Infertility, Polycystic Ovary Syndrome, or Endometriosis

Frontiers in Endocrinology, 2021
It is well known that the transfer of embryos at the blastocyst stage is superior to the transfer of embryos at the cleavage stage in many respects. However, the rate of blastocyst formation remains low in clinical practice.

Blastocyst activation engenders transcriptome reprogram affecting X-chromosome reactivation and inflammatory trigger of implantation

Proceedings of the National Academy of Sciences of the United States of America, 2019
Significance Our data systematically and comprehensively reveal the genetic programming of blastocyst for implantation in a delayed implantation mouse model.

The effects of endocrine‐disrupting chemicals on ovarian‐ and ovulation‐related fertility outcomes

Molecular Reproduction and Development, Volume 89, Issue 12, Page 608-631, December 2022., 2022
Abstract Exposure to endocrine‐disrupting chemicals (EDCs) is unavoidable, which represents a public health concern given the ability of EDCs to target the ovary. However, there is a large gap in the knowledge about the impact of EDCs on ovarian function, including the process of ovulation.

First Baby Born in Brazil after Simultaneous Diagnosis through Non-Invasive and Conventional PGT-A

Revista Brasileira de Ginecologia e Obstetrícia, 2022
Non-invasive preimplantation genetic testing for aneuploidies (niPGT-A) aiming to assess cell-free embryonic DNA in spent culturemedia is promising, especially because it might overcome the diminished rates of implantation caused by the inadequate ...

Prostaglandins in Swine Blastocysts [PDF]

Biology of Reproduction, 1983
The activity of phospholipase A2 (PLA2) and the content of prostaglandins (PGF and PGE-A) in swine blastocysts were determined on Days 7 through 14 of gestation by using radioenzymatic and radioimmunoassay techniques. Both PLA2 activity and PG content increased in the blastocyst with age.

Blastomere movement post first cell division correlates with embryonic compaction and subsequent blastocyst formation

Reproductive Biology and Endocrinology, 2019
Background Blastomere movement (BMov) occurs after the first cell division in human embryos. This movement has been suggested as a prognostic parameter for pregnancy outcome prediction following cleavage-stage embryo transfer. However, the effect of BMov

Developmental Potential of Abnormally Fertilized Oocytes and the Associated Clinical Outcomes

Frontiers in Physiology, 2020
This study aims to investigate the embryo development potential of extending the culture of abnormally fertilized zygotes with no pronuclear (0PN), monopronuclear (1PN), and poor-quality day 3 embryos and to determine the associated clinical outcomes ...
