Summary
Embryologists in Latin America use varied blastocyst classification systems. However, a majority favor unifying embryo scoring regionally to improve assisted reproduction outcomes.
Area of Science:
- Reproductive Medicine
- Embryology
Background:
- Blastocyst grading is crucial for assisted reproduction outcomes.
- Standardization of blastocyst classification systems is lacking in Latin America.
Purpose of the Study:
- To identify current blastocyst classification systems used by embryologists in Latin America.
- To assess the feasibility of establishing a regional consensus on blastocyst grading.
Main Methods:
- An email survey was distributed via the Latin American Network of Assisted Reproduction (REDLARA).
- The survey targeted embryologists from assisted reproduction centers across Latin American countries.
Main Results:
- Sixty surveys were collected from 12 Latin American countries.
- Seven distinct blastocyst classification systems were reported, with five previously described in literature.
- 66.7% of respondents had over 10 years of professional experience.
Conclusions:
- Despite the diversity in blastocyst classification systems, a consensus exists among surveyed embryologists.
- The majority support unifying embryo scoring systems within their countries and the wider region.

01:33Cleavage and Blastulation
50.7K
After a large-single-celled zygote is produced via fertilization, the process of cleavage occurs while zygotes travel through the uterine tube. Cleavage is a mitotic cell division that does not result in growth. With each round of successive cell division, daughter cells get increasingly smaller.

1.4K
Classification is the process of organizing organisms into hierarchically inclusive groups based on their phenotypic similarities or evolutionary relationships. A species comprises one or more strains, and closely related species are grouped into genera. Genera are further classified into families, families into orders, orders into classes, and so forth, up to the domain level, which is the broadest taxonomic rank derived from a combination of phenotypic and genotypic data.The nomenclature of...

1.1K
In vitro fertilization (IVF) is a form of assisted reproductive technology where an egg is fertilized with sperm in a controlled laboratory environment before transferring the resulting embryo into the uterus. This process is designed to help individuals and couples experiencing difficulties conceiving.
The IVF process begins with ovarian stimulation, during which reproductive endocrinologists prescribe hormonal medications to stimulate the ovaries to produce multiple eggs instead of the single...

Gastrulation establishes the three primary tissues of an embryo: the ectoderm, mesoderm, and endoderm. This developmental process relies on a series of intricate cellular movements, which in humans transforms a flat, “bilaminar disc” composed of two cell sheets into a three-tiered structure. In the resulting embryo, the endoderm serves as the bottom layer, and stacked directly above it is the intermediate mesoderm, and then the uppermost ectoderm. Respectively, these tissue strata...
