Noneffectiveness of cryostorage duration on clinical and neonatal outcomes after single vitrified-warmed blastocyst transfers

Middle East Fertility Society Journal
Background In the current era of assisted reproductive technology, the strategy of single vitrified-warmed blastocyst transfer (SVBT) is acknowledged for positively impacting clinical outcomes and preventing the risk of multiple conceptions.

Charting Endocrine Progenitors Across Species and Organs

Advanced Science, EarlyView.
Endocrine progenitors give rise to the hormone‐producing cells of the pancreas and intestine. Using single‐cell multiomics and proteomics, this study compares these progenitors across species, systems, and organs, mapping the conserved and species‐specific gene regulatory networks that guide their formation.

Association between miscarriage rates in modified natural ovulation cycles and hormone replacement cycles during frozen-thawed embryo transfer in three IVF JAPAN GROUP fertility clinics: a retrospective analysis

Middle East Fertility Society Journal
Background Optimal endometrial preparation for frozen-thawed embryo transfer (FET) remains debated owing to conflicting results regarding outcomes in modified natural ovulation cycles (NCs) versus hormone replacement cycles (HRCs). Therefore, we aimed to

Hyaluronan Sperm Selection during ICSI (HA-ICSI) Increases Embryo Utilization in Couples with Male Factor Infertility

Fertility & Reproduction
Background: Hyaluronan (HA) sperm selection, utilizing the affinity of mature sperm for HA, has emerged as a technique to enhance the selection of sperm for intracytoplasmic sperm injection (ICSI).

A novel isolator-based system promotes viability of human embryos during laboratory processing [PDF]

, 2012
In vitro fertilisation (IVF) and related technologies are arguably the most challenging of all cell culture applications. The starting material is a single cell from which one aims to produce an embryo capable of establishing a pregnancy eventually ...

Paternal Sperm Gnas‐ICR Epigenetic Programming Contributes to PPP‐Like Phenotypes in Female Offspring

Advanced Science, EarlyView.
A paternal glucocorticoid–sperm Gnas‐ICR axis is linked to ovarian endocrine programming in female offspring. Paternal preconception caffeine exposure elevates corticosterone, promotes sperm Gnas‐ICR hypermethylation, and is associated with ovarian Gnas upregulation, cAMP/PKA/CREB–StAR activation, enhanced estradiol synthesis, and PPP‐like phenotypes ...
