Micronized Vaginal Progesterone Dose and Serum Progesterone Thresholds Determine Reproductive Outcomes in Frozen–Thawed Embryo Transfer With Hormone Replacement Therapy

Reproductive Medicine and Biology, Volume 25, Issue 1, January/December 2026.
ABSTRACT Purpose To evaluate the combined effects of micronized vaginal progesterone (P4) dose and achieved serum P4 levels on reproductive outcomes in hormone replacement therapy–frozen embryo transfer (HRT‐FET) cycles by classifying patients according to both parameters.

Single-cell sequencing shows mosaic aneuploidy in most human embryos

The Journal of Clinical Investigation
Mammalian preimplantation embryos often contain chromosomal defects that arose in the first divisions after fertilization and affect a subpopulation of cells — an event known as mosaic aneuploidy. In this issue of the JCI, Chavli et al.

Preimplantation Genetic Screening in In Vitro Fertilization (IVF): A Comprehensive Review of Ethical, Clinical, and Technological Developments [PDF]

Journal of Medical and Life Science
Preimplantation Genetic Testing for Aneuploidy (PGT-A) and Preimplantation Genetic Screening (PGS) have become indispensable tools in In Vitro Fertilization (IVF) to increase pregnancy rates and enhance embryo choice.

ChromInst: a multicentre evaluation of robustness in aneuploidy and structural rearrangement testing

Journal of Translational Medicine
Background Preimplantation genetic testing for aneuploidy and for chromosomal structural rearrangement (PGT-A/-SR) can improve clinical pregnancy rates and live birth rates, and shorten the time to pregnancy.

Births from aneuploid embryos: where is the evidence?

BMJ Connections. Clinical Genetics and Genomics
Background Preimplantation genetic testing for aneuploidy (PGT-A) is used principally to identify embryos with whole chromosome aneuploidy, which are generally considered non-viable. Reports of healthy live births following transfer of embryos classified

Investigating developmental characteristics of biopsied blastocysts stratified by mitochondrial copy numbers using time-lapse monitoring

Reproductive Biology and Endocrinology
Background For in vitro fertilization (IVF), mitochondrial DNA (mtDNA) levels in the trophectodermal (TE) cells of biopsied blastocysts have been suggested to be associated with the cells’ developmental potential. However, scholars have reached differing

Preimplantation genetic diagnosis

Zdravniški Vestnik, 2013
Backg round: Preimplantation genetic diagnosis (PGD) is used to analyze embryos before their transfer into uterus. It is suitable for a group of patients who are at a substantial risk of conceiving a pregnancy affected by a known genetic defect.
