Preimplantation genetic diagnosis (PGD) was first reported in 1990. Thereafter, more and more indications for PGD, including monogenic diseases (MGD) and translocations, are presently available, and the list of indications of PGD is expanding from early-onset and serious conditions to late-onset diseases. Polymerase chain reaction has been used for PGD of MGD, while newer techniques, including karyomapping and next-generation sequencing, emerge in recent decade. The limitations of various methods for PGD are discussed in this review.

Context: Progestins have recently been used as an alternative for gonadotropin-releasing hormone (GnRH) analogues to prevent premature luteinizing hormone surge due to the application of vitrification technology. However, the long-term efficacy and safety of a progestin-primed ovarian stimulation (PPOS) regimen, including oocyte competence, cumulative live birth rate (LBR), and offspring outcomes, remain to be investigated.
Objective: To compare cumulative LBR of preimplantation genetic testing (PGT) cycles between a PPOS regimen and GnRH analogues.

Background: Hereditary nephropathy is an important cause of renal insufficiency and end-stage renal disease. Therefore, for couples with monogenic nephropathy, preventing transmission of the disease to offspring is urgent. Preimplantation genetic testing for monogenic disorders (PGT-M) is a means to prevent intergenerational inheritance by screening and transplanting normal embryos.

3-methyl-4-nitrophenol (PNMC), a chemical prevalent in various industries for drug, dye, and leather production, also serves as a primary byproduct of organophosphate insecticides. Despite its global recognition as an endocrine disruptor with documented reproductive toxicity, its detrimental impact on preimplantation embryonic development has yet to be thoroughly investigated. In this study, through the in vitro culture of mice embryos, it was initially observed that even low concentrations of PNMC exposure led to a significant reduction in blastocyst formation and a sharp decline in the ratio of inner cell mass within the blastocysts.

: To assess the ploidy status of embryos via preimplantation genetic testing for aneuploidy (PGT-A), a biopsy of trophectoderm (TE) cells can be performed. However, this approach is considered invasive, and therefore the aim of this study was to identify the optimal sample type and sampling day for non-invasive or minimally invasive PGT-A (ni/miPGT-A) in terms of data quality and concordance rates with TE biopsies derived from the same embryos. : This study was performed using 239 embryo cultures.
