Commercial embryo transfer has evolved as an art and as a science since the early 1970s. Today's multiple ovulation embryo transfer is a widely used reproductive tool on many farms and is performed by veterinarians throughout the world. Propagation of the female genomes of select donors, through embryo transfer, has allowed a rapid progression of genetic gain in many breeds, much like what happened with artificial insemination since the 1940s. Advancement of this technology is migrating to in vitro fertilization technology today, allowing a higher volume of offspring to be produced with sex selection in the laboratory.

Purpose: To examine the association between blastocyst morphology and chromosomal status utilizing pre-implantation genetic testing for aneuploidy (PGT-A).
Methods: A single-center retrospective cohort study including 169 in-vitro fertilization cycles that underwent PGT-A using Next Generation Sequencing (2017-2022). Blastocysts were morphologically scored based on Gardner and Schoolcraft's criteria.

The research question is as follows: Are estrogen and progesterone receptor genotypes associated with thin endometrium? We performed a prospective cohort study of 129 patients who underwent preimplantation genetic testing for aneuploidies. These patients were categorized according to endometrial thickness: >7 mm control group (n = 94) and ≤7 mm study group (n = 35). Polymorphisms in the genes ESR1 (rs9340799 and rs3138774), ESR2 (rs1256049 and rs4986938), and PGR (rs1042838) were analyzed.

Background: Growth hormone (GH) could improve the outcomes of fertilization and embryo transfer (IVF-ET) in patients with decreased ovarian reserve (DOR), but which age group will benefit the most has remained controversial. This study aims to explore the outcome of IVF-ET among differently aged patients with DOR treated with GH.
Methods: A total of 846 patients with DOR undergoing IVF-ET from May 2018 to June 2023 at the Reproductive Medicine Center of Sichuan Provincial Women's and Children's Hospital were prospectively enrolled.

Background: Thin endometrial thickness (EMT) and advanced age are both common risk factors for adverse neonatal outcomes (ANOs). However, studies evaluating the impact of EMT and combined effect of EMT and age on ANOs remain scarce with conflicts.
Method: A retrospective cohort study was conducted on 7,715 singleton deliveries from frozen embryo transfer (FET) cycles between 2017 and 2021.

Intramural pregnancy (IMP) is an extremely rare form of ectopic pregnancy (EP), typically associated with previous uterine trauma, adenomyosis, or assisted reproductive technology (ART), such as embryo transfer (ET). Despite its potentially life-threatening nature, the absence of definitive preoperative diagnostic criteria for IMP complicates its early detection and management, especially in patients without known risk factors. Additionally, management becomes more challenging when there is an elevated risk of hemorrhage.
