The effects of fertilization mode, embryo morphology at day 3, and female age on blastocyst formation and the clinical outcomes. Syst Biol Reprod Med. 2014 Sep 29;:1-7 Authors: Yin H, Jiang H, He R, Wang C, Zhu J, Luan K Abstract Abstract The aim of this study was to evaluate the influence of in vitro fertilization (IVF) versus intracytoplasmic sperm injection (ICSI), fertilization mode embryonic morphology at day 3, and female age on blastocyst development, on the clinical outcomes of pregnancy after blastocyst transfer. A total of 471 cycles were retrospectively investigated. The rates of blastocyst formation and of good blastocyst morphology were higher in IVF than in ICSI cycles but there were no significant differences in the clinical pregnancies or in the miscarriage rates. The rates of formation of blastocyst and of blastocysts with good morphology were significantly higher from good-morphology embryos than from poor-morphology embryos. Nevertheless, 16.9% of the poor-morphology embryos reached the blastocyst stage. The total rates of blastocyst formation, and rates of clinical pregnancy and implantation were statistically similar in the age 39 year groups, although tending to decrease with increasing age. When equal numbers of embryos were transferred on day 3, the rates of clinical pregnancy and implantation after blastocyst transfer were significantly higher in the 39 year age groups, which were not significantly different. The miscarriage rate...
CONCLUSIONS: While avoiding unnecessary embryo transfers and miscarriages are important goals, patients and doctors need to be aware of the high cost implications of applying PGT-A using aCGH on polar bodies. FUNDING: This research did not receive any specific grant from funding agencies in the public, commercial, or not-for-profit sectors. The ESTEEM study was funded by the European Society for Human Reproduction and Embryology. Illumina provided microarrays and other consumables necessary for aCGH testing of polar bodies.

ConclusionsAOA was able to “rescue” the poor reproductive outcomes in certain types of infertile couples with history of failure pregnancy.
CONCLUSION: MCDA twins after IVF/ICSI have lower overall survival rates and higher rates of second-trimester miscarriage compared to spontaneously conceived MCDA twins. This article is protected by copyright. All rights reserved. PMID: 31909558 [PubMed - as supplied by publisher]

ConclusionsChromosomal aberrations and aneuploidy manifested specific characteristics that differed between TEs and SA-CVBs, which indicates that distinct chromosomal abnormalities can affect certain developmental stages of embryos. Further analysis is needed to explore the chromosomal mechanisms affecting embryo development and implantation. Such information will help clinical assessments in prenatal diagnosis and reduce the incidence of genetically abnormal fetuses.
Conclusionshp-HMG and rFSH did not lead to significantly different treatment outcomes in patients with poor ovarian response undergoing in vitro fertilization/intracytoplasmic sperm injection with a gonadotropin-releasing hormone antagonist protocol, although significantly higher serum insulin-like growth factor-1 level and insignificantly lower serum insulin-like growth factor binding protein-1 level on the day of oocyte retrieval associated with hp-HMG might suggest a beneficial endocrine environment.

Conclusions: Women undergoing IVF/ICSI with a previous CS have a lower live birth rate and a higher miscarriage rate than those with a previous VD.
Authors: Yang DN, Wu JH, Geng L, Cao LJ, Zhang QJ, Luo JQ, Kallen A, Hou ZH, Qian WP, Shi Y, Xia X Abstract This meta-analysis was intended to evaluate the effects of intrauterine perfusion of peripheral blood mononuclear cells (PBMC) on the pregnancy outcomes including clinical pregnancy rates, embryo implantation rates, live birth rates and miscarriage rates of infertile women who were undergoing in vitro fertilisation (IVF) treatment. By searching Pubmed, Embase database, five articles meeting the inclusion criteria were included, and 1173 women were enrolled (intrauterine PBMC group: n = 514; NO-P...
Conclusionshp-HMG and rFSH did not lead to significantly different treatment outcomes in POR patients undergoing IVF/ISCI with a GnRH antagonist protocol, although significantly higher serum IGF-1 level and insignificantly lower serum IGFBP-1 level on the day of oocyte retrieval associated with hp-HMG might suggest a beneficial endocrine environment.
