Frozen-thawed cleavage stage versus blastocyst stage embryo transfer in high responder patients.

Frozen-thawed cleavage stage versus blastocyst stage embryo transfer in high responder patients. Zygote. 2020 Aug 27;:1-5 Authors: Eftekhar M, Mohammadi B, Tabibnejad N, Mortazavi Lahijani M Abstract Clinical outcomes following frozen-thawed cleavage embryo transfer versus frozen-thawed blastocyst transfer in high responder patients undergoing in vitro fertilisation/intracytoplasmic sperm injection cycles are still debated. In a retrospective study, 106 high responder patients who were candidate for 'freeze-all embryos' were recruited. Frozen-thawed embryos were transferred at the cleavage stage (n = 53) or the blastocyst stage (n = 53). Clinical pregnancy was considered as the primary outcome and chemical pregnancy, ongoing pregnancy, implantation rate, and fertilization rate, as well as miscarriage rate, were measured as the secondary outcome. Clinical (47.2% vs. 24.5%), chemical (56.6% vs. 32.1%), and ongoing pregnancy rates (37.7% vs. 17%) as well as implantation rates (33.6% vs. 13.5%) were significantly higher in the blastocyst group compared with the cleavage group respectively (P 0.05). Transfer of frozen-thawed embryos at the blastocyst stage was preferable in the high responder patients to increase implantation, pregnancy and live birth rates compared with cleavage stage embryo transfer.

CONCLUSIONS: There is insufficient good-quality evidence of a difference in cumulative live birth rate, live birth rate after the first embryo transfer, or miscarriage rate between IVF with and IVF without PGT-A as currently performed. No data were available on ongoing pregnancy rates. The effect of PGT-A on clinical pregnancy rate is uncertain. Women need to be aware that it is uncertain whether PGT-A with the use of genome-wide analyses is an effective addition to IVF, especially in view of the invasiveness and costs involved in PGT-A. PGT-A using FISH for the genetic analysis is probably harmful. The currently available...

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...

CONCLUSIONS: This review raises important questions regarding the merit of long-term GnRH agonist therapy compared to no pretreatment prior to standard IVF/ICSI in women with endometriosis. Contrary to previous findings, we are uncertain as to whether long-term GnRH agonist therapy impacts on the live birth rate or indeed the complication rate compared to standard IVF/ICSI. Further, we are uncertain whether this intervention impacts on the clinical pregnancy rate, multiple pregnancy rate, miscarriage rate, mean number of oocytes and mean number of embryos. In light of the paucity and very low quality of existing data, part...

CONCLUSIONS: This review evaluated different temperatures for embryo culture during IVF. There is a lack of evidence for the majority of outcomes in this review. Based on very low-quality evidence, we are uncertain if incubating at a lower temperature than 37°C improves pregnancy outcomes. More RCTs are needed for comparing different temperatures of embryo culture which require reporting of clinical outcomes as live birth, miscarriage, clinical pregnancy and adverse events.

CONCLUSIONS: The evidence suggests that sperm selected by hyaluronic acid binding may have little or no effect on live birth or clinical pregnancy but may reduce miscarriage. We are uncertain of the effect of Zeta sperm selection on live birth, clinical pregnancy, and miscarriage due principally to the very low quality of the evidence for this intervention. We are uncertain of the effect of the other selection techniques on live birth, miscarriage, or pregnancy.Further high-quality studies, including the awaited data from the identified ongoing studies, are required to evaluate whether any of these advanced sperm selection...

Abstract BACKGROUND: Observational studies suggest higher pregnancy rates after the hysteroscopic removal of endometrial polyps, submucous fibroids, uterine septum or intrauterine adhesions, which are present in 10% to 15% of women seeking treatment for subfertility. OBJECTIVES: To assess the effects of the hysteroscopic removal of endometrial polyps, submucous fibroids, uterine septum or intrauterine adhesions suspected on ultrasound, hysterosalpingography, diagnostic hysteroscopy or any combination of these methods in women with otherwise unexplained subfertility or prior to intrauterine insemination (IUI),...

CONCLUSIONS: Though promising data on the in vitro maturation (IVM) technique have been published, unfortunately there is still no evidence from properly conducted randomised controlled trials upon which to base any practice recommendations regarding IVM before in vitro fertilisation (IVF) or intracytoplasmic sperm injection for women with polycystic ovarian syndrome. Regarding our secondary outcomes, very low-quality evidence showed that clinical pregnancy was higher with IVM when compared to IVF, whereas the incidence of ovarian hyperstimulation syndrome was zero in both studies in both groups. We are awaiting the result...
