This cutting method of ovarian surface becomes a good option against low responder patients. This cutting method of ovarian surface becomes a good option against low responder patients. This retrospective observational study investigated relationships between the abundance of cell-free mitochondrial DNA (cf-mtDNA) in spent culture medium (SCM) of human-expanded blastocysts and their morphokinetics to address the question of whether the abundance of cf-mtDNA in SCM could predict the quality of blastocysts. Embryos (n=53) were individually cultured in a time-lapse incubator until they reached the expanded blastocyst stage (5 or 6days), following which copy numbers of cf-mtDNA in SCM (20μL) of expanded blastocysts were determined using real-time PCR. The duration between start of blastulation to expanded blastocyst (tEB-tSB) and between that of the blastocyst stage to expanded blastocyst (tEB-tB) significantly and positively correlated with the abundance of cf-mtDNA in the SCM (tEB-tSB r=.46; <.01; tEB-tB r=.47; <.01). LY2874455 The abundance of cf-mtDNA in the SCM was significantly greater in blastocysts with blastocyst collapse (BC), than without BC, and significantly and positively correlated with the number of BC. The abundance of cf-mtDNA in the SCM was associated with expansion duration and BC. Thus, cf-mtDNA abundance in the SCM serves as a marker to predict the quality of expanded blastocysts.

We investigated the contribution of subchorionic hematoma (SCH) involvement in early pregnancy to the risk of pregnancy complications in women who underwent frozen-thawed embryo transfer (FET). A hypoechogenic area surrounding the gestational sac at early pregnancy on ultrasound was defined as SCH. Simultaneously, the presence of vaginal bleeding was evaluated. We included 1416 women with live births after FET between March 2015 and September 2018 in this study. The frequency of pregnancy complications was compared between the SCH (n=340) and non-SCH (n=1076) groups. The adjusted odds ratio of abnormal placental adhesion and placenta previa for the SCH group relative to the non-SCH group was 7.01 [2.96-18.00] and 3.77 [1.24-11.91], respectively. In contrast, hypertensive disorders of pregnancy, non-reassuring fetal status, fetal growth restriction, chorioamnionitis, and premature rupture of the membrane showed no differences between both groups. Furthermore, the frequency of abnormal placental adhesion was higher in the SCH group with vaginal bleeding than in the SCH group without vaginal bleeding. Subchorionic hematoma in early pregnancy may cause abnormal placental adhesion and placenta previa in pregnant women with FET. SCH presence should be carefully noted, particularly in cases with vaginal bleeding during early pregnancy after FET.

We aimed to evaluate how matrix metalloproteinases (MMPs) regulate the trophoblast invasion and placentation. Female rats were divided into the estrous cycle and early pregnancy day groups. Obtained uterine tissues and implantation sites were processed for immunofluorescence and real-time PCR examinations. The mRNA expression of MMP-7 was higher than MMP-2 and MMP-9. Immunofluorescence findings confirmed that MMP-2, MMP-7, and MMP-9 were localized in the endometrial stroma, while MMP-7 was high in glandular and lining epithelial cells throughout the entire estrous cycle. However, their immunolocalizations and mRNA expression
