Prognostic value of repeated serum kisspeptin measurements in early first trimester pregnancy: a preliminary study

ConclusionSingle serum measurement of kisspeptin is significantly altered in pregnant and non-pregnant women. However, it failed to discriminate between miscarriage and ongoing pregnancies in first-trimester pregnancy. Neither single nor sequential kisspeptin have higher diagnostic performance for miscarriage than beta-HCG in early stage.

Abstract Objective: To investigate the feasibility and clinical outcome of the all-blastocyst-culture and single blastocyst transfer strategy in women aged ≥35 years. Methods: A retrospective analysis of patients aged ≥35 years undergoing IVF/ICSI was performed from January 2017 to April 2019 in the reproductive center of the Second Affiliated Hospital of Wenzhou Medical University. A total of 155 cases treated with ovarian hyperstimulation by prolonged protocol and implemented single (84 cases) or double (71 cases) blastocyst transfer were collected. Then, patients were further divided into

This study aimed to investigate the effect of the detail type of chromosomal polymorphisms (1/9/16qh+/ −, D/G group polymorphisms, and inv(9)) on the IVF-ET outcomes.MethodsA total of 1335 infertile couples undergoing IVF/ICSI were enrolled and comprehensively analyzed the correlation between three detail types of chromosomal polymorphisms (1/9/16qh+/ −, D/G group polymorphisms, and inv(9)) and the outcome of IVF/ICSI embryo transfer. The fertilized rate, cleaved embryo rate, good-quality embryo rate, clinical pregnancy rate, implantation rate, and early stage miscarriage rate were compared between the chromoso...

ConclusionThis study concurs with the recent data suggesting that employing ICSI solely for teratospermia is unnecessary. This may allow clinics to decrease ICSI rates without sacrificing success rates, leading to lower cost and risk associated with treatment.

ConclusionWithin the limits of the small sample size, our results suggest that the aneuploidy and delivery rates of the blastocysts derived from 1PN zygotes are the same as those derived from 2PN zygotes. Blastocysts derived from 1PN zygotes may be used clinically and could increase the chance of pregnancy.

ConclusionsThe study highlights the importance of sperm quality for the efficacy of assisted reproduction treatments. This influence may remain relatively cryptic in association with normal or high ovarian response, but emerge decisively in cases of reduced ovarian response, suggesting a relationship between ovarian response and oocyte ability to compensate for paternal-derived deficiencies.

This study examined 769 patients with nonobstructive azoospermia who underwent 347 cycles of micro-TESE-ICSI. Patients with azoospermia were classified into Group A (Klinefelter syndrome, n = 284, 125 cycles), Group B (azoospermia Y chromosome factor c [AZFc] microdeletion, n = 91, 64 cycles), Group C (cryptorchidism, n = 52, 39 cycles), Group D (previous mumps and bilateral orchitis, n = 23, 23 cycles), and Group E (idiopathic azoospermia, n = 319, 96 cycles). Clinical characteristics, SRR, embryonic development, and pregnancy outcomes of the patients were compared between all groups. Patients in Group D had the highest a...

CONCLUSIONS: The current evidence from randomised controlled trials does not support or refute the clinical use of intracytoplasmic sperm injection (intracytoplasmic morphologically selected sperm injection (IMSI). We are very uncertain of the chances of having a live birth and of the risk of having a miscarriage. We found very low-quality evidence that IMSI may increase chances of a clinical pregnancy, which means that we are still very uncertain about any real difference. We did not find any trials reporting on the risk of congenital abnormalities. Well-designed and sufficiently powered trials are still required. PM...

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.
