卵子冷冻保存至今已有30多年发展历史。卵子冷冻主要适用于肿瘤患者放化疗前、或非肿瘤患者和因个人因素延迟生育的人群可采用的生育力保存方式;此外还适用于因辅助生殖实施过程中,由于男方特殊的因素无法提供精子的一种补救方式。目前常用的卵子冷冻保存方式包括慢速冻存和玻璃化冻存,且随着技术的日趋成熟及对卵子保存的研究进展,玻璃化冷冻现已逐渐取代慢速程序化冷冻,成为一种成熟的生育力保存方式。目前大部分研究结果表明,使用冻存卵子与新鲜卵子进行胚胎移植,患者临床妊娠率、产科和围产期结局未见显著差异。 相似文献

Background:It is currently unknown whether patients with a fever after controlled ovulation during egg retrieval could increase the risk of pelvic infection or not, and fever itself may affect endometrial receptivity or embryo quality with poor pregnancy outcomes. The aim of this study was to analyze the outcomes of patients with fever during oocyte retrieval after the first frozen-thawed embryo transfer (FET) cycle.Methods:This was a 1:3 retrospective paired study matched for age. In this study, 58 infertility patients (Group 1) had a fever during the control ovulation, and the time of the oocyte retrieval was within 72 hours, they underwent ovum pick up and whole embryo freezing (“freeze-all” strategy). The control subjects (Group 2) are 174 patients matched for age who underwent whole embryo freezing for other reasons. The baseline characteristics, clinical data of ovarian stimulation, and outcomes, such as the clinical pregnancy rate, ongoing clinical pregnancy rate were compared between the two groups in the subsequent FET cycle.Results:All patients had no pelvic inflammatory disease after oocyte retrieval. Anti-Mullerian hormone (AMH) levels (4.2 vs. 2.2, P <0.001) were higher in group 2, and the number of oocytes retrieved, and fertilization rate were lower in group 1 (P < 0.001), but the endometrial thickness, the number of embryo transfers, and the type of luteal support supplementation were similar between the two groups. Regarding pregnancy outcomes in the subsequent FET cycle, the implantation rate, clinical pregnancy rate, early spontaneous rate, ectopic pregnancy rate, and ongoing pregnancy rate were all not significantly different. Further regression analyses showed that the clinical pregnancy rate and ongoing pregnancy rate were also not significantly different.Conclusions:Transvaginal ultrasound-guided follicular puncture for oocyte retrieval is a safe and minimally invasive method for patients with fever. Moreover, the fever had almost no effect on embryo quality. 相似文献

Oocyte and embryo grading is one of the most important steps in assisted reproductive technology to identify the best among cultured embryos for transfer or vitrification. The most commonly used non-invasive method is morphological assessment of gametes and embryos using a microscope. This method despite being simple and cost-effective has interobserver and intraobserver variability and subjectivity and has little to offer about the physiological state of embryos. This review sourced research articles and reviews pertaining to other non-invasive assessment methodologies from Medline and PubMed to collate latest technologies in vogue and identify novel methodologies of the future. The review assesses the current understanding in oocyte and embryo grading and touches upon novel non-invasive techniques and potential biomarkers to identify the best embryo. The latest available literature on time-lapse imaging, hierarchical algorithms, omics (consisting of proteomics and secretomes), miRNAs, mitochondrial RNAs and artificial intelligence has been accessed to summarize the enormous information available, to identify gaps in current interpretations, to identify emerging technologies and to provide direction for future research. This review will greatly benefit anyone practicing assisted reproduction and clinical embryology. 相似文献

目的:探讨玻璃化冷冻与慢速程序冷冻法对人未成熟卵母细胞的存活及胚胎发育潜能的影响。方法:体外受精-胚胎移植中获得的251个MⅠ期卵母细胞随机分3组,第1组94个先玻璃化冷冻保存,第2组63个先慢速程序冷冻保存,两组冻融后的未成熟卵母细胞再进行IVM,用ICSI技术对成熟卵母细胞完成授精,并进行体外胚胎培养。第3组94个MⅠ期卵母细胞先进行IVM,再进行玻璃化冷冻保存,与第1组先玻璃化冷冻保存再IVM的顺序不同,冻融后同样用ICSI技术对获得的成熟卵母细胞完成授精,并进行体外胚胎培养。结果:玻璃化冻融组复苏存活率、体外成熟率、受精率、及卵裂率均高于慢速程序冻融组(P均<0.05);先玻璃化冷冻再IVM与先IVM再玻璃化冷冻的复苏存活率、体外成熟率、可用卵比率、受精率及卵裂率无统计学意义(P均>0.05)。结论:玻璃化冻融人未成熟卵母细胞能获得更好的冷冻保存效果;玻璃化冷冻与IVM的顺序不影响未成熟卵母细胞的利用。 相似文献

Background Increasing use of fertility therapy has elicited concerns regarding adverse effects for expectant mothers and the health of
children thus conceived.
Aims To study the risk of adverse perinatal outcomes, birth defects and pregnancy complications following assisted reproductive
technology (ART).
Methods Questionnaire-based study involving 1,524 children and 1,182 pregnancies conceived following in vitro fertilisation (IVF)
in two units. Outcomes were compared with the general population.
Results In the study group versus the general population; multi-foetal gestations, 26 versus 2%; singleton preterm delivery and low
birth weight, 8.7 and 6.4 versus 4.3 and 4%, respectively; non-lethal congenital malformation rate, 2.6 versus 2.1%; placenta
praevia, 2.8 versus 0.5%.
Conclusions Multi-foetal gestations remain the principal cause of adverse perinatal outcomes after ART. Singleton ART pregnancies have
an increased risk of preterm delivery and low birth weight at term. Non-lethal congenital malformation rates are not increased
following ART. Placenta praevia is increased following ART. 相似文献
