Spermatozoa from male mice with infertility due to Odf4 deficiency can fertilize oocytes by in vitro fertilization

Reproductive Medicine and Biology
Purpose The purpose of this study is to confirm whether in vitro fertilization (IVF) with spermatozoa from Odf4‐deficient infertile males (Odf4−/− spermatozoa) can lead to the development of zygotes, which was reported in a previous in vivo study ...

Improvement of Mouse Spermatozoa Freezing at ‐80°C With Ascorbic Acid 2‐Glucoside at Thawing Phase

Andrology, EarlyView.
ABSTRACT Background Sperm cryopreservation is the most common method to maintain a great number of mutant mouse lines. However, the use of liquid nitrogen (LN2) for freezing presents considerable problems in terms of cost, safety, and accessibility. For this reason, the storage of semen samples at ‐80° in ultra‐freezers has been increasingly used in ...

Hyperactivation and Tyrosine Phosphorylation of Cryopreserved Stallion Spermatozoa in Relation to Conventional In Vitro Fertilization Blastocyst Production

Andrology, EarlyView.
ABSTRACT Background Challenges in establishing clinical conventional in vitro fertilization (IVF) in horses include variation in sperm and oocyte quality, which can be affected by mare age. Extended preincubation of stallion spermatozoa has resulted in successful IVF.

Prediction of preterm birth using 3D volume cesarean scar morphology in pregnant women with previous advanced labor cesarean delivery

Acta Obstetricia et Gynecologica Scandinavica, EarlyView.
Ultrasound assessment of the scar distance to the internal os may be considered as part of spontaneous preterm birth risk stratification in women with advanced labor cesarean delivery. Abstract Introduction This study aimed to develop a multiparameter predictive model for spontaneous preterm birth in pregnant women with a history of advanced labor ...

Does synchronising follicular wave emergence improve outcomes in non‐superstimulated donor cattle undergoing ovum pick‐up (OPU) for in vitro embryo production?

Australian Veterinary Journal, EarlyView.
In vitro embryo production (IVEP) is now a widely commercialised assisted reproductive technology used in cattle reproduction. The use of follicle‐stimulating hormone (FSH) to superstimulate donor cattle prior to ovum pick‐up (OPU) is generally regarded as an effective strategy to improve oocyte quality, developmental competence and increase embryo ...

Mechanistic Insights Into Recurrent Implantation Failure: The Lactate–H3K18la–SLC7A11 Axis Explored via Endometrial Organoid and Blastoid–Endometrial Cell Implantation Models

Cell Proliferation, EarlyView.
Clinical samples first revealed impaired lactate synthesis in RIF patients. Subsequently, using endometrial organoids and a blastoid‐endometrial cell implantation model, we demonstrated that lactate enhances endometrial receptivity via H3K18la‐mediated SLC7A11 activation.

Establishment of Human Formative Pluripotent Stem Cell‐Like Cells Exhibiting Amniotic Differentiation Potentials

Cell Proliferation, EarlyView.
The hfPSC‐LCs could be established from naïve hESCs, conventional hESCs, hiPSCs, and human blastocysts. The hfPSC‐LCs hold robust capacity for three germ layers, hPGCLCs, and hALPCs. ABSTRACT Human embryos undergo pivotal morphogenetic remodelling shortly after implantation. The understanding of this crucial stage is severely impeded by the scarcity of
