Impact of Sorting and Catch Media on Porcine Sperm Motility, Capacitation, and Viability
Andrology, EarlyView.ABSTRACT Background Fluorescence‐activated cell sorting (FACS) has emerged as a powerful tool for selecting spermatozoa of a desired population of fluorescent biomarkers, offering potential applications in reproductive biology and agriculture. However, concerns remain regarding sorting‐induced physiological alterations that could compromise spermatozoa

Effect of equilibration time on clinical and neonatal outcomes in human blastocysts vitrification
Reproductive Medicine and Biology, 2020 Purpose Prolonged exposure to equilibration solutions may be detrimental to an embryo's developmental potential, whereas a shorter exposure may affect the penetration of cryoprotectants into blastomeres.

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.

Andrology, EarlyView.ABSTRACT Background Oligoasthenoteratozoospermia (OAT), characterized by reduced sperm count, impaired motility, and abnormal morphology, is a major cause of male infertility with substantial genetic heterogeneity. However, the underlying genetic etiology remains unresolved in a large proportion of affected individuals.

Improving ARTs: Microfluidics as a Tool for Sperm Selection
Andrology, EarlyView.ABSTRACT Sperm selection is a critical step in assisted reproductive technology (ART), as sperm quality directly influences embryo quality. In vivo, the female reproductive tract imposes several physical and physiological barriers that favors only the most optimal spermatozoa reaching the fertilization site.

Regulation of blastocyst formation
Frontiers in Bioscience, 2001 Preimplantation or pre-attachment development encompasses the "free"-living period of mammalian embryogenesis, which directs development of the zygote through to the blastocyst stage. Blastocyst formation is essential for implantation, establishment of pregnancy and is a principal determinant of embryo quality prior to embryo transfer.

A Defense of Post‐Viability Abortion
Bioethics, EarlyView.ABSTRACT It is often thought that Thomson's Violinist argument is only applicable before the point of viability. In this paper, I propose that this is not the case, offering a novel defense of post‐viability abortion utilising Thomson's self‐defense framework. I first set out Thomson's Violinist argument and how it interacts with viability.

New biosensors and transgenic mice for multiplex cGMP imaging
British Journal of Pharmacology, EarlyView.Background and Purpose Cyclic guanosine monophosphate (cGMP) is a versatile second messenger that is important for human (patho‐)physiology and pharmacotherapy. Live‐cell imaging of cGMP with biosensors allows to elucidate its spatiotemporal dynamics in real time under close‐to‐native conditions. However, to monitor two separate cGMP pools or cGMP/cAMP
