Characteristics of human spermatozoa harvested in culture media with and without serum proteins [PDF]

open access: yes, 2018
This study was aimed to determine the efficiency of synthetic protein-free media in spermatozoa washing, preparation and retention of the activity of washed spermatozoa over short periods in vitro.

Sperm Sexing in Selected Animals and Humans: Methods, Applications, and Future Prospects

open access: yesAndrology, EarlyView.
ABSTRACT Background Sperm sexing is a technique that enables the selection of offspring sex by sorting spermatozoa based on their sex chromosomes. This technology has gained increasing attention due to its potential applications in both animal breeding and human‐assisted reproduction.

Semen Cryopreservation in Testicular Cancer: Before or After Orchidectomy?

open access: yesAndrology, EarlyView.
ABSTRACT Background Fertility preservation in patients with testicular cancer remains a clinical priority, yet the optimal timing for sperm cryopreservation—before or after orchidectomy—remains a matter of debate. Objectives The aim of this study was to determine the optimal timing for semen cryopreservation and the best‐quality sample for ART.

Maternal exercise improves vascular function in hypertensive offspring via A‐kinase anchoring protein 150 gene (Akap5) epigenetic modifications

open access: yesBritish Journal of Pharmacology, EarlyView.
Background and Purpose Regular physical activity is an effective non‐pharmacological approach to hypertension management and maternal exercise improves offspring cardiovascular health, although mechanisms remain unclear. A‐kinase anchoring protein 150 (AKAP150) targets protein kinase Cα to L‐type Ca2+ channels (CaV1.2), enhancing vascular tone in ...

Homo sapiens, industrialisation and the environmental mismatch hypothesis

open access: yesBiological Reviews, EarlyView.
ABSTRACT For the vast majority of the evolutionary history of Homo sapiens, a range of natural environments defined the parameters within which selection shaped human biology. Although human‐induced alterations to the terrestrial biosphere have been evident for over 10,000 years, the pace and scale of change has accelerated dramatically since the onset

Unraveling the Genetic Mysteries of Müllerian Anomalies: Research Approaches and Clinical Significance

open access: yesClinical Genetics, EarlyView.
This review primarily summarizes the genetic defects in Müllerian anomalies, the tools used to validate these genetic defects, and the future clinical significance of identifying the precise genetic etiology of Müllerian anomalies. ABSTRACT Müllerian anomalies are a collection of heterogeneous anatomical disorders of the female genital tract that ...

Transcription Factor TCF12‐Mediated Maternal Gene Expressions in Mouse Oocyte Are Prerequisites of Successful Fertilisation and Zygotic Genome Activation

open access: yesCell Proliferation, EarlyView.
Maternal TCF12 ensures the competence of fertilisation by controlling the expression of Astl and the proper location of cortical granules. Furthermore, maternal TCF12 maintains the phosphatase activity of PP2A by regulating the expression of Arpp19. Oocyte‐specific deletion of Tcf12 leads to fertilisation defects as well as ZGA failure at the 2‐cell ...

Phosphatase PPP1CC Regulates the First Lineage Segregation by GAS5 in Mouse Preimplantation Embryos

open access: yesCell Proliferation, EarlyView.
Subcortical GAS5 directs PPP1CC phosphatase spatiotemporal positioning during mouse morula‐blastocyst transition, controlling YAP dephosphorylation to drive first embryonic lineage specification. ABSTRACT The transcriptional effector of the Hippo signalling pathway, YAP, regulates the first lineage specification in mouse preimplantation embryos ...

SOX30 Governs Synaptonemal Complex Assembly and Homologous Recombination in Male Meiosis

open access: yesCell Proliferation, EarlyView.
The transcription factor SOX30 directly binds promoter regions of SYCE1 and SYCE2 to mediate their transcriptional activation, thereby enabling proper assembly of central elements within the synaptonemal complex. Structural destabilisation of the synaptonemal complex in Sox30 KK spermatocytes triggers synaptic discontinuity, impairs homologous ...
