Lowering Sperm Dose Rates in Frozen Semen for Bovine Artificial Breeding [PDF]

, 2007
The New Zealand Dairy industry relies on artificial breeding to produce high genetic merit replacement stock. Proven bull semen is extended and preserved as either ambient temperature product or as frozen doses.

Functional Sex Reversal in Adult Gonochoristic Teleosts is Mediated by Ovarian Germline Stem Cell Plasticity and Somatic Cell Transdifferentiation

Advanced Science, EarlyView.
Oocytes play crucial roles in maintaining ovarian fate in adult gonochoristic fish. Targeted oocyte ablation with aromatase inhibition triggers the activation of surviving germline stem cells and the transdifferentiation of somatic cells from granoulosa/theca to Sertoli/Leydig lineages, inducing a complete and functional female‐to‐male sex reversal ...

Elevated Lipid Concentrations in Seminal Plasma Can Reduce Sperm Motility in Simmental Bulls

Animals
Sperm motility is a key factor influencing male fertility and is associated with metabolic and lipid profiles across species. The aim of this study was to investigate the relationship between sperm motility and the seminal plasma lipid profile in ...

Effect of electroacupuncture on total motile sperm count and sperm motility

Journal of Public Health Research
Background: Approximately 50% of infertility cases are attributed to male factors. Acupuncture has long been employed as a complementary therapy to enhance male infertility treatment outcomes. This study aimed to assess the impact of electroacupuncture (EA) therapy on sperm motility and TMSC in male infertility ...

RNA Promotes Synapsin Condensates That Organize Synaptic Vesicles in Live Neurons and Enable Localized Translation in Reconstituted System

Advanced Science, EarlyView.
Condensates at synapses organize synaptic vesicles (SVs) and are crucial for efficient neurotransmitter release, yet how RNA contributes to this mesoscale architecture remains poorly understood. Here we uncover that RNA modulates synapsin–driven condensates.

The association between male infertility and sperm disomy: Evidence for variation in disomy levels among individuals and a correlation between particular semen parameters and disomy of specific chromosome pairs [PDF]

, 2004
BACKGROUND: The association between infertility and sperm disomy is well documented. Results vary but most report that men with severely compromised semen parameters have a significantly elevated proportion of disomic sperm.

BOULE is Essential for the Dynamic Disassembly of Heat Shock Granules in Male Germ Cells

Advanced Science, EarlyView.
BOULE orchestrates stress granule disassembly in germ cells via a two‐pronged mechanism: it promotes G3BP1 ubiquitination by upregulating TRIM27, generating a signal for VCP/FAF2 recruitment, and it maintains G3BP1 and FAF2 protein levels. BOULE deficiency disrupts disassembly complex formation, leading to impaired heat shock granule clearance ...

Relationship between sperm progressive motility and DNA integrity in fertile and infertile men

Middle East Fertility Society Journal, 2018
Background: Progressive sperm motility was found to be predictive for in vitro and in vivo fertilization. There has been an increase in the literature of studies investigating whether DNA fragmentation could be associated with other semen parameters ...

A Magnetic‐Driven Self‐Rotation‐Stabilized Miniature Swimming Robot

Advanced Science, EarlyView.
Inspired by the stable rotational descent of seeds in nature, this study designs a magnetic‐driven self‐rotation‐stabilized miniature swimming robot (MSMSR). Based on a resonance‐driven strategy, the robot exhibits high swimming performance, offering enhanced directional swimming and improved resistance to water flow disturbances compared to existing ...
