Advanced Science, EarlyView.SDF‐1 levels decline significantly with maternal aging. Exogenous supplementation restores meiotic spindle morphology, chromosomal alignment, and mitochondrial function while reducing oxidative stress in aged oocytes. Mechanistically, SDF‐1 enhances autophagic activity to clear accumulated stress granules, thereby rescuing fertilization competence and ...

Sperm Competition and the Function of Masturbation in Japanese Macaques (Macaca fuscata) [PDF]
, 2001 Male masturbation or sexual-auto stimulation is well documented in humans. This study dealt with the occurrence of masturbation in non-human primates in general, and in Japanese macaques (Macaca fuscata) in particular, from the perspective of ...

Computational Modelling of Sperm Behaviour in a 3D Virtual Oviduct [PDF]
, 2011 The processes by which individual sperm cells navigate the length and complexity of the female reproductive tract and then reach and fertilise the oocyte are fascinating. Numerous complex processes potentially influence the movement of spermatozoa within

Advanced Science, EarlyView.Embryonic amoxicillin exposure disrupts multi‐organ development in zebrafish larvae through a lncRNA–metabolic enzyme regulatory axis. PCALRx associates with pyruvate carboxylase, promotes PC protein ubiquitination, and impairs mitochondrial energy metabolism, while vitamin B1 partially restores PC‐centered metabolic function and developmental outcomes.

Reduced glutathione and cysteine hydrochloride on crossbred bull semen [PDF]
, 2012 Over the last few years, good quality freezable semen was not utilized effectively due to less knowledge about the freezability of semen. One reason is the lack of sufficient antioxidants in the seminal plasma and semen extender.

Effects of cryopreservation on mitochondrial function and sperm quality in fish
Aquaculture, 2019 The development of cryopreservation techniques has led to important changes in animal reproductive biotechnology. However, these techniques are associated with cellular and molecular damage, affecting the mitochondrial function and quality of spermatozoa;

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 ...

Aberrant expression of sperm-specific glycolytic enzymes are associated with poor sperm quality
Molecular Medicine Reports, 2019 The energy required for normal sperm function is mainly generated by glycolysis and oxidative phosphorylation. Testis-specific glycolytic enzymes are expressed in germ cells and present in mature spermatozoa.
