Context: The developmental potential (DP) of in vitro matured (IVM) oocytes is considerably lower than that of in vivo matured oocytes, primarily due to the premature resumption of meiosis without adequate cytoplasmic mat...
The biology of the ovary -Honouring the contributions of Ken P McNatty and Rex J Scaramuzzi [0.03%]

Once viewed simply as a pipeline connecting the ovary and uterus where fertilization and early development occur, the oviduct is becoming more appreciated for its complex functions. The utero-tubal junction (UTJ) restricts the entry of sper...
Expression of Sortilin 1-like immunoreactive proteins, an endocytic receptor for pathogenic α-synuclein fibrils, in bovine GnRH neurons: observations in young and aged animals [0.03%]
牛促性腺激素释放激素神经元中类似分拣蛋白1免疫反应性蛋白(病理性α-突触核蛋白纤维的内吞受体)表达:年轻及老龄动物观察结果

Context: Ageing is associated with reduced fertility, yet the neuronal basis of reproductive decline remains poorly understood. Alpha-synuclein (αSYN), a protein implicated in neurodegeneration, accumulates in bovine gon...

Pregnancy losses due to early embryonic mortality remain a major concern in farm ungulates, including cattle, sheep, pigs and goats. The majority of these losses occur during conceptus elongation, a developmental phase unique to ungulates t...

Advancements in multi-omics profiling and targeted molecular functional tools have led to significant progress in our understanding of early embryonic development in mammals. This is very relevant in the beef and dairy industries for explor...
Heterospermic semen: Implications for managing bull-to-bull variation in fertility [0.03%]

Heterospermic (HS) bull semen involves mixing the semen from two or more sires in the same semen straw. It has the potential to protect against sub-fertile bulls which pass semen quality control checks, due to the presence of sperm from oth...

Historically, bacteria identified within the reproductive tract of cattle using culture-based techniques were associated with disease. Indeed, bacterial genera including Fusobacterium, Bacteroides, Prevotella, and Porphyromonas identified b...

Juvenile in vitro embryo transfer (JIVET) employs oocytes from prepubertal females to reduce generation intervals. In human, it offers potential applications for fertility preservation in young cancer patients. Ruminant animals are good mod...
