The quality and maturation of an oocyte not only play decisive roles in fertilization and
embryo success, but also have long-term impacts on the later growth and development of …

Contents Fertility in high yielding dairy cows is declining, and there is increasing evidence to
presume that oocyte and embryo quality are major factors in the complex pathogenesis of …

Simple Summary The efficiency of producing embryos using in vitro technologies in cattle
species remains lower when compared to mice, indicating that the proportion of female …

BACKGROUND While oocyte IVM is practiced sporadically it has not achieved widespread
clinical practice globally. However, recently there have been some seminal advances in our …

Contents For several decades, researchers worldwide report a decrease in fertility in high‐
yielding dairy cows, most probably based on conflicting metabolic and reproductive needs …

After parturition, dairy cows undergo a plethora of metabolic, inflammatory, and immunologic
changes to adapt to the onset of lactation. These changes are mainly due to the homeorhetic …

Reduced oocyte and embryo quality are recognised as major factors in the problem of
disappointing fertility in high producing dairy cows. This review aims to shed more light on …

Various morphological and cytological traits of oocytes and their surrounding cumulus cells
may be used to select oocytes for assisted reproduction. However, even with careful …

To identify the genes related to oocyte competence, we quantified transcripts for candidate
genes in oocytes (H1Foo, H2A, H3A, GHR, GDF9, BMP15, OOSP1) and cumulus cells …

The present study compared the distribution and steroid composition of 3-, 4-and 5–8-mm
follicles on the surface of prepubertal and adult ovaries, and determined the relationship …
