Ovarian cryopreservation and transplantation is a fertility preservation option, but a majority of follicles were lost due to grafting process. Accelerated activation of primordial follicle and follicle apoptosis are responsible for follicle depletion following grafting. Since apoptosis and...

The cargo carried by extracellular vesicles (EVs) plays an important physiological role in their corresponding target organs or target tissue cells. Extracellular vesicles are classified into large extracellular vesicles (LEVs) and small extracellular vesicles (SEVs) according to their diameters....

In mammalian reproduction, granulosa cell proliferation and apoptosis are critical in oogenesis, folliculogenesis, and follicular atresia. Regulating various physiological activities of cells at the post-transcriptional level, microRNA (miRNA) is an endogenous non-coding small RNA. Due to the...

Circular RNAs (circRNAs) play vital roles in regulating biological processes. However, the contributions of circRNAs to BMPR2 regulation during follicle development remain unknown. In this study, we first verified the optimal conditions for BMP15 and GDF9 treatment in bovine cumulus cells. Then, we ...

Despite established microscopic markers of feline oocyte quality, little is known about their ultrastructural traits. To the best of our knowledge, there is no published report analysing the effect of 24 and 48 h ovarian storage time on the domestic cat oocytes characteristics at the...

The objectives of this study were: (a) To report anti-Müllerian hormone (AMH) serum concentrations in neonatal, pre and postpubertal female cats. (b) To establish the relationship between serum AMH with either age and estrous cycle (c) To correlate the total number of different ovarian follicle...

The alteration of signaling molecules involved in the general metabolism of animals can negatively influence reproduction. In dairy cattle, the development of follicular cysts and the subsequent appearance of ovarian cystic disease (COD) often lead to decreased reproductive efficiency in the herd....

In the clinical procedure, corpus luteum identification in the ovary is important to determine the reproductive status of cows. There are two methods to determine corpus luteum in live cows, rectal palpation and ultrasound examination. However, real imaging cannot be obtained by these methods....

Carbon dioxide (CO₂) is commonly used to immobilize insects and to induce reproduction in bees. However, despite its wide use and potential off-target impacts, its underlying mechanisms are not fully understood. Here, we used Bombus impatiens to examine whether CO₂ impacts are mediated by anoxia...

Sexually mature Heteropneustes fossilis were exposed to cadmium at acute, lethal and sublethal concentrations at both short and long term intervals. Following exposure, cadmium disrupted reproductive function in both the sexes. Results show determental effects of cadmium in the testes as evinced by ...
