Superovulation alters telomere length and telomerase component levels in mouse oocytes [PDF]

Journal of Ovarian Research
Assisted reproductive technologies (ARTs) are widely used to treat infertility and include the fundamental step, controlled ovarian stimulation (also known as superovulation).

Advances in the Use of Recombinant Gonadotropins for Reproductive Biotechnologies in Ruminants: A Review. [PDF]

Reprod Domest Anim
ABSTRACT Recombinant gonadotropins, particularly recombinant follicle‐stimulating hormone (rFSH) and recombinant equine chorionic gonadotropin (reCG), have emerged as viable alternatives to traditional animal‐derived hormones in reproductive biotechnologies. This review aims to provide an updated and comprehensive overview of recombinant gonadotropins,

Identification of embryonic yield-related serum biomarkers using proteomic analysis in ovine superovulation [PDF]

Frontiers in Veterinary Science
Superovulation is an efficient technology for the propagation of excellent livestock. Blood proteins other than reproductive hormones might be related to the outcome of superovulation.

Mechanism and Intervention of the NPY1R/CREB Signaling Axis in Regulating Inflammatory Response in Aged Ovarian Granulosa Cells and Ovarian Senescence. [PDF]

FASEB J
Aging‐associated upregulation of NPY1R drives p‐CREB activation, triggering inflammation, mitochondrial dysfunction, and extracellular matrix imbalance to promote ovarian senescence. Pharmacological inhibition of NPY1R with BIBO 3304 restores ovarian homeostasis, highlighting a therapeutic strategy for reproductive aging. ABSTRACT Ovarian senescence is

Expression profile analysis of sheep ovary after superovulation and estrus synchronisation treatment

Veterinary Medicine and Science, 2022
Superovulation is a widely used reproductive technique in livestock production, but the mechanism of sheep's superovulation is not yet clear. Here, a method of superovulation and estrus synchronisation was used to treat female Duolang sheep.

Effects of multisuperovulation on the transcription and genomic methylation of oocytes and offspring [PDF]

Clinical Epigenetics
Background Controlled ovarian stimulation is a common skill of assisted reproductive technologies (ARTs). In the clinic, some females would undergo more than one controlled ovarian stimulation cycle.

Serum concentrations of anti-Müllerian hormone modulate ovarian response to different doses of follicle-stimulating hormone in Japanese Black donors [PDF]

The Journal of Reproduction and Development
Anti-Müllerian hormone (AMH) is a marker for predicting embryo production in cows subjected to superovulation; however, it remains to be established as a reliable predictor of reproductive performance.

Granulosa cell transcription is similarly impacted by superovulation and aging and predicts early embryonic trajectories [PDF]

Nature Communications
In vitro fertilization efficiency is limited in part because a fraction of retrieved oocytes fails to fertilize. Accurately evaluating their quality could significantly improve in vitro fertilization efficiency, which would require better understanding ...

Anti-Müllerian Hormone as a Marker for Castration Status and Fertility in Bulls and Oxen. [PDF]

Reprod Domest Anim
ABSTRACT Anti‐Müllerian hormone (AMH) has been established as an indicator of castration status and fertility in several species. However, its applicability in postpubertal bulls and oxen has not yet been thoroughly investigated. This study examined 73 bulls aged between 12 and 107 months and 37 oxen older than 12 months.

Effects of Short-Term Differences in Concentrate Feeding on the Recovery of In Vivo Embryos in Hanwoo Donor Cows through Superovulation Treatment [PDF]

Animals
Superovulation is a technique used to increase the number of oocytes released for fertilization. This study investigated the effects of short-term differences in concentrate feed intake on in vivo embryo production through superovulation in indigenous ...
