Myo‐Inositol Mitigates Oxidative Stress in Bovine Mammary Epithelial Cells via Activation of the SIRT5/Nrf2 Signaling Axis

Animal Research and One Health, EarlyView.
Myo‐inositol alleviates oxidative stress in dairy cow mammary epithelial cells via the Sirt5/Nrf2 pathway to promote mitochondrial fusion. This graphical abstract was created with BioRender.com. ABSTRACT High‐yielding dairy cows are susceptible to mammary gland oxidative stress due to prolonged intensive lactation, leading to redox imbalance.

Sperm cryopreservation reduces offspring growth [PDF]

Proceedings of the Royal Society B: Biological Sciences, 2019
Sperm cryopreservation is routinely used in reproductive medicine, livestock production and wildlife management. Its effect on offspring performance is often assumed to be negligible, but this still remains to be confirmed in well-controlled within-subject experiments.

The Oocyte/Antral Follicle Count Index: Does Maximizing Oocyte Yield Translate into Better Assisted Reproductive Technology Outcomes?

Journal of Ultrasound in Medicine, EarlyView.
Objectives Whether aspiration of more oocytes than the antral follicle count (AFC) is beneficial for the current and future products of assisted reproductive technologies (ART) cycles. Methods Data of the first oocyte aspiration for intracytoplasmic sperm injection performed between 2018 and 2022 in attempt to conceive (ICSI, n = 399) or for planned ...

Gestational age determination in pregnancies conceived via assisted reproductive technology

Ultrasound in Obstetrics &Gynecology, EarlyView.
ABSTRACT Objectives To compare gestational age (GA) dating models for pregnancies conceived via assisted reproductive technology (ART), assess whether 14 or 15 days more accurately reflects the median follicular‐phase duration in ART pregnancies and evaluate whether the gestational timelines of ART pregnancies are comparable with that of spontaneously ...
