“…Controlled ovarian hyperstimulation (COH) is widely used in IVF-ET to obtain a sufficient number of oocytes for downstream processing [130]. However, successful ovulation is accompanied by a rapid increase in OS levels and inflammatory response [131]; thus, whether COH can lead to ovarian OS damage has received widespread attention.…”

The role of oxidative stress in ovarian aging: a review

Ovarian aging refers to the process by which ovarian function declines until eventual failure. The pathogenesis of ovarian aging is complex and diverse; oxidative stress (OS) is considered to be a key factor. This review focuses on the fact that OS status accelerates the ovarian aging process by promoting apoptosis, inflammation, mitochondrial damage, telomere shortening and biomacromolecular damage. Current evidence suggests that aging, smoking, high-sugar diets, pressure, superovulation, chemotherapeutic agents and industrial pollutants can be factors that accelerate ovarian aging by exacerbating OS status. In addition, we review the role of nuclear factor E2-related factor 2 (Nrf2), Sirtuin (Sirt), mitogen-activated protein kinase (MAPK), protein kinase B (AKT), Forkhead box O (FoxO) and Klotho signaling pathways during the process of ovarian aging. We also explore the role of antioxidant therapies such as melatonin, vitamins, stem cell therapies, antioxidant monomers and Traditional Chinese Medicine (TCM), and investigate the roles of these supplements with respect to the reduction of OS and the improvement of ovarian function. This review provides a rationale for antioxidant therapy to improve ovarian aging.

“…Compared with a single uterine spiral artery, the uterine artery reflects the blood flow perfusion of the entire uterus, and the uterine artery S/D is not a commonly used measurement index to assess endometrial receptivity during IVF-ET and typically requires the assessment of uterine artery PI, RI, and other indicators for a comprehensive judgment, and measuring uterine artery PI and RI on IVF-ET days is more useful in determining whether the endometrium is in a state suitable for embryo adhesion and completion of implantation ( 31 ). The pooled results showed that the S/D of the pregnancy group after receiving IVF-ET were significantly lower than that of the non-pregnancy, while the difference between RI and PI in the pregnancy group and the non-pregnancy group after receiving IVF-ET was not statistically significant.…”

At present, there are currently no reliable and consistent conclusions regarding transvaginal ultrasound assessment of endometrial receptivity in predicting clinical pregnancy outcomes of in vitro fertilization-embryo transfer (IVF-ET). Thus, in the present study, a meta-analysis was performed on multiple endometrial receptivity indices detected by vaginal ultrasound, aiming to provide a diagnostic basis for clinical practice. PubMed, Embase, and Cochrane Library databases were searched for studies published between the establishment of the databases through to January 2023. Studies that reported infertile women undergoing IVF-ET and undergoing vaginal ultrasound were included, but repeat publication, studies where the full text was not obtainable, studies where there was incomplete information provided or data extraction was not possible, studies on animals, case reports, reviews, and systematic reviews were excluded. STATA 15.1 was used to analyze the data. The pooled results showed that the endometrial thickness [Weighted mean difference (WMD)=0.03, 95% CI: 0.00-0.06; P=0.022] and endometrial volume (WMD=0.41, 95% CI: 0.07-0.74; P=0.017) of the pregnancy group after receiving IVF-ET were all significantly higher than that of the non-pregnancy group. The pooled results also showed that the vascularization index (VI) (WMD= 0.79, 95% CI: 0.56-1.03; P= 0.000), flow index (FI) (WMD=1.82, 95% CI: 0.83-2.81; P=0.000) and vascularization flow index (VFI) (WMD=1.58, 95% CI: 0.91-2.24; P=0.000) of the pregnancy group after receiving IVF-ET was significantly higher than that of the non-pregnancy group. Systolic/diastolic (S/D) (WMD=-4.92, 95%CI: -8.28--1.56; P=0.004) of the uterine artery of the pregnancy group after receiving IVF-ET was significantly lower than that of the non-pregnancy group. However, the differences between the resistance index (RI) and pulsatility index (PI) in the pregnancy group vs. the non-pregnancy group after receiving IVF-ET were not statistically significant. Vaginal ultrasound can be used to predict the outcomes of pregnancy in infertile women undergoing IVF-ET by measuring the thickness and volume of the endometrium, combined with the S/D, VI, FI, and VFI of the uterine artery.
