Objective: Does an association exist between diminished ovarian reserve (DOR) and embryonic aneuploidy risk in young women of reproductive age?
Methods: This retrospective cohort study included 854 participants treated in the Department of Reproductive Medicine, Women's Hospital of Nanjing Medicine University, Nanjing Maternity and Child Health Care Hospital, from May 2016 to September 2023 for a total of 894 cycles. The relationship between ovarian reserve and embryonic euploidy was evaluated using statistical methods such as generalized estimating equation (GEE) and propensity score matching (PSM).
Results: Despite the higher number of biopsied blastocysts in women with normal ovarian reserve, no significant difference in embryonic aneuploidy rates was observed between DOR women and the control group. In addition, there were no significant disparities observed in the rates of metaphase II (MII) oocytes, normal fertilization, transferable embryos, blastocyst formation, and high-scoring blastocysts between the DOR and control groups after PSM.
Conclusion: This study showed that DOR had no significant effect on the incidence of aneuploidy in embryos. Young women informed about DOR should be relatively confident about the quality of their eggs and the euploidy status of their embryos before conventional assisted reproduction, thereby mitigating concern regarding adverse maternal outcomes due to aneuploidy.

Background: The aim of this study was to investigate the role of miR-361-5p (a tumor suppressor) in regulating granulosa cell function by targeting SLC25A24, a key mitochondrial protein, to uncover potential therapeutic targets for diminished ovarian reserve (DOR).
Methods: This study included patients undergoing assisted reproductive technology treatment at our hospital. Granulosa cells were isolated from follicular fluid, and KGN cells were used for in vitro experiments.
Objective: We aimed to compare highly purified human menopausal gonadotropin (hp-hMG) and recombinant follicle stimulating hormone (rFSH) in short antagonist in vitro fertilization (IVF) cycles of patients with poor ovarian reserve (POR). Limited research exists on this comparison in short antagonist cycles for this patient group.
Materials And Methods: This retrospective cohort study involved 165 POR patients aged 18-45 years who underwent IVF between 2018 and 2022.

Objective: To establish a murine model of chemotherapy-induced diminished ovarian reserve (DOR) and investigate residual fertility after chemotherapy exposure.
Design: Two different chemotherapy protocols were tested to establish a valid DOR model by comparing follicle densities in mice given either protocol versus physiological solution. An ovarian stimulation protocol was then selected from among different gonadotropins by counting the number of day-2 embryos obtained from normal mice.

Menopause occurs due to the depletion of the ovarian reserve, leading to a progressive decline in estrogen (E2) levels. This decrease in E2 levels increases the risk of developing several diseases and can coexist with chronic kidney disease (CKD). Arterial hypertension (AH) is another condition associated with menopause and may either contribute to or result from CKD.

Gengnianchun (GNC) is a traditional remedy used for diminished ovarian reserve, but its underlying mechanisms remain unclear. This study aimed to explore these mechanisms in human granulosa-like cancer (KGN) cells pretreated with medicated rat serum (MRS) before HO exposure. MRS pretreatment significantly alleviated HO-induced cell damage, including improvements in cell viability, superoxide dismutase and GSH-Px activities, and Bcl-2 expression.
