Inhibition of IGFBP4 in Granulosa Cells Improves Reproductive Performance and Maintains Fertility With Age via YAP Signaling

Advanced Science, Volume 13, Issue 56, 9 October 2026.
IGFBP4 is upregulated in granulosa cells of aged ovaries across monkeys, mice, and humans. It inhibits YAP signaling, thereby suppressing cell proliferation and contributing to follicular dysfunction. Deletion of Igfbp4 in granulosa cells enhances ovulatory output, improves hormone profiles, and reproductive performance in aged female mice, suggesting ...

Effect of androgen treatment during foetal and/or neonatal life on ovarian function in prepubertal and adult rats [PDF]

, 2012
We investigated the effects of different windows of testosterone propionate (TP) treatment during foetal and neonatal life in female rats to determine whether and when excess androgen exposure would cause disruption of adult reproductive function ...

SDF‐1 Attenuates Oocyte Quality Decline During Reproductive Aging Through Autophagy‐Enhanced Stress Granule Scavenging

Advanced Science, Volume 13, Issue 59, 23 October 2026.
SDF‐1 levels decline significantly with maternal aging. Exogenous supplementation restores meiotic spindle morphology, chromosomal alignment, and mitochondrial function while reducing oxidative stress in aged oocytes. Mechanistically, SDF‐1 enhances autophagic activity to clear accumulated stress granules, thereby rescuing fertilization competence and ...

Systems Pharmacology and Multitarget Modulation of Letrozole–HFD‐Induced Polycystic Ovarian Syndrome by Fruit Pulp of Prunus armeniaca

Chemistry &Biodiversity, Volume 23, Issue 10, October 2026.
Integrated systems pharmacology and in vivo evaluation reveal that hydroalcoholic extract of fruit pulp of Prunus armeniaca (HAE of FPPA) ameliorates letrozole–HFD‐induced PCOS through multitarget modulation. Network analysis identifies 105 shared targets enriched in PI3K/Akt, MAPK, HIF‐1, and inflammatory pathways, while treatment improves hormonal ...

Measurement of Ovarian Reserve Before and After Laparoscopic Polycystic Ovarian Drilling [PDF]

Al-Azhar International Medical Journal
Background: Ovarian reserve refers to the ovary's capacity for reproduction and is measured by the number of follicles present. 6%e8% of reproductive-age women suffer from polycystic ovary syndrome (PCOS), an endocrine condition.
