Objective: This study explores the metabolic profiles in the peripheral blood of infertile patients with adenomyosis (ADM) to identify key metabolites affecting pregnancy outcomes in these patients undergoing frozen embryo transfer (FET). Our goal is to create a metabolite-based clinical prediction model for pregnancy outcomes in adenomyosis-associated infertility.
Methods: This prospective cohort study from the Reproductive Center at Peking University Third Hospital enrolled 94 infertile patients with adenomyosis and control (CTRL) patients undergoing FET.

The Balkan Peninsula is a European biodiversity hotspot, home to 6,500 native vascular plant species, many of which are endemic. The region has diverse range of climates and complex topography, creating conditions that suit many woody ornamental, fruit, and forest species. Nevertheless, climate change, habitat destruction, invasive species, plant diseases, and agricultural practices threaten natural ecosystems and cultivated species.

In an era of expanding reproductive possibilities, the human embryo has come to represent both immense potential and profound constraint. Advances in medically assisted reproduction (MAR) have led to the cryopreservation of hundreds of thousands of embryos each year, yet many remain unused and are ultimately discarded. Meanwhile, studies aimed at understanding infertility, early human development and preventing miscarriage continue to face significant barriers, with only a small fraction of embryos ever donated to research.

Immature zebrafish oocytes are highly susceptible to high temperatures, making it difficult to warm cryopreserved oocytes rapidly. In the present study, we aimed to investigate whether thermosensitive channels, lipid mediators, and ferroptosis are involved in heat stress-induced injury in immature zebrafish oocytes. Oocytes were injected with inhibitors of a heat-sensitive channel (TRPV1) and multiple enzymes-cytosolic phospholipase Aα (cPLAα), cyclooxygenases (COXs), arachidonate lipoxygenase 5 (ALOX5), and lysophosphatidylcholine acyltransferase 2 (LPCAT2).

Summary Answer: A predictive model incorporating patient age, antral follicle count (AFC), anti-Müllerian hormone (AMH), and FSH levels achieved the greatest predictive accuracy.
What Is Known Already: As a consequence of societal evolution, women are increasingly delaying starting a family. However, the natural decline in ovarian reserve and oocyte quality as age advances can increase the risk of age-related fertility decline (ARFD) and involuntary childlessness.
