Intra Ovarian Muse Cell Injection for Perimenopause Symptom Relief and Ovarian Function Restoration (MUSE-OVARY)

This observational study examines the safety and effects of injecting Muse cells (a type of naturally occurring stem like cells found in adult tissues such as fat or bone marrow) directly into the ovaries of women aged 28 to 70 who are going through peri-menopause. Perimenopause is the transition time before menopause when hormone levels fluctuate, periods become irregular, and many women experience symptoms like hot flashes, night sweats, sleep problems, mood changes, and reduced energy. Current treatments mainly manage symptoms but do not restore natural ovarian function. Muse cells have special properties: they can help repair tissues, reduce inflammation, support cell energy production, and promote a healthier environment in the ovaries. In this study, women who choose to receive ultrasound guided Muse cell injections into their ovaries as part of their own regenerative care will be carefully followed. Researchers will monitor safety, hormone levels (such as FSH, estrogen, and AMH), ovarian follicle counts via ultrasound, menstrual patterns, and quality of life improvements using questionnaires. The study does not assign treatment - participants and their doctors decide on the procedure, and information is collected in a standardized way over 24 months (with longer safety follow-up). The goal is to gather real world data on whether this approach can help stabilize hormones and support ovarian tissue during perimenopause. No placebos or experimental drugs are used in this observational study.

Ovarian Function Following Intraovarian Injection of PRP

Consenting women with evidence of poor ovarian reserve will be randomly assigned to treatment with either Platelet Rich Plasma (PRP) or Platelet Poor Plasma (PPP).

DPOS Versus GnRH Antagonist Protocol for Oocyte Accumulation in Low Ovarian Reserve Patients: An RCT

One of the barriers in patients with diminished ovarian reserve (DOR) is the significantly reduced number of oocytes resulting in fewer oocytes collected and embryos formed. Many ovarian stimulation strategies have been proposed to improve oocyte or embryo quantity which is oocyte accumulation could be a potential option with a comparable success rate and reasonable cost. Progestin-primed ovarian stimulation (PPOS) protocol could be suggested as an alternative method of premature Luteinizing hormone (LH) prevention in IVF. It favors segment Assisted Reproductive Technology (ART) cycles such as frozen embryo transfer (FET), oocyte donor, fertility preservation, and oocyte accumulation set. The protocol is more patient-friendly and affordable than the GnRH antagonist regimen regarding LH suppression during ovarian stimulation. Many PPOS protocols have been proposed in which the three most common agents include Dydrogesterone (DYG), Micronised Progesterone (MIP), and Medroxyprogesterone acetate (MPA). Indeed, DYG seems to have some advantages, including oral administration and safety which has been used in the treatment of threatened abortion. Initial evidence of PPOS protocol suggests that oocyte quantity and quality are comparable with other ovarian stimulation regimens. However, data related to the PPOS protocol has not been well documented, including Dydrogesteron-primed ovarian stimulation (DPOS). There has not been an RCT with a large sample size and well-designed to provide more substantial evidence. A randomized trial to compare the effectiveness of PPOS and GnRH antagonist protocol in IVF is urgently needed.

Characterization of Gut and Tongue Coating Microbiota in Patients With Diminished Ovarian Reserve

The goal of this observational study is to investigate the distinct tongue manifestation characteristics in patients with diminished ovarian reserve (DOR) compared to healthy individuals, and to clarify the features of tongue coating microbiota, gut microbiota, and their interrelationships in DOR patients. The main question it aims to answer is: Whether there are significant differences in tongue manifestations, tongue coating microbiota, and gut microbiota characteristics between DOR patients and healthy populations; Whether associations exist between tongue coating microbiota and gut microbiota in DOR patients; Whether the pathogenesis of DOR may influence estrogen metabolism through alterations in oral and gut microbiota.

The Effect of VitC on IVF Outcome of DOR Patients

In the context of the accelerating aging population and the continuous decline in birth rates nationwide, delaying reproductive aging in women and protecting the fertility of women of childbearing age have become urgent issues and key demands that need to be addressed in the field of maternal and child health in China. The ovaries have reproductive and hormone secretion functions and are crucial throughout the female reproductive lifecycle. Women of childbearing age in China face a serious problem of diminished ovarian reserve (DOR), which can lead to infertility, failed in vitro fertilization (IVF) treatments, miscarriage, and other adverse pregnancy outcomes, severely affecting the safety of women and their offspring. For DOR patients who desire to conceive, failure to intervene and treat promptly can result in irreversible losses and impose a significant psychological burden on them. However, there are currently no clear and reliable interventions that can improve ovarian function and enhance fertility in women with DOR. Therefore, exploring new, safe, and patient-acceptable intervention strategies is urgently needed, as it may bring hope and light to women with DOR. Nutrient supplementation, especially vitamin supplementation, has received increasing attention in disease treatment due to its safety, bioavailability, and effectiveness. Previous studies have shown that vitamin C may play an important role in treating diminished ovarian reserve. However, its effects on ovarian function need to be validated in the population. Based on the above research background, this project will conduct a randomized, placebo-controlled, double-blind, multicenter trial. The study subjects will be DOR infertility patients undergoing IVF/ICSI treatment. The intervention group will receive oral vitamin C supplementation at a dosage of 500 mg per dose, twice a day; the control group will receive a placebo with the same dosage and method for at least three months. Patients will be followed up until delivery outcomes, comparing the IVF/ICSI treatment results between the vitamin C supplementation group and the placebo group. The primary endpoint of this clinical trial is the live birth rate of the IVF/ICSI treatment cycle. Secondary endpoints include indicators of improved ovarian reserve function, ovarian aging molecular clocks, IVF-embryo culture indicators, pregnancy rates, pregnancy complications, and neonatal conditions, thereby providing new clues and theoretical basis for clinical treatment plans for DOR patients.

Ovarian PRP for Diminished Ovarian Reserve

This prospective double-blinded randomized placebo control study aims to determine if In Vitro Fertilization (IVF) outcomes are improved by ovarian platelet-rich plasma injections (oPRP) for women diagnosed with diminished ovarian reserve (DOR). Women with DOR notoriously have the lowest chance of pregnancy and live birth compared to age-matched peers with a normal or robust ovarian reserve.

Clinical Trial of Anovulatory Infertility

This project aims to study the expression of clock genes and related proteins in follicular fluid and granulosa cells, depicting the periodic, amplitude, and phase changes of biological clock genes and related proteins in women of different ages during the reproductive period and in patients with ovulatory disorders. The study compares the periodicity, amplitude, and phase changes of Clock/Bmal1-TTFLs-klotho related proteins and genes in PCOS, DOR patients, and age-matched women with normal ovarian function, aiming to identify the key segments of ovarian clock gene period rhythm disorder under different disease states, and screen the key time points of clock gene oscillation abnormality. Omics analysis of the differences between groups, analysis of the relationship between gene transcription translation, protein expression, metabolites, and the expression of clock genes, and deduction of the dynamic changes and interaction relationships of the biological processes within the ovaries in regulating ovulatory disorders using the method of reinforcing the kidney and regulating the menstrual cycle. This aims to clarify that maintaining the ovarian biological clock period rhythm is an important biological basis for "the kidney dominating reproduction". The regulation mechanism of the treatment of ovulatory disorders using the method of reinforcing the kidney and regulating the menstrual cycle is explained from the perspective of the ovarian biological clock period rhythm.

The Correlation Between Ovarian Function and Serum Biomarkers

The goal of this observational study is to find differences in serum biomarkers between ovarian function and normal individuals.

The Effeciency of NMN in Improving IVF/ICSI-ET Pregnancy Outcomes in Patients With DOR

The purpose of the study is to understand the effect of nicotinamide mononucleotide (NMN) on patients with diminished ovarian reserve and the outcomes of IVF/ICSI-ET.

Study of Acupoints in Diminished Ovarian Reserve Based on Biological Characteristics

Diminished Ovarian Reserve (DOR) is characterized by decreased female fertility, menstrual disorders and perimenopausal symptoms due to sex hormone deficiency or fluctuations. For now, there are no uniform diagnostic criteria or an ideal single detection index for DOR because of its insidious etiology and pathogenesis,theories suggest that there are specific changes in the body surface or acupuncture points in a pathological state. By detecting the biological characteristics of relevant meridian points and exploring the specificity and regularity of it.
