Female Infertility

A regenerative path alongside reproductive medicine
Infertility often reflects a micro-environment problem: chronic inflammation, poor micro-circulation, fibrosis, and exhausted cell signalling in the ovary or uterus. In primary ovarian insufficiency/premature ovarian failure (POI/POF), follicles are scarce or underperforming; in intrauterine adhesions (Asherman’s syndrome) and thin endometrium, the basal layer struggles to regenerate; in diminished ovarian reserve, growth signals and vascular support may be inadequate. Assisted reproduction (ovulation induction, IVF/ICSI), surgery, and hormone optimization remain essential but they don’t always re-start the biology of repair. Mesenchymal stem/stromal cells (MSCs), particularly human umbilical cord–derived MSCs (UC-MSCs), are being developed as an adjunct to calm inflammatory noise, improve local blood supply, and deliver pro-regenerative cues so ovarian and endometrial function have a better chance to recover. Recent reviews map this across PCOS, POI/POF, endometriosis, Asherman’s, and treatment-related ovarian dysfunction.
How UC-MSCs may help ovaries and endometrium
UC-MSCs act as cellular coordinators. Through paracrine signalling growth factors, cytokines, chemokines, and extracellular vesicles they temper immune over-activation, reduce apoptosis in vulnerable granulosa and stromal cells, and promote angiogenesis and matrix remodelling. In the ovary, this milieu supports follicular survival/activation and healthier steroidogenic signalling; in the uterus, it encourages re-epithelialization and balanced collagen architecture instead of scarring. Reviews focused on reproductive indications highlight MSC traits most relevant here: immunoregulation, anti-inflammation, pro-angiogenesis, anti-apoptosis, and trophic support, with evidence that secreted vesicles can reproduce many of these effects.
What the research shows
For POI/POF, clinical and translational data point in the same direction. A clinical analysis of women with POI receiving UC-MSC therapy reported restoration signals: increased follicular development, improved oocyte retrieval, and a suggestion that women with shorter amenorrhea and pre-existing antral follicles achieved better outcomes without serious treatment-related adverse events in reported follow-up. In simple terms, when some ovarian potential remains, the MSC-supported environment appears more likely to help it express. Complementary reviews conclude that hUC-MSCs can influence ovarian fibrosis, angiogenesis, immune modulation, and apoptosis, with reports of hormone-level improvements, follicle activation, and functional ovarian restoration in early studies encouraging further controlled trials.
For uterine scarring/thin endometrium (Asherman’s), MSC-centered approaches have shown reductions in fibrotic signalling and improvements in endometrial regeneration across preclinical and early clinical experiences, with MSC-derived extracellular vesicles highlighted as a promising cell-free option. The shared goal is not just to open the cavity surgically, but to re-educate the basal layer so it sustains a receptive lining.
Across female-infertility indications more broadly, a 2024 review synthesizes protocols and preliminary clinical signals for MSCs in PCOS, POI, endometriosis, preeclampsia, and Asherman’s. The consistent pattern: benefits are tied to paracrine biology and depend on source, preparation, and the underlying tissue state hence careful selection and standardized follow-up matter.
Where improvements tend to show up
When the biology shifts in the right direction, teams often see hormone-profile trends (e.g., AMH/FSH moving favourably where reserve exists), richer antral-follicle landscapes on ultrasound, and better oocyte yield/quality metrics during assisted cycles. On the uterine side, the lining appears thicker and more uniform, adhesions are less prone to recur, and implantation parameters improve in programs that pair regeneration with meticulous operative and hormonal care. These objective signals align with what patients notice: more regular cycles after ovarian suppression, clearer follicular responses in stimulation, and fewer setbacks from intrauterine scarring.
Why umbilical-cord sources are a strong fit
UC-MSCs expand efficiently, retain a youthful secretome, and show robust pro-angiogenic and immunoregulatory activity a good match for ischemic, inflamed reproductive tissues. Reviews summarizing UC-MSC use in POI/POF describe multipotency, relatively low immunogenicity, and strong paracrine influence on ovarian and endometrial repair programs.
Other stem-cell platforms and cell-free options
Beyond UC-MSCs, bone-marrow, adipose, placental, and menstrual-blood–derived MSCs appear throughout reproductive-medicine reports, sharing core mechanisms of immunoregulation and angiogenesis with source-specific nuances. Extracellular vesicles/secretome are a fast-moving frontier, aiming to deliver the same trophic messages with streamlined logistics. High-level reviews in female infertility outline these platforms and emphasize that methodology from isolation to re-application matters to outcomes.
PRP as a regenerative adjunct
Although distinct from stem cells, platelet-rich plasma (PRP) is often used beside MSC-oriented care. Recent meta-analyses in diminished ovarian reserve and poor ovarian response show favourable shifts in AMH and FSH, higher antral-follicle counts, and increases in retrieved oocytes and embryos, with signals for pregnancy and live birth in pooled observational data while also noting heterogeneity and the need for rigorous randomized trials. For appropriate candidates, PRP can complement a regenerative plan that targets micro-vasculature and follicular support.
How we integrate this at Vega Stem Cell
Before starting treatment, a complete health assessment is carried out to understand each patient’s condition and goals, allowing the program to be customized for optimal regenerative outcomes. Treatment includes intravenous (IV) stem cell infusion to promote systemic regeneration and intrauterine injection to directly support endometrial repair and improve implantation potential.
Follow-ups focus on monitoring hormonal patterns, follicle counts, endometrial thickness, and overall reproductive outcomes to ensure personalized, data-driven adjustments for each patient.
Putting it all together
Female infertility persists when inflammation, ischemia, and fibrosis outpace repair in the ovary or uterus. UC-MSC centered therapy aims to tilt that biology back: calmer immune tone, richer micro-circulation, protected granulosa and stromal cells, and a more receptive endometrium. Early clinical studies in POI/POF show follicular and functional restoration signals, especially when some reserve remains; broader reviews across Asherman’s and thin endometrium point to meaningful remodelling and receptivity support; and PRP can serve as a complementary tool for selected patients. For the right candidates, these approaches can be woven into comprehensive fertility care with success measured in what matters most: steadier hormone and ultrasound trends, better response in assisted cycles, more receptive linings, and improved chances at pregnancy.
