INVO Fertility Announces Five Poster Presentations Highlighting Platelet-Rich Plasma Research at the 2026 Midwest Reproductive Symposium International
Rhea-AI Summary
INVO Fertility (Nasdaq: IVF) announced that Dr. Gretchen Collins from its Wisconsin Fertility Institute presented five retrospective platelet-rich plasma (PRP) studies at the 2026 Midwest Reproductive Symposium International in Chicago. The research evaluated ovarian and subendometrial PRP in IVF patients with prior poor response, diminished ovarian reserve, thin endometrium, or other treatment-limiting factors.
Across small cohorts (17–19 patients for ovarian PRP; 9 patients for subendometrial PRP), findings included age- and ovarian-reserve–dependent ovarian response, increased oocyte yield and blastocyst quality, de novo euploid embryos and spontaneous conceptions in some poor responders, higher embryo transfer rates, improved endometrial thickness (mean 6.1 mm to 8.1 mm), restoration of trilaminar pattern, and resolution of intrauterine fluid. All abstracts are retrospective and, according to INVO Fertility, warrant confirmation in larger, prospective studies.

Research from Wisconsin Fertility Institute evaluates ovarian and subendometrial PRP in patients with prior poor IVF response and endometrial-development challenges
SARASOTA, Fla., Aug. 20, 2026 (GLOBE NEWSWIRE) -- INVO Fertility, Inc. (Nasdaq: IVF) ("INVO Fertility" or the "Company"), a healthcare fertility company focused on the establishment, acquisition, and operation of fertility clinics and related businesses and technologies, today announced that Gretchen Collins, M.D., of the Company's Wisconsin-based clinic, Wisconsin Fertility Institute, presented five poster abstracts at the 2026 Midwest Reproductive Symposium international ("MRSi"), held on July 26-29, 2026, at The Drake Hotel in Chicago, Illinois. This year's meeting theme was "In Full Bloom – The Future of IVF."
Dr. Collins is a double board-certified obstetrician-gynecologist and reproductive endocrinology and infertility specialist. The five retrospective studies evaluated ovarian and subendometrial platelet-rich plasma ("PRP") in patients with prior poor IVF outcomes, diminished ovarian response, thin endometrial lining, or other factors that had limited treatment progression.
"On behalf of the entire INVO Fertility team, we congratulate Dr. Collins and appreciate the work of the clinical team in developing and sharing these findings. It is extremely rewarding to see five poster abstracts from Wisconsin Fertility Institute presented at this year's MRSi, which follows our decision to introduce PRP therapy as an additional patient option in Wisconsin last year," said Steve Shum, Chief Executive Officer of INVO Fertility. "The selection of this work for presentation reflects the clinical expertise and commitment to patient-centered innovation within our expanding clinic platform."
"As we continue to build INVO Fertility and our clinic operations, we believe supporting physician-led research and knowledge-sharing can contribute to better patient care, strengthen our clinics, and advance our mission of expanding access to assisted reproductive technology," stated April McGhee, Chief Operating Officer of INVO Fertility.
All five posters were presented by Dr. Collins on behalf of Wisconsin Fertility Institute. Each abstract describes a retrospective cohort study, and the findings warrant confirmation in larger, prospective investigations.
AGE AND OVARIAN RESERVE INFLUENCE RESPONSE TO OVARIAN PLATELET-RICH PLASMA IN IVF CYCLES
KEY FINDINGS AND CONCLUSIONS: Among 19 patients, those younger than 35 years (n = 3) demonstrated the most robust improvements in ovarian response, including higher oocyte yield and improved embryo development. Patients ages 35-39 (n = 9) showed moderate but generally consistent improvements, while patients age 40 and older (n = 7) experienced more limited responses and continued to demonstrate high rates of aneuploidy. The abstract concludes that response to ovarian PRP appears to be influenced by age and underlying ovarian reserve; while ovarian responsiveness may improve across age groups, embryo competence remains largely age-dependent, highlighting the importance of patient selection.
OVARIAN PLATELET-RICH PLASMA IS ASSOCIATED WITH DE NOVO EUPLOID EMBRYO DEVELOPMENT AND SPONTANEOUS CONCEPTION IN PATIENTS WITH PRIOR POOR IVF OUTCOMES
KEY FINDINGS AND CONCLUSIONS: In a 19-patient analysis in which each patient served as her own control, the study reported an overall increase in high-quality blastocyst development following PRP. Two patients moved from producing no euploid embryos to producing multiple euploid embryos in subsequent cycles, and two patients conceived spontaneously while preparing for additional IVF treatment. Patients of advanced maternal age continued to demonstrate high aneuploidy rates. The abstract concludes that ovarian PRP may be associated with improved embryo competence and euploid embryo development in select patients with prior poor IVF outcomes and that the observations warrant further prospective investigation.
OVARIAN PLATELET-RICH PLASMA CONVERTS PREVIOUSLY NONPRODUCTIVE OR CANCELLED IVF CYCLES INTO VIABLE RETRIEVALS IN POOR RESPONDERS
KEY FINDINGS AND CONCLUSIONS: Among 17 evaluable patients, baseline antral follicle count increased in 9, oocyte yield increased in 11, and mature oocyte counts increased in 10 following PRP. Three patients with prior cycle cancellation or extremely poor response were able to proceed to oocyte retrieval, and 3 of 5 patients who had previously produced no embryos demonstrated embryo development in subsequent cycles. The abstract concludes that ovarian PRP may enhance ovarian responsiveness and facilitate retrieval in patients with prior poor response or cancelled cycles, potentially offering an adjunctive option for a population with otherwise limited treatment success.
SUBENDOMETRIAL PLATELET-RICH PLASMA IMPROVES EMBRYO TRANSFER FEASIBILITY AND PREGNANCY OUTCOMES IN PATIENTS WITH POOR ENDOMETRIAL DEVELOPMENT
KEY FINDINGS AND CONCLUSIONS: Prior to PRP, 2 of 9 patients (

KEY FINDINGS AND CONCLUSIONS: Endometrial thickness improved in 8 of 9 patients (
About INVO Fertility
We are a healthcare services fertility company dedicated to expanding access to assisted reproductive technology ("ART") care to patients in need. Our principal commercial strategy is focused on building, acquiring, and operating fertility clinics, including "INVO Centers" dedicated primarily to offering the intravaginal culture ("IVC") procedure enabled by our INVOcell® medical device ("INVOcell") and U.S.-based, profitable in vitro fertilization ("IVF") clinics.
We have four operational fertility clinics in the United States. We also continue to engage in the sale and distribution of INVOcell to third-party owned and operated fertility clinics. INVOcell is a proprietary and revolutionary medical device, and the first to allow fertilization and early embryo development to take place in vivo within the woman's body. The IVC procedure provides patients with a more connected, intimate, and affordable experience in comparison to other ART treatments.
We believe the IVC procedure can deliver comparable results at a fraction of the cost of traditional IVF and is a significantly more effective treatment than intrauterine insemination. For more information, please visit invofertility.com.
