Abstract
BACKGROUND Platelet-rich plasma (PRP) is a therapeutic approach that is gaining attention for its potential in the treatment of poor ovarian response. This meta-analysis aimed to systematically review and analyze clinical studies to evaluate the impact of PRP on poor responders undergoing ovarian stimulation for IVF. METHODS A comprehensive search was conducted in electronic databases, including PubMed, Embase, Scopus, Web of Science, and the Cochrane Library to identify relevant studies published in English. The pooled data, such as pregnancy outcome, number of MII oocytes, number of transferable embryos, and ovarian reserve markers were analyzed using R version 4.2.3. RESULTS A total of 10 trials were enrolled in the present meta-analysis. Following PRP treatment, live birth rate was found to be 16.6% (95% CI 8.8%-26.1%), while clinical pregnancy rate was observed to be 25.4% (95% CI 13.1%-39.9%). PRP pretreatment resulted in a higher number of MII oocytes (MD 1.073, 95% CI 0.720 to 1.427), a higher number of embryos (MD 0.946, 95% CI 0.569 to 1.323), a higher antral follicle count (MD 1.117; 95% CI 0.689 to 1.544), and the change of hormone levels. CONCLUSIONS Among the studies evaluated in this review, PRP showed promising results in poor responder. Further research is required to clarify the potential role of PRP in female reproductive health. What is the context? The incidence of poor ovarian response following ovarian stimulation ranges globally from 5.6% to 35.1%.Although various interventions have been implemented in patients with POR, there is a lack of empirical evidence demonstrating the superiority of any of these therapies over one another.Platelet-rich plasma, which is rich in growth factors that have been implicated in cellular growth, differentiation, angiogenesis, and tissue repair, is emerging as a promising therapeutic modality.Limited data determines the viability of PRP as an alternative therapy for POR patients, but further evidence is needed to quantify this effect.What is new? To the best of our knowledge, this is the first systematic review and meta-analysis that investigated the efficacy of PRP on women with POR, including ten trials and 876 patients.This review provides a comprehensive overview of the existing evidence on the utilization of PRP in poor responders, while also emphasizing the primary limitations in the literature and the necessity for future research based on evidence.What is the impact? Among the studies evaluated in this review, PRP showed a potential positive impact on the regulation of sex hormone levels, ovarian response, and pregnancy outcomes. eng

Eftekhar, M., Neghab, N., Khani, P.
International journal of fertility & sterility. 2024;18(2):162-166
Abstract
BACKGROUND Platelet-rich plasma (PRP) therapy has been shown to enhance tissue regeneration by expressing several cytokines and growth factors (GFs). This study investigated the effect of intrauterine infusion of PRP as a noninvasive autologous GF on pregnancy outcomes in women with repeated implantation failure. MATERIALS AND METHODS This randomized clinical trial was conducted to compare the pregnancy rates between two groups of women who were candidates for the frozen-thawed embryo transfer with a history of two or more implantation failures. The PRP group (n=33) was treated with hormone replacement therapy+0.5 cc to 1 cc PRP infused into the uterine cavity two days before the embryo transfer. The control group (n=33) was only treated with hormone replacement therapy. The endometrial preparation process was done similarly in both groups. The chemical, clinical, and ongoing pregnancy, and implantation rates were compared between the two groups. RESULTS Our results showed that the chemical pregnancy rate was not statistically higher in the PRP group in comparison with the control group (36.4 vs. 24.2%). In addition, the clinical pregnancy, ongoing pregnancy, and implantation rates were higher in the PRP group than the control group; however, the difference between the two groups was not statistically significant. CONCLUSION Administration of intrauterine PRP before embryo transfer in women with repeated implantation failure (RIF) does not affect assisted reproductive technology (ART) outcomes (registration number: IRCT2016090728950N3).

Abstract
Assisted reproductive technology (ART) is used to enhance pregnancy in infertile women. In this technique, the eggs are removed from the ovary and fertilized and injected with sperm to make embryos. Unfortunately, embryo implantation failures still occur in many of these women. Platelet-rich plasma (PRP) therapies use a patient's own platelets to promote tissue healing and growth, including endometrium. The growth factors provided by the platelets play a criterial role on the regenerative ability of PRP. In the last years, PRP treatments have been gaining a lot of popularity to treat women with repeated ART failures. In this study, we collected and summarized all information published in the scientific literature to assess the evidence of the PRP effect on pregnancy. We only considered randomized controlled trials (RCT), a type of study designed to be unbiased and considered at the highest level of evidence. Our analysis indicates that PRP therapies might be an effective treatment in cases of poor responsiveness to conventional ART. However, additional studies (well-designed) are necessary to confirm this beneficial effect of PRP.

Abstract
PURPOSE Intrauterine adhesion (IUAs) in women is a debatable topic and there is no clear consensus in its management and treatment strategies. Previous treatment measures have limitations which necessitates to consider effective measures for prevention of recurrence of IUAs. Hence, the aim of this study to explore the efficacy and safety of intrauterine infusion of autologous platelet gel (APG) and medical chitosan in preventing recurrence of IUAs in females after transcervical resection of adhesion (TCRA). METHODS A prospective, randomized controlled trial was conducted among 80 patients presented with moderate to severe IUAs. Patients were randomized into two groups, APG group (n = 40) and medical chitosan group (n = 40). All patients were injected with either APG or medical chitosan after TCRA. RESULTS The postoperative recurrence rate of adhesions in APG group was significantly lower than those in medical chitosan group (21% vs 49%). The median AFS score during the second-look hysteroscopy was significantly lower in APG group than in medical chitosan group (P = 0.008). The median AFS score reduction after TCRA surgery was significantly higher in APG group than in medical chitosan group (median, 95% CI 7.000, 6.0 to 8.3 vs. 6.000, 5.0 to 7.0, P = 0.004). Subgroup analysis of platelet concentration (1000 as cut-off value) into high- and low-dose subgroups reported no significant correlation existed between APG and baseline characteristics, recurrence rate and postoperative AFS reduction score except for previous intrauterine operation (P < 0.05). CONCLUSION Thus, after TCRA, intrauterine injections of APG provides better efficacy and safety compared with intrauterine injections of medical chitosan in preventing recurrence of intrauterine adhesions.

Abstract
IMPORTANCE Urinary incontinence affects millions of women worldwide. OBJECTIVE The aim of the current study was to evaluate the efficacy and safety of periurethral platelet-rich plasma (PRP) injections in women with stress urinary incontinence (SUI). STUDY DESIGN This was a single-center, double-blind, randomized sham-controlled trial. Fifty participants with SUI and urodynamic stress incontinence were randomized in 2 equally sized groups. Women in the PRP group received 2 PRP injections at 3 levels of the urethra at 4- to 6-week intervals. Women in the sham group were injected with sodium chloride 0.9%. At baseline, participants underwent urodynamic studies and a 1-hour pad test and completed the International Consultation on Incontinence Questionnaire-Female Lower Urinary Tract Symptoms (ICIQ-FLUTS), the Patient Global Impression Scale of Improvement, and the King's Health Questionnaire. At follow-up visits (1, 3, and 6 months), women underwent the 1-hour pad test and completed the King's Health Questionnaire and the ICIQ-FLUTS. Primary outcome was the subjective evaluation as indicated by the response to question 11a of the ICIQ-FLUTS questionnaire. Secondary outcomes included scores of questionnaires and urine loss assessed on the 1-hour pad test. The level of discomfort during injections and any adverse events were also evaluated. RESULTS During follow-up, the mean score of the 11a question decreased significantly in the PRP group compared with sham. Subjective cure was significantly higher in the PRP group (32% vs 4%, P < 0.001). A significant reduction of urine loss assessed on the 1-hour pad test was observed in the PRP group compared with the sham group at 6-month follow-up. No adverse events were observed. CONCLUSIONS Periurethral PRP injections were superior to sham injections in improving SUI symptoms with an excellent safety profile.

Abstract
Introduction: There is no clear evidence in the literature that platelet-rich plasma (PRP) injections improve female sexual dysfunction (FSD) and female stress urinary incontinence (SUI). Objectives: A systematic review was performed to study the efficacy and safety of PRP injections in women with the above pathologies, as well as to explore the optimal dosing, frequency and area of injections, and duration of treatment. Methods: A systematic search on PubMed, Embase and the Cochrane Library database was performed, as well as sources of grey literature from the date of database or source creation to January 2023. After title/abstract and full-text screening, clinical studies on humans evaluating the efficacy of PRP in gynecological disorders using standardized tools were included. Risk of bias was undertaken with RoB-2 for randomized-controlled trials (RCT) and the Newcastle-Ottawa Scale (NOS) for observational studies. Results: Four prospective and one retrospective study explored FSD, while six prospective and one RCT evaluated female SUI. A total of 327 women with a mean age of 51 ± 12 years were included. For FSD, PRP significantly improved the Female Sexual Function Index (FSFI), the Vaginal Health Index (VHI) and the Female Sexual Distress score (FSDS). For SUI, PRP led to a significant improvement in the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF) and the Urogenital Distress Inventory (UDI-6). The identified RCT reported a significantly higher mean score of ICIQ-SF (p < 0.05) and UDI-6 (p < 0.01) in the midurethral sling group compared to the PRP injections group. Regarding the risk of bias, the RCT was characterized by high risk, whereas the observational studies were of moderate risk. The protocol for PRP injections for FSD is the injection of 2 mL of PRP into the distal anterior vaginal wall once a month for 3 months. For female SUI, 5-6 mL of PRP should be injected into the periurethral area once a month for 3 months. Conclusions: Despite the promising initial results of PRP injections, the level of current evidence is low due to methodological issues in the available studies. It becomes clear that there is an emerging need for high-quality research examining PRP injections for the treatment of FSD and female SUI.

Abstract
IMPORTANCE Autologous platelet-rich plasma (A-PRP) injection is a novel intervention for stress urinary incontinence (SUI) in women. However, no Phase II clinical trial has compared the outcomes of A-PRP injection combined with pelvic floor muscle training (PFMT) with those of PFMT alone in these women. OBJECTIVE The primary aim was to compare the efficacy of A-PRP + PFMT versus PFMT alone in women with SUI. The secondary aim was to determine any adverse effects of A-PRP injection. DESIGN Randomized clinical trial, single-blind assessment. SETTING Urogynecology clinic at a tertiary medical center. PARTICIPANTS Women with previously untreated SUI. Women in whom there was any suspicion of urgency, those with an Overactive Bladder Symptoms Score of ≥1, and those with obesity, pelvic organ prolapse, thrombocytopenia, or coagulopathy were excluded. INTERVENTIONS Two injections of A-PRP were administered with a 1-month interval between injections in the A-PRP injection + PFMT group. Both groups received PFMT. MAIN OUTCOMES AND MEASURES The primary outcome was determined using the 1-h pad weight test (PWT). Secondary outcomes were measured using the Incontinence Quality of Life Questionnaire, item 11 on the International Consultation on Incontinence Questionnaire-Female Lower Urinary Tract Symptoms questionnaire, Patient Global Impression of Improvement, and the percentage subjective improvement score. RESULTS Data for 60 study participants were available for analysis (A-PRP + PFMT group, n = 31; PFMT group, n = 29). The 1-h PWT decreased significantly in the A-PRP + PFMT group but only slightly in the PFMT group at the 5-month follow-up. There was a statistically significant between-group difference in the 1-h pad weight of about 8 g in favor of the A-PRP + PFMT group. A statistically significant difference in symptoms of SUI measured by the questionnaires was found between the A-PRP + PFMT group and the PFMT group at the 2- and 5-month follow-up assessments. There were no reports of adverse events following injection of A-PRP. CONCLUSIONS AND RELEVANCE A-PRP + PFMT could be a treatment option for women with SUI. Large Phase III randomized controlled trials are required to confirm our findings.

Frontiers in endocrinology. 2023;14:1183209
Abstract
OBJECTIVE This meta-analysis aims to evaluate the efficacy and safety of autologous platelet-rich plasma (PRP) administration in reducing adhesion recurrence and improving pregnancy outcomes in patients with intrauterine adhesion (IUA). METHODS We conducted a comprehensive search of Pubmed, Embase, the Cochrane Library, Web of Science, Scopus, and China National Knowledge Internet (CNKI) from inception to February 10, 2023, without any language or regional restrictions. We used random-effects models to assess odds ratios (OR) and weight mean differences (WMD) with 95% confidence intervals (CI). RESULTS Our meta-analysis included a total of 730 patients from 10 clinical studies (6 RCTs and 4 non-RCTs). The results showed that PRP administration significantly increased endometrial thickness (WMD = 0.79, 95% CI: 0.40-1.19; P < 0.001; I(2) = 0.0%), menstrual volume (WMD = 2.96, 95% CI = 2.30-3.61; P < 0.001; I(2) = 0.0%), and days of menstruation (WMD = 1.13, 95% CI = 0.86-1.41; P < 0.001; I(2) = 0.0%). Additionally, the clinical pregnancy rate was also improved (OR = 1.82, 95% CI: 1.19-2.78; P = 0.006; I(2) = 0.0%). However, there was insufficient evidence to reach a conclusion regarding the effects of PRP on the recurrence rate of moderate to severe IUA, changes in AFS scores, miscarriage rate, and live birth rate. CONCLUSIONS Our analysis confirms that autologous PRP is an effective treatment for IUA. However, the limited sample size suggests that the results should be interpreted with caution. Therefore, larger and well-designed studies are necessary in the future to confirm these findings and explore the optimal PRP dosing regimens further.

AJOG global reports. 2023;3(2):100172
Abstract
BACKGROUND Thin endometrium in infertile female patients has always been a clinical challenge for the treating reproductive physicians. OBJECTIVE This study aimed to evaluate the effect of intrauterine instillation of autologous platelet-rich plasma on endometrial thickness and vascularity in infertile female patients with thin endometrium undergoing ovarian stimulation with intrauterine insemination. STUDY DESIGN This prospective randomized control study included 120 women undergoing ovarian stimulation with intrauterine insemination, aged between 21 and 37 years, with persistent thin endometrium (<7 mm) on ≥1 cycle in previous ovarian stimulation cycles, even after conventional treatment with estradiol valerate. The women were randomly assigned to study group A and control group B. Baseline endometrial thickness and endometrial vascularity were noted. Intrauterine instillation of autologous platelet-rich plasma was done on the day of trigger in group A, whereas estradiol valerate was given in group B. Another evaluation of endometrial parameters was done on the day of intrauterine insemination. The cycle was repeated for 3 cycles or until the pregnancy was achieved, whichever occurred earlier. Parameters were noted for both groups. Primary outcomes were the change in endometrial thickness and endometrial vascularity. Secondary outcomes were positive pregnancy rate and clinical pregnancy rate. RESULTS In group A, mean pre-platelet-rich plasma endometrial thickness was 4.66±0.79 mm, which significantly increased to 7.47±0.85 mm after platelet-rich plasma instillation (P<.05) after 3 cycles. This increase was significantly greater than that observed in group B. There was significant increase in endometrial vascularity in group A compared with group B (P<.05). The positive pregnancy rate and clinical pregnancy rate in group A were 23.73% and 18.64%, respectively, and significantly higher than those in group B. CONCLUSION Autologous platelet-rich plasma is a promising, easily procurable, and novel option for management of infertile females with thin endometrium not responding to conventional treatment. Using it in intrauterine insemination cycles can reduce costs and psychological burden of this subgroup of women by reducing the need for resorting to advanced options such as in vitro fertilization and surrogacy.
