OBJECTIVE To evaluate the value of intrauterine platelet-rich concentrates among patients with intrauterine adhesions (IUAs) after hysteroscopic adhesiolysis. METHODS Four different databases (PubMed, Cochrane Library, Scopus, and ISI web of science) were searched for the available studies from inception to November 2021. We selected randomized clinical trials (RCTs) that compared platelet-rich concentrates in the intervention group versus no injection of platelet-rich concentrates in the control group among women with intrauterine adhesions after operative hysteroscopy. Revman software was utilized for performing our meta-analysis. Our primary outcomes were the adhesion score and incidence of recurrence of severe intrauterine adhesions postoperatively. Our secondary outcomes were the clinical pregnancy rate, menstrual flow duration in days, and menstrual flow amount (number of pads). RESULTS Five RCTs met our inclusion criteria with a total number of 329 patients. We found that platelet-rich concentrates were linked to a significant reduction in the postoperative adhesion score (MD = -1.00, 95% CI [-1.68, -0.32], p = 0.004). Moreover, there was a significant reduction in the incidence of severe IUAs recurrence among the platelet-rich concentrates group (7.6%) compared to the control group (23.4%) after hysteroscopy (p = 0.001). The clinical pregnancy rate was significantly increased among the platelet-rich concentrates group (37.1%) in comparison with the control group (20.7%) after hysteroscopic adhesiolysis (p = 0.008). There were significant improvements in the menstrual flow duration and amount among the platelet-rich concentrates group (p < 0.001). CONCLUSIONS Intrauterine placement of platelet-rich concentrates is an effective method for the treatment of intrauterine adhesions after hysteroscopy.

(1) Background: Controversial conclusions have been made in previous studies regarding the influence of autologous platelet-rich plasma (PRP) in the reproductive outcomes of women with repeated implantation failures (RIF) who are undergoing embryo transfer (ET). (2) Methods: This study aimed to evaluate the effect of PRP intrauterine infusion in patients with unexplained RIF, who are undergoing in vitro fertilization (IVF) or intracytoplasmic injection (ICSI), by a systematic review and meta-analysis. (3) Results: A fixed-effects model was used, and 795 cases and 834 controls were included in these studies. The pooling of the results showed the beneficial effect of PRP which were compared with those of the control in terms of the clinical pregnancy rates (n = 10, risk ratio (RR) = 1.79, 95% confidence intervals (CI): 1.55, 2.06; p < 0.01, I(2) = 40%), live birth rates (n = 4, RR = 2.92, 95% CI: 2.22, 3.85; p < 0.01, I(2) = 83%), implantation rates (n = 3, RR = 1.74, 95% CI: 1.34, 2.26; p < 0.01, I(2) = 0%), and positive serum β-HCG 14 days after the ET (n = 8, RR = 1.77, 95% CI: 1.54, 2.03; p < 0.01, I(2) = 36%). However, we did not find that the miscarriage rates indicated a significant difference between the two groups (n = 6, RR = 1.04, 95% CI: 0.72, 1.51; p = 0.83, I(2) = 0%). (4) Conclusions: The findings of this systemic review and meta-analysis suggest that PRP appears to improve the results of IVF/ICSI treatments in the cases of unexplained RIF.

This study evaluated the effect of intrauterine perfusion of autologous platelet-rich plasma (PRP) on pregnancy outcomes in women with recurrent implantation failure (RIF). Key biomedical databases were searched to identify relevant clinical trials and observational studies. Outcomes included clinical pregnancy rate, chemical pregnancy rate, implantation rate, live birth rate, and abortion rate. Data was extracted from ten studies (six randomised controlled trials, four cohort studies) involving 1555 patients. Pregnancy outcomes were improved in women treated with PRP compared to controls: clinical pregnancy rate (RR = 1.96, 95% CI [1.67, 2.31], p < 0.00001, I(2) = 46%), chemical pregnancy rate (RR = 1.79, 95% CI [1.54, 2.08], p < 0.00001, I(2) = 29%), implantation rate (RR = 1.90, CI [1.50, 2.41], p < 0.00001, I(2) = 0%), live birth rate (RR = 2.83, CI [1.45, 5.52], p = 0.0007, I(2) = 83%), abortion rate (RR = 0.40, 95% CI [0.18, 0.90], p = 0.03, I(2) = 59%). These data imply PRP has potential to improve pregnancy outcomes in women with RIF, suggesting a promising role in assisted reproductive technology.IMPACT STATEMENTWhat is already known on this subject? Platelet-rich plasma (PRP) is an autologous blood product that contains platelets, various growth factors, and cytokines at concentrations above the normal baseline level. Recent studies have shown that intrauterine infusion of autologous PRP can improve pregnancy outcomes in infertile women.What do the results of this study add? This systematic review and meta-analysis of data from ten studies (n = 1555; 775 cases and 780 controls) investigated the effect of intrauterine perfusion of autologous PRP on pregnancy outcomes in women with recurrent implantation failure (RIF). Findings suggest that pregnancy outcomes, including clinical pregnancy rate, chemical pregnancy rate, implantation rate, live birth rate and abortion rate were improved in women treated with PRP compared to controls.What are the implications of these findings for clinical practice and/or further research? RIF remains a challenge for researchers, clinicians, and patients. Our study identified PRP as a potential intervention in assisted reproduction. As an autologous blood preparation, PRP eliminates the risk of an immune response and transmission of disease. PRP is low cost and effective and may represent a new approach to the treatment of patients with RIF.

AIMS: Previous studies have reported inconsistent findings on the efficacy of platelet-rich plasma (PRP) therapy in women with implantation failure. The objective of this review was to evaluate whether PRP administration could improve pregnancy outcomes in women with implantation failure undergoing in vitro fertilization. METHODS Electronic databases were searched for studies that explored the effects of PRP for patients with implantation failure. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated. Based on the available data, we performed subgroup analyses and sensitivity analyses. RESULTS Eight studies were included. PRP treatment improved pregnancy outcomes for all women compared with no treatment or placebo (clinical pregnancy rate: OR 2.24, 95% CI 1.41-3.54; live birth rate: OR 5.76, 95% CI 1.55-21.44; miscarriage rate: OR 0.18, 95% CI 0.05-0.63), especially in randomized controlled trials. No significant differences were detected in multiple pregnancy rates (OR 2.54, 95% CI 0.67-9.67). Furthermore, subgroup analysis based on the number of previous implantation failures showed that PRP treatment improved pregnancy outcomes in women with recurrent implantation failure (clinical pregnancy rate: OR 2.55, 95% CI 1.49-4.38; live birth rate: OR 5.07, 95% CI 1.15-22.34; miscarriage rate: OR 0.20, 95% CI 0.05-0.78). CONCLUSION PRP administration could improve pregnancy outcomes in women with recurrent implantation failure. Due to the limited evidence available, the efficacy of PRP in women with recurrent implantation failure needs to be further verified in high-quality studies with larger sample sizes.

OBJECTIVE To conduct a systematic review and meta-analysis to assess the efficacy of platelet-rich plasma (PRP) infusion after adhesiolysis in patients with intrauterine adhesions (IUAs) by establishing the evidence from published randomized controlled trials (RCTs). METHODS PubMed, Scopus, Web of Science, Cochrane Central Register of Controlled Trials (CENTRAL), and Google Scholar databases were screened from inception till June 2021. Risk of bias of included studies was evaluated according to the Cochrane's Collaboration tool. The efficacy endpoints were summarized as risk ratio (RR) or mean difference (MD) with 95% confidence interval (CI) under the fixed-effects model. RESULTS Three RCTs met the inclusion criteria, comprising a total of 260 patients (132 and 128 patients were allocated to PRP and control groups, respectively). The RCTs revealed an overall low risk of bias. Compared with the control group, the PRP group had a statistically significant higher rate of patients with IUAs grade I-II after intervention (n=3 RCTs, RR=1.23, 95% CI [1.11 to 1.36], p<0.001), higher duration of menstrual menses after intervention (n=3 RCTs, MD=1.13 days, 95% CI [0.86 to 1.41], p<0.001), and higher amount of menstrual menses after intervention (n=3 RCTs, MD=2.96 pads, 95% CI [0.31 to 3.61], p<0.001). All pooled analyses were homogeneous. CONCLUSION PRP treatment after hysteroscopic adhesiolysis is effective in decreasing the IUA grade and improving the duration and amount of menstrual menses. Nonetheless, additional RCTs are warranted to validate these conclusions.

PURPOSE Platelet-rich plasma (PRP) has become a novel treatment in various aspects of medicine including orthopedics, cardiothoracic surgery, plastic surgery, dermatology, dentistry, and diabetic wound healing. PRP is now starting to become an area of interest in reproductive medicine more specifically focusing on infertility. Poor ovarian reserve, menopause, premature ovarian failure, and thin endometrium have been the main areas of research. The aim of this article is to review the existing literature on the effects of autologous PRP in reproductive medicine providing a summation of the current studies and assessing the need for additional research. METHODS A literature search is performed using PubMed, MEDLINE, and CINAHL Plus to identify studies focusing on the use of PRP therapy in reproductive medicine. Articles were divided into 3 categories: PRP in thin lining, PRP in poor ovarian reserve, and PRP in recurrent implantation failure. RESULTS In women with thin endometrium, the literature shows an increase in endometrial thickness and increase in chemical and clinical pregnancy rates following autologous PRP therapy. In women with poor ovarian reserve, autologous intraovarian PRP therapy increased anti-Mullerian hormone (AMH) levels and decreased follicle-stimulating hormone (FSH), with a trend toward increasing clinical and live birth rates. This trend was also noted in women with recurrent implantation failure. CONCLUSIONS Limited literature shows promise in increasing endometrial thickness, increasing AMH, and decreasing FSH levels, as well as increasing chemical and clinical pregnancy rates. The lack of standardization of PRP preparation along with the lack of large randomized controlled trials needs to be addressed in future studies. Until definitive large RCTs are available, PRP use should be considered experimental.

Asherman syndrome (AS) consists of intrauterine adhesions development as a consequence of trauma, radiation, or infection in the endometrium. Clinical symptoms include menstrual alterations, infertility, and pregnancy complications, such as recurrent pregnancy loss or abnormal placentation. In this article, we performed a narrative review of the literature, searching electronic databases (i.e., Medline, Pubmed, and Google Scholar) to summarize the available pieces of evidence about epidemiology, pathophysiology, diagnosis, and treatment of AS. Hysteroscopy is essential for diagnosis and treatment, although adhesions may recur. Different postoperative therapies have been proposed to prevent recurrence and restore impaired endometrial function and promote endometrial regeneration, although these effects are usually temporary. We report a case of AS with adhesion recurrence and endometrial atrophy who was successfully treated with intrauterine autologous platelet-rich plasma (PRP) infusion. This therapy allowed endometrial tissue regeneration, leading to increased vascularity and endometrium thickness, and restoration of endometrial function that led to a successful pregnancy. Though there is limited experience supporting the use of PRP to improve endometrial function, it has been safely used in other fields of medicine; besides, it is easy to obtain, not expensive, and harmless being an autologous source. Future studies are encouraged to further assess this approach to treat AS.
A Systematic Review Evaluating the Efficacy of Intra-Ovarian Infusion of Autologous Platelet-Rich Plasma in Patients With Poor Ovarian Reserve or Ovarian Insufficiency
Panda SR, Sachan S, Hota S
The emergence of autologous platelet-rich plasma (PRP) therapy reflects a break-through for infertile patients with premature ovarian failure. To study the efficacy of intra-ovarian infusion of autologous PRP on the improvement of ovarian reserve parameters and the subsequent artificial reproductive technique (ART) cycle outcomes in infertile women with poor ovarian reserve or premature ovarian insufficiency, a systematic search in electronic databases like Medline (through PubMed), Embase, Scopus, Web of Science, and Cochrane was done using relevant search terms. Except for case series, case reports, and review articles, all other types of studies, those evaluated for the effects of intra-ovarian infusion of PRP in subfertile women for decreased ovarian reserve (DOR) or premature ovarian insufficiency (POI) were included in our systematic review. The data were extracted from each eligible study and cross-checked by two authors. Intra-ovarian PRP infusion appears to be effective in ovarian rejuvenation, and the results of the subsequent intracytoplasmic sperm injection (ICSI) cycle are encouraging. PRP intervention was found to be beneficial in terms of an improvement in ovarian reserve parameters (increase in serum anti-mullerian hormone or antral follicle count or decrease in serum follicular stimulating hormone). ICSI cycle performance in terms of the total number of oocytes retrieved, number of two-pronuclei embryos, fertilization rate, number of cleavage stage embryos, number of good quality embryos, and cycle cancellation rate were found to be improved after intra-ovarian PRP infusion as compared to their previous cycle without PRP infusion.

Prior studies have provided conflicting results regarding the use of platelet-rich plasma (PRP) in women undergoing in-vitro fertilization (IVF) or intracytoplasmic injection (ICSI). The objective of this study was to evaluate the effect of the intrauterine infusion of PRP on the outcome of embryo transfer (ET) in women undergoing IVF/ICSI. We searched databases, including PubMed, Embase, Scopus, Web of Science, and the Cochrane Database of Clinical Trials (CENTRAL). Meta-analysis using a random-effects model was performed to calculate the pooled estimates. Seven studies involving 625 patients (311 cases and 314 controls) were included. The probability of chemical pregnancy (n=3, risk ratio (RR): 1.79, 95 % confidence intervals (CI): 1.29, 2.50; P<0.001, I(2)=0 %), clinical pregnancy (n=7, RR: 1.79, 95 % CI: 1.37, 2.32; P<0.001, I(2)=16 %), and implantation rate (n=3, RR: 1.97, 95 % CI: 1.40, 2.79; P<0.001, I(2)=0 %) was significantly higher in women who received PRP compared with control. There was no difference between women who received PRP compared with control group regarding miscarriage (RR: 0.72, 95 % CI: 0.27, 1.93; P=0.51, I(2)=0 %). Following the intervention, endometrial thickness increased in women who received PRP compared to control group (SMD: 1.79, 95 % CI: 1.13, 2.44; P<0.001, I(2)=64 %). The findings of this systematic review suggest that PRP is an alternative treatment strategy in patients with thin endometrium and recurrent implantation failure (RIF). Further prospective, large, and high quality randomized controlled trials (RCTs) are needed to identify the subpopulation that would most benefit from PRP.

Journal of Lower Genital Tract Disease. 2018;23((1):):65-70.
OBJECTIVE The aim of the study was to summarize and review the evidence for the efficacy and safety of adipose-derived stem cells (ADSCs) and platelet-rich plasma (PRP) for the treatment of vulvar lichen sclerosus (LS). MATERIALS AND METHODS PubMed/MEDLINE, Ovid, Web of Science, and clinicaltrials.gov were searched from inception up to May 7, 2018. RESULTS Seven observational studies were identified, with a total of 98 patients. Both ADSCs and PRP were reported to improve symptoms, quality of life measures, as well as clinical and histological signs of vulvar LS. There is a strong risk of biased estimates of treatment effect. CONCLUSIONS Current evidence is weak for ADSCs and/or PRP as treatment for vulvar LS. Further research is needed before recommending this therapy.
