Can autologous platelet rich plasma expand endometrial thickness and improve pregnancy rate during frozen-thawed embryo transfer cycle? A randomized clinical trial
[OBJECTIVE] One of the important aspects involved in achieving optimal outcomes after assisted reproductive treatment (ART) is the endometrium. Some cycles are cancelled due to inadequate endometrial growth in ART. In this clinical trial, we evaluated the effectiveness of platelet-rich plasma (PRP) in the treatment of thin endometrium. [MATERIALS AND METHODS] In this randomized clinical trial, 83 women with poor endometrial response to standard hormone replacement therapy (HRT) (endometrium thickness < 7 mm) in the 13th day of the cycle in a frozen-thawed embryo transfer (FET) were entered in two groups. In the PRP group (n = 40), in addition to HRT, 0.5-1 cc of PRP was infused into the uterine cavity on the 13th day of HRT cycle. The control group (n = 43) was only received HRT. If endometrial thickness failed to increase after 48 h, PRP infusion was repeated in the same cycle. When the endometrium thickness reached ≥7 mm, embryo transfer was done. Finally, endometrial thickness, chemical, clinical, and ongoing pregnancy rates were compared between two groups. [RESULTS] Endometrial thickness increased significantly to 8.67 ± 0.64 in PRP group than in controls (p = 0.001). This increase was higher in women who conceived in PRP group (p value: 0.031). The implantation rate and per-cycle clinical pregnancy rate were significantly higher in PRP group (p = 0.002 and 0.044, respectively (p = 0.002). [CONCLUSION] PRP may be effective in improving the endometrial growth, and possibly pregnancy outcomes in women with a thin endometrium.

Endometrial receptivity (ER) is a key factor required for the successful implantation of the embryo. However, the evaluation of ER is challenging, as a nondisruptive sampling of endometrial biomaterial by conventional methods is only possible outside of the embryo transfer (ET) cycle. We propose a novel approach for the assessment of ER-microbiological and cytokine profiling of menstrual blood aspirated directly from the uterine cavity at the beginning of the cryo-ET cycle. The aim of the pilot study was to evaluate its prognostic potential regarding the outcome of the in vitro fertilization procedure. Samples collected from a cohort of 42 patients undergoing cryo-ET were analyzed by a multiplex immunoassay (48 various cytokines, chemokines, and growth factors) and a real-time PCR assay (28 relevant microbial taxa and 3 members of the Herpesviridae family). Significant differences between groups of patients who achieved and did not achieve pregnancy were observed for G-CSF, GRO-α, IL-6, IL-9, MCP-1, M-CSF, SDF-1α, TNF-β, TRAIL, SCF, IP-10, and MIG (p < 0.05), whereas microbial profiles were not associated with the outcome of cryo-ET. It appeared that levels of IP-10 and SCGF-β were significantly lower (p < 0.05), in patients with endometriosis. Menstrual blood may provide great opportunities to noninvasively investigate various parameters of the endometrium.
Tamoxifen has played a vital role in endocrine therapy for the treatment of estrogen receptor-positive breast cancer. We examined the effect of tamoxifen in patients with a thin endometrium in frozen-thawed embryo transfer (FET) cycles and compared the improvement in endometrial thickness (EMT) and pregnancy outcomes stratified by different etiologies of thin endometrium. A total of 226 women were recruited for a new tamoxifen protocol; all had an EMT of less than 7.5 mm in previous cycles, including natural cycle (NC), hormone replacement treatment (HRT), and ovulation induction (OI) cycles. Compared with previous cycles, tamoxifen cycles showed a significantly increased EMT (from 6.11 ± 0.98 mm to 7.87 ± 1.48 mm in the NC group, from 6.24 ± 1.01 mm to 8.22 ± 1.67 mm in the HRT group, and from 6.34 ± 1.03 mm to 8.05 ± 1.58 mm in the OI group; all P < .001). Patients were further divided into 3 groups based on the causes of their thin endometrium: (1) history of intrauterine adhesion (n = 34), (2) history of uterine curettage (n = 141), and (3) polycystic ovary syndrome (PCOS; n = 51). Patients with PCOS obtained the thickest EMT (9.31 ± 1.55 mm), the lowest cycle cancellation rate (11.76%), and the highest rate of clinical pregnancy (60%) and live birth (55.56%) per transfer ( P < .001). Multivariable regression analysis showed that EMT was related to live birth (odds ratio: 1.487; 95% confidence interval: 1.172-1.887). A tamoxifen protocol improves EMT in patients after NC, HRT, and OI cycles during FET. Patients with PCOS show the most benefit from tamoxifen and achieve better pregnancy outcomes.
[OBJECTIVE] The role of intrauterine PRP infusion in managing recurrent implantation failure (RIF) remains controversial despite its emerging clinical use. This systematic review aims to evaluate its therapeutic potential in RIF patients and further to investigate variations in outcomes based on transfer cycle type, embryo developmental stage, RIF diagnostic criteria, and endometrial thickness. [METHODS] We systematically searched MEDLINE, Embase, the Cochrane Central Register of Controlled Trials, Scopus, and Web of Science for randomized controlled trials (RCTs) investigating PRP treatment for RIF patients from the beginning of the database to May 2025. [RESULTS] This meta-analysis showed that PRP administration significantly improved clinical pregnancy rate (CPR) [OR = 3.18, 95%CI (2.45, 4.14), I2 = 3%], biochemical pregnancy rate (BPR) [OR = 2.84, 95%CI (2.22, 3.63), I2 = 0%], ongoing pregnancy rate (OPR) [OR = 3.41, 95%CI (2.08, 5.60), I2 = 30%] and live birth rate (LBR) [OR=5.10, 95%CI (1.95, 13.37), I2 = 75%] in women with RIF. However, PRP intrauterine infusion did not reduce miscarriage rate (MR). Notably, the preterm birth rate was significantly higher in the PRP group compared to controls [OR = 8.24, 95%CI (2.09, 32.41), I2 = 0%]. Subgroup analysis demonstrated that PRP improved CPR, BPR and LBR in both the fresh and frozen embryo transfer cycles. Additionally, while PRP increased CPR, LBR and reduced MR in blastocyst transfers [CPR OR = 3.84, 95%CI (2.82, 5.23), I2 = 0%; LBR OR = 7.32, 95%CI (3.17, 16.90), I2 = 63%; MR OR = 0.27, 95%CI (0.07, 0.96), I2 = 54%], these effects were not observed in cleavage-stage embryo transfers. Moreover, PRP administration associated with a higher CPR [OR = 3.84, 95%CI (2.82, 5.23), I2 = 0%], OPR[OR = 4.13, 95%CI (1.79, 9.56), I2 = 48%], LBR [OR = 7.32, 95%CI (3.17, 16.90), I2 = 63%] and a lower MR [OR = 0.27, 95%CI (0.07, 0.96), I2 = 54%] in women with ≥3 prior implantation failure, it did not confer the same benefit to those with a history of ≥2 failed cycles. [CONCLUSION] These findings suggest a possible beneficial role for PRP on pregnancy outcomes to some extent in women with RIF, particularly in cases with ≥3 prior failed transfers, and blastocyst transfer may increase LBR and reduce miscarriage risk. However, further investigation is warranted to determine whether this treatment may pose an increased risk of preterm birth.

Premature ovarian insufficiency (POI) severely limits reproductive options. We report a successful live birth in a patient with POI following a combined approach of intraovarian platelet-rich plasma (PRP) treatment, double ovarian stimulation (DuoStim protocol), and preimplantation genetic testing for aneuploidy (PGT-A). PRP treatment was performed to restore ovarian function, after which DuoStim was used to maximize oocyte yield. An embryo obtained underwent PGT-A, and transfer of a euploid blastocyst resulted in an uncomplicated pregnancy and the birth of a healthy child. This case highlights the potential of personalized and multidisciplinary strategies to overcome the traditional barriers in POI by integrating regenerative medicine (PRP), advanced ovarian stimulation (DuoStim), and genetic embryo selection (PGT-A). While this innovative approach appears promising for women with diminished ovarian reserve, further studies are needed to confirm its efficacy and safety.
