Abstract Background MicroRNAs (miRNAs) are small RNA molecules that modulate post-transcriptional gene regulation. They are often used as promising non-invasive biomarkers for the early diagnosis of cancer. However, their roles in assisted reproduction are still unknown. Methods This prospective study was designed to evaluate the expression profiles of seven extracellular miRNAs (miR-7-5p, miR-202-5p, miR-378-3p, miR-224, miR-320a, miR-212-3p, and miR-21-5p) in human follicular fluid (FF) to explore the outcomes of in vitro fertilization (IVF). Of 255 women, 145 were without polycystic ovary syndrome (PCOS), and their ovarian assets were normal (NOR), while 110 were with normo-androgenic PCOS. Results The combination of six FF miRNAs expression profile discriminated between PCOS and NOR women with a sensitivity of 79.2% and a specificity of 87.32% (AUC = 0.881 [0.61; 0.92], p = 0.001). MiR-202-5p significantly had a lower abundance level, and miR-378-3p had a high abundance level in pooled FF samples from patients treated with human menopausal gonadotropin (hMG) than those treated with recombinant follicle-stimulating hormone (rFSH) (p < 0.001). Our results showed that miRNA-320a was significantly different in top-quality embryos versus non-top-quality embryos on day 3 in NOR patients with a sensitivity of 80% and specificity of 71%, (AUC = [0.753 (0.651; 0.855)], p = 0.001). For clinical pregnancy outcome prediction, FF miRNA-21 exhibited high sensitivity (74.8%) and specificity (83.7%) with the AUC value of 0.774 (0.682; 0.865). Conclusion Conclusively, our results provide evidence that miR-7-5p, miR-378-3p, miR-224, miR-212-3p were a differentially high expression in normo-androgenic PCOS patients than NOR patients. While miRNA-320a was significantly different in top-quality embryos versus non-top-quality embryos on day 3 (p = 0.001). The expression level of FF miR-212-3p was significantly related to the probability of embryos to develop into a high-quality blastocyst in patients with normal ovarian reserve.

The inhibin concentration in 131 samples of human follicular fluid obtained from 31 women undergoing ovarian hyperstimulation for in vitro fertilization was measured using specific double antibody radioimmunoassay. We used the synthetic 1-32-α-inhibin as standard and radioiodinated 1-32-Tyr-α-inhibin as tracer. Antibodies were raised in rabbits by immunization with the synthetic peptide. Estradiol and progesterone concentrations were measured using commercial radioimmunoassays. Results: The inhibin concentration correlated with the estradiol (r = 0.57, N = 88.p<0.0001) and progesterone (r=0.82, N=88. p<0.0001) concentrations in human follicular fluid. The dosage of human menopausal gonadotropin given to individual patients correlated with the average inhibin concentration measured in their follicles (r = 0.72, N = 23, p<0.0001). Similarly, the size of follicles correlated with their inhibin content (r = 0.75, N = 131, p<0.0001). Nineteen samples of human follicular fluid originating from follicles of different size and volume were examined using gel-chromatography. In each human follicular fluid the main form of inhibin (32 kDa) was recovered. In small follicles (3 ml) we found 12.8±9.1% (mean±sd) of the whole immunoreactive inhibin eluating in the area of V0 (≤80 kDa). In the larger follicles (4-7 ml), however, only 4.4±4.2% of this large inhibin form could be found. Conclusions: Our data confirm that human menopausal gonadotropin stimulates ovarian inhibin production. In addition to the estradiol and progesterone concentrations, the inhibin concentration may be an index of granulosa cell function and follicular maturation. The occurrence of large molecular weight forms of inhibin in small follicles remains unclear. They may represent large precursor molecules which are proteolytically cleaved in more mature follicles.

Abstract Background: MicroRNAs (miRNAs) are a class of noncoding small RNAs that play important roles in many physiological processes by regulating gene expression. Previous studies have shown that the expression levels of total miRNAs increase during mouse embryonic development, and some miRNAs control the regulatory network in development progression. However, few studies have focused on the effects of miRNAs on early human embryonic development. The relationship between miRNAs and early human embryogenesis is still unknown. Results:In this study, RNA-seq data collected from sperm samples from 102 patients with a normal sperm index but treated with assisted reproductive technology (ART) were analyzed for the relationships between differentially expressed small RNAs and the fertilization rate (FR), blastocyst rate and high-quality embryo rate (HQER). The sperm samples with high hsa-mir-191 expression had a higher FR, effective embryo rate (EER) and HQER. hsa-mir-191 was used as a single indicator to predict the HQER. The receiver operating characteristic (ROC) curve had an area under the ROC curve (AUC) of 0.686. We also found that hsa-mir-191 expression is correlated with an abnormal sperm rate (cor = 0.29, p< 0.01). We also evaluated the relationship between hsa-mir-34c and early human embryo development in these 102 sperm samples and obtained negative results. Conclusions: These findings suggest that high hsa-mir-191-5p expression in sperm is associated with early human embryonic quality and that hsa-mir-191-5p could be used as a potential marker to screen high-quality sperm to improve the success rates of in vitro fertilization (IVF).
