Abstract (sommario):
The level of nerve growth factor (NGF) in the blood and seminal plasma of asthenozoospermia and oligoasthenozoospermia patients were compared to normozoospermic males and the relationship between NGF with sperm parameters and seminal antioxidant capacity were estimated to determine the role of NGF in the etiology of male infertility. Eighty-one infertile males and 40 normospermic control subjects were included in this stud. NGF levels were measured in the blood and seminal plasma, and its correlation with total antioxidant capacity (TAC), catalase (CAT) and glutathione (GSH) levels and sperm parameters were studied. There was a general trend of decreased in serum and seminal NGF concentrations of asthenozoospermic and oligoasthenozoospermic when compared to the normozoospermic samples. There was no significant association between NGF and seminal antioxidant status in asthenozoospermia and oligoasthenozoospermia males. Nevertheless, CAT positively correlated with sperm concentration, total sperm motility, and normal sperm morphology but only showed a statistically significant correlation to total sperm motility in asthenozoospermic males. A strong positive association was detected between seminal plasma TAC activity and total sperm motility in both asthenozoospermic and oligoasthenozoospermia males. A decrease NGF levels in serum and seminal plasma could have a significant role in the etiology of impaired sperm functions.

Abstract (sommario):
Introduction. Wuzi Yanzong (WZYZ) formula, a famous traditional Chinese medicinal prescription, has been widely used to treat kidney essence insufficiency-induced oligoasthenozoospermia in ancient and modern clinical practice. Previous studies have demonstrated that WZYZ formula exhibits significantly therapeutic activity. The aim of this study was to evaluate the effect of WZYZ formula on the reproductive hormone levels and the TGF-β1/Smads signal pathway in the testis, to explore the underlying mechanisms of WZYZ formula to improve spermatogenic function of testis in rats with oligoasthenozoospermia. Materials and Methods. In order to control the quality of the drug, the main components of the WZYZ formula were analyzed by HPLC. A rat model of oligoasthenozoospermia was established, by daily administration of tripterygium glucosides for 4 weeks, and treated with 1.62g/kg of WZYZ formula. The testes were histopathologically examined and serum levels of gonadotropin release hormone (GnRH), estradiol (E2), follicle-stimulating hormone (FSH), testosterone (T), and luteinizing hormone (LH) were measured by ELISA. TGf-β1, Smad2, and Smad4 mRNA and protein levels in the testis were evaluated by immunohistochemistry (IHC), quantitative real-time RT-PCR (qRT-PCR), and Western blotting (WB). Result. Oral administration of WZYZ formula restored testicular structure and significantly increased the histology score in the oligoasthenozoospermic rats. In addition, WZYZ also significantly increased the serum levels of GnRH, LH, E2, and T and decreased that of FSH. Meanwhile, TGf-β1, Smad2, and Sma4 expression levels were significantly decreased. Conclusions. WZYZ alleviates oligoasthenozoospermia by restoring the reproductive hormones and targeting the TGf-β1/Smads pathway.

Abstract (sommario):
Oligoasthenozoospermia is a complex disease caused by a variety of factors, and its incidence is increasing yearly worldwide. Yishen Tongluo formula (YSTLF), created by Professor Sun Zixue, has been used to treat oligoasthenozoospermia in clinical practice for several decades with a good therapeutic effect. However, the chemical and pharmacological profiles of YSTLF remain unclear and need to be elucidated. In this study, a network pharmacology approach was applied to explore the potential mechanisms of YSTLF in oligoasthenozoospermia treatment. All of the compounds in YSTLF were retrieved from the corresponding databases, and the bioactive ingredients were screened according to their oral bioavailability (OB) and drug-likeness (DL). The potential proteins of YSTLF were obtained from the traditional Chinese medicine systems pharmacology (TCMSP) database and the Bioinformatics Analysis Tool for Molecular Mechanism of Traditional Chinese Medicine (BATMAN-TCM) database, while the potential genes of oligoasthenozoospermia were obtained from the GeneCards database and the DisGeNET database. The STRING database was used to construct an interaction network according to the common targets identified by the online tool Venny for YSTLF and oligoasthenozoospermia. The topological characteristics of nodes were visualized and analyzed through Cytoscape. Biological functions and significant pathways were determined and analyzed using the Gene Ontology (GO) knowledgebase, the Kyoto Encyclopedia of Genes and Genomes (KEGG) and Metascape. Finally, the disease-formula-compound-target-pathway network was constructed by Cytoscape. A total of 106 bioactive ingredients and 134 potential targets from YSTLF were associated with oligoasthenozoospermia or considered to be therapeutically relevant. Pathway analysis indicated that the PI3K/Akt, MAPK and apoptosis signaling pathways were significant pathways involved in oligoasthenozoospermia. In conclusion, the current study expounded the pharmacological actions and molecular mechanisms of YSTLF in treating oligoasthenozoospermia from a holistic viewpoint. The potential molecular mechanisms were closely related to antioxidative stress, antiapoptosis and anti-inflammation, with TNF, CCND1, ESR1, NFKBIA, NR3C1, MAPK8, and IL6 being possible targets. This network pharmacology prediction may offer a helpful tool to illustrate the molecular mechanisms of the Chinese herbal compound YSTLF in oligoasthenozoospermia treatment.

Abstract (sommario):
Background. Infertility affects approximately 15% of couples around the world, and male factors are accounted for 40–50%. Oligoasthenozoospermia is the most common reason for male infertility. Unfortunately, effective drug therapy is still lacking except for assisted reproductive technology (ART). Previous researchers found that Wuzi Ershen decoction (WZESD) can increase sperm count, enhance sperm vitality, and improve semen quality. However, the pharmacological mechanisms remain unclear. Methods. In this study, we screened compounds and predicted the targets of WZESD based on the TCMSP and BATMAN-TCM database combined with literature searching in the PubMed database. We obtained proteins related to oligoasthenozoospermia through GeneCards and submitted them to STRING to obtain the protein-protein interaction (PPI) network. Potential targets of WZESD were mapped to the network, and the hub targets were screened by topology. We used online platform Metascape and Enrichr for GO and KEGG enrichment analyses. AutoDock Vina was utilized for further verification of the binding mode between compounds and targets. Results. Totally, 276 bioactive compounds were obtained and targeted 681 proteins. 446 oligoasthenozoospermia disease-specific proteins were acquired, and further bioinformatics analysis found that they were mainly involved in the formation of gametes, meiosis, and sperm differentiation. Protein interaction network analysis revealed that target proteins of WZESD were associated with oligoasthenozoospermia disease-specific proteins. The 79 targets of disease-specific proteins, which were anchored by WZESD, mainly participate in the cellular response to the organic cyclic compound, regulation of the apoptotic process, nitricoxide biosynthetic and metabolic process, oxidative stress, and protein phosphorylation regulation, which are the causes for oligoasthenozoospermia. Molecular docking simulation further validated that bioactive compounds originated from WZESD with targeted proteins showed high binding efficiency. Conclusions. This study uncovers the therapeutic mechanisms of WZESD for oligoasthenozoospermia treatment from the perspective of network pharmacology and may provide a valuable reference for further experimental research studies and clinical applications.

Abstract (sommario):
The aim of the study: to analyze the results of the program ІМSI as one of the methods of VRT to ensure in vitro fertilization. Materials and methods. The basis of the study consisted of 100 couples with male factor infertility. Pair was examined and treated at the Institute of reproductive medicine (Kiev) in 2013-2015. The Diagnosis verified, assistance was provided in the framework of standard clinical protocols. The 51 men were diagnosed oligoasthenozoospermia, obstructive and non-obstructive azoospermia - in 28 and 21 men, respectively. Results. There were identified features according to the results of cycles. When native - biochemical pregnancy achieved almost equally often oligoasthenozoospermia and obstructive azoospermia (53.0±6.9% and 53.4±9.4%), whereas non-obstructive in two times less (28.6±9.8%). When critical the difference in results is not traced with obstructive and non-obstructive azoospermia and was 16% lower in cases of oligoasthenozoospermia. Biochemical pregnancies occurred in 63 of the 100 pairs (63.0±4.8%), with oligoasthenozoospermia and 37 of 51 (72.5 per cent), obstructive azoospermia – in 19 of 28 (67.8 per cent), non-obstructive – 7 of 21 (33.3 percent). After reproductive losses (5 of 63, 7.9% as) the end result was lower – 58.0±4.9 per cent. The number of births in total in the group with oligoasthenozoospermia was 35 of 51 (68.6%), obstructive and non-obstructive azoospermia - 17 of 28 (60.7 per cent) and 6 of 21 (28.6 per cent), respectively. Conclusion. The data motivate the need of finding opportunities to improve program performance ІМSI. Promising in this regard is the preparation of the pair to her conduct, which goes beyond the limits of the medical, carried out according to the protocols. An important point should be the identification and leveling of risk factors for general medicine and a social plan. Key words: male infertility, the program ІМSI, results.

Abstract (sommario):
Objective: Overproduction of reactive oxygen species results in oxidative stress, a deleterious process that damages cell structure as well as lipids, proteins, and DNA. Oxidative stress plays a major role in various human diseases, such as oligoasthenozoospermia syndrome. Materials and methods: We evaluated the effectiveness of antioxidant co-supplementation therapy using vitamin C, vitamin E, and coenzyme Q10 in men with oligoasthenozoospermia. Overall, 169 infertile men with oligoasthenozoospermia received antioxidant therapy with 80 mg/day vitamin C, 40 mg/day vitamin E, and 120 mg/day coenzyme Q10. We evaluated spermiogram parameters at baseline and at 3 and 6 months of follow-up. Results: Significant improvements were evident in sperm concentration and motility following coenzyme Q10 therapy. Treatment resulted in 48 (28.4%) partner pregnancies, of which 16 (9.5%) were spontaneous. Significant improvements in sperm cell concentration and sperm motility were observed after 3 and 6 months of treatment. Conclusions: Vitamin C, vitamin E, and coenzyme Q10 supplementation resulted in a significant improvement in certain semen parameters. However, further studies are needed to empirically determine the effect of supplementation on pregnancy rate.

Abstract (sommario):
Objective: To evaluate whether couples with moderate male infertility should be treated with conventional in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI). Patients and Methods: A total of 249 couples with moderate male infertility undergoing their first IVF/ICSI cycle were enrolled in the study. The couples were divided into two groups according to the results of semen analysis: moderate oligozoospermia (O group) and moderate oligoasthenozoospermia (OA group). Sibling oocytes were randomized into groups to be inseminated either by conventional IVF or ICSI. Fertilization rate, embryo quality, implantation rate, and clinical pregnancy rate were examined. Results: There was no difference in the fertilization, implantation, and pregnancy rates between conventional IVF and ICSI in either the O group or OA group (p > 0.05). Additionally, in the OA group, the good quality embryo rate was similar after IVF or ICSI (p > 0.05). However, in the O group, the good quality embryo rate was significantly higher after ICSI than after IVF (p < 0.05). Conclusions: Couples with moderate oligozoospermia or moderate oligoasthenozoospermia did not influence the major indices of IVF. Because of the uncertainties concerning the safety of ICSI, couples with moderate oligozoospermia or moderate oligoasthenozoospermia need not be subjected to this procedure.

Abstract (sommario):
Oligoasthenozoospermia is a crucial factor in male infertility. Wuzi Yanzong (WZYZ) pill is a popular traditional Chinese medicine (TCM) formula which has been used for male infertility treatment for years. However, its effects on semen quality remain controversial. We conducted a preregistered meta-analysis to assess the effect of WZYZ pill for the therapeutic effects on oligoasthenozoospermia. Five randomized controlled trials including 960 participants were selected from databases of domains in North-East Asian regions, PubMed, Embase, and Cochrane Library. WZYZ pill group yielded a greater mean increment on sperm concentration (5 trials: MD 5.99, 95% CI 2.12–9.85, P=0.002), sperm motility (5 trials: MD 4.57, 95% CI 0.47–8.68, P=0.03), sperm morphology (2 trials: MD −1.93, 95% CI −4.87–1.01, P=0.20), activity of acrosomal enzyme (2 trials: MD 28.27, 95% CI 12.41–44.14, P<0.01), volume of semen (2 trials: MD 0.56, 95% CI 0.21–0.91, P=0.002), and a decrement of sperm DNA fragmentation index (2 trials: MD −3.82, 95% CI −6.45–−1.19, P=0.004). However, qualities of selected studies were generally unsatisfactory, and there was inherent heterogeneity among some of the outcomes. Despite these limitations, the WZYZ pill improved sperm quality by improving several semen parameters and decreasing DNA damage in oligoasthenozoospermia patients.
