Abstract
This work aimed to evaluate the effects of the aqueous extract of Vepris afzelii roots on a rat model of hypogonadism. Phytochemical screening and acute toxicity of the extract were performed using different procedures. Hypogonadism was induced orally in adult Wistar rats using cyproterone acetate (30 mg/kg) for ten days. Besides six normal rats (10 ml/kg of distilled water, normal control), 30 hypogonadal rats were subdivided into five groups of six animals each, receiving for 14 days: distilled water (10 ml/kg, hypogonadal control), testosterone (4 mg/kg/3days) and the extract of V. afzelii (100, 200 and 400 mg/kg). Sexual behavior, sperm parameters, testes function and structure were assessed. Compared to the normal controls, significant (p = 0.0000) increases in mount (24 ± 0.94 seconds vs. 1200 ± 00 seconds) and intromission (49.16 ± 10.85 seconds vs. 1200 ± 00 seconds) latencies, and post-ejaculatory interval (381.72 ± 37.55 seconds vs. 1200 ± 00 seconds) were observed in all groups receiving cyproterone acetate on day 0. Total inhibitions of mounts (63.50 ± 8.91 vs. 00 ± 00), intromissions (36.66 ± 3.51 vs. 00 ± 00) (p = 0.0000), ejaculations (2.83 ± 00 vs. 00 ± 00, p = 0.0002) frequencies and mean copulatory interval (627.30 ± 81.80 vs. 00 ± 00, p = 0.0000) were also observed in these groups. Moreover, decreases in daily sperm production (2.65 ± 0.19 vs. 1.17 ± 0.08, p = 0.0498), percentage of sperm mobility (78.64 ± 8.41 vs. 10.12 ± 2.32), serum testosterone level (8.39 ± 0.63 ng/dl vs. 1.68 ± 0.19 ng/dl), diameter of seminiferous tubules (111.97 ± 0.51 µm vs. 94.51 ± 0.57 µm) and height of germinal epithelium (46.58 ± 0.34 µm vs. 33.74 ± 0.66 µm) (p = 0.0000) associated with increases in sperm transit (3.13 ± 0.45 vs. 11.07 ± 1.45, p = 0.0000) were also observed in these groups. Interestingly, compared to hypogonadal control and day 0, the administration of V. afzelii extract induced significant (p = 0.0000) improvements in all these altered parameters with 400 mg/kg being the most active dose. These results, attributed to saponins, flavonoids, polyphenols and triterpenes detected in this plant's extract confirm its traditional usage and could be useful for the management of patients suffering from hypogonadism.

Saikia Q, Hazarika A, Kalita JC. Isoliquiritigenin ameliorates paroxetine-induced sexual dysfunction in male albino mice. Reprod Toxicol 2023; 117:108341. [PMID: 36740106 DOI: 10.1016/j.reprotox.2023.108341] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2022] [Revised: 01/28/2023] [Accepted: 02/01/2023] [Indexed: 02/05/2023]
Abstract
Paroxetine (PRX), a widely prescribed antidepressant, often leads to sexual dysfunction. The available management options such as sildenafil (SDF), are associated with side effects. The present study investigates the fertility-boosting properties of isoliquiritigenin (ISL) on PRX-induced sexual dysfunction in male mice. We allocated fertile mice into six different groups (n = 5): group I- DMSO; group II- PRX; group III- co-administered PRX and SDF; group IV- ISL alone; group V- co-administered PRX and ISL (low dose); and, group VI- co-administered PRX and ISL (high dose). 14 days post treatment, animals were sacrificed, and the weights of the testis and epididymis were evaluated. Furthermore, sperm parameters, testicular and epididymal antioxidant levels, serum testosterone and nitric oxide (NO) levels, histoarchitecture of testis and epididymis, and markers of cellular toxicity were assessed. Results revealed that the PRX administration reduced organ weights, sperm count, intact acrosome, catalase (CAT), superoxide dismutase (SOD), glutathione (GSH), serum testosterone, and NO levels, and increased sperm abnormalities and MDA levels (a biomarker for lipid peroxidation). Additionally, we observed damage in the testis and epididymis. The toxicity biomarker study revealed a higher concentration of SGOT, SGPT, and ALP enzymes in the PRX-treated group. However, the co-administration of PRX with ISL ameliorated the adverse effect of PRX on the parameters mentioned above. The PRX+ISL (high) results were almost at par with the PRX+SDF group. The group that received ISL alone showed overall improvements. In conclusion, our comprehensive panel of tests indicates that ISL could be helpful in managing sexual dysfunction.

Construction and internal validation of a prediction nomogram for acquired premature ejaculation (APE) in PE patients. Andrology 2020; 9:886-893. [PMID: 33289965 PMCID: PMC8247358 DOI: 10.1111/andr.12956] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2020] [Revised: 11/18/2020] [Accepted: 12/03/2020] [Indexed: 01/23/2023]
Abstract
Background A predictive model for acquired premature ejaculation (APE) in PE patients has not yet been established. Objectives This study was aimed at determining which factors were independently associated with the possibility of predicting APE in PE patients, and whether an effective pre‐treatment nomogram for predicting their individual chances of being APE in PE patients can be developed. Materials and methods We analyzed the medical histories of 915 PE patients diagnosed at Xijing Hospital (Xi'an, China) and Northwest Women's and Children's Hospital (Xi'an, China) between May 2019 and May 2020. The diagnostic nomogram was developed using a multivariate logistic regression model by integrating selected significant variables determined through univariate analysis. Receiver operating characteristic curves were used to measure the predictive accuracy of the nomogram and its constituted variables, and calibrations were performed by making a comparison of nomogram‐predicted probability with actual rate of APE. Results The independent predictors for APE that were identified include Age, Intra‐vaginal Ejaculation Latency Time (IELT), Frequency of sexual desire (FSD), and Eysenck Personality Questionnaire‐Revised Short Scale for Chinese (psychoticism) [EPQ‐RSC(P)] scores. The predictive accuracy of the nomogram was 0.782 (95% CI: 0.723–0.841). Also, excellent agreement was demonstrated between the nomogram‐predicted probability and the actual rate of APE. Discussion and conclusion We identified 4 independent predictors for APE and demonstrated the potential significant differences in psychoticism between LPE and APE patients. This was the first internally validated predictive APE nomogram where good discrimination and calibration were applied, and it offers a promising role in clinical practice. More studies are necessary for verification of its universal applicability.
