Complementary and Alternative Medicine Usage and Its Determinant Factors Among Infertile Men in Iran

The Ameliorative Impact of Cichorium intybus L. Distillate on Reproductive Parameters in Male Mice

Background

Cichorium intybus L. (Kasni) distillate is widely used in Eastern countries as a safe herbal drink to improve male fertility. However, the potential effects on fertility parameters and possible adverse effects have not been studied experimentally. The current study aims to evaluate the impact of Cichorium intybus L. distillate (CD) on male mice fertility.

Methods

In the present study (Shiraz, Iran), 30 male mice (30-35 g) were divided into three groups. 10 mice received distilled water (DW) for five weeks as the control group. Another 10 mice, named group CD1/2, received chicory distillate of 1/2 dilution, and the other 10 mice received chicory distillate of CD1/4 dilution as CD1/4 group, ad libitum for three weeks, and they received DW for two weeks afterward. Experimental mice were sacrificed on day 35, and sperm analysis and sera collection were performed for further investigation of FSH, LH, testosterone, and some liver and kidney function parameters. We used the left testis for stereological analysis, and the right one was excised to investigate the expression of the androgen receptor gene. For statistical analysis using SPSS 18.0, mean±SD values were analyzed by one-way analysis of variance (ANOVA) with Dunnett's analysis as post hoc to compare between groups. In stereological investigations, the Kruskal-Wallis method was used for pairwise comparisons to compare groups. The P value was considered statistically significant at P<0.05.

Results

Treatment with CD1/2 resulted in the elevation of serum FSH (P=0.002), LH (P=0.009), testosterone (P=0.034), seminiferous tubule epithelium volume (P=0.029) and length (P=0.028), and Leydig cells number (P=0.009) in comparison with the control group. Administrating CD1/2 (P=0.038) and CD1/4 (P=0.013) significantly increased sperm count compared to the control group.

Conclusion

The results revealed that using chicory distillate can improve hormone levels and sperm count in male mice.

Maca (Lepidium meyenii Walp.) on semen quality parameters: A systematic review and meta-analysis

Background: This study aimed to examine the evidence for the effect of Lepidium meyenii Walp. [Brassicaceae] (L. meyenii W.), known as maca, on improving semen quality.

Methods: Nine databases were searched for randomized controlled trials (RCTs) that examined the parameters for improvements in semen quality, regardless of the type of L. meyenii W. The risk of bias (ROB) among the studies was evaluated according to the Cochrane ROB tool.

Results: Five RCTs met all of the inclusion criteria. Three RCTs showed mixed efficacy of maca in improving semen quality parameters, including sperm concentration and sperm motility, in men experiencing infertility. The meta-analysis also failed to show the efficacy of maca in increasing the sperm concentration compared to the placebo (weighted mean difference, 2.22, 95% confidence interval −2.94 to 7.37, p = 0.4). Two other RCTs also showed mixed effects of maca on several semen quality parameters in healthy men.

Conclusion: The evidence from the included studies suggests unclear effects of maca on semen quality parameters in both men experiencing infertility and healthy men. However, the total number of RCTs and the total sample size were too small to draw firm conclusions.

Iranian nurses' knowledge and attitude toward complementary and alternative medicines: Is there any relation with quality of nursing care?

Background

Nurses play an important role in advising and guiding patients on effective treatments, and in this situation, it is better to be aware of complementary and alternative medicine (CAM) as well as the effects and side effects of different procedures. In addition, the quality of nursing care is directly related to the nurse's knowledge of the different treatments and preventions of different diseases and conditions. The present study aimed to investigate Iranian nurses' knowledge and attitude toward complementary and alternative medicines (CAMs) as well as their correlation with the quality of patient care.

Materials and methods

This cross-sectional study included 267 clinical nurses from three hospitals in southern Iran. The participants were recruited using convenience sampling methods in 2020-2021. A demographic questionnaire, knowledge and attitude toward CAM questionnaires, and the Quality Patient Care Scale were used to collect data.

Results

The mean score of CAM knowledge was 26.51, which was less than the questionnaire midpoint of 39. The mean score of attitudes toward CAM was 63.84, which was more than the questionnaire midpoint of 57. The mean score of the quality of patient care was 197.80, which was more than the questionnaire midpoint of 130. There was no significant correlation between knowledge about CAM, quality of patient care, and its dimensions. In addition, there was no significant correlation between attitudes toward CAM, quality of patient care, and its dimensions (P > 0.05).

Conclusion

The results of the present study showed that nurses' attitudes toward the use of CAM are positive and can be a sign of their readiness to use and further integrate clinically approved CAM in patient nursing care. Due to the role of nurses in patient care and treatment, there is a need to increase nurses' knowledge of CAM, and its training should be included in the nursing curriculum. More studies are needed to identify nurses' knowledge and attitudes toward CAM and its impact on the quality of nursing care.
