RESUMO
ObjectiveTo observe the clinical efficacy of herb-partitioned moxibustion on the navel combined with Yishen Tongluo prescription in the treatment of infertility induced by idiopathic asthenozoospermia （iAZS） with kidney-Yang deficiency and collateral obstruction syndrome and its effect on sperm DNA damage and superoxide dismutase （SOD） in the seminal plasma. MethodsA total of 112 eligible patients who met the inclusion criteria were randomly divided into an observation group （56 cases） and a control group （56 cases）. The patients in the observation group were treated with herb-partitioned moxibustion on the navel combined with Yishen Tongluo prescription，while those in the control group received levocarnitine oral liquid. The primary observation indicators included spouse pregnancy rate，progressive motility （PR），and total sperm motility，and the secondary observation indicators included sperm DNA fragmentation index （DFI），SOD in the seminal plasma， and improvement of TCM syndromes. The treatment cycle was 12 weeks. Before and after treatment，the PR，total sperm motility，sperm DFI，SOD in the seminal plasma， and TCM syndrome scores were recorded. The patients were followed up for 12 weeks and the pregnancy status of spouses within 24 weeks （half a year） was recorded. The clinical efficacy of the two groups was evaluated. ResultThe pregnancy rate of spouses in the observation group was 15.69% （8/51）， higher than 3.85% （2/52） in the control group （χ2=4.118，P<0.05）. The total effective rate of the observation group was 88.24%（45/51）， superior to 69.23% （36/52）in the control group （Z=-3.402，P<0.01）. After treatment， PR， total sperm motility，sperm DFI， SOD in the seminal plasma， and TCM syndromes of the two groups were improved compared with those before treatment （P<0.05）， and the observation group was superior to the control group （P<0.05）. ConclusionHerb-partitioned moxibustion on the navel combined with Yishen Tongluo prescription in the treatment of iAZS-induced infertility patients with kidney-Yang deficiency and collateral obstruction syndrome can increase PR，total sperm motility， and SOD level in the seminal plasma， reduce sperm DFI，improve the TCM symptoms of patients， and improve the pregnancy rate of spouses. The mechanism may be attributed to the fact that this treatment can increase the SOD level in the seminal plasma of patients，enhance the body's antioxidant function，protect sperm from oxidative stress damage，and reduce sperm DFI.
RESUMO
OBJECTIVE@#To evaluate the clinical effectiveness and safety of the Chinese medicine (CM) Qixiong Zhongzi Decoction (, QZD) in the treatment of patients with idiopathic asthenozoospermia.@*METHODS@#A total number of 66 patients with idiopathic asthenozoospermia were included and randomly divided into treatment and control groups by SAS-generated code from January 2015 to August 2016, 33 patients in each group. Patients in the treatment group were administered with 150 mL of QZD twice a day, whereas those in the control group were given 1 g of levocarnitine oral liquid twice a day. The two groups received the indicated medication for 12 weeks and were then followed up for 4 weeks. The primary outcome was sperm motility, and the secondary therapeutic indices were sperm volume, density, pregnancy probability, and CM syndrome score. The comparison between groups was carried out at 4, 8 and 12 weeks, respectively. The safety was determined before and after treatment.@*RESULTS@#(1) Drop-off: 5 cases (7.58%) were lost after treatment (2 from the treatment group and 3 from the control group). (2) Primary outcomes: after 8- and 12-week treatment, the progressive sperms in the two groups were significantly higher than the baseline (all P0.05), however, the CM syndrome score of the treatment group significantly declined compared with baseline level at each time points (all P<0.05). (4) Safety: no obvious side reactions were found during the treatment in both groups.@*CONCLUSION@#QZD could improve the progressive and non-progressive grade sperm in the treatment of idiopathic asthenozoospermia. It is safe with no obvious side effects.
RESUMO
Objective@#To investigate the expressions of solute carrier family 22 member 14 (SLC22A14) and sperm-associated antigen 6 (SPAG6) in the sperm of idiopathic asthenospermia men.@*METHODS@#We collected semen samples from 50 idiopathic asthenozoospermia patients and another 50 normal sperm donors, purified the sperm by discontinuous density centrifugation on Percoll gradients, and then determined the mRNA and protein expressions of SLC22A14 and SPAG6 by RT-PCR and Western blot, respectively.@*RESULTS@#Compared with the normal controls, the idiopathic asthenozoospermia patients showed significantly decreased mRNA expressions of SLC22A14 (0.77 ± 0.08 vs 0.53 ± 0.10, P<0.01) and SPAG6 (0.78 ± 0.09 vs0.52 ± 0.10 , P<0.01) and protein expressions of SLC22A14 (0.80 ± 0.09 vs 0.55 ± 0.10 , P<0.01) and SPAG6 (0.78 ± 0.09 vs 0.56 ± 0.09, P<0.01).@*CONCLUSIONS@#T The expressions of SLC22A14 and SPAG6 are reduced in the sperm of the patients with idiopathic asthenospermia, which may be one of the important causes of asthenospermia.
