RESUMO
【Objective】 To investigate the sperm retrieval rate (SRR) of microdissection testicular sperm extraction (M-TESE) in patients with non-obstructive azoospermia (NOA) caused by different causes. 【Methods】 A retrospective analysis was performed on 225 NOA patients during Jan.2020 and Dec.2022. The relation between SRR and patients’ age,body mass index (BMI),testicular volume,endocrine hormones and different etiological classifications were analyzed. 【Results】 According to whether sperm was obtained by surgery,the patients were divided into two groups,including 107 cases in the sperm group and 118 cases in the non-sperm group. There were no significant differences in patients’ age,testicular volume and levels of endocrine hormones between the two groups (P>0.05). According to the different causes,NOA patients with mumps history,cryptorchidism history,AZFc deletion or Klinefelter syndrome (KS) had higher SRR,while idiopathic NOA patients had the lowest SRR (P<0.05). 【Conclusion】 M-TESE is an effective treatment of NOA. There is no correlation between SRR and patients’ age,MBI,testicular volume and levels of endocrine hormones. NOA caused by different etiological classifications may have different SRR.
RESUMO
Objective To investigate clinical effect of kidney essence granule on DNA intergrity in patients with idiopathic weak sperm.Methods 110 cases of idiopathic weak sperm disease in outpatient service of male infertility were selected, and divided into 3 groups using random number table method, treatment group (n=40) treated with strong kidney essence granule and control group (n=40) by Wuzi Yanzong pill treatment, blank control group (n =30) given placebo treatment.Semen parameters and sperm DNA fragmentation index (DFI) differences were compared within groups. Results The efficacy of treatment group was significantly higher than control group and blank control group, and control group was significantly higher than blank control group, the differences were all statistically significant (P<0.05).There was no significant difference among the 3 groups of patients within semen volume, liquefaction time, a,(a+b),(a+b+c) grade sperm percentage, seminal plasma fructose and acid phosphatase level pre-and post-treatment.Pre-treatment, sperm density, sperm abnormality rate, α-glycosides and DFI were not significantly different among the 3 groups.Post-treatment, sperm density in treatment group was significantly higher than that in control group, and sperm deformity rate and DFI were significantly lower than that in control group, and that in control group was significantly lower than that in blank control group (P <0.05) .Pearson correlation analysis showed that the sperm density was negatively correlated with DFI(r=-0.354), and the sperm deformity rate was positively correlated with DFI(r=0.324).Conclusion The main reason for abnormal DNA integrity are renal dysfunction, and kidney essence granule can be used as an effective medicine to improve the integrity of sperm DNA.
RESUMO
Objective To observe the clinical effect of Renzi Shengjing Decoction(Radix Ginseng and Fructus Schisandrae decoction for producing sperms)treating oligospermia and aspermia males with kidney yang deficiency through its influence on semen and hormones.Methods The 60 males with infertility due to oligospermia and aspermia were randomly divided into treated group and control group with 30 cases in each.Before and after treatment,the two groups were tested with the colored semen analysis system for detecting the density,motility and survival rate of sperms respectively.The follicle-stimulating hormone(FSH),luteinizing hormone(LH),testosterone(T),and prolactin(PRL)were measured by enzyme-labeling instrument.Results In the treated group,the improvement of semen parameters and sexual hormones and clinical effect were better than those of control group(P
