从术后时间及环孢霉素A剂量探讨男性肾移植患者的授孕时机

目的:探讨男性肾移植患者术后授孕比较适合的时机。方法:将26例肾移植术后不同时期以及应用环孢霉素A(CsA)不同剂量的患者分为3组:A组7例,肾移植术后<6个月,CsA剂量为4.1～6mg/(kg.d);B组11例,肾移植术后6个月～2年,CsA剂量为2.1～4mg/(kg.d);C组8例,肾移植术后>2年,CsA剂量为1.3～2mg/(kg.d);对上述患者的精液进行检测,并与12例正常男性的精液进行比较。结果:术后不同时期以及CsA不同剂量患者的精液pH值、精液体积、精子存活率和精子密度方面,各组间差异无显著性(P>0.05);但是在精子活动力、精子头部缺陷方面,肾移植术后<6个月与2年后比较,差异有显著性(P<0.05)。结论:男性肾移植患者选择手术2年后授孕是比较适合的时机。

Impregnate Occasion for Male Renal Transplant Recipients

OBJECTIVE: To explore the impregnate occasion for male renal transplant recipients. METHODS: Twenty-six male renal transplant recipients were divided into 3 groups according to the post-transplantation time and the administered dose of Cyclosporine A: 7 in Group A (less than 6 months after renal transplantation and at the dose of 4.1-6 mg/kg x d]), 11 in Group B (6-24 months and 2.1-4 mg/kg x d]) and 8 in Group C (longer than 24 months and 1.3-2 mg/kg x d]). The semen of the patients were detected and compared with those of 12 normal volunteers. RESULTS: Statistically significant differences were observed in sperm motility and sperm head deformity between Group A and C (P < 0.05), but not in pH value and sperm volume, vitality and concentration among the 3 groups (P > 0.05). CONCLUSION: For male renal transplant recipients, 2 years or longer after the transplantation is the most suitable time for impregnation.
