Methods： We treated a series of 35 cases of SAI with electroacupuncture combined with herb cake-partitioned moxibustion, observing the variation before and after treatment in symptom integral, sperm status, sex hormone and prostate function. Results： After treatment, the patients were remarkably improved in symptom integral, sperm status, sex hormone and prostate function as compared with those prior to treatment. Conclusion： Acupuncture-moxibustion is an effective therapy for SAI.展开更多

Methods： A total of 118 patients received acupuncture-moxibustion treatment. Before and 3, and 6 months after the treatment were detected their seminal plasma acid phosphatase, sperm concentration, sperm viability and sperm motility were measured. Results： The differences between before and after treatments in sperm motility and seminal plasma acid phosphatase levels were statistically significant （P〈0.01）. Conclusion： Acupuncture-moxibustion can improve seminal plasma acid phosphatase levels in infertility patients.展开更多

Methods: Forty-four infertile males with idiopathic oligo-asthenozoospermia were randomly allocated to the treated (n=24) and non-treated (control, n=20) groups. Semen analysis was carried out by light and transmission electron microscopy (TEM) before and 12 weeks after FSH therapy. ICSI was performed in all couples. Results: TEM revealed a significant improvement in sperm quality after FSH treatment, particularly in men with their partners achieving clinical pregnancy. The preg nancy rate was 33 % in the treated group and 20 % in the control. Conclusion: Results highlight a positive role of FSH therapy in infertile males before ICSI, which was correlated vvith an increased pregnancy rate in treated couples. We believe that improved sperm ultrastructure after FSH therapy could positively influence the quality and early stage of embryo development, thereby increasing the probability of embryo implantation.展开更多
