A common method of handling missing values. A meta-analysis was used to combine these results. Results. Subjects who received 8-12 mg/day buprenorphine had 1.26 times the relative risk of discontinuing treatment (95% confidence interval 1.01-1.57) and 8.3% more positive urinalyses (95% confidence interval 2.7-14%) than subjects receiving 50-80 mg/day methadone. Buprenophrine was more effective than 20-35 mg/day methadone. There was substantial variation in outcomes in the different trials. Conclusions. The variation between trials may be due to differences in dose levels, patient exclusion criteria and provision of psychosocial treatment. The difference in the effectiveness of buprenorphine and methadone may be statistically significant, but the differences are small compared to the wide variance in outcomes achieved in different methadone treatment programs. Further research is needed to determine if buprenorphine treatment is more effective than methadone in particular settings or in particular subgroups of patients. Theodore J CiceroRoy D. BellW G WiestEli RobinsThe function of the secondary sex organs was found to be markedly impaired in 29 participants in a methadone maintenance program. The ejaculate volume and seminal vesicular and prostatic secretions were reduced by over 50 per cent in methadone clients, as compared to 16 heroin addicts and 43 narcotic-free controls. Serum testosterone levels were also approximately 43 per cent lower in methadone clients than in controls or heroin users. Although the sperm count of methadone clients was more than twice the control levels, reflecting a lack of sperm dilution by secondary-sex-organ secretions, the sperm motility of these subjects was markedly lower than normal. On all measures of secondary-sex-organ and testicular function, heroin addicts appeared to fall between the methadone and control subjects, but, with the exception of sperm motility, the deviation from control values did not reach statisitcal significance.Jack H. Mendelson John MendelsonV D PatchHeroin use was consistently associated with low plasma testosterone levels in narcotic addicts. Heroin addicts maintained on high dosage methadone (80-150 mg/day) also had depressed testosterone levels. Patients on low dosage methadone maintenance (10-60 mg/day) had testosterone levels which were not significant;y different from normal adult male controls. An inverse relationship between methadone dosage and plasma testosterone occurred during methadone detoxification. These findings indicate that heroin and methadone alter male androgen levels with possible derivative effects upon sexual and aggressive behaviors.William D. Spring Mark WillenbringThomas L. MadduxWe administered the Derogatis Sexual Functioning Inventory to 25 methadone maintenance patients who had been on a stable dose of methadone for at least 2 months, and obtained ratings of depression and anxiety, levels of sex hormones, and liver function tests. Five subjects with significantly lower Global Sexual Satisfaction Index scores (p P. Jr. CushmanM J KreekPlasma testosterone values in 8 selected stable male methadone patients were studied before and after their daily methadone dose. Their plasma methadone concentrations rose after methadone, but there were no significant changes in their plasma testosterone, prolactin, follicle stimulating hormone or luteinizing hormone levels. Although patients' plasma containing higher levels of methadone tended to have lower testosterone level, no simple relationship was found. Daily
