We studied the distribution of GSTM1 phenotypes in 611 individuals from an ethnically mixed sample of the Brazilian population who died from various causes. No influence of age, gender, or ethnicity was detected on the phenotypic distribution. In a sub-sample of 66 alcoholic individuals compared with 399 non-alcoholics there was almost a doubling of the odds ratio for GSTM1(0) individuals in the alcoholic category. The incidence of hepatopathies was higher in this group as well, and we observed a significant association of the null phenotype with cirrhosis. An excess of null phenotypes (374/611) was observed, and the allelic distribution was: GSTM1*A = 0.168, *B = 0.089, and *0 (null) = 0.743.
OBJECTIVE: To analyse the factors predisposing to male immunological infertility from the hospital records of 508 patients that had been treated for infertility in the Turku University Central Hospital from 1980 to 2000. In addition, the hormonal status was investigated at the beginning of treatment. RESULTS: Patients with a history of mumps, or either a fresh varicocele or a history of varicocele had statistically significant lower levels of MAR antisperm antibodies (ASAs) than patients with no such conditions. Repair of varicocele (either surgical or embolisation), showed a statistically significant enhancement of the total sperm cell counts in ejaculates, but it appeared not to have any influence on other parameters of the semen analysis (mobility and morphology). Of all male infertility patients, 66.3% had normal hormonal status at the beginning of treatment, 12.6% of patients had hypotestosteronemia and 22.1% had subclinical hypogonadism. Patients with subclinical hypogonadism had lower total sperm cell count in ejaculates than patients with normal hormonal status although they had statistically significant more offspring. In addition, it appeared that mumps orchitis as well as smoking and alcohol abuse are risk factors for subclinical hypogonadism. CONCLUSION: No clear predisposing factor for male immunological infertility could be found. However, patients with subclinical hypogonadism differed from other male infertility patients and thus may form a special group among the male infertility patients.
