    Abstract:
    An epidemiological study of the occurrence of different Mycoplasmas in seminal fluid and in cervical secretions from patients with reproductive failure and in 2 control groups is described. All patients underwent a series of fertility tests before inclusion in the study and those with abnormal findings were excluded. Group A consisted of 36 couples in whom no cause of infertility could be found and group B of 19 couples in whom serum antibodies agglutinating donor sperm in different titers were detected in the women but not in the men. 2 control groups consisted of 40 women in group C attending a prenatal clinic and 23 men in group D married to women in the 3rd-9th month of pregnancy. Among the subjects, sperm specimens were obtained from the men and cervical swabs from the women on the 2nd or 3rd day of the menstrual period and cultured for Mycoplasmas. Cervical swabs taken after postcoital tests, and cervical and sperm specimens taken during the luteal phase were also cultured. Cervical and sperm specimens from the controls were also cultured. In group A, large colony-forming Mycoplamas were found in cervical secretions of 7 women and in seminal fluid of 2 men. T-Mycoplasmas were found in both spouses in 28 couples and in 3 women and 2 men with negative partners. In group B, large colony-forming Mycoplasmas were found in 2 women and 1 man whose partners were negative. T-Mycoplasmas were isolated from both spouses in 17 of the 19 couples and from the wife only in 2 couples. In group C, classical Mycoplasmas were found in 3 and T-Mycoplasmas in 9 of the 40 cases. In group D, no classical Mycoplasmas were discovered but T-Mycoplasmas were found in 6 of the 23 cases. The observed difference in frequency of T-Mycoplasmas between patient and control groups was highly significant statistically. T-Mycoplasmas were found growing from the spermatozoa but not from the supernate in 7 of 10 specimens obtained from men in group B. In 2 of the remaining 3 specimens, T-Mycoplasmas were found both in spermatozoa and in the supernate, while in the last specimen, no growth was found.
