    Abstract:
    Clinical treatment of recurrent spontaneous abortion (RSA) is still a matter of debate due to the absence of an univocal definition of the term. As a consequence of the reproductive history of the couple, there is still uncertainty regarding the moment when the problem of recurrent abortion arises and this prevents the start of diagnostic evaluation and therapy. In addition to a critical review of the literature, the aim of this study was to evaluate whether two successive abortions with the same partner are sufficient to suggest that the couple should undergo diagnostic test, or if it would be more sensible to wait for other reproductive failures. The study was performed in 50 couples suffering from recurrent abortion who attended the Laboratory of Cytogenetics in the Department of Animal Biology at Turin University for caryotyping in order to exclude the presence of chromosomal aberrations. Interviewed by telephone, out of 50 couples 41 presented the necessary requisites for being included in the study. Follow-up ranged between a maximum of 8.5 years and a minimum of 1 year (mean of 4.7 years). From the data collected it emerged that the probable cause of RSA was identified in 21 out of 41 couples enrolled in the study group (51.2 per cent). In the remaining 20 couples tests were within normal ranges. In all diagnosed cases the reproductive problem was identified with one or more alterations present in women. Among the hypothesized cause of RSA, uterine abnormalities were the most frequent (19.5 per cent), followed by immunological problems (17.1 per cent), etiologic factors of hormonal origin (12.2 per cent), one single case of genital infection (2.4 per cent), one balanced chromosomal translocation (2.4 per cent) and at last only one case of cervical incompetence of (2.4 per cent). The diagnosis was determined effectively in 85.7 per cent of couples. Of 20 couples who had not shown any abnormalities, 80 per cent had had a healthy child without any abortions and with the same partner. In conclusion, diagnostic tests performed finally identified the cause of RSA in 43.9 per cent of the couples who completed the procedure; vice versa, 39.0 per cent of couples solved the problem without the need for diagnostic tests; finally, the remaining 18.1 per cent were unable to carry pregnancy to term. By comparing our results to those reported by other authors, we believe that the probability of identifying the cause of RSA and curing it is sufficiently high to justify the start of the diagnostic evaluation of the problem as early as the second abortion in view of the stress on the couple produced by repeated reproductive failures.
