[Personal experience with salpingoplasty. Apropos of 285 cases].

285 cases of salpingoplasty are reported and studied. Only 172 patients could be followed up recently. The percentage of pregnancies was 27-7, 20 per cent were intra-uterine pregnancies. The percentage of successful pregnancies was 45-93 if only those patients who were seen again were reviewed. The results are best when the operation is carried out in the most conservative and most anatomically restorative fashion. This fine surgery, which must be carried out so delicately and with such detail, which will appeal more and more to modern technicians using micro-surgery, should stay in the hands of specialists because there is no doubt that the level of success rises with the experience of the operator.

[45,X/ 46,XX/ 46,XY Mosaic with female phenotype].

Report on a girl with female phenotype and 45,X/46,XX/46,XY mosaicism. The patient showed primary amenorrhea, low stature (1,47 m), but no other typical features of Turner's syndrome. Chromosome studies were carried out on cultures of blood lymphocytes, with usual methods and with R- G- and Q-banding: 43,3 % of cells were 46,XY ; 36,6 % were 45,X and 20 % were 46,XX. The chromosome Y is a non-fluorescent one. A comparison is made with other published cases.

[Attempt at a standardized interpretation of testicular histopathology in male sterility].

The authors present a standard for interpreting the histopathology of testicular biopsies carried out during the framework of investigation of male sterility. The standard is based on a study of the alterations in the seminiferous tubes (T), the peritubular membranes (M) and the interstitial tissue (I). This method of histological assessment has been used to study 35 subjects on whom bilateral bipolar biopsies were carried out (130 specimens). The statistical study showed: a) the absence of any difference between the pieces taken from the two poles in each testis; b) the level of concentration of spermatozoa could not be tied up with any of the three histological parameters. This applied also for hormone levels with the exception of GUT which seem to correlate directly with M; c) the presence of a varicocoele does not reflect in any way the membrane or the interstitial tissue; d) spermograms carried out after the biopsies showed that testicular biopsy does not cause permanent trauma to the testis. The advantages and disadvantages of this quantitative method are discussed.
