The 3rd Meeting of the European Association of Genital Microsurgery was held in Lisbon on November 26, 1994 with members and invited guests from 11 European countries. "Microsurgery for male infertility and related assisted reproduction" was the theme chosen for this meeting. The following is a summary of the scientific presentations at the meeting after J. Pereira da Silva, who was responsible for the organization of the meeting, gave his opening remarks.
Dr. L.V. Wagenknecht (Germany) and J.P. Pryor (United Kingdom) dealt with the topic: "Hormones in relation to epididymo-vasal microsurgery." The first speaker defended hypogonadotropic testis excision with epididymo-vasal microsurgery, the latter correlated FSH levels with spermatogenesis.
On "Genetic risks of related assisted reproduction," W. Engel (Germany) concluded, after reviewing the available data, that there is no increased genetic risk.
The third topic of the meeting was "Anatomical and pathological consequences of increased pressure on the seminiferous tubules and spermatogenic tissue over time." F. Hadziselimovic (Switzerland) talked about the long-term effects of vasectomy on the testes based upon a large number of biopsies and concluded that there are typical cellular changes depending on the causes of obstruction and the duration. J.M. Pommerol-Monseny (Spain) and L.V. Wagenknecht (Germany) also discussed this topic. R. Schoysman (Belgium) gave an account of his experience on oocyte fertilization by spermatids in his F.I.V. Unit. G. Colpi (Italy) described the pathological findings in the epididymis using ultrasonography in cases of ejaculatory duct obstruction.
Dr. J.V. Schwarzer (Germany) referred to the experience of his Munich team on TESA and MESA and on microsurgical correction of bilateral varicocele and G. and B. Drawz (Germany) conveyed the surprising results of normozoospermia in 70% of azoospermic patients after successful refertilization.
Dr. L. Gianaroli (Italy) presented a paper on the role of the fertilization current on the activation of the fertilized human oocyte, where he compared that current with experimentally induced currents. The fact that the latter are 2 to 10 fold greater led the author to the hypothesis that spermatozoa only activate a small portion of the primary elements stored in the oocyte. D. Pozza (Italy) presented his MESA results in 26 azoospermic patients. He maintained that different spermatozoa have varying fertilizing capacities according to the epididymis level of sperm retrieval. He concluded that ISIS can overcome some problems encountered with MESA.
The results of epididymovasostomy in patients with severe oligozoospermia of unknown cause were presented by A. Olsson (Sweden). The speaker concluded that the procedure has a real advantage for those patients and for azoospermic men.
Dr. W. Hendry (United Kingdom) discussed the indications for reconstruction versus orchidectomy in subfertile patients with unilateral testis obstruction. From 125 treated patients he analyzed the results attained in 68. He advocated the benefits of reconstruction in post-infection block and the advantages of orchidectomy in congenital and post-surgical obstructions.
The 3rd Meeting was extremely interesting and rich in lively debate. The members of EAGM decided that the Association should continue as a special forum where genital microsurgeons can exchange and share knowledge and experiences in an informal setting.
The next meeting will be held in Barcelona, Spain during November 1995 and will be hosted by J.M. Pomerol-Monseny.
