Academic Meeting of the Mexican Association of Andrology, 2001
On October 25, 2001, an Academic Meeting of the Mexican Andrology Association took place in Monterrey City, Mexico.
The opening conference was conducted by Dr. Héctor Chemes, president of the International Society of Andrology, who reviewed the relationship between sperm pathology and assisted fertilization outcome. It was pointed out that during the last 10 years the practice of ICSI has shown that use of “normal” spermatozoa is not an absolute requirement for fertilization. In those extreme situations, an accurate diagnosis is essential, because in many patients with a severe male factor, a genetic component is present. It is particularly that group of patients with serious spermatic alterations that receives the benefit of proper diagnosis, due to recent experiences demonstrating that some alterations in spermatozoa are responsible for the variable course of fertilization, implantation and progress of pregnancy. Some examples of severe pathologies were presented (flagellar, nuclear, of the sperm neck etc.) with different prognosis after ICSI.
The ethical problems that andrologists face when dealing with patients that require the help of assisted fertilization and that can pass the genetic defect to the next generation was also addressed. Dr. Miguel Diaz, from Guadalajara, Mexico, who was completing his term as president of the Mexican Andrology Association, discussed in detail the genetic alterations that lead to infertility in the male. Rosa Rodriguez, Monica Ruy, Carlos Felix , Raul Mata, and Manuel Garcia in a forum of experts from Mexico, deliberated on the future of assisted reproduction technologies, its pitfalls and the bioethic aspects involved. They also analyzed the lack of legislation in Mexico and other countries, in relation to conservation of frozen human embryos, a big problem that needs the attention of international health organizations.
The current interest in genital infections caused by chlamydia and mycoplasma, as sexually transmitted diseases, was discussed by Guadalupe Gallegos who addressed the limitations that diagnosis and testing procedures represent to understand the real dimension of the problem. Original ultrastructural findings demonstrate a morphological pattern of sperm alterations associated with bacterial penetration: nuclear vacuolization, chromatin decondensation, decrease of the acrosomal area and thickening of flagella. This clinical problem exists largely in patients of the northeast region and the U.S.A.-Mexico border who have a high prevalence of these genitourinary infections. This population was studied by a morphologist group of the University of Nuevo Leon, Mexico led by Dr Guadalupe Gallegos. These investigations indicate a high incidence of chlamydia and mycoplasma genital infections that go undiagnosed until their sequelae lead to infertility. Associated conditions included primary and secondary infertile patients, recurrent abortions, anembryonic and ectopic pregnancies and assisted reproduction failure, particularly during transfer of the embryo. Finally, the possibility of extragenital spread of these infections was stressed in view of the very high frequency of ocular infections coincident with genital involvement.
The program included a workshop with a discussion of technical conditions and clinical interpretation of seminal analysis, including patterns of seminal infection. A video illustrating the techniques of fresh demonstration of genital infections by chlamydia and mycoplasma was presented. The authors (Guadalupe Gallegos, Rosa Rodriguez, Benito Ramos and Monica Ruy, from Monterrey, Mexico), proposed this study as a fast and low cost test, for chlamydial and Mycoplasma detection and its application to high population screening. Octavio Diaz, (Monterrey, Mexico), spoke about technical aspects of embryo freezing as well as legal conditions for seminal bank implementation and the ethics of gametes and embryo donation.
Closing the scientific event the subject of erectile dysfunction was addressed by Dr Rosario Tapia (D.F. Mexico) who reported on the results of simple or combined vasoactive drugs currently in use; Lauro Gomez and Helio Martinez (Monterrey, Mexico) spoke about the results of some surgical procedures and prosthesis installation as treatment of erectile dysfunction. A lively discussion ensued when Dr. Miguel Diaz emphasized the psychological management of the couple as the most effective and innocuous therapeutic approach that can solve a high percentage of cases.
For this academic event the work of Dr. Miguel Diaz as former president of the Mexican Association of Andrology was acknowledged and Dr. Rosario Tapia was named President for the next two years. The Mexican Society of Andrology expressed appreciation to Dr. Hector Chemes with congratulations for his recent election as President of the International Society of Andrology. The meeting was organized and supported by the Medical School of the Universidad Autonoma of Nuevo Leon, Mexico.
