title: [Frequency of altered male factor in an infertility clinic].
abstract: Infertility is the incapacity of a couple to conceive after a year of regular sexual life without using a method for family planning. The infertility state is dependent on the female factor as well as masculine factor; an altered masculine factor is designated when any cause or causes of infertility reside in the male. The masculine factor as a cause of infertility is present in 40 to 50% of cases hence the importance of an integral evaluation of male alterations and its fertility. The World Health Organization (WHO) has proposed to classify the masculine infertility based on semen features.
  
  
  OBJECTIVE
  To determine the frequency of the masculine factor altered in association to diagnosed abnormalities, according to the number of affected seminal indexes based on seminograms performed in infertile patients seen at the department of Human Reproductive Medicine, Hospital Juárez de México.
  
  
  METHODS
  An observational, descriptive, transverse, retrospective study was performed.
  
  
  METHODS
  the seminograms practiced were reviewed from 571 clinical files of couples that the consultation for infertility from January 1993 to February 2001. Collection and analysis of semen samples was based on standards settled by WHO.
  
  
  RESULTS
  Of 571 seminogram informs, 371 (65%) showed alterations in the seminal indexes, the stocking of age of this group was of 31.89 years +/- SD 6.3 years. Our findings were: azoospermia in 89 (23.98%), astenonecrozoospermia in 44 (11.85%), hypospermia in 43 (11.59%), astenozoospermia in 33 (8.89%), oligoastenozoospermia in 31 (8.35%) hyponecrozoospermia in 30 (8.08%), oligozoospermia in 25 (6.73%), others in 21 (5.7%), necrozoospermia in 19 (5.12%), hypoastenozoospermia in 18 (4.85%), cryptozoospermia in 11 (2.97%), and hypooligoastenozoospermia in 7 (1.88%). In 62.6% of seminograms practiced there was an isolated alteration, in 34.4% two alterations and in the remaining 3% more than two alterations.
  
  
  CONCLUSIONS
  We found masculine factor altered in 65% of couples who were requiring consultation for infertility. The three main alterations of seminal indexes were azoospermia, astenonecrozoospermia and hypospermia.
