Relationship between risk factors for male infertility and spermogram alterations

Abstract

Background: multiple risk factors can increase male infertility. Objective: to relate risk factors for male infertility with alterations in the spermogram, in infertile men treated at the Assisted Reproduction Center of the "Ana Betancourt de Mora" Provincial Gyneco-obstetric Teaching Hospital of Camagüey, during the year 2020. Methods: an analytical study was carried out at the aforementioned institution and during the period herein declared. By simple random sampling, 150 infertile men were selected. The inferential method was used to relate each risk factor with alterations in the spermogram; The contingency coefficient C was used to measure the degree of association, with a reliability of 95 % and significant correlations when the values were greater than 0,7. Results: oligospermia was the most frequent disorder (77,33 %), followed by asthenospermia (70,66 %) and teratospermia (52,66 %). 56 % of the men were between 40 and 59 years of age, 63,3 % with more than 40 years. Of the environmental risk factors, exposure to pesticides (20 %), heavy metals (17,33 %) and excess heat (14,66 %) were the ones with the highest incidence. Varicocele (48,66 %) and genitourinary tract infections (42 %) were the most frequent conditions. Pesticides and varicocele were the risk factors with a significant correlation mostly showed by the spermogram results. Conclusions: there were risk factors with a significant association with alterations in the spermogram, which could have a negative influence on reproductive health.
