ABSTRACT
According to the Russian Society of Urologists, the frequency of infertility in marriage in the Russian Federation is 8-17,2%; half of the cases are associated with the male factor. Among the risk factors for the development of male infertility, there are mainly medical reasons, lifestyle factors and negative environmental factors. Despite the fact that the problem of infertility is addressed by men of different ages, from youth to the elderly, the correction of risk factors is usually carried out without taking into account the age of the patient, which makes it difficult to develop a personalized strategy for the treatment or prevention of infertility. The aim of the study was to study the structure of the leading risk factors for the development of infertility in men from infertile couples, to identify and characterize their age-associated features. The analysis of the medical histories of 1 198 men from infertile couples and the collection of information on all available risk factors for infertility were carried out. The analysis of age features was performed by dividing the sample into 5 age groups: 1st (n=271) – men ≤29,9 years; 2nd (n=415) – 30-34,9 years; 3rd (n=291) – 35-39,9 years; 4th (n=141) – 40-44,9 years; 5th (n=80) – ≥45 years. It was shown that in the general sample of medical causes, factors associated with chronic inflammation predominate: sexually transmitted infections (STIs) – 54%; prostatitis – 32%; obesity – 27%; from non-medical: alcohol – 73%; stress – 47%; smoking – 41%. With increasing age, the frequency of obesity, STIs, prostatitis, hepatitis B/C, mumps increases statistically significantly, while the most unfavorable group of men is 40-45 years old for factors such as STIs, hepatitis B/C and mumps, and the group of men over 45 years old for factors such as obesity and prostatitis.
