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.

[Hydrophilic and lipophilic nutrients for the treatment of male idiopathic infertility: a randomized, comparative, open-label, multicenter, prospective, controlled study].

Introduction: the efficiency of nutrient therapy for idiopathic male infertility remains controversial. In particular, it is not unclear if hydrophilic or lipophilic nutrients are more effective.

Aim: to compare the efficiency of a complex containing hydrophilic components (L-carnitine, zinc, selenium, vit.

[Hormonal feature of the androgen status in different-aged males.].

The examined males (n=374) aged from 20 to 69 years were divided into five age groups: the 1st - 20-29 years; the 2nd - 30-39 years; the 3rd - 40-49 years; the 4th - 50-59 years; the 5th - 60-69 years. There was 16,1±7 nmol/l total testosterone level in serum of all aged group. Hormonal signs of androgen deficiency, increased elderly aged groups, were revealed in males of the 2nd group as compared with males of the 1st group.

[The use of nutrient complexes in idiopathic male infertility associated with asteno- and/or teratozoospermia: the search of predictors of treatment efficiency (preliminary results)].
