Stress and fitoestrogenization in the neonatal period as factors of hypofertility in male rats

Abstract

Aim. In order to identify the effects of emotional stress  and/or phytoestrogen excess intake of during milk feeding for course of programming processes, maturation  and functioning of reproductive function of adult males their ability to reproduction have been investigated. Results. It was revealed that the effect of emotional stress  in this critical period leads to a decrease of copulatory activity and fertility (more than by 40%) in adult males. Consumption of phytoestrogens against the background  of stress at between feeding period enhances these consequences, resulting in an increase of the part of males who were unable to mating and to be the fathers of viable  offspring. Conclusions. Emotional stress and excess intake of phytoestrogens during milk feeding may be the factors for disprogramming hypofertility of adult males.
