The article presents the results of studies of the effect of citrate germanium obtained using nanotechnology and method of chemical synthesis on growth, development and reproductive function of the body of female rats and their offspring viability.

The results of studies suggest watering citrate stimulating effect on the dynamics of germanium body weight and fertility of female rats treated with 20 mg and 200 mg of Ge NGeC. The stimulating effect increased their predetermined multiple pregnancy and milk production, with the increase of number of young rats per group and per one female, their average mass and nestle weight, as well as postnatal growth and survival within two months of life.

It was established that watering of female rats offspring with germanium citrate in amounts of 10 (II), 20 (III), 200 (IV and V) and 2000 g Ge/kg of body weight (VI group) increases the number of newborn rats in II, III, IV and VI groups and their survival at the age of 60 days — only in II, III and IV group compared to the control (I) group. The mass of the heart in females in II, III, IV and VI research groups did not significantly differ from this index in the control group, but the ratio of its mass increased in these groups of animals. In the females of V group the mass of the heart and its weight ratio were lower than their values in control. The absolute mass and weight ratios of the spleen, kidney and liver in females of experimental groups were lower compared to control, but these parameters were less noticeable in animals of II group treated with 10 mg Ge/kg of body weight. The weight ratio of the lungs and weight were the lowest in females of V and VI groups.

It is noted that watering citrate germanium produced by nanotechnology increases dose-dependently multiple pregnancies and milk production in female rats, but finds feedback of dose strength with the number of newborn rats and the offspring survival to 60 days, and also with body weight of rats in sucking period. Higher rates of intensity of growth in young rats by weight of the body in the first 20 days after birth was established in the II (10) and III (20 mg Ge/kg of body weight) groups. Watering germanium citrate to offspring of female rats for two months resulted in a probable increase in liver weight in young rats in II, and heart — in III and VI groups.
