The aim of the study – to establish the link between the functioning of pineal gland, reproductive system and pregnancy.
Materials and Methods. The research was conducted on 20 adult non-linear female nulliparous white rats Rattus Norvegicus Wistar (study group). Control group included 16 female rats with the same parameters. After occurrence of pregnancy the rats were exposed to light 24 hours/day by halogen lights of “white” light, meanwhile the rats of control group had a regimen “12 hours of light/12 hours of darkness”. After 21 days of confirmed pregnancy the rats were slayed. The uteruses of the rats underwent pathohistological examination.
Results and Discussion. The discontinuation of the pregnancy development was found in all rats of study group, whereas in control group pregnancies developed normally. Pathohistological examination confirmed the changes of endometrium typical for pregnancy.
Conclusion. The depression of function of pineal gland, caused by enlightenment, has a direct impact on pregnancy process and can be a reason of pregnancy termination.
