[Peculiarities of sexual behavior of female rats with hyperandrogenia in pubertal and postpubertal periods].

The parameters of female and male sexual behavior in 3- and 6- month old female rats which were exposed to an androgen excess (subcutaneous implantation of Silastic capsules containing 5 mg of crystalline testosterone) from the beginning of pubertal period (at the age of 35 days), or within postpubertal period (at the age of 4 months). Hyperandrogenia in pubertal period had no effect on female sexual behavior formation, but it led to appearance of male behavior components in 100% of animals. In female rats which were implanted with testosterone capsules in postpubertal period, sexual disturbances were more pronounced and were characterized by masculinization and defeminization, which was due to a higher degree of androgenic saturation. The data obtained suggest a leading role of hyperandrogenemia in the pathogenesis of sexual behavior disturbances in female rats in different periods of individual development.
