Serum luteinizing hormone follicle-stimulating hormone and prolactin in neonatal-androgenized rats.
Serum levels of LH, FSH, Prolactin and Testosterone of 90 days old male rats androgenized soon after birth were determined by specific radioimmunoassay and were compared to untreated rats. LH and FSH levels were also determined in 90 days old female rats neo-natally treated with testosterone and compared with normal diestrus rats. Androgenization of male rats significantly increased serum FSH and Prolactin levels without producing changes in plasma LH and testosterone concentrations. Similar increase in the FSH levels were found in androgenized female rats although plasma FSH concentrations were lower than in the male groups. These results obtained in male rats give an additional evidence that androgens acting in the first days of life are responsible of the higher levels of FSH and Prolactin that characterize the male or tonic pattern of gonadotrophin secretion.
