Long-term effects of perinatal androgenization on reproductive parameters of male rat offspring androgenization and male rat reproduction
It is known that during sex differentiation, fetal androgens are critical determinants of the male phenotype. Although testosterone is necessary for normal development of male sexual behavior, perinatal androgen treatment can result in disruption of normal male sexual reproduction. Pregnant Wistar r...
