Adult female rats receiving long-term estrogen treatment displayed the species-typical motor pattern of ejaculation during copulation. This hormone treatment produced pituitary hypertrophy and concomitant pressure damage to brain areas dorsal to the pituitary, but did not cause clitoral hypertrophy. The demonstration of the ejaculatory pattern in perinatally untreated female rats indicates that the potential for the expression of the ejaculatory or "orgasmic" pattern is not dependent on exogenous androgen at any stage of development and is more widely represented among female mammals than previously believed.
接受长期雌激素治疗的成年雌性大鼠在交配过程中表现出典型的射精运动模式。这种激素治疗导致垂体肥大，并伴随对垂体背侧脑区的压力损伤，但未引起阴蒂肥大。在出生后未接受治疗的雌性大鼠中证明射精模式表明，射精或“性高潮”模式表达的潜力在发育的任何阶段都不依赖于外源性雄激素，并且在雌性哺乳动物中的表现比以前认为的更为广泛。
