男子乳房发育症(Gynecomastia)占男性乳房疾病的65％以上,临床所见大多属生理性,见于发育期男孩、新生儿和男子更年期,尤以发育期男孩多见,发生率可达60％以上。据报告,发病高峰为14岁,平均持续1～2年。生理性男子乳房发育症是由一过性雌、雄激素比例失调所致,此外,与生长激素、肾上腺皮质激素对乳腺的刺激可能也有关系。生理性乳房发育可自然消退。除生理性外,男子乳房发育可以是许多原发疾病的临床表现之一。1982年上半年,我们应用放射免疫技术测定了10例病理性男性乳房发育症患者的睾酮、雌二醇,黄体生成素水平,现简要报告如下,并试就本病的发病机制进行讨论。研究对象与方法一、对象 1.患者。本文10例男性病理性乳房发育症(见表1)均为1982年上半年在我院门
Male gynecomastia accounts for more than 65% of male breast diseases. Most of the clinical findings are physiological. It is found in boys, newborns and men during the developmental period, especially in developing boys, and the incidence rate is more than 60% . It is reported that the peak incidence of 14 years, an average of 1 to 2 years. Physiological male breast development is caused by a transient sex ratio of androgens and hormones, in addition, with growth hormone, adrenocorticotropic hormone stimulation of the breast may also be related. Physiological breast development can subside. In addition to physiology, male breast development can be one of the clinical manifestations of many primary diseases. In the first half of 1982, we used radioimmunoassay to determine the levels of testosterone, estradiol and luteinizing hormone in 10 patients with pathological male breast development. We briefly report the following and discuss the pathogenesis of this disease. Research objects and methods First, the object 1. Patients. This article 10 cases of male pathological breast development (see Table 1) are in the first half of 1982 in our hospital door
