卵巢是一个很小的器官,重5克左右,约3×2×1厘米大小,形状很似杏仁,盆腔左右各一个,结构比较复杂,因它来自体腔上皮的生殖嵴,常含有各种胚胎残余组织或睾丸成分;在胚胎发育期与泌尿系十分接近,部分中肾组织可迷入其内;本身又有生发上皮、卵泡及间质等不同特性之组织。其生理功能也较复杂,在丘脑下部及垂体控制下,可发生周期性变化,每月排卵一次。由于卵巢的结构及功能复杂,故发生肿瘤的机会也多;因其位于盆腔深部,早期常无明显症状,不易被发现,等长到一定大小能查到时,则常属晚期,
Ovary is a small organ weighing about 5 grams, about 3 × 2 × 1 cm in size, shape is very similar to almonds, pelvic around each one, the structure is more complex, because it comes from the genital epithelium genital ridge, often containing a variety of embryos Residual tissue or testicular composition; very close to the urinary system during embryonic development, part of the kidney tissue can be fascinated inside; itself has germinal epithelium, follicles and interstitial tissue of different characteristics. Its physiological function is also more complex, under the control of the hypothalamus and pituitary, cyclical changes occur once a month ovulation. Due to the complex structure and function of the ovary, so the chance of tumor occurs; because it is located in the deep pelvic, often no obvious symptoms early, difficult to be found, such as the length of a certain size can be found when the often late,
