女孩发育的年龄一到，特别是少女胸部发育期之时，总觉得胸前的隆起很是刺眼，有的因此养成颔胸驼背的坏习惯。那么少女胸部发育与女生阴毛发育在时间上有没有相关性呢？
\n
少女乳房的发育，主要由卵巢分泌的雌激素来控制，这也是是月经来潮的前奏之一。10岁左右得时候，乳房和乳头均隆起，出现乳晕。在长达5年的时间里，逐渐增大增高，乳晕增宽色变深，乳头突起形成个性化的凸起外观。如果两侧乳房出现不对称，一侧乳房尤其是左侧乳房先发育属于正常现象，不必过分担心。即便是到成年后，两侧乳房不完全对称也属正常现象。乳房本身没有肌肉，靠皮肤和结缔组织支撑，悬吊附着的软组织容易松弛，时间一长，就会造成乳房逐渐下垂且不能恢复原状。
\n女生阴毛的发育要比胸部发育晚1～2年，但它的生长的速度比乳房要快，在不到3年的时间左右，分布满阴阜的倒三角区域。
\n在此期间，女孩子的身高会出现飞速增长，常常超过同龄的男孩子。这种增长的速度通常在月经初潮前达到顶峰。
\n女孩发育其他的部位变化还包括：腿部的绒毛长成长的汗毛；出现痤疮；变声；体味变化；髋部、大腿处有脂肪堆积等。
\n女孩发育的年龄介绍：少女胸部发育与女生阴毛发育关系知识的关键点：
\n1、着宽松的服饰，既利于乳房的发育，也利于掩饰女孩对体型变化的敏感心理，预防驼背等不良体态的发生。
\n2、乳房发育到一定程度，不论大小，都应该佩带合适的胸罩，尤其是在运动的时候。理想的胸罩是既能支撑双乳，又可活动自如。
\n3、第二性征发育的阶段，应适当节制女孩的饮食，否则有可能过度肥胖。
\n4、女孩8岁以前胸部发育为“早熟”，晚于16岁仍无动静为“迟发”，这两种情况都需要检查究其缘由。
\n4、若乳房已发育成熟而阴毛还没长是极为少见的。应警惕一种叫“睾丸女性化”的两性畸形病变。有成熟的阴毛发育但乳房没有发育，应注意是否为雄激素过多或雌激素缺乏。

对于年幼的女童而言，阴道出血绝非正常现象。虽然出血偶尔是外阴明显创伤引发，往往是严重疾病的信号，需要引起母亲的重视。那么女童阴道出血怎么回事呢？

女童阴道出血的原因往往并不显而易见，需要尽快就医。女童阴道出血可能的原因包括：锐利的异物损伤了阴道壁；严重的阴道感染损伤粘膜；女孩误服了妈妈的避孕药或含有激素成分的食品；尿道口息肉；卵巢、子宫、阴道肿瘤；垂体肿瘤；肾上腺肿瘤；甲状腺疾病等内分泌异常等。
\n另外，一些在青春期前好发的卵巢肿瘤并不一定表现为阴道出血，它们可能使孩子感觉腹痛或引起大小便的异常。许多疾病的发现就是洗澡时见女孩腹围增大而发现肿瘤。
\n女童阴道出血怎么回事呢知识关键点：
\n1、10岁前女童阴道出血是异常征象，可能的原因包括：
\n1.1、损伤
\n1.2、感染
\n1.3、药物
\n1.4、肿瘤
\n1.5、内分泌异常等
\n2、及时到正规医就诊是明智的选择。

在妇科诊室看到小女孩就诊虽非常见，但也不少。她们趟在与其不相称的检查床上，进行女孩的阴道检查或女孩肛检，不久便会传来悲惨的号哭声，好在医生大都能找到症结的所在。
\n![\"女孩的阴道检查与女孩肛检\"](\"http://01luntan.com/ly_img/uimgs/1499494449051.jpg\" "\\"女孩的阴道检查与女孩肛检\\"")
再对小女孩进行妇科疾病的诊断前，医生通常会先向求医的母女询问相关情况，以便找到有价值的线索。如果需要会在较全面的体格检查基础上，进行专门的妇科检查也是必不可少的。
\n对外阴的检查，一般不会给女孩造成痛苦。但如果存在阴道内异物或炎症，医生会采用细的探棒或棉棍进行触探和取材，医生将对采集的阴道分泌物进行镜下观察和病原体的检测。如果有需要，医生会在家长的同意下用窥具进行阴道检查，用小号的窥具，一般不会损伤处女膜。如果要做更复杂的操作，一般会收住院在麻醉下进行。
\n女孩们最害怕的可能是所谓的“肛诊”。医生将一只手指插入肛门至直肠，在其配合下触摸子宫和卵巢。那感觉有些胀，有些难受，。但这也是必不可少的检查，对医生获得最初的诊断十分重要。检查时间只有十几秒，女孩应尽量放松，母亲在检查过程中，应该配合医生稳定女儿情绪。
\n女孩的阴道检查与女孩肛检知识的关键点：
\n1、超声等影像学检查虽然有很大参考价值，但基本的盆腔检查是妇科医生最重要的第一手材料。
\n2、病痛某种意义上就是指有病就难免有痛。
