15岁女孩下面是长什么样子?15岁女孩外阴是什么样子?(1)

 


1、15岁女孩外阴

 

女性生殖器按其解剖位置不同,分为内、外两大部分。内生殖器主要是卵巢、输卵管、子宫及女性私处;外生殖器包括阴阜、大小阴唇、女性私处、前庭及会阴等。这些在青春期前发育非常缓慢,进入青春期后,在促卵泡生成激素、促黄体生成素及性激素的推动下,内外生殖器均迅速发育。

卵巢是主要的性器,为灰白色扁平椭圆体,8岁时小而光滑,8-10岁时开始发育,以后呈直线上升。月经初潮时,卵巢的重量仅为成年人的30%,之后继续增大,17-18岁时卵巢发育基本成熟。卵巢的功能有两方面:一是产生生殖细胞——卵子;二是产生性激素,包括雌激素与孕激素。

因此说,卵巢既是女性内生殖器,也是内分泌器。 子宫在10岁左右开始较快地发育,18岁时接近成年人水平。子宫内膜在卵巢激素的作用下呈周期性的变化,并形成月经。女性私处变长变宽,颜色变为灰色,粘液腺发育并分泌大量分泌物。女性私处分泌物由小儿期的碱性转变为酸性。

外阴由幼稚型向成年人型过渡,阴阜隆起,阴毛出现,大小阴唇变肥厚,并出现色素沉着。女性私处口有一层薄膜覆盖,称为“处女膜”,处女膜中间有孔,此孔的大小因人而异,小的连手指都不能通过,大者可容纳两指。处女膜厚度一般为2毫米左右,个别人可很薄,剧烈运动或不慎碰撞会女性私处均可自行破裂,一般大多在初次同房时破裂,并伴有少量的出血。为此,不能以初次同房的出血与否,作为判断是否为处女的唯一依据。

第一次出现月经叫月经初潮。月经初潮是女孩子青春期发育的重要标志。月经初潮的年龄一般在10-16岁,以13-15岁为多,但个体差异很大,它受遗传、营养、情绪、环境、气候等因素的影响。初潮时,卵巢功能尚不稳定,因此初潮后月经周期并不规律,大约在1年内才逐渐转为规律的每月一次。月经期一般3-5天,月经周期28-35天,如月经周期延长到6个月以上或一次经期超过11天,均属不正常。青春期女性,随着生殖器官发育,第二性征出现。其出现先后顺序是:乳房最先发育,阴毛出现和乳房发育基本同步,腋毛的出现比阴毛晚半至1年左右。

2、少女外阴保健注意

其一,注意女性私处卫生。少女进入青春期后,随着月经的来潮和白带的分泌,少女对于此往往茫茫然,一时不知所措,由此易患青春期女性私处炎。因此,应注意经期卫生,正确使用消毒后的卫生纸巾,内裤要在日光下照晒,借以紫外线消毒;经常洗澡;睡前用温水清洗外阴,洗盆专用;大便后,手纸应由前向后擦,小便后用卫生纸擦干净。

其二,防止罹患“时装性女性私处炎”。青春少女随着审美观念的增强,追求体形美,故各种体形裤倍受青睐。此类裤子裤裆瘦短,布质厚,弹性不佳,透气不良,这就使得前有尿道口、后有肛门的女性私处倍受窘迫,女性私处的分泌物不得排泄,会女性私处处于温热、潮湿的状态,各种致病菌在此环境下最容易生长、繁殖,容易罹患时装性女性私处炎。因此要少穿或不穿体形裤,合理着装,尽量选用合体、布料弹性好、透气良的时装,以防后患无穷。

其三,洁身自爱,守身如玉。毋庸讳言,近年来,个别少女出于种种原因,过早地发生了性行为,患上了性病性女性私处炎。对此,少女应自强、自尊、自爱,正确认识人生价值观,洁身自爱、守身如玉,杜绝性乱。

其四,合理应用抗生素。少数少女长期大剂量应用抗生素(广谱)和激素治疗某些疾病,导致体内菌群失调而患霉菌性女性私处炎。因此,少女患炎性疾病,选用广谱抗生素治疗时,请遵医嘱,尽量不与激素合并用药。

其五,防止性病的间接感染。少女在公共浴所洗浴时,应自带浴盆、浴巾,尽量淋浴而不要盆池浴,防止女性私处滴虫、淋病菌或其他性病等间接感染,同时亦应掌握相应的性病知识,防止性病的间接接触感染。
