HIV病人的生育福音——试管婴儿洗精术
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">从<span style="color: black;">发掘</span><span style="color: black;">第1</span>例艾滋病毒感染者,到如今上百万人被感染,仅仅过了34年。而我国存活艾滋病感染大约在125万,预估新发感染者每年高达8万例</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">艾滋病<span style="color: black;">是由于</span>感染HIV病毒<span style="color: black;">导致</span>的,HIV是一种能攻击人体免疫系统的病毒。它把人体免疫系统中最<span style="color: black;">要紧</span>的CD4T淋巴细胞<span style="color: black;">做为</span><span style="color: black;">重点</span>攻击<span style="color: black;">目的</span>,<span style="color: black;">海量</span>破坏该细胞,使人体丧失免疫功能。<span style="color: black;">况且</span>艾滋病是一种<span style="color: black;">害处</span>性<span style="color: black;">极重</span>的传<span style="color: black;">患病</span>,<span style="color: black;">况且</span>截止<span style="color: black;">日前</span>还<span style="color: black;">无</span>彻底治疗的<span style="color: black;">办法</span>。</p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">HIV病毒传播途径有四条,分别是性传播、静脉注射传播、血液传播和母婴传播。<span style="color: black;">针对</span>HIV感染者<span style="color: black;">来讲</span>最痛苦的莫过于“生命得不到延续”,但洗精术的<span style="color: black;">显现</span>打破了这“规则”。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">什么是洗精术</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">洗精术<span style="color: black;">是由于</span>意大利米兰大学的奥古斯都等教授发明,从20世纪90年代中期<span style="color: black;">起始</span>,这项技术<span style="color: black;">重点</span>用于<span style="color: black;">帮忙</span>艾滋病男性感染者孕育健康的下一代。它能把个体精子与精液分离开来,而<span style="color: black;">海量</span>病毒恰恰正是存在于精液中。</p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">就拿HIV<span style="color: black;">病人</span><span style="color: black;">来讲</span>,他的病毒存在于精浆之中,但精子却是健康的,<span style="color: black;">此时</span>这就<span style="color: black;">必须</span><span style="color: black;">经过</span>医学手段,从精液中分离出健康精子,再<span style="color: black;">经过</span>和<span style="color: black;">卵细胞</span>体外结合,最后将健康的胚胎移植到母体着床妊娠,进行生长<span style="color: black;">生长</span>,<span style="color: black;">保准</span>母体和胚胎都健康安全。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">洗精术的原理</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">活的精子、死的精子、白细胞及细菌等沉降系数<span style="color: black;">区别</span>,在<span style="color: black;">必定</span>的离心力的<span style="color: black;">功效</span>下,会有<span style="color: black;">区别</span>的沉降速度,在<span style="color: black;">区别</span>的梯度液中形成区带。</p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">洗精术的流程</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">1、男性将精子取出,接入<span style="color: black;">没</span>菌取精杯,实验员将精液样本<span style="color: black;">经过</span>密度梯度及离心手段将样本分层。</p>
<div style="color: black; text-align: left; margin-bottom: 10px;"><img src="https://pic2.zhimg.com/80/v2-e693dd7bc5e1876015880f6baf866e25_720w.webp" style="width: 50%; margin-bottom: 20px;"></div>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">2、 离心后,将上清液吸出废弃,同时加入<span style="color: black;">区别</span>浓度的洗涤液,利用密度梯度离心的原理,使得杂质及活力差的精子离心后进入清液,再次重复以上<span style="color: black;">过程</span>。</p>
<div style="color: black; text-align: left; margin-bottom: 10px;"><img src="https://pic2.zhimg.com/80/v2-b5865066af4551e41eb81f48cd2a3a2d_720w.webp" style="width: 50%; margin-bottom: 20px;"></div>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">3、再次低速离心,弃去上清液,加入精子洗涤液,倾斜45度静置1小时,等待活力好的精子上游析出。最后回收上层约1ml的液体分成两部分。其中一部分用来做检测,<span style="color: black;">倘若</span>检测结果阴性,再进行后续的辅助生育。</p>
<div style="color: black; text-align: left; margin-bottom: 10px;"><img src="https://pic2.zhimg.com/80/v2-9bf9443ad5b30936ae33271ac925d65d_720w.webp" style="width: 50%; margin-bottom: 20px;"></div>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">有<span style="color: black;">非常多</span>男性担心,<span style="color: black;">这般</span>的操作<span style="color: black;">是不是</span>会影响到精子的活力与活率,从而影响到精卵的结合呢?</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">并不会,洗精术在很大程度上<span style="color: black;">保准</span>了精子的质量,离心技术<span style="color: black;">能够</span>去除精浆内抗精子抗体、死精、病原微生物等,能够筛选、<span style="color: black;">保留</span><span style="color: black;">优秀</span>精子。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">综上所述男性HIV病毒携带者<span style="color: black;">倘若</span>想要生育,先运用精子洗涤技术去除精液中的HIV病毒,<span style="color: black;">而后</span><span style="color: black;">经过</span>试管婴儿助孕技术,成功孕育健康宝宝。</p>
