<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;">今日<span style="color: black;">专题</span></strong></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">“洗精”是<span style="color: black;">咱们</span>对优选精子的精液处理技术的通俗叫法。“洗精”到底是怎么洗的呢?跟“洗<span style="color: black;">果蔬</span>”、“洗牌”哪个更接近<span style="color: black;">有些</span>呢?其实都不是呢,下面<span style="color: black;">咱们</span>来<span style="color: black;">瞧瞧</span>,试管婴儿中的“洗精”是怎么回事?</span></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的新技术。</p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">重点</span>用于辅助生殖技术中的试管婴儿治疗和人工授精治疗,是<span style="color: black;">经过</span>一定的程序优选精子。它能把精子、<span style="color: black;">卵细胞</span>同其他物质如白血球细胞、精液等<span style="color: black;">掰开</span>,而<span style="color: black;">海量</span>病毒恰恰正是存在于精液中间的。艾滋、乙肝、丙肝、梅毒等病毒携带者的病毒存在于精浆<span style="color: black;">或</span>血液中,但精子、<span style="color: black;">卵细胞</span>却是健康的。</p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">精子洗涤的<span style="color: black;">全部</span>过程约需2个小时,经过洗涤<span style="color: black;">能够</span><span style="color: black;">得到</span>高比例的、形态正常的、活动力强的精子,<span style="color: black;">这般</span><span style="color: black;">优秀</span>的精子才<span style="color: black;">能够</span>用于试管婴儿。</span></p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">常用的精子洗涤<span style="color: black;">办法</span>有三种:</span></p><img src="https://mmbiz.qpic.cn/mmbiz_png/Ljib4So7yuWia9kYpoibKoAcHL1fGLVHWWcqBbvgibBHtoY4Su39CzTNcBbecPECtohJLDIY3xLuXAnicqKRj3Rr0tQ/640?wx_fmt=png&tp=webp&wxfrom=5&wx_lazy=1&wx_co=1" style="width: 50%; margin-bottom: 20px;">
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><img src="https://mmbiz.qpic.cn/mmbiz_png/Ljib4So7yuWjd6TfZvPvCFGLSz5KfiaIyBbfp3pTicAGkqto3hdN69J5SCzwmpk2Qns9q3SpFFektZWpBBOLHRPaw/640?wx_fmt=png&tp=webp&wxfrom=5&wx_lazy=1&wx_co=1" style="width: 50%; margin-bottom: 20px;"></p>01<strong style="color: blue;">简单的洗涤法</strong>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">便是</span>用培养液稀释精液标本,直接离心,收集沉淀的精子团,该<span style="color: black;">办法</span>可回收多的精子,但夹杂死精子和其他细胞碎片;</p>
02<strong style="color: blue;">直接上游法</strong>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">是<span style="color: black;">按照</span>精子的泳动能力<span style="color: black;">选取</span>精子。将培养液加到液化精液上方,<span style="color: black;">亦</span><span style="color: black;">能够</span>将精液加到培养液的下方,活动的精子会自动游泳到培养液里表面<span style="color: black;">呼气</span><span style="color: black;">鲜嫩</span>空气,将聚集在培养液表层上方的<span style="color: black;">优秀</span>精子收集备用;</p>
03<strong style="color: blue;">非连续密度梯度离心法</strong>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">将精液<span style="color: black;">安置</span>在<span style="color: black;">区别</span>密度梯度培养液的上方,在离心过程中<span style="color: black;">因为</span>密度<span style="color: black;">区别</span>而分离,常用上层40%和下层80%的密度梯度液,加上活动精子主动游动,穿过梯度液在离心管底形成一个松软的沉淀团,可<span style="color: black;">得到</span>部分活力很好的精子,且不含碎片、白细胞、非精子细胞和退化的生精细胞。</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;"><span style="color: black;">通常</span>生殖中心的<span style="color: black;">大夫</span>会<span style="color: black;">按照</span><span style="color: black;">病人</span>的<span style="color: black;">详细</span><span style="color: black;">状况</span>进行<span style="color: black;">选取</span>,总的原则<span style="color: black;">便是</span>制定个体化<span style="color: black;">方法</span>,<span style="color: black;">尽可能</span><span style="color: black;">选取</span>操作简单快速,离心力低,操作轻柔,以减少对精子的<span style="color: black;">损害</span>,尽可能除去死精子和其他细胞如白细胞和细菌等。</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;"><span style="color: black;">日前</span>比较常用的是密度梯度离心法。其原理是: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。</span></p><img src="https://mmbiz.qpic.cn/mmbiz_png/Ljib4So7yuWia9kYpoibKoAcHL1fGLVHWWcQgcAdTV0FA1n7793eCuM1fNJzTkvg2yYOUpWqvGu0MmbeApIdyfo6Q/640?wx_fmt=png&tp=webp&wxfrom=5&wx_lazy=1&wx_co=1" style="width: 50%; margin-bottom: 20px;">
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;"><span style="color: black;">大概的操作<span style="color: black;">过程</span>如下图示:</span></strong></p><img src="https://mmbiz.qpic.cn/mmbiz_png/Ljib4So7yuWia9kYpoibKoAcHL1fGLVHWWcqBbvgibBHtoY4Su39CzTNcBbecPECtohJLDIY3xLuXAnicqKRj3Rr0tQ/640?wx_fmt=png&tp=webp&wxfrom=5&wx_lazy=1&wx_co=1" style="width: 50%; margin-bottom: 20px;">

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><img src="https://mmbiz.qpic.cn/mmbiz_jpg/5CVck011cY6qicrulDwbgI7iba9IWZ9icW0dqEDoAmSxVZa4zj30g4M6N70dWDYWGl4y0uYrIBCdSF5X4hCMBOutw/640?wx_fmt=jpeg&tp=webp&wxfrom=5&wx_lazy=1&wx_co=1" style="width: 50%; margin-bottom: 20px;"></p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">当然,<span style="color: black;">针对</span>极重度少精子症<span style="color: black;">病人</span>或手术穿刺取精的<span style="color: black;">病人</span>,密度梯度离心法是不适合的。除密度梯度离心法之外,<span style="color: black;">按照</span>取精的形式、精液质量的<span style="color: black;">区别</span>,可能还会<span style="color: black;">运用</span>直接上游法、离心后上游法、直接在高倍视野中找精子等<span style="color: black;">办法</span>。</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">总的<span style="color: black;">来讲</span>,试管婴儿过程中洗涤精子是非常<span style="color: black;">要紧</span>的一个环节,其能有效<span style="color: black;">提高</span>男性精子活力和质量,<span style="color: black;">加强</span>受精成功率,降低畸形胚胎的形成,从而达到优生优育的目的。</span></p>
