摘 要 目的:探討精子頂體酶活性與精液有關(guān)參數(shù)間的關(guān)系。方法:選取男性不育癥患者80例收集精液,檢測精液各項參數(shù)及精子頂體酶活性,按照精子頂體酶活性分為正常組(n=45)和異常組(n=35);分析兩組精液相關(guān)參數(shù)的差異及頂體酶活性與精液相關(guān)參數(shù)的相關(guān)性。結(jié)果:不同頂體酶活性患者在精子密度、精子活動率、a+b級精子、c級精子、d級精子及精子正常形態(tài)間存在顯著差異(P<0.05),不同頂體酶活性患者在年齡、禁欲時間、精液量、液化時間及鋅含量方面差異無統(tǒng)計學(xué)意義(P>0.05);精子頂端酶活性與精子密度、精子活動率、a+b級精子所占比例、精子正常形態(tài)所占比例呈正比,與c級精子所占比例呈反比。結(jié)論:精子頂體酶活性與精子質(zhì)量相關(guān)的多項指標存在相關(guān)性,可作為評估精子質(zhì)量的指標。

ABSTRACT Objective: To explore the correlation between the activity and the quality of sperm acrosin. Methods: Semen from eighty patients with male infertility were selected and the parameters of semen and sperm acrosin activity were detected. All the patients were divided into a normal group (n=45) and an abnormal group (n=45) based on their sperm acrosin activity. The correlation between the activity and the parameters of sperm acrosin in the two groups were analyzed. Results: There were significant differences in sperm density, sperm motility, a+b level sperm, c level sperm, d level sperm and normal sperm forms in patients with different sperm acrosin activity (P<0.05). No significant differences in age, abstinence time, seminal fluid quantity and zinc content were found in patients with different sperm acrosin activity (P>0.05). Sperm acrosin activity was proportional to sperm density, sperm motility, the proportion of a+b level sperm and normal sperm forms, but was in reverse proportion to the proportion of c level sperm. Conclusion: There exists correlation between sperm acrosin activity and multiple indicators related to sperm quality, so sperm acrosin activity can be used as an indicator to assess sperm quality.
KEY WORDS infertility; sperm quality; sperm acrosin activity; semen analysis
流行病學(xué)調(diào)查顯示,我國育齡夫婦不育癥的發(fā)病率為15%~20%,其中約50%與男性因素有關(guān)[1]。評價男性生育力的常用方法為精液常規(guī)分析(semen analysis, SA),但分析結(jié)果受主觀因素影響較大,不能全面反映精子生育力。頂體酶(acrosin)是一種影響受精結(jié)局的關(guān)鍵酶,同時也是直接反映活精子質(zhì)量的重要指標[2]。本研究通過分析精子頂體酶活性與精液有關(guān)參數(shù)間的關(guān)系,探討頂體酶在男性不育癥診斷中的臨床應(yīng)用價值。
1 資料與方法
1.1 一般資料
選取我院2015年1月—2017年9月來我院就診的男性不育癥患者80例,年齡27~38歲,平均年齡(32.1±4.6)歲;主訴身體健康,婚后或同居不避孕正常性生活2年以上未育;排除因女方因素導(dǎo)致的不育,性功能障礙者,有家族遺傳病史者,有明顯睪丸、附睪及輸精管異常者,精神疾病患者及不能配合完成研究者。所有患者對本研究內(nèi)容及目的知情同意并自愿參與。
1.2 標本采集
采集精液受檢前禁欲2~7 d,手淫法取精液于Ep管內(nèi),精液白細胞計數(shù)<1×106/L,肉眼未見紅細胞且液化時間小于60 min為合格精液,置37 ℃恒溫液化后作精液檢測。
