【摘要】目的:評估維生素E作為抗氧化劑和他莫昔芬作為抗雌激素組合治療對精子濃度和活力的可能效果,并與只用一種藥物的特發(fā)性少弱精子癥患者進(jìn)行對比。方法:90例特發(fā)性少弱精子癥患者隨機(jī)平均分為三組,A組:服用維生素E(300mg/d)6個月;B組:服用他莫昔芬(20mg/d)6個月;C組:服用相同劑量的兩種藥物組合6個月。所有患者均接受了以下內(nèi)容:詢問病史、全身和生殖器檢查、精液分析、血清促卵泡激素、總睪酮、陰囊超聲。精液檢查在治療開始時、治療結(jié)束后3個月和結(jié)束后6個月分別進(jìn)行。結(jié)果:與治療前相比,服用維生素E的小組,6個月的治療后平均精子濃度沒有顯著增加。另一方面,在6個月的治療后,其他兩個小組的平均精子濃度顯著改善,且聯(lián)合治療組更明顯(P<0.01)。在前向運(yùn)動精子比例方面,所有患者群體中都有所改善,且在聯(lián)合治療組更明顯。對于服用維生素E組,這一數(shù)字是(28.07±9.65)%(P<0.01)。對于服用他莫昔芬組,這一數(shù)字為(33.33±14.10)%(P<0.01),在聯(lián)合治療組,是(40.50±17.54)%(P<0.01)。結(jié)論:結(jié)合抗氧化和抗雌激素療法對于我們選定的患有不明原因的少弱精子癥患者治療有效。

【Abstract】Objectives: To evaluate any possible effects of combining vitamin E as antioxidant and tamoxifen citrate as antiestrogen on spermatozoa concentration and motility in comparison to give either of medications alone in patients with idiopathic oligoasthenozoospermia. Methods: Ninety patients with idiopathic oligoasthenozoospermia were randomized into equally three groups: Group A received vitamin E( 300 mg/ day ) for 6 months; Group B received tamoxifen citrate (25 mg / day) for 6 months; Group C received combination of both drugs in the same doses for 6 months. All patients were subjected to the following: history taking, general and genital examination, semen analysis, serum FSH, total testosterone, and scrotal ultrasound. Semen examination was performed at the start of treatment and was repeated after 3 months and after 6 months of treatment. Results: Compared with before treatment, vitamin E group was insignificantly increased in mean sperm concentration after 6 months of treatment. On the other hand, there was a significant improve in mean sperm concentration in the other two groups after 6 months of treatment, with more significance in combination therapy group (P < 0.01). In the aspect of percentage of progressively motile sperm, the percentage of progressively motile sperm improved in all patients groups, with more significance in combination therapy group. In vitamin E group, it was 28.07±9.65% (P < 0.01). For those in clomiphene citrate group, it was 33.33±14.10% (P < 0.01) and 40.50±17.54% (P < 0.01) in combination therapy group. Conclusion: Combining antioxidant and antiestrogen therapy is a valid option for the treatment of a selected group of men with unexplained isolated oligoasthenozoospermia.

世界衛(wèi)生組織(WHO)對不孕不育的定義是:一對夫妻在同居了1年或以上的有規(guī)律且未避孕的性生活后仍然無法懷孕[1]。我們對導(dǎo)致男性不育的原因仍然知之甚少,而患者往往診斷為特發(fā)性少弱精子癥[2]。現(xiàn)在一般認(rèn)為,男性不育癥的最常見的原因是特發(fā)性少弱精子癥[3]。這些患者目前并沒有與生育問題相關(guān)的既往史,并且他們的體檢及內(nèi)分泌化驗結(jié)果正常。
目前已經(jīng)研發(fā)了多種藥物以試圖改善精子質(zhì)量,進(jìn)而改善在這種情況下的男性生育潛力[4]。常用藥物包括抗雌激素類藥物、雄激素治療、左旋肉堿和抗氧化劑。……
