补充资料：精液量过少不育
精液量过少不育
病名。男性不育症之一。正常 健康男性一次排精的精液量应是2～6ml，少于1ml者为精液量过少。但性交次数频繁亦 可使精液量暂时性减少。Dubin等(1971年)统计，由于精液量不足所引起的不育症约为18% 。精 浆由精子的介质和营养的来源，精浆中还含有稳定精液pH的缓冲物质，能保护精子在酸性阴 道分泌物内存在。大部分精浆是精囊和前列腺分泌，精子仅占一次精液量的1%。精浆能稀释 附睾中的精子。精液量过少一方面可使精子失去活力而丧失功能，另一方面也可使精子活 动 所需要的介质减少，性交后精子不能顺利到达宫颈，均可造成不育。精液减少的原因可有 ：① 性腺功能减退和内分泌不足。②附属性腺的感染，影响分泌。③尿道狭窄、尿道憩室使精液 不能完全泄出。明确引起精液量不足的病因，对治疗本病十分重要。因性腺功能减退的精液 量不足，可用人绒毛膜促性腺激素(HCG)2000～4000IU，每周2次，肌肉注射，共8周 。消除附属性腺感染和精液不能完全排出的原因，也可使精液增加。有时因射精次数频繁而 造成精液量减少，所以禁欲数天后，再次性交，可使精液量和精子增加。可参男性不育症条 。
