人精液射出后立即凝固，通常在5～10min内再液化。精液液化的生理和生化方面的原理知之不多。参与精液液化的酶可能有多种”’。精液液化时间过长（＞30min）N4被视为液化异常，称“精液不液化’域“精液液化迟缓”’‘’。精液不液化可能是引起不育或生育力低下的原因之一。本 Immediately after the injection of human semen solidification, usually liquefied within 5 ~ 10min. Sperm liquefaction of the physiological and biochemical aspects of the principle of little. Enzymes involved in sperm liquefaction may have a variety of “.” Sperm liquefaction time is too long (> 30min) N4 is considered abnormal liquefaction, said “semen liquefaction” domain “sperm liquefaction slow” ". Semen liquefaction may be one of the causes of infertility or low fertility. this
