雄性的性能随年龄增长而减退,是长期以来众所周知的,但是医生们尚未揭晓其原因。最广泛的可接受的解释是年龄达到二十或三十岁这个高峰之后,性荷尔蒙睾丸激素的水平下降,产生实际上的“雄性绝经”。然而,理论已经提出了异议。S·密查尔·哈门、P·铁塔罗斯博士和国家年龄研究院的社会学家克莱德·E·马丁,研究了从二十五到八十九岁的73个人,证实说随年龄增长性能逐渐减弱,可是三十岁后睾丸激素的水平却非常明显地保持稳定。如果没有雄性绝经这回事,那么是什么引起性的衰退呢?哈门猜测至少是因为传递信息到庞杂的神经
Male performance has diminished with age and is well known for a long time, but doctors have not revealed its cause. The most widely accepted explanation is that after the peak of 20 or 30 years of age, the level of sex hormone testosterone drops, resulting in an actual “male menopause.” However, theory has raised objections. Dr. Michel Hammem, Dr. P. Tieta Rose, and Clay E. Martin, a sociologist at the National Institute of Ages, studied 73 individuals from 25 to 89 years old and confirmed that with age Growth performance is diminishing, but the testosterone level after 30 years of age is very clearly stable. If there is no such thing as male menopause, then what caused a sexual decline? Harmony speculation, at least because of the transmission of information to the complex nerve
