超声波用于计划生育,国内、外学者都已做了大量的研究工作,证明它能抑制动物和人睾的精子发生,而不影响精原细胞和间质细胞,故抑制生精是可逆的,对性功能却无妨碍.这些有效、安全、可逆、无痛和使用方便等优点,认为有可能作为男性避孕的一个较好的方法.但超声波节育的作用机理,实验报告不多,Fahim M S认为:“超声波透热是最好的热源;超声波是给热的最有效的方法;超声波透热具有热和机械的复合效应”.对此,我们理解为以热作用为主,伴有机械效应.国内于天文等
Ultrasound is used for family planning. Domestic and foreign scholars have done a lot of research work to prove that it can inhibit the spermatogenesis of animals and humans without affecting spermatogonia and interstitial cells, so inhibiting spermatogenesis is reversible. There are no obstacles to sexual function. These are effective, safe, reversible, painless, and easy to use. They are considered to be a good method for male contraception. However, there are few experimental mechanisms of ultrasonic birth control, and Fahim MS thinks : “Ultrasonic diathermy is the best source of heat; ultrasound is the most effective way to give heat; ultrasonic diathermy has the combined effects of heat and mechanics.” In this regard, we understand that it is mainly thermal effects, accompanied by mechanical effects. Domestic in astronomy, etc.
