Sterilization
Highly effective way to avoid pregnancies is a permanent solution such as Sterilization. In this procedure, a doctor or medical practitioner effectively operates and performs, Vasectomy (in males), and Tubectomy (in females).
'Vasectomy', is a surgical procedure in which a man's 'Vasa-Deferentia', an organ through which sperm travels up to seminal stream, is tied down or sealed in a manner which prevents sperms from ejaculation.
Tubectomy is a surgical procedure in females, where a medical practitioner operates on the fallopian tubes by either blocking, clamping or sealing it to avoid ova's reaching down to uterus for fertilizations.
