It is the sterilisation technique by which vas deferens from the testis is cut or tied to prevent the mixing of sperm with the semen ejaculated from the *****. Semen of vasectomised males will not have sperms in them. As semen is devoid of sperms, there occurs no fertilisation of ovum produced by females.Tubectomy is a surgical method performed in females as a birth control method. It is a permanent contraceptive method. Fallopian tubes emerging out of the ovaries on either side are cut and tied. This is a permanent contraceptive method as there occurs no fertilisation in the fallopian tube. Ovum cannot reach the fallopian tube and wait there for the sperm coming to fertilise it. Contraception methods |
