    Explain the permanent methods of birth control.

    Answer:

    Sterilisation provides a permanent birth control. It is called vasectomy in men and tubectomy in women. In vasectomy, a small part of the vas deferens is removed or tied up through a small incision on the scrotum, whereas in tubectomy, a small part of the fallopian tube is removed or tied up through a small incision in the abdomen, or through vagina. These techniques are highly effective but their reversibility is very poor.
