Describe vasectomy and tubectomy with diagrams.
Vasectomy and tubectomy are permanent methods of contraception. They are also known as sterilisation techniques. These methods are generally advised to the male or female partner as a terminal method to prevent any more pregnancies. It blocks gamete transport and thereby prevents conception.
In vasectomy, a small part of the vas deferens is removed and then tied up through a small incision on the scrotum.
In tubectomy, a small part of the fallopian tube is removed and then tied up through a small incision in the abdomen or through the vagina. These techniques are highly effective, but their reversibility is poor.
