alleryWhich surgical contraceptive (sterilization) method in the male involves the ligation of the vas deferens?
ATubectomy
BVasectomy
CDiaphragm
DCopper-T
Answer & Solution
Correct answer: B. Vasectomy
1. Surgical contraception (sterilization) is a permanent birth-control method.
2. In males the procedure is vasectomy, the ligation of the vas deferens.
3. Tubectomy is the female method, the ligation of the fallopian tube, so it is wrong.
4. A diaphragm is a barrier method and Copper-T is an intra-uterine device, so they are ruled out.
