What is vasectomy and tubectomy ?Is there is any effect on body? What happens with The ova released during tubectomy? and same with sperm

Dear Sahil
 
Vasectomy(For males)
A vasectomy is a form of birth control. It prevents sperm from being released during ejaculation. During the procedure, the vas deferens are cut or blocked. The vas deferens is the duct that carries sperm from the testicles to the urethra.
Tubecromy (for Females)
A tubectomy refers to the blocking or cutting a small portion of the fallopian tubes. These tubes are roughly ten centimeter long structures, present within a woman’s abdomen and are attached to either side of the uterus. They open into the uterus at one end and on to the ovaries at the other end. The main function of this tube is to carry the ovum (egg) – after it is released from the ovary – into the uterus to help it fertilize.
