Question

Among all the methods of contraception, which one can prevent the implantation of the fertilized egg? 

A. Coil (mechanical) B. condom (mechanical) 

C. Spermicide (chemical) D. Vasectomy (Surgical)

Answer 1

It is because condoms are a barrier method of protection which doesn’t even allow sperms to enter the vagina. On the other hand, spermicides kill the sperms as soon as they enter vagina hence prevent fertilization. Vasectomy is a surgical method that cuts vasa deferentia thus doesn’t even allow the sperms to get ejaculated in the urethra. Thus, only coil mechanism prevent implantation.
