Solution
The different methods of contraception are as follows:
Natural: In this method, sexual act is avoided from the day 10th to the day 17th of the menstrual cycle as during this period ovulation is expected. Therefore, chances of fertilization are very high.
Barriers : Include condoms, diaphragms, cervical caps and vaults.
Intra uterine devices (IUDs) : They release hormones to cause phagocytosis of sperms, or they release copper ions to decrease sperm motility.
Oral contraceptive pills : They contain hormones—either progesterone or progesterone−oestrogen combination.
Surgical methods : Include vasectomy (removal of a part of the vas deferens in males) and tubectomy (removal of a part of the fallopian tubes in females)
