Answer 2

There are two types of contraceptive methods.

i) Natural methods

ii) Artificial methods

Natural Methods

Avoiding the coming together of ovum and sperm

Periodic abstinence:Avoiding coitus from days 10 to 17 of the menstrual cycle

Coitus interruptus: Withdrawal of penis before ejaculation

Lactational amenorrhea: It is the absence of menstruation during lactation. So, in the lactation period, the chances of conception are almost zero.

Artificial Methods

Physically preventing the coming together of ovum and sperm

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)
