Answer 1

Methods of contraception used by humans are :
Natural: Here sexual intercourse is avoided between 10th to 17th of the menstrual cycle as during this period ovulation is expected. Therefore, chances of fertilization are very high.
Barriers: Here a mechanical barrier is created so that the sperms cannot penetrate the egg. It 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, which causes hormonal imbalance of the body.
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.
