What are the different methods of contraception?

(N/A) Contraceptive methods are broadly classified into the following types:
$1$. $Natural \ methods$: These involve avoiding the meeting of sperm and ovum. For example, the periodic abstinence method involves avoiding sexual intercourse from day $10$ to $17$ of the menstrual cycle, as ovulation is expected during this period, making the chances of fertilization high.
$2$. $Barrier \ methods$: These prevent the physical meeting of sperm and ovum using barriers. Examples include condoms, which are thin rubber coverings for the penis in males or the vagina in females.
$3$. $Oral \ contraceptives$: These involve taking tablets or drugs orally. They contain small doses of hormones that prevent the release of eggs (ovulation), thereby preventing fertilization.
$4$. $Intrauterine \ devices \ (IUDs)$: Devices like the $Copper-T$ or loops are placed in the uterus to prevent pregnancy.
$5$. $Surgical \ methods$: These are permanent methods used to block gamete transfer. $Vasectomy$ involves blocking the $vas \ deferens$ in males to prevent sperm transfer. $Tubectomy$ involves blocking the $fallopian \ tubes$ in females to prevent the egg from reaching the uterus.
