`star` As no medicines or devices are used in these methods, `color{Violet}"side effects"` are almost `color{Violet}"nil"`.
`star` `color{Violet}"Chances of failure"`, though, of these methods are also `color{Violet}"high"`.
`star` They can be carried out by various means describes below.
● `color{Brown}"Periodic abstinence"`:
`star` It is one such method in which the couples avoid or `color{"Violet}"abstain from coitus"` from day `color{Violet}"10 to 17"` of the menstrual cycle when `color{Violet}"ovulation"` could be expected.
`star` As chances of fertilisation are very high during this period, it is called the `color{Violet}"fertile period"`. Therefore, by abstaining from coitus during this period, `color{Violet}"conception"` could be `color{Violet}"prevented"`.
● `color{Brown}"Withdrawal or Coitus interruptus"` :
`star` It is another method in which the male partner `color{Violet}"withdraws"` his penis from the vagina just before ejaculation so as to `color{Violet}"avoid insemination"`.
● `color{Brown}"Lactational Amenorrhea"`:
`star` Such (`color{Violet}"absence of menstruation"`) method is based on the fact that ovulation and therefore the cycle do not occur during the period of `color{Violet}"intense lactation"` following parturition.
`star` Therefore, as long as the mother `color{Violet}"breast-feeds"` the child fully, chances of conception are almost `color{Violet}"nil"`.
`star`However, this method has been reported to be effective only upto a maximum `color{Violet}"period of six months"` following parturition.
