Answer

Assertion is true, but reason is false.

Explanation:

Periodic abstinence is a natural method of birth control in which the couples avoid or abstain from coitus (copulation or intercourse) from day 10 to 17 of the menstrual cycle because ovulation can occur during this period. The chances of fertilisation are very high during this period, therefore, it is called the fertile period.
