Answer:
The scientific understanding of the menstrual cycle of human females can help as a contraceptive measure. Periodic abstinence is one method in which the couples avoid sexual intercourse from day 10 to 17 of the menstrual cycle because ovulation occurs at this time. As chances of fertilisation are very high during this period, it is called the fertile period. Therefore, by abstaining from coitus during this period, conception could be prevented.
