उत्तर
Scientific understanding of the menstrual cycle can be helpful in human females as a contraceptive measure as it can help in demarking the dates during which the chances of contraception are higher. For example, periodical abstinence is one such natural method which is based on the fact that the couples avoid coitus during the 10-17 day of the menstrual cycle when ovulation is expected. Coitus can be avoided during the time span in which the chances of fertilization are higher if there is a scientific understanding of the menstrual cycle.
