Modern hormonal contraceptives containing small doses of progesterones and estrogens, when used for periods of 9-12 months, generally are not observed to cause any disruptions in the reproductive function. However, when used for periods of 2-3 years, the reproductive system usually requires a period of a few cycles to readjust itself for proper ovulation. Several months of monophasic temperatures without a secretory phase is common. In the case of usage exceeding 5 years, stimulation of ovulation with clomifen or a derivative is often necessary. These delays in the proper functioning of the reproductive organs must be taken into account in the process of family planning. As a rule, it is considered that the longer the term of use of hormonal contraceptives, the longer it takes the ovulation cycle to readjust. For those families planning future children, use exceeding 3-4 years is not recommended.
