If you are not on the birth control pill you ovulate inalmost every cycle, if you are in you mid to late 40s you ovulate significantlyless frequently, but if you are having regular cycles, you are still ovulating.If you are on birth control pills ovulation is decreased, but not completelyeliminated. For birth control pills with the 30 to 35 mcg of estrogen theovulation rates have been reported to be about 2%, and for pills with only 15to 20 mcg the ovulation rates are about 1.1%. It should be that higher estrogendoses produce less ovulation, and it could be the way these statistics areinterpreted that produces these small differences. Since pregnancy is preventedin ways other than preventing ovulation, most all birth control pills have thesame effectiveness.
