Does prolonged use of contraceptives cause fibroids?


The cause of fibroids is debated but it is thought to be a combination of acquired genetic change plus the effects of hormones and growth factors, possibly related to a response to ischaemic injury at the time of menses.

They start as multiple, single-cell seedlings distributed throughout the uterine wall. These then increase in size very slowly over many years, stimulated by oestrogens and progestogens.

So its important to note that contraceptives do not case fibroids.


While taking birth control pills can reduce the heavy flow, they will not reduce the size of the fibroids. In fact, birth control pills may cause the fibroids to grow larger. Fibroids are very responsive to hormones such as estrogen and progesterone.
