De patenterede progestiner bruges i hormonel prævention som p-piller, minipiller og hormonspiral. Forskningen i bivirkninger ved hormonel prævention giver derfor også et indblik i deres skadevirkninger. Ofte vil du få at vide, at progestinerne i hormonel prævention “svarer til” eller “erstatter” kvindens eget progesteron, som om det er “næsten det samme”. Men der bruges ikke naturligt progesteron i hormonel prævention – af den simple grund, at progesteron fremmer fertiliteten og derfor slet ikke kan bruges til formålet. Det er et helt andet stof med helt andre virkemåder. De patenterede progestiner forhindrer graviditet, blandt andet ved at forhindre produktionen af progesteron.
