Contraceptive Research

Updated: Nov 24, 2020

The news is in!


New research shows that women who stop using some forms of contraception may have to wait several months before their fertility returns.


This large US and Danish study used data from almost 18000 women. It found the longest delays in return to fertility were in those who had used injectable long-acting contraceptives (it was 5-8 menstrual cycles for fertility to return) and the shortest was in those who had used hormonal or copper intrauterine devices (IUDs aka coils) or contraceptive implants.


Although return to fertility times varied depending on the contraceptive method used there were short delays in the return to fertility, the study found there was no lasting effect of long term use with actual probability of conceiving.
