“…These delays to fertility return due to the ovulation suppressive effect of DMPA have been recently documented (Taylor et al. 2022). Although an injectable may be labeled as providing protection against pregnancy for three months, the return to fecundity after discontinuation is slow and the WHO Selected Practice Recommendations for Contraceptive use states that a repeat injection can be given up to four weeks late without requiring additional contraceptive protection (World Health Organization 2016).…”

“…For injectable users who do not return to receive their subsequent injection or who discontinue their use (possibly with the intention of getting pregnant), fertility typically returns within 9-10 months, with an estimated median delay to conception of 5.5 months from the time of the last injection (Garza-Flores et al 1985;Halpern et al 2021;Mansour et al 2011;Pardthaisong 1984;World Health Organization 1997).

Adjusting Injectable Contraceptive Use for Months Since the Last Injection

Injectables are one of the most popular methods of contraception worldwide, particularly in sub‐Saharan Africa. An advantage of injectables over shorter‐acting methods is that they provide additional flexibility by not requiring re‐supply as frequently. However, there is a risk that injectable users may delay their next injection and may therefore have reduced or no protection from pregnancy. In surveys, women may report that they are using contraception in the form of injectables when the time since they had their last injection (more than four months) would imply that they have reduced protection against the risk of pregnancy. We carried out two field studies in urban Malawi, and we record reported injectable contraceptive use while also asking the number of months since women received their last injection. We observe that 13.8 percent of women who report using injectables also report that they received their last injection more than four months ago, and 11 percent report that they received their last injection more than six months ago. Our analysis highlights the need for additional follow‐up with women who report using injectables in surveys to confirm whether they are, in fact, using the method effectively.
