The average time from the last shot to return of menstrual cycles in women who stop DepoProvera is 5 calendar months. There are many ladies who take longer and one year is not unususal.
When menstrual cycles resume, the fertility of Depo-Provera users is the same as women who have stopped the IUD or oral contraceptives to become pregnant.
The average time to pregnancy in a group of ladies <30 years of age is 6 menstrual cycles.
Following Depo-Provera, there is no increase in miscarriage or birth defects.
Fertility drugs are applied "empirically" to help patients become pregnant. I liken the rationale to buying lottery tickets: if you buy two, you should have a better chance of winning. Fertility drugs work if one gives a sufficient dose to cause extra ovulations. The "downside" is the increased likelihood for multiple pregnancy using this strategy. There are no data that biology understands the rules of chance and lotteries.
