Definition - What does Time-to-Pregnancy mean?

Time to pregnancy refers to the length of time that it takes for a woman to get pregnant after starting to actively try to conceive. It is measured by the number of menstrual cycles it takes.

Time to pregnancy is used to estimate the ability to become pregnant. In most otherwise healthy women, the time to pregnancy range is from 1-6 cycles. If it takes longer than 6 cycles of well-timed intercourse to conceive, this may indicate that there are underlying causes impacting fertility. A diagnosis of infertility requires 12 cycles.

FertilitySmarts explains Time-to-Pregnancy

One study found that for the majority of women, it takes a few attempts to successfully conceive. On average, 1 in every 2 women get pregnant within the first 2 menstrual cycles, almost 80% were successful by the end of 6 cycles and over 90% by the end of 12 months.

Half of the women who do not get pregnant within 6 cycles get pregnant in the next 6 cycles, and the remainder usually has subfertility that requires some form of medical intervention.

A woman has a significant chance of getting pregnant only during a few days during each menstrual cycle which include the days prior to ovulation and the day of ovulation itself.
