Menopause typically occurs between the ages of 45 and 55 and marks the end of a woman's reproductive years. After menopause, most women are no longer able to get pregnant naturally. However, pregnancy is still possible for some women even years after their last period.
There are two important things to understand about fertility after menopause:
- The onset of menopause is diagnosed retrospectively, after 12 consecutive months without a period. This means it's difficult to pinpoint exactly when fertility ends.
- In rare cases, women can ovulate and release an egg even after menopause. If conception occurs, pregnancy is possible.
How Long After Menopause Is Pregnancy Possible?
Pregnancy during perimenopause or in the years shortly after menopause is rare but can happen. Here's what the research shows about how long post-menopausal fertility lasts:
- Up to 2 years after the last period, pregnancy remains possible for some women. Ovulation and fertilization can sporadically occur even in peri- and early post-menopause.
- Up to 5 years after the last period, a few unique cases of natural pregnancy have been reported. These conceptions likely happen if ovulation unexpectedly resumes years after menopause.
- After 5 years without a period, pregnancy is still biologically possible but has almost never been documented. The upper limit is difficult to quantify but is likely around 8-10 years after the last period.
Risk Factors That Extend Post-Menopausal Fertility
Some women remain capable of getting pregnant longer after menopause than others. Factors that play a role include:
- Age at menopause - Women who experience menopause at later ages (in their late 40s or 50s) may retain ovarian function longer.
- History of irregular cycles - Women who always had irregular menstrual cycles may be more likely to ovulate sporadically after menopause.
- Use of contraception - Using contraceptives, especially hormones like birth control pills, can make determining when menopause occurs more difficult.
- Hormone therapy - Post-menopausal hormone therapy with estrogen and/or progesterone may stimulate ovarian function in some women.
- Ethnicity - Asian and Hispanic women on average experience menopause later in life compared to White women.
In summary, fertility comes to an end around menopause but a small possibility of conception exists for up to 5 years after the last menstrual period. While extremely rare, natural pregnancies leading to live births have even been documented in women over age 50. Any woman of reproductive age who does not wish to become pregnant should continue using contraception even after peri-menopause begins.
What Should I Do If I Want To Get Pregnant After Menopause?
If you'd like to try having a baby after menopause has occurred,
in vitro fertilization (IVF) using donor eggs may enable you to carry a pregnancy. The uterus continues to be receptive to implantation for years after natural fertility declines. Before attempting post-menopausal pregnancy with IVF, a full health screening is recommended.
