Your Chances of Getting Pregnant in your 20s, 30s and 40s

What are your chances of getting pregnant in each decade of your reproductive years? It’s a significant question, since the age for first-time pregnancies is rising around the world. In the US, the average age of first pregnancy is 25. In Japan, it’s 29, and in Germany, it’s 30.1Age is the most significant factor that affects a woman’s fertility. A woman’s best reproductive years are in her 20s, but that certainly doesn’t mean that it’s impossible to have a successful pregnancy in your later years.

Most women reach peak fertility between the ages of 23 and 31. After that point, fertility starts to decline in most women. At the age of 30, healthy, fertile women have a 20 percent chance of conceiving during any given cycle. That doesn’t mean that 30-year-old women only have a 20 percent chance of becoming pregnant in general; it simply means that 20 in 100 women will become pregnant within the first cycle of trying; 80 others will have to try again for the next cycle.

By the age of 31, the chances of getting pregnant begins to drop by about three percent per year, until 35, when the decline picks up speed. By age 40, a woman’s odds of conceiving are five percent per cycle, on average.2 This relationship between age and odds of conceiving are further demonstrated in the chart below.34 The percentages represent the probability of a woman becoming pregnant during her next cycle, based on her age and the number of months she’s been TTC.

AGE 3 6 9 12 24 36
25 18% 15% 12% 10% 6% 3%
30 16% 13% 11% 9% 4% 2%
35 12% 9% 7% 6% 2% 1%
40 7% 5% 4% 3% 1% .5%

While the average woman can have a baby until the age of 41, each woman is different from the next. For some women, that age is higher—it could be as high as 45. About one in four women over the age of 35 experience difficulties becoming pregnant.5 Many people believe that women reach their infertility when they go into menopause. In fact, most women lose their ability to have a successful pregnancy prior to the onset of menopause. The average age of menopause is 51, whereas many women can no longer have a successful pregnancy by the mid-forties.6 With that being said, age isn’t the only factor that impacts your fertility. Your chances of getting pregnant  may be increased through healthier habits such as moderate exercise, a well-balanced diet, controlled alcohol consumption, and avoidance of smoking and other toxins. And, if you are at an age where your fertility has already been affected, you can still discuss your options with a fertility expert.

Jade & Tanner Got Pregnant with Ava!

Thank you everyone for all the support and for sharing your stories since we announced our pregnancy on Wednesday! We are so excited! For those of you who have been following us for a while, you may have seen our past post back in November about using the @avawomen bracelet to help us get pregnant faster. We got pregnant really soon after we started using Ava! I wore the bracelet every night while sleeping and Ava told us which five days were the best days to try for a baby each month. It took so much stress out of the process and was so easy to use. Since so many of you have kindly opened your hearts to me and have shared your stories about trying to get pregnant, I wanted to share what worked for us. Also, I've partnered with Ava to get you all a $20 off coupon code: JANNERBABY I'll be using Ava for all our future pregnancies and cycle tracking between babies. Thank you, Ava.
