A woman's peak fertility is in her teens and 20s. At age 30, fertility slowly starts to decrease. Most women don't have trouble early in the decade. In fact, even as you inch closer to your late 30s, your chance of getting pregnant within a year is around 65 percent.
ABSTRACT: The fecundity of women decreases gradually but significantly beginning approximately at age 32 years and decreases more rapidly after age 37 years. Education and enhanced awareness of the effect of age on fertility are essential in counseling the patient who desires pregnancy.
What's the average time it takes to get pregnant by age? If you take women under 37 years old with no known fertility problems who got pregnant, about 45 percent of them will have conceived within three months, 60 to 65 percent within six months, 85 percent within a year and 93 percent within 18 months.
One study found that for couples having regular unprotected sex: around 7 out of 10 women aged 30 will conceive within one year. around 6 out of 10 women aged 35 will conceive within one year. around 4 out of 10 women aged 40 will conceive within one year.
Realistically, it's more of a dip—not a nosedive—at 35. A reassuring study found that women ages 30-34 have an 86% chance of getting pregnant within one year of trying, and a 94% chance of conceiving after two years.
A woman's peak reproductive years are between the late teens and late 20s. By age 30, fertility (the ability to get pregnant) starts to decline. This decline happens faster once you reach your mid-30s. By 45, fertility has declined so much that getting pregnant naturally is unlikely.
Women lose 90 per cent of the eggs in their ovaries before the age of 30, new research has shown. The mathematical model shows that the average woman has only 12 per cent of her eggs left by the age of 30 and only three per cent by the age of 40.
Male Fertility Facts
Peak male fertility is around 25-29 years old. Sperm quality begins to decline at 30. At 45, men begin to experience a significant decrease in semen volume. Older men can also take longer to conceive a child.
How many eggs do women have in their 30s? There is no one right answer to this question, as certain factors – such as smoking or other personal factors – may mean a woman has fewer eggs than others. The average number of oocytes at the age of 30 would be around 72,000 (12% of maximum pre-birth levels).
A gradual but significant decline begins around age 32. 1 Yes, your odds of conception at 33 are not as good as they were at 28. At around age 37, fertility starts to decline at a much more rapid pace. Research has found that in any given month your chances of getting pregnant at age 30 are about 20%.
For example, a woman at 30 often has around 100,000-150,000 eggs in reserve. By 35, that number is likely around 80,000. Late into the thirties, that number could be 25,000, 10,000, or fewer.
Because women in their late 30s and 40s have a higher percentage of abnormal eggs, it's much more likely that their one egg each month will be abnormal. That's why natural fertility declines with age, and why we see infertility, miscarriage, and genetic disorders more often with women over 35.
Irregular period cycle and difficulty conceiving
If you are facing issues conceiving and have not been able to conceive for a while now, it could be one of the signs of bad egg quality.
The level of AMH in the blood can help doctors estimate the total number of follicles inside the ovaries, and therefore a woman's total egg count. Because AMH levels stay basically stable throughout a cycle, the blood test can be performed at any time.
Your most fertile day, and the day you are most likely to ovulate on, is the last day of egg-white cervical mucus. You can also track your ovulation hormone using at-home ovulation tests (sometimes called an ovulation predictor kit, or OPK).
The study published by the University of St. Andrews and Edinburgh University in Scotland found that women have lost 90 percent of their eggs by the time they are 30 years old, and only have about 3 percent remaining by the time they are 40.
ACOG states that a female's fertility gradually and significantly drops around age 32. They will have around 120,000 eggs, with a 20% chance of conceiving per cycle. ACOG further states that a female will experience a rapid decline by age 37, when egg count drops to around 25,000.
A trained expert checks your sperm count, their shape, movement, and other characteristics. In general, if you have a higher number of normal-shaped sperm, it means you have higher fertility. But there are plenty of exceptions to this. A lot of guys with low sperm counts or abnormal semen are still fertile.
Male fertility generally starts to reduce around age 40 to 45 years when sperm quality decreases. Increasing male age reduces the overall chances of pregnancy and increases time to pregnancy (the number of menstrual cycles it takes to become pregnant) and the risk of miscarriage and fetal death.
What are your chances of getting pregnant every month? Generally, a woman who's trying to get pregnant has between a 15% and 25% chance of doing so each month. Despite those odds, most couples conceive within the first year of trying.
