Can a woman run out of eggs at 30?
Egg numbers change as we age
The monthly cycle described above then continues throughout a woman's life until there are no eggs left. You will have around 27,000 eggs remaining in your late 30s and around 1000 at the onset of menopause.
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.
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.
Intro to assisted fertility. Any successful pregnancy is viable with just one egg. As an increasing number of women delay pregnancy until their 30s and 40s, getting pregnant is increasingly a sociotechnical process.
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.
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 vaginal ultrasound is the best way to accurately assess and count the number of antral—or resting—follicles in each ovary. These sacs contain immature eggs that may potentially develop in the future. Counting the number of follicles is called an antral follicle count (AFC), which is performed via an ultrasound.
Women become less likely to become pregnant and more likely to have miscarriages because egg quality decreases as the number of remaining eggs dwindle in number. These changes are most noted as she reaches her mid-to-late 30s. Therefore, a woman's age is the most accurate test of egg quality.
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 becomes more rapid once you reach your mid-30s. By 45, fertility has declined so much that getting pregnant naturally is unlikely for most women.
A woman is born with all her eggs. Once she starts her periods, 1 egg develops and is released during each menstrual cycle.

You can't make a baby with two moms by simply fusing two eggs or adding one egg's DNA to another's. Even though the resulting embryo would have the usual 46 chromosomes, this wouldn't work.
Ages 31 to 35
You still have a lot of high-quality eggs to offer, but your odds will start to decline steadily at this age. Your fecundity rate decreases gradually until age 32. At 37, it drops dramatically. In your 30s, you're about half as fertile as you are in your early 20s.
If your menstrual cycle lasts 28 days and your period arrives like clockwork, it's likely that you'll ovulate on day 14. That's halfway through your cycle. Your fertile window begins on day 10. You're more likely to get pregnant if you have sex at least every other day between days 10 and 14 of a 28-day cycle.
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.
- Difficulties getting pregnant.
- Heavy menstrual flow.
- General changes to menstrual cycles, like a late or absent menstruation or menstrual cycles that are shorter than usual.
While age is the main factor determining egg count, there are a variety of factors that can potentially contribute to a diminished ovarian reserve, including: Genetic mutations that affect ovarian function. Chemotherapy or radiation therapy. Surgery that involves removing part or all of each ovary.
Raspberries, blueberries, and strawberries all contain natural antioxidants and anti-inflammatory phytonutrients, two components that greatly improve fertility for both men and women. This study showed that women with high fruit intakes had a significantly reduced chance of infertility.
How many egg do I have left?
If you'd like to find out how many eggs you have left, you can have an anti-mullerian hormone (AMH) test. This is a simple blood test that's used to check how many potential egg cells you have left (ovarian reserve). If your ovarian reserve is high, you might have a better chance of getting pregnant.

Menopause. Natural cessation of ovarian function and menstruation. It can occur between the ages of 42 and 56 but usually occurs around the age of 51, when the ovaries stop producing eggs and estrogen levels decline.
After the early 30s, both the quality and quantity of eggs begin to decline, resulting in a decline of fertility potential, with the most significant declines occurring in the mid 30s and early 40s. The decline in both egg quantity and quality may manifest in a longer time to conception.
The number of eggs decreases as women get older. At birth, most girls have about 2 million eggs, at adolescence that number has gone down to about 400, 000, at age 37 there remain about 25,000. By age 51 when women have their menopause they have about 1000 immature eggs but these are not fertile.
