From this time, no new eggs are produced. At birth, there are approximately 1 million eggs; and by the time of puberty, only about 300,000 remain. Of these, only 300 to 400 will be ovulated during a woman's reproductive lifetime.

For women who have a 28 to 32-day menstrual cycles, ovulation can take place between days 11 through 21, but it will only occur on ONE of these days. Remember, this is just an average of days that ovulation could take place—every woman's cycle is different.

Ovulation can be calculated by starting with the first day of the last menstrual period (LMP) or by calculating 12-16 days from the next expected period. Most women ovulate anywhere between Day 11 – Day 21 of their cycle, counting from the first day of the LMP.

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.

Most women ovulate anywhere between Day 11 – Day 21 of their cycle, counting from the first day of their last period. This is your “fertile time” and when sexual intercourse has the best chance of producing pregnancy. Ovulation can occur at any point during this window and may occur on a different day each month.

But to create a highly generalized idea — women with normal ovarian reserve under the age of 40 should be able to attain a range of 10-20 eggs in a cycle. You'll actually be able to use a calculator to estimate your chance of a successful pregnancy with a certain number of eggs at any given age.

Ovulation is a monthly occurrence for women of childbearing age. It usually takes place around day 14 of a 28-day menstrual cycle. During this process, an egg is released from one of your ovaries and travels from your fallopian tube to your uterus. The release of an egg isn't a spontaneous occurrence.

As women are only born with a finite number of follicles (eggs), a decline in fertility is natural as there is a decrease in the number of eggs with time. Therefore, whilst a 40 year old woman still has around 10,000 eggs, this is just 3% of the original 300,000 present at the onset of puberty.

As you can see, for most days within the fertile window, a woman in her late 30s has a nearly 25% chance of conceiving. But her overall chances are still considerably lower than those of a woman in her early 20s, mainly because she has lower chances of conceiving on her most fertile day.

Many women typically ovulate around 12 to 14 days after the first day of their last period, but some have a naturally short cycle. They may ovulate as soon as six days or so after the first day of their last period.

Results from a study even found that 82% of 35-39 year-old women are likely to conceive with a year if they are having sex at least twice a week. However, many women will also struggle to conceive at this age owing to their decreasing chances of getting pregnant, and will so seek some fertility assistance.

By age 40, the average woman has roughly a 5% chance of getting pregnant per cycle. After age 45, gynecologists describe getting pregnant naturally as “unlikely for most women.”

If you have a 28-day cycle, your ovary likely releases an egg 14 days after the first day of your last period, although the timing can vary. If your cycles last 35 days or longer, you probably ovulate at day 21 or later.

For women 30 to 34, their chances of getting pregnant within 1 year is approximately 63 percent. For women ages 35 to 39, the chances of conception within 1 year declines to 52 percent. This rate continues to decline in a woman's 40s, until she reaches menopause, typically between ages 48 and 55.
