Female Eggs are important for reproduction in humans. The female sex cells of the body, called oocytes, develop within the ovaries. The ovaries also produce hormones that regulate the reproductive system and control how much estrogen there is in your body. When an egg is released from one of your ovaries, it travels down one of two fallopian tubes into your uterus (womb).
Eggs are made in the ovaries.
The ovaries are small, yellowish-brown organs located on either side of your uterus. The largest organ in your body, they are about the size of a walnut and contain thousands of follicles that produce eggs.
Once an egg is released from one of these follicles it travels down a fallopian tube to your uterus where it can be fertilized by sperm and developed into an embryo.
Ovaries and eggs are formed when a baby girl is in the womb.
The ovaries and eggs are formed in the womb before birth.
The eggs start to form in the first trimester of pregnancy. In fact, they start to develop at about the same time as your baby’s brain, heart and other organs.
You won’t know that you’re pregnant until you’re about three months along—that’s when your baby has grown enough for you to feel its movements or hear its heartbeat with an ultrasound machine (more commonly known as a sonogram).
A woman has all the eggs she will ever have when she is born.
The ovaries produce eggs, or oocytes, before birth. A newborn girl is born with all the egg cells she will ever have — about 1 million of them. By puberty, she has only 400,000 left and by age 25 she has 300,000. The rest are lost through menstrual bleeding or are absorbed into her body when they’re not needed to make an embryo.
When an egg matures in the ovary and then becomes available for fertilisation (ovulation), it’s called a zygote. Zygotes grow into embryos that implant into the uterus wall for further development if fertilised by sperm during intercourse; otherwise they die off because of lack of nutrients and oxygen after a few days inside their mother’s body
The number of eggs a woman has decreases as she gets older.

Women are born with all of their eggs, but they lose them over time. The ovaries are where female eggs are formed and stored, so when you get older, your ovaries start to produce fewer new eggs because they have already run out. That’s why it’s important to have children while you still can: if you wait too long, it may be too late!
In order for an egg to develop and mature, it must be fertilized by a sperm cell (from a male).
The female egg is the largest cell in humans. It’s about 0.1 mm in diameter, and it’s only visible with a microscope. The sperm cells are much smaller than eggs, with some being as small as 0.0003 mm (0.3 micrometers).
The egg grows inside a follicle, which is a sac-like structure that holds one or more eggs in place before they’re released from the ovary during ovulation (the release of an egg from one of the ovaries).
There are only about 200–300 maturing eggs at any given time throughout a woman’s lifetime; however, once she reaches puberty and starts to menstruate (have her period), there will be additional growth spurts each month as part of her menstrual cycle until menopause begins at age 51 (or 52 if she has had children).
In women, only one egg matures per cycle and is released from the ovary about 14 days after the start of her menstrual cycle (the first day of her period).
In women, only one egg matures per cycle and is released from the ovary about 14 days after the start of her menstrual cycle (the first day of her period). This egg moves down from the ovary into a fallopian tube. If it isn’t fertilized by sperm, it passes out of a woman’s body each month during menstruation.
Each month, an egg develops from a specific area in each ovary called the follicle.

The follicles contain undeveloped eggs (ova) that have matured in the ovaries over time. As you get older, some of your eggs get released without fertilization and are lost. One of these egg cells will mature each month and release an egg through the fallopian tubes into your uterus.
It takes about 24 hours for an egg to mature once it’s released from the ovary. If it isn’t fertilized during this time, menstruation starts soon afterward (about 14 days after ovulation).
After being released from the ovaries, an egg moves through the fallopian tubes to meet with sperm. If fertilized, it will continue down into the uterus and begin developing into a fetus (if you’re pregnant).
If no sperm are present in the fallopian tubes when an egg is released, then there’s no chance of getting pregnant. The lining of your uterus also degenerates if you don’t get pregnant so that it can be shed during your period.
Females have all their eggs by birth and lose them over time.
As you know, females have all their eggs by birth, unlike males. This means that in their entire lives, women will never produce a new egg. They don’t replace any of the ones they’ve lost over time.
Because of this, female fertility decreases with age and eventually ends when no more eggs remain—something not true for men. Men can continue to make sperm throughout life; however, they do need to produce it regularly in order for it to stay healthy and viable.
The ovaries contain two main types of cells: oocytes (immature eggs) and follicles (the structures that protect oocytes). Once an oocyte is released from a follicle during ovulation (and before fertilization), it cannot be replaced if lost due to damage or aging—meaning female fertility declines as we age because there are fewer and fewer available eggs within our bodies over time.*
Conclusion
Women have all the eggs they will ever have by birth. As a woman gets older, her ovaries become less able to produce viable eggs, which means that the risk for infertility increases with age. This is why it’s important for women who want to get pregnant later in life to seek help from fertility experts or doctors before starting any treatment options like IVF.”
