What you need to know about the ovaries

Most likely, you have a general idea of ​​what is needed ovaries: they contain egg until such time as they will not have to ripen. After ovulation, the ovaries release a cell in the fallopian tube, so that she has been fertilized. If this does not occur, the egg passes through the uterus and removed together with the shell, which was built in the case of fertilization.

In fact, the ovaries do much more work than you think, and they are influenced by many factors. We collected a few little-known facts that are necessary to know all the girls about their reproductive system.

The ovaries produce many hormones

This body is responsible for producing the majority of hormones in your body: progesterone, testosterone, inhibin, relaxin - and even for three types of estrogen: estradiol, estrone, and estriol. Each of them performs a role: some help the body grow, others provide libido and fertility, and others are preparing your body for childbirth.

All egg formed more than once in the life of

For years, doctors have supported the view that women are born with all the eggs that they will ever be - roughly about 2 million. By puberty this number decreased to 400 thousand, and ripen during ovulation will not be more than 500. But research in 2012 showed that the ovaries can produce more eggs than was assumed. Yes, as long as the study did not receive full confirmation in humans, and tests were carried out on mice, but now it can be assumed that most likely, the common fact of a woman's body will be just a myth.

They change their size

The ovaries do not remain the same size throughout your life. According to the visual model, published in PLoS One publication in 2013, the ovarian volume by 69% depends on your age. When you have a child, he was somewhere 0, 7 ml. Peak ovarian volume - 7, 7 ml - occurs in the area 20, then this size will gradually decrease. At the time of menopause, they can be as small as about 2, 8 ml. The ovaries can change the size and other reasons, most often associated with serious health problems. changes in volume may indicate cancer, endocrine disorders, polycystic and other important issues, so this is another important reason to visit the gynecologist.

They are influenced by stress

If you are very disturbed, it can also affect your ovaries. Hormones that regulate stress, such as cortisol, disrupt the transmission of signals between the brain and the reproductive system. This can lead to the fact that you have lost ovulation, and later it will cause even more health problems.

Some may feel the ovary during ovulation,

A very small percentage of women are able to feel how the egg is released. This occurs about 14 days before the onset of menstruation, when the follicle in the ovary ruptures and releases an egg matured. If at this moment you feel a cramp or a sudden sharp pain, most likely, this is ovulation.

No one knows why a particular cell matures in ovulation

Each month after menstruation ends, the ovaries begin to grow follicles that may mature. Released only one egg - sometimes scientists call it the "queen." But until now, absolutely not known exactly why it stands out in the ovulation and it is better than the others.

The right ovary releases an egg better than

Absolutely no one knows why, but the left and right sides of the reproductive system works differently. But numerous observations we can say that the right-ovulation is more common than left-handed. Laws of no and where ovulation occurs the last time - does not matter.

The reception of contraceptives can reduce the risk of developing ovarian cancer

According to a study published in the journal "Obstetrics and Gynecology" in 2013, women who take the pill for 10 years or more, they saw a huge decline - 50% - diseases of ovarian cancer. What is no less important: the effect can last for 15 years after the discontinuation of the pill.

A quarter of the world's women living with ovarian cysts

According to the US National Institutes of Health, an ovarian cyst is usually defined as any ovarian follicles, which grew by about two centimeters. You can not call it a reason to worry: according to a study in 2018, published in JAMA Internal Medicine, in a group of 72 000 people to the ovaries, which did a pelvic ultrasound, about 23% of those aged 50 years and older and 13% of those who are over 50, have had ovarian cysts. Moreover, only one of those members who have a simple ovarian cyst was established, developed ovarian cancer. Most cysts disappear without treatment, but you can not even know that you have it. However, it is still not a reason to miss his annual medical examination.
