When does a womans egg get released
When a woman ovulates, she releases a mature egg from one ovary or two eggs if she is having twins. Sperm needs to reach the egg before this time lapses. An egg is most likely to be fertilised to conceive a baby if the sperm are already present, waiting in the fallopian tube, so they reach the egg soon after it is released. If your menstrual cycle is regular, then you may be able to predict when you ovulate by counting the days of your cycle.SEE VIDEO BY TOPIC: Ovulation

What Is Ovulation?
The ovaries are filled with follicles. Follicles are fluid-filled structures in which the oocyte also called egg grows to maturity. Current knowledge indicates that females are born with their entire lifetime supply of gametes. Females are not capable of making new eggs, and in fact, there is a continuous decline in the total number of eggs each month. Over the next years of a female's reproductive life, the entire egg supply will be depleted.
Although no one can know with absolute certainty the number of eggs remaining within the ovaries at any given time, most women begin to experience a significant decrease in fertility the ability to conceive a child around the age of At the time of menopause, virtually no eggs remain. The large supplies of eggs within each ovary are immature, or primordial, and must undergo growth and maturation each month. The eggs are stored within follicles in the ovary. Within a woman's lifespan, large numbers of follicles and oocytes will be recruited to begin the growth and maturation process.
The large majority, however, will not reach full maturity. Most will die off in a process called atresia. Thus, only about of these eggs will mature over a women's life span.
The maturation of eggs typically takes about 14 days and can be divided into 2 distinct periods. During the initial period, many eggs, as many as , begin to develop and mature. The second phase of development requires gonadal hormone stimulation to stimulate further development. However, even though hundreds of eggs have begun to mature, most often only one egg will become dominant during each menstrual cycle, and reach its' fully mature state, capable of ovulation and fertilization.
Pre-pubertal girls do not produce the gonadal hormones that are necessary for the second phase of development, so the many eggs that started to mature will simply wither away.
The large number of eggs that are used each month account for the steady decline in the female's total egg pool that occurs from birth to menopause. In post-pubertal females, the dominant egg continues to develop, relying on hormones for growth and stimulation. When the egg becomes fully mature, the follicle surrounding the egg bursts, and releases a mature egg which travels through the fallopian tube toward the uterus. The egg is capable of being fertilized for a short period, about 48 hours.
If the egg is not fertilized during this time, it will die, and in another week or so, a new cycle of egg maturation will begin. This cyclic process of development continues through out a female's life until most or all of the eggs are depleted. This is the period of life known as menopause.
This occurs sometime in the 4th or 5th decade of life, with the average age in the US being Depletion of the egg pool anytime prior to age 40 is referred to as premature ovarian failure. Any female who receives treatment with drugs that damage the ovarian follicles is at risk to develop premature ovarian failure--even many years after the treatment has ended. The majority of young girls treated with chemotherapy will retain fertility initially, but may be at risk to develop premature ovarian failure.

They are attached to the uterus, one on each side, near the opening of the fallopian tube. The ovaries contain the female gamete cell, called the oocyte.
How Pregnancy Happens
Every month, the reproductive organs in a healthy woman prepare for pregnancy. After ovulation the egg lives for 12 to 24 hours and must be fertilised in that time if a woman is to become pregnant. The burst of oestrogen just before ovulation also works inside the neck of the uterus the cervix to make protein-rich clear jelly that covers the top of the vagina during sex. This makes the vagina acidic which prevents thrush and other infections.
When a young woman reaches puberty, she starts to ovulate. This is when a mature egg or ovum is released from one of the ovaries. The ovaries are the two female reproductive organs found in the pelvis. The placenta then develops.

Ovulation and conception
Part of the ovary called the ovarian follicle discharges an egg. The egg is also known as an ovum, oocyte, or female gamete. It is only released on reaching maturity. After release, the egg travels down the fallopian tube, where it may be met by a sperm and become fertilized. Ovulation and hormonal release during the menstrual cycle are controlled by a part of the brain called the hypothalamus.
Ovulation is a phase in the menstrual cycle. It occurs at about day 14 of a day menstrual cycle. However, during days 10 to 14, only one of the developing follicles forms a fully mature egg. At about day 14 in the menstrual cycle, a sudden surge in luteinizing hormone causes the ovary to release its egg.
The ovaries are filled with follicles. Follicles are fluid-filled structures in which the oocyte also called egg grows to maturity. Current knowledge indicates that females are born with their entire lifetime supply of gametes.
Back to Periods. The length of the menstrual cycle varies from woman to woman, but the average is to have periods every 28 days. Regular cycles that are longer or shorter than this, from 21 to 40 days, are normal. Between the ages of 12 and 52, a woman will have around periods, or fewer if she has any pregnancies. To understand the menstrual cycle, it helps to know about the reproductive organs inside a woman's body. These are:.
5 Facts About the Female Egg Cell
Ovulation is the release of an egg from one of a woman's ovaries. After the egg is released, it travels down the fallopian tube, where fertilization by a sperm cell may occur. Ovulation typically lasts one day and occurs in the middle of a woman's menstrual cycle, about two weeks before she expects to get her period. But the timing of the process varies for each woman, and it may even vary from month to month. If a woman is hoping to become pregnant, she will want to keep track of when she may be ovulating. Knowing when a woman is ovulating each month is helpful because she is the most fertile — or able to become pregnant —around the time of ovulation. A couple will be more likely to conceive if they have sex a day or two before a woman ovulates and the day of ovulation, according to the March of Dimes.
Everything you need to know about ovulation
When trying to become pregnant, many couples plan intercourse between days 11 to 14 of the woman's day cycle. This is when ovulation occurs. However, it is hard to know exactly when ovulation will happen. Health care providers recommend that couples who are trying to have a baby have sex between days 7 and 20 of a woman's menstrual cycle.

Кто-то записал его, и я подумал, что это гостиница.
Может быть, американка? - предположил. - Не думаю, - сказала Росио. - На ней была майка с британским флагом. Беккер рассеянно кивнул: - Хорошо. Бело-красно-синие волосы, майка, серьга с черепом в ухе.
Жертва ощутила прикосновение смерти, и началась совершенно иная игра. Беккер мчался, не видя ничего вокруг, постоянно сворачивал, избегая прямых участков. Шаги неумолимо приближались. В голове у него не было ни единой мысли - полная пустота.
Он не знал ни где он находится, ни кто его преследует и мчался, подгоняемый инстинктом самосохранения. Он не чувствовал никакой боли - один лишь страх.
