Egg-citing Pictures! Egg Released During 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.

This knowledge may be important to consider for family planning. Normal Ovarian Function The ovaries are two small organs, about the size of your thumb, that are located in the female pelvis. 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.

The ovary can be seen here at the end of the fallopian tube. At around this time of the menstrual cycle, a follicle at the surface of the ovary releases an egg, which is swept down the tube by clearly visible fingerlike projections called fimbriae. Typically ovulation occurs around day 14 but it can occur earlier or later. Ovulation is when an egg is released from your ovaries sometimes two eggs are released. LH rises thanks to estrogen output from the growing follicles see This is Day 12 of your Menstrual Cycle , and it is this rise that triggers the events that now take place in the follicle. LH makes the egg inside the follicle become fully mature, ready for release and fertilization. This is the point at which the egg reduces its number of chromosomes see How genes are passed on from 46 to
