Explain the anatomy Ovary
Ovarian is a member of reproduction first in women, its shape resembles a grain of almonds or beans, and different size from woman to woman, but at the same Alnroh, ranging size between 3.5 - 5 cm in length and 2.5 cm wide, and 1 - 1.5 cm thicker, and weighs 5 - 10 g.
Before puberty the ovarian surface smooth soft, but after puberty, and repeat the process of ovulation ovarian surface becomes wrinkled because of the scars left behind by the Houselat failed Dograv.
After menopause wither and shrink and bears the size of ovarian
Installation of ovarian
Ovary consists of a very large number of raw egg cells are positioned amid a core composed of connective tissue, and the outer surface covered with a single layer of epithelial cells cubic known as "bacterial coating" Germinal epithelium, and often go away this layer in women after puberty.
The bottom of the crust are fibrous portfolio consists of fibers of the connective tissue, called "ovarian white coat" Theca Albuginea.
Ovarian two consists of two layers:

The bottom of the crust are fibrous portfolio consists of fibers of the connective tissue, called "ovarian white coat" Theca Albuginea.
Ovarian two consists of two layers:
- Pulp
Medulla
A central core is rich in blood vessels, which are located between the muscle connective tissue, which is the biggest part of the ovary, surrounded by white coat- Cortex crust
Thin surface layer, generating ovules, white, contain thousands of vesicles initial primordial follicles, size 0.25 - 1 mm, one composed of egg consists of a single layer of cells beloved, including sophisticated cells secrete hormones.
Cortex is located between bacterial coating consisting of cubic epithelial cells from the outside, and white coat from the inside, which surrounds the pulp.
Each month begins a vesicles initial growth into a pod Dograv Follicle of De Graaft, and cells proliferate granulocytes and secretion called "liquid follicular" that drives Balbaadh initial O O Gonium to one aspect of the bursa, and be on the wall of the egg The Primary area transparent zona pellucida and covered in cells trotted called "corona beam" corona radiate. The inner wall of the pod Dograv padded cells grainy are denser be "membrane granulated" Membrane Granulosa, and evolve cells outside this membrane granulated to form a layer called "inside cover" Theca Interna, the secrete hormones, and cells outside of this inside cover constitute portfolio false called "outer shell "Theca Externa has no secretory function. When ovulation pod splits Dograv mature and explode from the corona beam come out from the egg.
Prior to ovulation completed Meiosis in Sperm The Primary so give polar body first, which bore the cells 23 chromosomes, and the egg initial carrying 23 chromosomes, unite this egg preliminary with sperm also contains the 23 chromosomes, become an egg fertilized and contains the 46 chromosomes, including 23 of the raw egg, and 23 of the sperm.
After a process of ovulation Enkmus pod Dograv, darling cells to Milotna cells Luteal, and turns the inside cover to cover Ojtny Theca Lutein Cells, yellow and shows the body of the hormone secretion process estrogen and progesterone. If we do not succeed egg bears the yellow body and disappears within 10 days, and menstrual bleeding occurs, and turns to the so-called body is a white scar dead.
As if pollination occurs, the body continues to grow yellow and secretion amounts to size 3 cm ², and continue in the secretion of the hormone progesterone until the third month of pregnancy, a time when the placenta takes the role of secretion from the corpus luteum.
Contains ovarian girl newborn about 2 - 3 million egg previews, and at the age of 7 years reduced the number to about 300,000 egg, and at puberty about 5 - 6 thousand egg, cooked them and go out to the fallopian tube and one each month alternately throughout the stage of sexual activity. For a total eggs mature that is excreted when the female about 360 eggs, and when menopause remains in the ovary few hundred eggs mature, and noted that some vesicles Dugrav grow and mature but do not explode rather than leaving it eggs, and thus does not consist yellow body, and here dries liquid follicular, and vesicle is transformed into fibrous mass.

Ovarian
functions
The ovary two main functions:
- Be the eggs have already explained
- Secretion of sex hormones, namely:
A - estrogen (Alaustradiol) Estrogen: daily excretion rate 0.07 mg at the start of the follicular phase, and 0.6 mg immediately prior to ovulation and is working to increase the size of the genitals, and increase sexual arousal (الليبيدو Libido), and this is called the hormone of love and compassion
B - Progesterone Progesterone: average in the blood when the man 0.3 ng / cm ³, and when women 0.9 ng / cm ³ during stage follicular or stage reproduction, either through welcoming Allutinah or glands standing, secretion of ovarian him 20 times goes up an average of blood to 15 ng / cm ³It works to create the lining of the uterus to receive the egg and embryo implantation in the womb, and so-called "pregnancy hormone"
C - androgen
D - Alrulaksin
Changes associated with the process of ovulation in the lining of the uterus = menstrual
Uterus consists of three layers from outside to inside: serous layer, a thick muscle layer, and a layer called mucosa lining of the uterus Endometrium.
Occurs in the lining of the uterus changes the impact of ovarian hormones lead to bleeding from the lining of the uterus called "menstrual", passing the mucous membrane lining of the uterus during the menstrual cycle following phases:
1 - reproduction stage proliferative phase:Starts from the fifth day of the descent of menstrual blood and lasts until the fourteenth day, in the fifth day be membrane lining of the uterus accurate no more than thickness 2 mm, and begin Troyth vessels and thickness increasing, and glands are straight and cells cylindrical high, then take the arrogance and aliasing. This phase tracking the growth of follicles Dograv in ovarian defines "follicular phase"
2 - stage secretion or Albroogesteronih stage secretory or progesterone phaseStretch between day 15 - 28 of menstruation: multiply through thick lining of the uterus, becomes thick 4 to 5 mm, and increase the size of the glands and frequently Tarjha, and swell lining more, and take arterioles spiral emerge and continue to increase in size and clarity, and the volume Algjaj and arterioles and cells in peak in the twenty-eighth day
3 - menstrual phaseIn the absence of fertilization of the egg flaking swollen membrane lining of the uterus, leaving the inner layer intact, and happens is menstrual bleeding, and lasts from the first day until the fifth day
