How to detect ovulation? Painful short-term feeling in the abdomen can predict ovulation. Also you can recognize it by increased mucous discharge from the vagina, and reduced rectal (basal) temperature, which rises again the next day after the ovulation day. More about this may indicate an increased level of progesterone in blood plasma and other Failure of the ovulation cycle can occur due to dysfunction of the hypothalamic – pituitary-ovarian system. It is possible inflammation of the genitals, dysfunction of the adrenal or thyroid, chronic diseases, tumors of the pituitary and hypothalamus, as well as under stress. If no ovulation, when a woman to be in the reproductive age (this is called anovulation), it is expressed disturbances of the menstrual cycle when the discharge continue for 1 – 2 days (oligomenorrhea), amenorrhea, dysfunctional uterine bleeding. If ovulation does not occur at all in women, she is diagnosed with infertility. To restore ovulation when the intervention of skilled professionals, establishing the true cause of the violations and eliminating them using the correct medicines and treatments.
Ovulation and contraception
Quite often during ovulation, women experience sexual attraction, or even excitement. Young couples who have sexual activity is improved, can’t one hundred percent to rely on the contraceptive effect of abstinence from sexual acts during ovulation. It should also be noted that the bright emotional outbursts or nervous disorders can cause additional ovulation. This is more likely if You were fickle, casual intercourse. In such cases, for one menstrual cycle can ripen two eggs instead of one. Remember this when you decide what method of contraception to stop.
Physiology of ovulation cycle
When healthy girls aged 11 to 15 years begins the menstrual cycle, it is possible consciously to talk about putting her body to reproduce. But, at the same time, there are a number of issues associated with menstruation. For example, how to calculate the cycle, why not Your period went on time or why I cannot get pregnant. All it constantly gnaws at the woman, she is always waiting for what will happen next and not fully aware of what is going on with it really. These doubts haunt almost all my life. The duration of the menstrual period and cycle.
Ideally, menstrual flow lasts for 3 – 5 days and repeated every 28 days. But everyone is different. There are women whose cycle is 19 days or less. And there, on the contrary, longer cycles that can last from 35 to 45 days. And it will not be a deviation, it’s just a characteristic of a certain female body. Themselves spotting can also go from three to seven days, and it also should not You feel strongly about, it is quite normal. But if You delay, which lasts for more than two months (optometry), or more than six months (amenorrhea), we think, why it happens, and be sure to consult your gynecologist.
Duration of the menstrual cycle
Let’s take a closer look, what is the menstrual cycle. This is a natural physiological process that accompanies a woman until the age of 45 – 55 years. For its regulation meet the so-called sexual centers, which are located in the hypothalamus. During a cycle is the series of transformations that are most clearly tracked in the uterus and ovaries. The follicles of the ovaries in conjunction with the adrenal cortex and testes produce a number of hormones under the influence of which grows and develops primary follicle, placing yourself in the egg. When the follicle is fully Matures, it breaks, giving the egg freedom of movement. She, in turn, with follicular fluid into the uterine (fallopian) tube through the abdominal cavity. The time when the follicle bursts and releases suitable for fertilization of the egg is called ovulation. If your menstrual cycle is the standard 28 days, it is between about 13 and 15 in the afternoon.
Yellow body, estrogen, progesterone
Instead of the ruptured follicle appears yellow body. Such morphological changes in the ovary are invariably accompanied by the secretion of sex steroid hormones, namely estrogen and progesterone. When this follicle produces estrogen, and a yellow body – progesterone.
Most the maximum release of estrogen may be twice per cycle: ovulation and peak activity of the yellow body. For example, the usual amount of estrogen in the female body for about 10 µg/l In the period of ovulation and its quantity considerably increased and is already 50 µg/l During pregnancy, especially during the last period, these figures are even higher – about 70 to 80 µg/L. This is due to the rapid increase in the biosynthesis of estrogen in the placenta.
What do they need? Estrogen together with progesterone help fertilized egg to penetrate into the uterus. In addition, they maintained pregnancy. Also, they’re facilitate childbirth. These hormones are extremely important for the female body. Their contribution is enormous: they participate in the regulation of different biochemical processes play an important role in carbohydrate metabolism, help distribute lipids, increase the synthesis of amino acids, nucleic acids and proteins. In addition, they help the calcium to secede in the bone, don’t give excreted from the body sodium, potassium, phosphorus and water. Estrogens increase the concentration of these elements in the blood, and electrolytes (urine, saliva, tears, nasal secretions).
Controls the secretion of estrogen anterior pituitary and its gonadotrophin hormones, namely, folliculosebaceous (FSH) and luteinizing (LH).
In the first stage of the menstrual cycle, which is also called folliculinum, under the influence of estrogen, the regeneration of the uterus. Restores and increases mucous membrane – the endometrium grow gland, being extended in length and saivas. Thickening of the mucous membrane of the uterus to become greater in 4 – 5 times. In addition, it becomes abundant secretion of mucous secretion in glands cervix to dilate the cervical canal, allowing the sperm to easily pass the egg. Inside dairy paths female breast epithelium proliferates.
Upon the occurrence of so-called luteal (comes from the Latin word luteus – yellow), or the second phase in the body decreases the activity of metabolic processes. This occurs under the influence of progesterone. The mucous membrane of the womb is no longer grows, it becomes looseness and swelling. Her Breasts formed a secret that create the most comfortable conditions for attachment of a fertilized egg to the mucosa and development of the fetus. Mucus stops to stand out from the glands, blocked the channel. At the same time, a woman’s Breasts are formed alveoli. They arise from overgrown mammary epithelium moves. These alveoli are absolutely ready for production and secretion of milk. If desired the pregnancy does not occur, then yellow body dies. Is the rejection of the functional layer of the endometrium and menstrual cycle begins. These spotting can go from three to seven days. Blood when it goes from 40 to 150 grams.
Timing of ovulation
It should be noted that the timing of ovulation is not the same for all women. Sometimes temporary settings are dramatically different. Even the same woman can change the terms at different periods. There are also women who have irregular menstrual-cycle – normal life. Are the cycles may be different in duration. If your menstrual cycle is very short, ovulation may occur at the end of this period. But most of all, still ovulation is a regular phenomenon.
It happens that ovulation does not occur for a number of reasons. In this case, the layer of the endometrium in the uterus comes out when the menstrual discharge. During fertilization of an egg by a sperm, it is possible to observe a certain vibration of the egg cytoplasm, similar to the vibrations during orgasm. If the sperm has penetrated, it means that the egg is completely ready for reproduction. Sperm leaves only the core, which contains 23 chromosomes, half set of standard cells. The egg nucleus also contains 23 chromosomes. When they collide, their shells dissolve, and they merge into one, forming 46 chromosomes and separating into pairs. 22 chromosome sperm from 23 completely repeat the chromosomes of the egg. They all carry information about the physical characteristics of the future person, not only determine its gender. But in the remaining pair of chromosomes from the egg is always X, and from sperm – either the X or Y chromosome. If they make a couple of XX, then you will wear the girl, as if HOO boy.
