help identify the most successful days for conception capable Ovulation Test.It helps not only to determine the optimal day for conception, but also to calculate ovulation calendar.Subject to all rules of the test in 90% of healthy women can detect ovulation date.
What is ovulation
Ovulation - this way a mature egg from the main (dominant follicle).Normally ovulation occurs approximately in the middle of the cycle (e.g., twenty-eight day cycle at ovulation is the fourteenth day).However, one should consider not only the length of the menstrual cycle (with a longer ovulation is late and, on the contrary, short-cycle earlier), but also other circumstances which may affect the release of an egg from the ovary (stress, infectious diseases, climate change and more).That is, ovulation may not occur, or occur sooner or later.
Ovulation occurs under the influence of hormones.Estrogens cause the maturation of follicles in the ovary, the middle of the cycle takes a massive release of luteinizing hormone, which is under the influence of the dominant follicle ruptures and releases an egg ready to be fertilized.To the conception occurred, the egg needs to get into the fallopian tube, where it will meet the sperm.That is why the date of ovulation is considered the most favorable for conception.
But it is necessary to take into account the fact that the lifespan of the egg only 24 hours (maximum of 48), and sperm about seven days.
Often a woman alone can determine ovulation has occurred.At this time there are nagging pain in one or both ovaries, the small spotting and vaginal mucus becomes viscous and resembles raw egg white, enhanced libido.
It is also important to remember that regular ovulation rate may change after an abortion for three months postpartum, within twelve months, and after forty years, when depleted ovarian function.

Anovulation caused by a failure in the hypothalamic-pituitary-ovarian system.The reasons for such violations may include: inflammatory diseases of the genital organs (especially the uterus and appendages), pathology of the adrenal cortex, various systemic diseases (eg, diabetes mellitus), tumors of the pituitary gland and the hypothalamus, increased intracranial pressure, stress.
characteristic clinical signs of anovulation in the reproductive years is the menstrual cycle by type of oligomenorrhea (rare and scanty menstruation), amenorrhea (absence of menstruation), uterine bleeding.
to treat anovulation as a cause of infertility, use a variety of hormones (birth control pills to restore menstruation, ovulation-stimulating drugs).In severe cases, a woman prescribed IVF (in vitro fertilization).

first way - this compilation ovulation calendar at home.For this it is necessary to measure the basal temperature for at least three months.Basal temperature - a temperature, which is measured in the rectum, vagina or oral cavity.Considered the most accurate results when measuring basal body temperature in the rectum.It is necessary to measure the temperature of the morning, at the same time, after a continuous nocturnal sleep Dreams: how to understand our dreams at least six hours and the same thermometer.Measuring is necessary for at least ten minutes, and data entered into the schedule of basal temperature (horizontal marks the day of the menstrual cycle days of the menstrual cycle: Four phases , and vertical temperature readings, beginning and ending with 36,2S 37,4-37,6S).Normally, in the first phase of the menstrual cycle, the temperature is below 37 degrees.Before ovulation, it is reduced, and the day of ovulation rises above 37C.
In addition, the calendar should be celebrated and their personal feelings that accompany ovulation (spotting, change in vaginal discharge, discomfort or pain in the abdomen).No need to measure the basal temperature during the menstrual period.
This calendar will help to determine the date of ovulation and its absence for any reason.
second method for determining ovulation - is online calendars.Currently, various sites have programs to help you calculate the day of ovulation How to calculate ovulation date: choose from five methods .Suffice it to add your details: length of the menstrual cycle and menstruation, the first day of the last month and the first day of expected menstruation.Women who have irregular menstrual cycles, do not worry.Suffice it to lay down the length of menstrual cycles for six months and divide by six.The result will be an average cycle time.
how to determine ovulation doctor
There are two ways to determine the health of ovulation.These include:
Ultrasonography is considered the most accurate method of determining the ensuing ovulation.For this, about the end of month, on the seventh day of the menstrual cycle obstetrician gynecologist appoints pelvic ultrasound using a vaginal probe.Ultrasound is repeated every two - three days, and ultrasound monitoring to follow the growth and development of follicles.In addition, determine the thickness of the lining of the uterus growing.Based on all the data you can find out the date of ovulation.
- Determining the level of luteinizing hormone in the body
On this principle is based on the ovulation test work.The level of the hormone is determined on a daily basis for a few specific days.Effective methods for the determination of luteinizing hormone in the blood are: RIA (radioimmunoassay) and other non-radioactive methods.
How does the ovulation test
operating principle of the ovulation test is the reaction of it to the level of luteinizing hormone in the body.As indicated above, just before ovulation increases production of luteinizing hormone, which occurs under the action of the main gap and yield mature follicle egg 'float freely ".That is the test for determining ovulation based on the peak (maximum) level of luteinizing hormone, therefore, a positive ovulation test but will mean that the release of an egg has to happen in the next twenty-four hours, and the sexual act is necessary to make in the next thirty-six hours, bearing in mindthat the life expectancy of the egg just twenty-four hours.
When doing tests for ovulation
To properly calculate the days when you need to determine ovulation, you should first determine the length of the menstrual cycle.Naturally, there are few women who begin menstruating as a clock to the day.The majority of the menstrual cycle varies One - five days each month.To calculate the duration of the cycle, add up the length of the cycle in the last three months and divide by three.For example:
menstrual cycle was 24 days, 21 days later and finally 22 days.Fold (24 + 21 + 22) 3 = 22 days.Then subtract 22 days, 17 days before the start of the upcoming menstruation and get the 5th day of the menstrual cycle.Accordingly, it is the fifth day should begin to conduct the test.
