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.

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

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.
