When do ultrasound to determine ovulation
Duration of the menstrual cycle is generally 23-35 days, and the counting from the first day of onset of menses. If the duration is greater than or less, then it is a sign of failure of the production of hormones or various disorders fertility in women.
The phases of the female menstrual cycle:
- Menstrual - lasts 3-6 days, during which the endometrium, which is in the uterine cavity, and leaves the body is torn away together with blood.
- Follicular - duration of 2 weeks with a deviation of 1-2 days in each direction. During this period, the ovaries produce follicle-stimulating hormone, which affects the maturation of the egg.
- Ovulation - lasts about 3 days, during which the body is allocated a special luteinizing hormone releasing an egg from the follicle.
- Luteal - lasts 6-12 days, but sometimes it reaches a length of 16 days. During this period, the body produces progesterone, which prepares the uterus for fastening the egg.
If conception occurs, progesterone production decreases and the endometrium leaves the uterus during menstruation, which is the beginning of a new cycle.
In the event of failure of one or more is not the menstrual cycle, ovulation phase, which means that pregnancy does not occur. The main cause of female infertility is a long absence of release of the egg from the ovary.
The study, which allows you to determine ovulation by means of ultrasonic waves, called follikulometriey. During the ultrasound monitor the development of the dominant follicle in the ovary.
This study is conducted several times, so that the doctor can fully trace the process of oocyte maturation. Begin it in the middle of the cycle - before the expected date of ovulation. All subsequent procedures are performed at intervals of 2-3 days, which allows for monitoring of ovarian.
When carrying out the second procedure confirmed the presence of the dominant follicle dimensions of about 20 mm, and contained the corpus luteum in the ovary. Data on ultrasound ovulation symptoms indicate the approach of the process.
The third ultrasound examination is carried out after 2-8 days. If the follicle in the ovary is absent, and in the pelvis may notice fluid accumulation, it speaks of the successful completion of ovulation. To confirm the doctor may prescribe a blood test for women progesterone levels, which at times increases ovulation.
In the case where the egg did not come out of the follicle ultrasound monitoring may be continued until the onset of menstruation. At irregular menstruation first ultrasound examination performed 4-5 days after the end of menstruation.
signs of ovulation
Learn about what is approaching the process of allocating the egg from the follicle, it is possible for the following signs of ovulation, in addition to the US:
- Vaginal discharge - heavy and viscous.
- Aching pain in the lower abdomen - the reason for this phenomenon is becoming an egg promotion of the fallopian tubes.
- Strong sexual desire - at ovulation, an increased level of progesterone, which is produced by the corpus luteum. He and causes anxiety.
- The increase in basal body temperature, which is measured immediately after awakening. If the value is 37 ° C, it means that the egg is the beginning of their movement. This feature is considered one of the most informative.
Since the most favorable time to fertilize is just ovulating, all attempts to conceive a child should activate for 1-2 days before it started, and 24 hours after completion.
Despite the fact that the most reliable way to detect ovulation is considered to ultrasound, and other techniques are used. For example, very popular Ovulation Test.

How to calculate ovulation for your menstrual cycle
In addition to ultrasound, to determine ovulation may be several other ways.
Measurement of basal body temperature
To obtain reliable results measurement of basal body temperature you need every morning to introduce the thermometer rectally and wait 8-10 minutes. The data obtained should be recorded every day. If after the menstruation value averages 36,6-36,9 ° C, then it before ovulation decreases slightly, and then increases to 37,0-37,3 ° C, remaining at that level up to the beginning of the next monthly.
The results obtained in this manner are distorted for the following reasons:
- inflammatory processes in the body;
- colds;
- hormones;
- consumption of alcoholic beverages;
- defective sleep (less than 6 hours);
- intimacy for 1-6 hours before the test for ovulation.
Identification of the luteinizing hormone
This rapid test is performed in a period when there is usually an egg maturation. It must carry out according to the instructions, 1-2 times a day.
A positive result, in which the strip to be two bright bands, means that the next day is the most favorable for conception.
The calendar method
In determining the favorable time for conception in this way need a calendar, as well as knowledge of the woman's menstrual cycle. This method can only be used with regular menstrual cycle. Calculation of the menstrual cycle are produced in the following manner:
- release date of the beginning of the month for the past 3-5 months;
- calculate the length of the cycle, which represents a period from the beginning of menstruation to the next;
- 14 taken away from the total duration of the cycle. The result will be determined by the day, which will have to start ovulation - it should be noted on the calendar. For successful conception intimacy is recommended for 1-2 days before and after the follicle maturation.
The latter method is quite simple, its main disadvantage is low accuracy, as in the current cycle time is influenced by various factors - climate, illness, stress.
If a woman's menstrual cycle is stable, then it is not necessary to undergo monthly tests to determine ovulation. It is enough to make observations within 2-3 months, and in the future based on the results obtained. Due to the period of the plan will be able to accelerate the onset of a wanted pregnancy.
