How long is ovulation
The duration of ovulation, from a few seconds to several minutes. But you need to know that there's ovulatory period in which fertilization is possible. For every woman it is individual.
Follicle – formation of round, pear-shaped or oval, in which the egg develops.
The process of follicle maturation lasts 16-32 hours. After ovulation the egg only lives between 12 hours to 2 days, and retains the ability to fertilize. This period is called ovulation. This period – a few days before ovulation and few days after, the doctors called favorable for conception.
The probability of getting pregnant, knowing your ovulation: ovulation – from 6 to 13%; after ovulation – about 2%; during ovulation – 40%.
Ways to calculate ovulation
Ovulation – a very Moody and personal. Usually ovulation occurs before menstruation, for 12-16 days. There are several methods for getting the particular picture.
Measuring and recording basal (rectal) temperature. Temperature is measured in the morning at the same time in the rectum. In the beginning of the cycle the temperature is about 36.9 degrees. Before ovulation it falls by 0.4-0.6 degrees. In the second half of the cycle, it increased by about 0.5 degrees. Ovulation occurs when temperatures drop and before her promotion. To accurately calculate the time of ovulation by this method, it is necessary to record the temperature at least a few months, to conduct individual schedule.
Special ovulation tests. They determine the level hormone (LH) in urine. They are used for a few days before the estimated start of ovulation. Test shows ovulation, which will occur in the period approximately 24-48 hours.
The method of dynamic ultrasound. The doctor for an ultrasound can determine when and how the formation of the follicle in the ovary and the release of an egg. You need to pass 2 to 4 treatments. If the cycle is regular, doing ultrasound for 15-18 days before the new cycle. If menstrual cycle is irregular from 10 day cycle. This method allows to know the time of ovulation to within a few hours.
Cervical method. This method consists in the observation of the mucus in the cervix, since the last day of menstruation. During ovulation it becomes very viscous and transparent, like egg white. In other days, the mucus is creamy. Observations are carried out over several months, in the morning. The consistency of the mucus is tested with the help of toilet paper or manually.
Calendar method. Suitable for women with a stable menstrual cycle. For this method, you track your cycle for at least six months and record these dates in the calendar. You can roughly determine when you ovulate – this will be the fourteenth to sixteenth days of the menstrual cycle. This method is not very reliable. Ovulation can be displaced or not occur.
The need to determine the ovulation occurs when a woman wants a child or picks up the reliable natural method of contraception.
Advice 2: How many days lasts ovulation
The duration of ovulation does not depend on the duration of the menstrual cycle. The ripened egg that enters the fallopian tube, awaiting a meeting with sperm 24-48 hours.
The duration of ovulation
Ovulation is a process that is a prerequisite for conception. Once a month in one of the ovaries Matures an egg which enters the fallopian tube and waits for fusion with a sperm. For most women, ovulation occurs on day 14 after the first day of the menstrual period, but it all depends on the length of the cycle.
For example, in some people it lasts for 20 days, others 35. Despite individual differences, it is safe to say that the one thing that remains the same is the duration of ovulation. It is only 24-48 hours, i.e. a day or two. It would seem that this is an incredibly small window for conception, but we should not forget that sperm can remain in the reproductive paths of women 3-5 days, while retaining its activity. Therefore, even if the woman doesn't know what day is ovulation, it may increase the risk of fertilization, making love 2-3 days before the release of the egg. In this case, the sperm will have time to go through the process of capacitated (maturity) and will patiently "wait" for her.
How to determine the day of ovulation?
Modern medicine offers women several ways to determine ovulation. One of them is the measurement of basal (rectal) temperature. It is based on the fact that in the second phase of the cycle, after ovulation, the temperature indicator in the rectum increases. Also the day of ovulation can be determined using specific tests, which respond to luteinizing hormone (LH) contained in a woman's urine. Its level increases dramatically in 24-48 hours before ovulation.
However, one of the most effective ways to determine a day "x" is monitoring cervical fluid. Before the onset of ovulation, vaginal secretions become more viscous, rich and perfect in appearance they resemble egg whites. This method is not suitable for women suffering from polycystic ovary syndrome, who may experience systematic profuse discharge throughout the menstrual cycle. In the absence of health problems, the woman found themselves highlight cervical fluid (fertile mucus), 8, 9, 13, 16, 17 and 18 of your menstrual cycle, can assume that sexual intercourse in the 17th and 18th the day will help to conceive a child. If the ovulation process is accompanied by painful sensations - it is necessary to visit gynecologist.
