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.
