in the female body during the month there is a lot of changes that are associated with the work of the reproductive system.For example, for 10-16 days before the onset of menstruation, after ovulation occurs luteal phase of the cycle.
The menstrual cycle is divided into two main phases: before ovulation - and after follicular - lutein.Phase preceding ovulation can last for different time periods and not only different women, but each of them.As a rule, this phase determines the duration of the cycle, and it affects the delay menstruation, since the phase of the corpus luteum is almost always the same.
phase corpus luteum
luteal phase of the cycle normally can last for 12-16 days, but generally lasts no more than fourteen days.If the corpus luteum does not function sufficiently, it is possible shortening of the luteal phase.It should be noted that such a feature of an organism can be one of the causes of miscarriage in early pregnancy.To diagnose this problem is possible only with the help of ultrasound and blood test for progesterone.Thus luteal phase determined what day of the cycle, and normally if the level of the hormone in a woman's body.
As a rule, after the establishment of the causes and treatment of the primary disease level of progesterone in the body to normal.But in some cases, a woman prescribed progesterone and corpus luteum stimulation drugs containing human chorionic gonadotropin.
during pregnancy or in the presence of the corpus luteum cyst duration of the luteal phase can be increased.Generally this treatment is not required, this brush passes without interference.
What characterizes the luteal phase of the cycle
luteum phase begins right after ovulation.Isolation of luteinizing hormone in the menstrual period is terminated, and in the follicle from which the matured ovum starts functioning corpus luteum.That depends on him progesterone hormone production and normal development of the pregnancy.Since ovulation rate of progesterone ranging from the smallest figure - the highest value to 6.99 - 56.63 * n mol / l.This is the luteal phase of the cycle.On the seventh day progesterone begins to accumulate, and its level gradually decreases to the beginning of the next menstruation.
In the same period in the womb will actively increase the uterine lining.In the first half of the menstrual cycle is marked its strong growth by increasing hormone levels, but after the arrival of ovulation it becomes thicker and more absorbent.Because of this fertilized egg, entering the uterus, can freely penetrate into the uterine lining.
luteal phase of the cycle - a kind of standby mode, in which the body.He is ready for childbearing and produces hormones that will contribute to the maintenance of the embryo in the first few weeks after conception.But if around the tenth day the fertilized egg is not implanted in the uterus, the corpus luteum begins to slowly die off, the level of progesterone drops, the uterine lining is torn away and menstruation begins.
