What is the average luteal phase?

also known as the secretory phase, the luteal phase is the last phase of the menstrual cycle. At the beginning of the average luteal phase, a temporary endocrine structure called corpus luteum is created. Corpus luteum excludes progesterone and estrogen to thicken the endometrium to prepare for implantation. The luteal phase ends in every pregnancy if the fertilization of the egg, or the decay of the luteum corpus, provided that fertilization does not occur.

Corpus luteum after ovulation continues to grow and produces large number of hormones, especially progesterone. If there is no pregnancy, then Corpus luteum decline leads to the sink of progesterone and estrogen levels that trigger the end of the average luteal phase. At this time, Corpus Luteum is cleaned from the body by menstruation and the cycle continues again. If the embryo is implanted during the luteal phase during the high basal body temperatures and produce progesterone for 8-12 weeks, then the placenta takes over this role.

The average luteal phase has a duration of 14 days, but can range anywhere from 10-16 days. If the luteal phase of the woman drops below the 12 -day period, he may have difficulty conceived. The luteal phase, which is below 10 days, is considered to be a sign of the luteal phase defect (LPD), which can also occur when progesterone levels are lower than usually during the average luteal phase. The below -average luteal phase cannot effectively support pregnancy due to the fact that the decomposition of the uterus is falling apart, causing menstrual bleeding and subsequently, premature abortions.

There are different potential causes of LPD and medical examination can determine whether a combination of more than one prevents the patient to be stable. Low follicle production is the cause of LPD because Corpus luteum develops from the follicle. If Corpus Luteum is able to create, its premature disintegration or inability to equalize the uterus with progesterone could prevent pregnancy. The most common cause lHowever, PD is a low level of progesterone in the body that your doctor can diagnose using a progesterone test and is truly truly.
