WOMENS PROBLEMS: WHEN THE EGG IS NOT FERTILIZED
Monday, July 11th, 2011In most cases, fertilization does not take place. So, the single cell, with its 22 chromosomes plus the X or Y fellow, finally arrives at the uterus, with its lining still prepared to accept a pregnancy.
However, unless It is implanted (as the doctors say) within seven days and H.C.C. production commences (to force corpus luteal activity into manufacturing even greater quantities of oestrogen and progesterone), everything suddenly starts to falter. The corpus hue urn in the ovary rapidly ceases production of hormones. The uterine lining immediately notices this cessation, and lashes back. It sums to crumble. The lining simply falls to pieces.
Bleeding of unclotted blood commences, and the woman knows that a menstrual bleed has started. This will continue anywhere from one to eight days, usually averaging five. Anywhere from 10 to 120 mL of blood is lost, and the average amount each month is about 50 mL.
The uterine lining breaks down irregularly, and a process of fibrinolysis takes place to prevent dotting of the material. It has the appearance of dark blood but really is a mixture of broken down products of the uterine lining.
Contractions of the uterine wall help to expel the blood. Some women experience cramps at this time, and various other forms of discomfort, which will be discussed in more detail later on. In fact, life may be extremely uncomfortable. But this is the exception rather than the rule.
Normally, menstrual bleeding occurs with consistent regularity, exactly 14 days from the dare of ovulation. Although some variations do occur, it is generally remarkably constant.
Bleeding occurs until the uterine walls are completely free from all of the original lining. The surfaces left are raw. But within a very short span of time, new cells start to grow.
As outlined earlier, there is a close relationship between the ovarian hormones circulating in the bloodstream, and the pituitary gland and hypothalamus in the brain. As hormonal levels in the blood gradually fall, this causes renewed activity in the pituitary and hypothalamus, and they quickly recommence to release further amounts of follicle-stimulating hormone and luteinizing hormone. Once more the cycle starts.
So the process goes on and on. It is seemingly never-ending, his a remarkable story of persistence and perseverence. Surely it is an object lesson to us all.
Doctors often talk about specific days in the menstrual cycle, and it is worth knowing how this numbering works.
Day 1 is considered to be the day menstrual bleeding starts. Everything dates from this particular day. Numbering has nothing to do with the day bleeding ceases. Women sometimes become confused over this, especially if taking medication that is geared to menstrual days. On average, there are 28 days between successive menstrual bleeds—dial is. Day 1 to the next Day 1 of the successive cycle. Although this is an average, many women experience fairly wide variations, yet are still within normal limits.
