Menstrual cycle - Ovulation - Conception
The menstruation, that is to say, the detachment of the internal coating of the uterus (the endometrium) accompanied of hemorrhage, it takes place in cycles approximately monthly, until the woman is embarrassed. It marks the reproductive years of the life of the woman, which they extend from the beginning of the menstruation (menarquía) and continue during the puberty up to menopause.
For definition, the first day of hemorrhage is the beginning of every menstrual cycle (the 1st), which finishes just before the following menstruation. The menstrual cycles lasts between 21 and 40 days and only 10 or 15 per cent they are exactly 28 days. The intervals between the periods are more prolonged in the years immediately. The menstrual cycle divides in three phases: folicular, ovulatory and leuteínic.
In the menstrual normal cycle an ovum is liberated of one of the ovaries about the 14th before the following menstruation. The liberation of the ovum is named an ovulation. The ovum reaches the end in the shape of funnel of one of the Fallopian tubes, where it is possible to produce the fertilization, and is transported up to the uterus. If it is not fertilized, the ovum degenerates and is eliminated across the uterus in the following menstrual period. If, on the contrary, a sperm manages to penetrate in the ovum and fertilizes it, this one begins to turn into embryo by means of a series of cellular divisions.
