In this article, we will discuss a women’s menstrual cycle, ovulation and menstruation. Undoubtedly, no website will not replace a full medical consultation of the employee, however, we can provide a General picture of the principles of your body.
What is a menstrual cycle
Length of the female cycle are not the same. The most common cycle length ranges from 23 to 35 days. The difference in the duration of the menstrual cycle, generally, relates to the period before ovulation (the so-called follikulinovaâ phase). Most women from ovulation (when the egg is released from the ovary) before the start of menstruation takes place from 12 to 16 days (called the luteal phase).
The first day of the menstrual cycle is the first day of menstruation (day 1). Menstruation then lasts from 3 to 7 days. Surely, you know that in the presence of menstrual pains, the greatest pain you experience in the first few days of menstruation. This is because the hormones in your body cause the uterus to actively get rid of the mucous membrane, the accumulated surplus from the previous menstrual cycle.
Preparation for ovulation
At the beginning of your cycle pituitary gland of the brain produces follicle-stimulating hormone (FSH). It is the main hormone that stimulates the ovaries to produce egg cells. Follicles are fluid – filled vesicles in the ovaries. Each follicle contains an immature egg. FSH promotes the maturation of a certain number of follicles and the production of the hormone estrogen. On the first day of menstruation estrogen is at its lowest level. He then begins to rise along with the maturation of follicles.
With the development of follicles, usually one of them becomes dominant, and the egg Matures in a large follicle. At the same time increasing the level of estrogen in the body is responsible for building in the uterus mucosa, consisting of nutrients and blood. This is because in the case of pregnancy, the fertilized egg had all the nutrients and support needed for growth. High levels of estrogen also promotes the formation of a “friendly for sperm” mucus (or scientifically fertile cervical mucus). This slippery liquid discharge, which may have a cloudy whitish hue. Cum more easily moves through this mucus and survives for several days.
The level of estrogen in the body is growing steadily, and at some point it leads to a sharp increase in the level of luteinizing hormone (LH surge). An LH surge leads to rupture of the dominant follicle and leaving a ripe eggs, after which she falls into the end pipe. This process is called ovulation.
Many women believe that ovulation occurs on day 14, but 14 days is the average, and for most women, typically, ovulation occurs on a different day of the menstrual cycle. The day of ovulation differs from cycle to cycle. Some women claim to feel painful spasm during ovulation, but most women don’t feel anything, and ovulation takes place without any signs.
After the release of the egg travels from the fallopian tube into the uterus. Its life cycle is not more than 24 hours. Survivability of sperm more variable, but generally ranges from 3 to 5 days. Thus, the days before ovulation and the day of ovulation are the most fertile – that’s when you have the greatest chance of becoming pregnant. Immediately after ovulation, the follicle begins to produce another hormone – progesterone.
Progesterone facilitates the subsequent formation of the uterine lining in preparation for a fertilized egg. In addition, the empty follicle in the ovary begins to decline, but continues to secrete progesterone and begins to produce estrogen. At this time you may experience symptoms of premenstrual tension (PMS), such as breast tenderness, bloating, sleepiness, depression and irritation.
Getting ready for the next menstrual period
When the empty follicle is narrowed in the case of that isn’t fertilized ovum levels of estrogen and progesterone decrease. Without a high level of hormones to maintain the necessary environment endometrium begins to break down, and the body is freed from her. This is the beginning of menstruation and the next cycle.
The fertilized egg attaches to the lining of the uterus. Typically, this occurs one week after fertilization.
After attachment of the egg, your body starts producing the pregnancy hormone, human chorionic gonadotropin (HCG), which will support the activity of the empty follicle. It will continue to secrete estrogen and progesterone to prevent the destruction of the mucous membrane of the uterus until the placenta, which contains everything necessary for the embryo with nutrients, not ripe enough to maintain the pregnancy.
