What is the connection between menstruation and ovulation?

Menstruation and ovulation are part of a human woman's reproductive cycle, also called menstrual cycle. In a typical reproductive cycle, menstruation and ovulation is separated for about nine days, although it differs from man to man and cycle to cycle. The average length of the menstrual cycle is only more than 29 days.

The menstrual cycle is divided into four main phases. Menstruation is the first phase where the uterus lining is called endometrium. Blood and endometrial tissue are pushed from the body through the vagina. Menstrual cramps are the result of muscle that eliminate the endometrium. During this phase, the body releases hormones that stimulate the growth of the ovarian follicle. As the follicle grows, it releases a hormone called estradiol, which stimulates the growth of endometrium.

ovulation is the third phase. As the ovarian follicle ripens, the growing estradiol levels cause the release of the luteinizing hormone (LH) that causes the follicle to release a secondary oocyte that matures into the egg or egg. Vajka leaves the ovaries, vsTupid into the fallopian tube and stays there for about one day. If it is fertilized by a spermatozoon, it is implanted in the endometrium and eventually matures into the embryo; If not, it will disintegrate in the watercourse.

In the luteal phase, also known as secretory phases, the remaining parts of the ovary are converted to a body called corpus luteum, which releases more hormones, including progesterone. These hormones make endometrium more receptive to implantation of a fertilized egg. If no eggs are implanted, Corpus luteum atrophy and the level of progesterone, causing the endometrium to shed and cycling and ovulation to start again.

menstruation and ovulation are usually slightly regularly regularly and predictable, but a number of conditions may disrupt the relationship between menstruation and ovulation and thus with the functioning of the cycle. Hormonal or chemical imbalance, low body weight, some diseases and other physical factors can lead to anThe elaci in which the menstrual cycle occurs, but the woman ovulates. Anovulation can cause irregular periods or stop complete menstruation, a state called amenorea. Alternatively, excessive bleeding may occur. Anovulation is usually treatable and treatment restores the functioning of the menstrual cycle.
