Menstrual Cycle, Ovarial-Menstrual Cycle

The Menstrual cycle, or the Ovarial-Menstrual cycle, is the periodic changes that occur in a woman’s body when she is not pregnant. These changes consist in the fact that every 28 days an egg matures in the ovary and is released from the follicle. Then it enters the fallopian tube and then into the uterine cavity.

This cycle repeats regularly until menopause. It consists of several phases:

1. Follicular growth phase. The maturation of the follicle with the egg in the ovary occurs under the influence of follicle-stimulating hormone.

2. Ovulation. A mature egg leaves the ruptured follicle and enters the fallopian tube.

3. Luteinization phase. At the site of the burst follicle, a corpus luteum is formed, which produces the hormone progesterone. Under its influence, the endometrium of the uterus is prepared for the possible implantation of a fertilized egg.

4. Menstruation. In the absence of fertilization, the functional layer of the endometrium is rejected, accompanied by bleeding.

5. Rest phase. Preparing for a new cycle.

Thus, the menstrual cycle reflects complex hormonal and morphological changes in the female body, aimed at preparing for a possible pregnancy. When it occurs, this cycle stops before birth.

The Menstrual and Ovarian Menstrual Cycle are periodic changes in a woman’s body that occur without pregnancy and are associated with the maturation of the egg in the ovaries and its entry into the uterus every four weeks. This process continues until menopause and is a major factor in women's reproductive health.

The stages of the menstrual cycle include the follicular and luteal phases, during which the maturation of the egg and the formation of the corpus luteum hormone occur, respectively. During the follicular phase, the ovary produces estrogen, which prepares the uterine lining for egg implantation. During the luteal phase, as the egg matures, estrogen levels decrease and progesterone levels rise to prepare the lining for implantation.

When the egg passes through the fallopian tubes and enters the uterus, it can be fertilized by a sperm if it has the potential to become pregnant. If pregnancy does not occur, the corpus luteum gradually shrinks and hormone levels decrease, leading to the start of the next menstrual phase.

The importance of the Menstrual and Ovario-menstrual cycle is that it helps women track their menstrual cycles and manage their cycle if they want to get pregnant or are planning a pregnancy. Additionally, it may be associated with various medical conditions such as polycystic ovary syndrome (PCOS), which can lead to menstrual irregularities and other reproductive problems.

In conclusion, the menstrual and ovarian-menstrual cycle is an important process in women's reproductive health and can be used to control menstrual cycles and pregnancy planning.

The menstrual cycle, also known as the ovarian-menstrual cycle, is the periodic changes that occur in a woman's body during her reproductive years. It starts on the first day of your period and continues until menopause. An important element of this cycle is the maturation of the egg in the ovary and its subsequent implantation into the uterus for possible pregnancy.

The menstrual cycle consists of several phases that last for approximately 28 days. However, some women may have shorter or longer cycles. The main phases of the cycle include the follicular phase, ovulation, luteal phase and menstruation.

The follicular phase begins on the first day of menstruation. Under the influence of follicle-stimulating hormone (FSH), several follicles in the ovary begin to develop. Each follicle contains an immature egg. During this phase, the level of estrogen, the female sex hormone, gradually increases, promoting the growth of the endometrium, the inner layer of the uterus.

Ovulation occurs approximately in the middle of the cycle, usually on days 14-15. During this period, the mature follicle bursts and the egg is released from the ovary. This is the most favorable time for conception, as the egg is ready for fertilization and can pass through the fallopian tube into the uterus.

After ovulation, the luteal phase begins. The ruptured follicle turns into a corpus luteum, which produces the hormone progesterone. Progesterone keeps the endometrium ready to receive a fertilized egg by thickening its layer and increasing the number of blood vessels.

If fertilization does not occur, then menstruation occurs. At this point, the level of estrogen and progesterone drops, which leads to the rejection of the functional layer of the endometrium. The blood vessels that supplied the endometrium contract, causing bleeding known as menstruation. This process usually lasts about 3-7 days.

If the egg is fertilized, it is implanted into the endometrial layer and pregnancy begins. The corpus luteum continues to produce progesterone, supporting the early stages of pregnancy before the placenta is fully formed and takes over the function of maintaining the pregnancy.

The menstrual cycle is an important process in a woman’s life. It is associated with reproductive function and allows a woman to be able to become pregnant and bear offspring. The regularity and normal functioning of the menstrual cycle are indicators of the health of a woman’s reproductive system.

It is important to note that the menstrual cycle can be subject to various changes and variations at different periods of a woman’s life. For example, in adolescents, the initial years after the first menstruation may be characterized by irregular cycles, and in women before menopause, the cycle may become unpredictable and end with the permanent cessation of menstruation.

The menstrual cycle is an important part of a woman's reproductive system. Understanding its mechanisms and phases helps a woman to better plan her reproductive life and, if necessary, seek medical help. Various factors, such as stress, illness, weight changes and others, can affect the menstrual cycle. Therefore, it is important for a woman to lead a healthy lifestyle and consult a doctor if problems arise with the cycle or if there are questions about its regularity and characteristics.

In conclusion, the menstrual cycle, or ovarian-menstrual cycle, is a normal and natural process in a woman’s body. It is associated with reproductive function and includes various phases that ensure the body is ready for conception and pregnancy. Understanding and following the normal menstrual cycle helps a woman better manage her health and reproductive function.
