Menstrual cycle - easy to understand

The menstrual cycle is a normal process that women experience. It involves their reproductive system and whole body, considering the impact on emotions and feelings.

It is necessary to prepare the uterus for pregnancy and shed the uterine lining if pregnancy does not occur. The menstrual cycle is divided into several phases, each of which has specific characteristics and functions.

However, it is essential to note that every woman is different, and the menstrual cycle can vary significantly from one woman to another.

For example, some women may have longer or shorter menstrual cycles than others, and the length of their menstrual cycle may vary from month to month. Additionally, the timing and duration of each phase of the menstrual cycle can vary, and some women may experience more or fewer symptoms during each step.

Furthermore, some women may have irregular menstrual cycles, which means they are not regular and predictable. Factors such as hormonal imbalances, stress, illness, or other health conditions can affect irregular cycles.

The menstrual cycle has four key steps.

• The first phase of the menstrual cycle is the menstrual phase, also known as the menstrual period.

a. The first day of bleeding (period) is day 1 of the menstrual cycle. This phase typically lasts for 3-7 days and is marked by the shedding of the uterine lining. This shedding causes the woman to experience vaginal bleeding, a normal part of the menstrual cycle.

b . The menstrual phase is the least fertile time of the menstrual cycle.

c . This phase is a time of hormonal changes as the levels of estrogen and progesterone drop. These changes help to trigger the shedding of the uterine lining and the onset of the menstrual period.

d. The menstrual phase is a time of physical and emotional changes as the body adjusts to the hormonal changes and prepares for the next phase of the menstrual cycle. Some women may experience cramps, bloating, mood changes, and fatigue during this phase.

The menstrual phase is an important phase of the menstrual cycle, as it marks the beginning of the menstrual cycle and sets the stage for the rest of the process. It is a time of hormonal and physical changes and the least fertile time of the menstrual cycle.

• Another phase of the menstrual cycle is the follicular phase. This phase lasts from the first day of menstruation to the day of ovulation. During this phase, the ovaries produce follicles, which are tiny sacs that contain the eggs. One of these follicles will eventually mature and release an egg, which is known as ovulation.

During this phase:

1. The levels of the hormones estrogen and progesterone begin to rise. These hormones help to prepare the uterus for pregnancy and stimulate the growth and development of the follicles.
2. The uterine lining, or endometrium, thickens and becomes more vascular. This provides a suitable environment for a fertilized egg to implant and develop.
3. The cervix produces cervical mucus, which becomes thinner and more watery. This helps to transport sperm from the vagina to the uterus, making it easier for sperm to reach the egg.
4. The body undergoes various changes in preparation for ovulation. The pituitary gland releases hormones that stimulate the ovaries to produce and release eggs, and the cervix becomes more receptive to sperm.

The follicular phase is a crucial phase of the menstrual cycle, marking the beginning of the most fertile time of the month. During this phase, the body prepares for ovulation and the potential implantation and development of a fertilized egg.

• The third menstrual cycle phase is the ovulatory phase, which occurs on the day of ovulation. This is the most fertile time of the menstrual cycle, as it is the time when the mature egg is released from the ovary and can be fertilized by sperm.

During this phase, the following events take place:

1. The mature egg is released from the follicle and enters the fallopian tube. This process, known as ovulation, is the most important event of the menstrual cycle regarding fertility. It is the time when the egg can be fertilized by sperm.
2. The cervix produces large amounts of cervical mucus, which becomes thin, clear, and stretchy. This consistency, known as "egg white" cervical mucus, helps to transport sperm from the vagina to the uterus, making it easier for them to reach the egg.
3. The uterus becomes more receptive to a fertilized egg. The uterine lining, or endometrium, is at its thickest and most vascular, providing an ideal environment for a fertilized egg to implant and develop.
4. The body undergoes various changes in response to the release of the egg. The pituitary gland releases hormones that stimulate the ovaries to produce and release eggs, and the cervix becomes more receptive to sperm.
5. If the egg is not fertilized, it will deteriorate and eventually be absorbed by the body. This marks the end of the ovulatory phase and the beginning of the luteal phase.

The ovulatory phase is the most fertile time of the menstrual cycle. During this phase, the egg is released and can be fertilized by sperm, setting the stage for a potential pregnancy.

• The fourth phase of the menstrual cycle is the luteal phase. This phase begins after ovulation and lasts until the next menstrual period. 

During this phase, the following events take place:

1. The empty follicle that released the egg transforms into a structure called the corpus luteum. The corpus luteum produces hormones that help to prepare the uterus for pregnancy.
2. If the egg is fertilized, it will travel down the fallopian tube toward the uterus. If it successfully implants in the uterine lining, it will begin to develop into an embryo.
3. If the egg is not fertilized, the corpus luteum will eventually break down, causing a drop in hormone levels. This will trigger the shedding of the uterine lining and the onset of the next menstrual period.
4. The body undergoes various changes in response to the changes in hormone levels. The uterus begins to shed its lining, and the cervix produces less cervical mucus. These changes help to prepare the body for the next menstrual cycle.

The luteal phase is an important phase of the menstrual cycle, as it marks the end of the most fertile time of the month. During this phase, the body prepares for either pregnancy or the onset of the next menstrual period.

While the menstrual cycle is generally divided into distinct phases, it is essential to remember that every woman is different. It can vary significantly from one woman to another. It is necessary for women to pay attention to their own menstrual cycle and to understand what is normal for them.
