What Is Follicular Phase Of Menstrual Cycle
The menstrual cycle is more than just menstruation. It is a chain of activities in the brain, ovaries and uterus linked to
Understanding The Menstrual Cycle
; the chemical signals sent through the blood from one part of the body to another (1). The cycle is divided into two smaller cycles: uterine cycle and ovarian cycle (1).
, in other words different stages (1). Different events occur in each phase. There are three phases in the uterine cycle: menstruation
Proliferative phase and secretory (before menstrual bleeding) (1). There are also three phases in the ovarian cycle: follicular (before ovulation), ovulation
The menstrual cycle is not always perfectly predictable (1). The length of menstrual cycles can vary from cycle to cycle (1, 2). Even in people with fairly predictable periods, ovulation may not occur on the exact same day each cycle (3). This can make it difficult to predict (1).
Luteal Phase Deficiency
) (1). Anovulation is more common in the first years of menstruation and when your cycle is coming to an end during (peri)menopause (1). It can also happen during breastfeeding or with certain conditions, such as polycystic ovary syndrome (PCOS) (1, 4). Sometimes ovulation may not occur, but a regular period may still occur, and there is no known cause (4).
The menstrual cycle is a very sophisticated process; it can often feel very complex. To help simplify this topic, we will talk about what happens in a menstrual cycle in a linear fashion, assuming ovulation occurs, but each body is unique. There isn’t really a “typical” menstrual cycle.
A menstrual cycle starts on the first day of menstruation and ends at the start of the next period. A full menstrual cycle usually lasts between 24 and 38 days (2), but the menstrual cycle can vary from person to person, cycle to cycle, and can also change over the years.
Cycle lengths change between menarche (when menstruation first starts at puberty) and menopause (when menstruation stops permanently) (5, 6).

Some people notice changes in their hair, skin, stools, chronic disease symptoms, mood, migraine headaches or even in the way they experience sex at different times of the menstrual cycle.
It is important to understand the menstrual cycle because it can affect the body from head to toe. People use different methods of cycle tracking to understand their experiences, get pregnant and prevent pregnancy. Hormonal birth control methods affect the cycle by either preventing ovulation, changing the lining of the uterus, or both. Before ovulation 1. Uterine cycle:
What: Blood from the previous cycle from inside the uterus is shed through the cervix and vagina. The endometrium, called
, is thinnest in this phase. A typical period can last up to 8 days (2), but on average lasts about five or six (7).

Hormones: Levels of estrogen and progesterone are typically at their lowest. This causes the top layers of the lining to release and leave the body.
What: Proliferative means growing rapidly. The uterus builds a thick lining while the ovaries prepare eggs for release (oocytes) (8)
(fluid-filled sacs containing eggs) at different stages of development in both ovaries (10, 11). The period ends about halfway through this phase. A follicle in one of the ovaries becomes the largest of all the follicles. It is called
And are about the size of a grain of sand (1-2 cm or 0.4-0.8 inches) (11, 12). This follicle is the one that is ready to be released at ovulation. For most people, the follicular phase lasts 10-22 days, but this can vary from cycle to cycle (7).

(FSH). FSH tells the ovaries to prepare an egg for ovulation (release of an egg from the ovary). The dominant follicle produces estrogen as it grows (13), which peaks just before ovulation occurs (12).
When: About midway through the menstrual cycle or 13 to 15 days before the start of the next period (14). This can change cycle to cycle. Ovulation divides the follicular and luteal phases of the ovarian cycle as well as the proliferative and secretory phases of the uterine cycle).
What: The dominant follicle reaches about 2 cm (0.8 in). When it ruptures, an egg leaves the ovary and enters the fallopian tube (10, 12). The release of an egg from an ovary is called ovulation.
Hormones: The dominant follicle in the ovary produces more and more estrogen as it grows larger. When estrogen levels are high enough, they send a signal to the brain. The brain then causes a dramatic increase in

(LH) (9). This spike is what causes the release of the egg (1). Estrogen levels drop right after ovulation (1).
(endometrium) prepares to support a pregnancy or to break down for menstruation. The cells in the lining make and release many types of chemicals.
”, cause the uterine muscle to spasm. These hormones rise after ovulation and are highest for a period (15, 16). Cramps help start menstruation. The blood vessels shrink and the uterine lining breaks down (9). The uterine cells produce less of these chemicals if pregnancy occurs (17).
When: From ovulation to the start of the next period. The luteal phase lasts about 14 days, but between 9 and 16 days is common (7, 14).

(9, 18). It makes the hormones progesterone and estrogen to support pregnancy. (9, 18). If pregnancy does not occur, the corpus luteum breaks down between 9 and 11 days after ovulation (9).
Hormones: Progesterone supports early pregnancy if an egg and sperm connect (19). If pregnancy does not occur, progesterone will peak and then decline (20). These hormonal changes can contribute to common premenstrual symptoms. Common symptoms are mood swings, headaches, acne, bloating and breast tenderness. A drop in progesterone and estrogen causes menstruation.

Endometriosis is a leading cause of pelvic pain and painful sex – up to 1 in 10 women of childbearing age may… The follicular phase is the first phase of a woman’s menstrual cycle, when the hormone FSH (follicle stimulating hormone) and estrogens are the most important hormones.
Menstrual Hygiene Management
The menstrual cycle begins with menstruation, so the first day of menstrual bleeding marks the beginning of the cycle and the start of the follicular phase.
This phase extends over a more or less variable period, but covers about 14 days of a typical 28-day menstrual cycle until ovulation occurs, that is, the release of a mature egg from the ovary.
Below is an index of the 7 points that we will elaborate on in this article.
The follicular phase is one of the phases that the female menstrual cycle can be divided into. Specifically, the follicular phase is the first phase of the cycle, which begins with the onset of menstruation.
What Happens In Your Menstrual Cycle?
This phase is characterized by the development of more follicles in the ovary, by the action of the FSH hormone or follicle-stimulating hormone. However, only one of them will complete this development, which is why it is called the dominant follicle
The remnants of the empty follicle in the ovary will form the corpus luteum, which will be responsible for secreting the progesterone that characterizes this phase of the menstrual cycle. The luteal phase extends from ovulation to the arrival of the next period (if pregnancy has not occurred).
Therefore, the follicular phase is a pre-ovulatory period in which follicular development takes place, leading to the release of an egg into the fallopian tubes, where it will await the possible arrival of a sperm cell to be fertilized.

During a woman’s menstrual cycle, it is important to be aware of the changes that occur in both the ovaries and uterus. In this case, the following are the main changes that occur at both levels in the follicular phase of the cycle.
The secretion of FSH hormone from the pituitary gland (in the brain) stimulates the development of more follicles in the ovary. However, one of the follicles will grow above the rest by a process of selection and dominance, the dominant follicle. Instead, the remaining follicles in the cohort will not continue their development and will degenerate in a process known as
Follicular development will cause the follicular granulosa cells to secrete estrogens. In this way, there will be an increase in estrogen levels as the follicular phase progresses due to the large production of the dominant follicle,
