Hormones During Menstrual Cycle

What Are the Main Hormones Involved in the Menstrual Cycle?

 

The menstrual cycle is regulated by a delicate interplay of hormones, primarily estrogen, progesterone, luteinizing hormone (LH), and follicle-stimulating hormone (FSH). The brain and the ovaries produce these hormones and work together to prepare the body for potential pregnancy. Click here for more details.

How Does Follicle-Stimulating Hormone (FSH) Affect the Menstrual Cycle?

 

The pituitary gland produces follicle-stimulating hormone (FSH) and plays a critical role in the early stages of the menstrual cycle. FSH stimulates the growth of ovarian follicles, each containing an egg, during the first half of the cycle. As the follicles grow, they produce estrogen, which helps to regulate the cycle and prepare the uterine lining for a potential pregnancy. Read more about FSH here.

What Role Does Luteinizing Hormone (LH) Play in Ovulation?

 

Luteinizing Hormone (LH) is another hormone produced by the pituitary gland. It surges around the middle of the menstrual cycle, triggering ovulation, which is the release of an egg from the dominant ovarian follicle. This surge in LH is a crucial step for fertility, as it allows the egg to be fertilized by sperm. Learn more about LH here.

How Does Estrogen Influence the Menstrual Cycle?

 

Estrogen is an essential hormone produced by the growing ovarian follicles. It plays a vital role in building up the uterine lining, or endometrium, in the first half of the menstrual cycle. High levels of estrogen help to thicken the endometrium, making it a suitable environment for a potential pregnancy. This hormone also provides feedback to the brain to regulate the production of FSH and LH. Find more information on estrogen here.

What Is the Function of Progesterone After Ovulation?

 

After ovulation, the ruptured follicle transforms into the corpus luteum, which produces progesterone. Progesterone’s primary function is stabilizing and maintaining the uterine lining, making it ready for implantation if fertilization occurs. If pregnancy doesn’t happen, the levels of progesterone fall, leading to the shedding of the uterine lining, which is experienced as menstruation. Discover more about progesterone here.

How Do Hormones Change Throughout the Menstrual Cycle Phases?

 

The menstrual cycle is divided into several phases: the menstrual phase, the follicular phase, ovulation, and the luteal phase. Distinct hormonal changes characterize each phase:

 

• • Menstrual Phase: This phase marks the start of the cycle, where the uterine lining sheds, leading to menstruation. Hormone levels are at their lowest.

 

• • Follicular Phase: FSH levels rise, stimulating the growth of follicles and increasing estrogen production. This phase ends with a surge in LH.

 

• • Ovulation: The LH surge triggers the release of an egg from the dominant follicle.

 

• • Luteal Phase: Progesterone levels rise to maintain the uterine lining. If pregnancy doesn’t occur, progesterone and estrogen levels decrease, leading to menstruation.

 

 

More details on menstrual cycle phases are here.

What Happens to Hormones During the Menstrual Phase?

 

The menstrual phase begins the menstrual cycle, marked by the shedding of the uterine lining. Hormone levels, particularly estrogen and progesterone, are at their lowest during this phase. This hormone drop triggers the shedding of the endometrium, leading to menstrual bleeding. The low hormone levels also signal the pituitary gland to produce FSH, initiating the next cycle. Read more about the menstrual phase here.

How Do Hormones Influence the Follicular Phase?

 

The follicular phase follows the menstrual phase and involves the growth and maturation of ovarian follicles. FSH levels rise, stimulating several follicles to grow. These growing follicles produce estrogen, which helps to rebuild the uterine lining. As estrogen levels increase, they provide negative feedback to the brain, decreasing FSH production and ensuring that only the dominant follicle continues to mature. Learn more about the follicular phase here.

What Triggers Ovulation in the Menstrual Cycle?

 

Ovulation is triggered by a surge in LH, which occurs around the middle of the menstrual cycle. This LH surge is stimulated by the high estrogen levels produced by the dominant follicle. The surge causes the mature follicle to release its egg, which then enters the fallopian tube, where it can potentially be fertilized by sperm. Ovulation is a critical event for fertility and marks the transition from the follicular phase to the luteal phase. More on ovulation here.

What Is the Role of Hormones in the Luteal Phase?

 

The luteal phase begins after ovulation and is characterized by the production of progesterone by the corpus luteum. Progesterone’s primary role is maintaining the uterine lining, making it suitable for implantation if fertilization occurs. Estrogen levels also remain elevated to support the endometrial lining. If pregnancy does not occur, the corpus luteum degenerates, leading to a drop in progesterone and estrogen levels, which triggers menstruation. Read more about the luteal phase here.

How Do Hormonal Imbalances Affect the Menstrual Cycle?

 

Hormonal imbalances can significantly impact the menstrual cycle, leading to irregular periods, heavy bleeding, or missed cycles. Conditions like polycystic ovary syndrome (PCOS), thyroid disorders, and stress can disrupt the balance of hormones, affecting the regularity and symptoms of menstrual cycles.
