What Happens in Your Body During the Menstrual Cycle

The Menstrual Cycle and Hormonal Regulation
The menstrual cycle is a complex physiological process that occurs in females, typically lasting an average of 28 days. This cycle is intricately regulated by various hormones that work in concert to prepare the body for potential pregnancy. The cycle begins with the thickening of the uterus lining and the maturation of eggs in the ovarian follicles. Around day 14 of the cycle, a single egg is released during ovulation. If fertilization does not occur, the egg and uterus lining are shed approximately 14 days after ovulation, marking the beginning of a new cycle.
Definition: The menstrual cycle is the regular natural change that occurs in the female reproductive system, allowing for reproduction and involving the shedding of the uterine lining if pregnancy does not occur.
The hormonal regulation in menstrual cycle is a key aspect of this process, involving several important hormones:
- Follicle Stimulating Hormone (FSH): Secreted by the pituitary gland, FSH stimulates the maturation of eggs within the ovarian follicles and prompts the ovaries to produce estrogen.
Vocabulary: FSH (Follicle Stimulating Hormone) is a hormone produced by the pituitary gland that stimulates the growth of ovarian follicles and the production of estrogen.
-
Estrogen: Produced by the ovaries in response to FSH, estrogen stimulates the growth of the uterine lining. High levels of estrogen inhibit FSH production and stimulate the release of luteinizing hormone (LH).
-
Luteinizing Hormone (LH): Also secreted by the pituitary gland, LH plays a crucial role in ovulation. The effects of luteinising hormone on ovulation include stimulating the release of a mature egg from the ovary. LH levels surge just before ovulation and then decrease afterward.
Highlight: The surge of luteinizing hormone (LH) is a critical trigger for ovulation, causing the release of a mature egg from the ovary.
- Progesterone: After ovulation, the empty egg follicle, now called the corpus luteum, secretes progesterone. The role of progesterone during menstrual cycle is multifaceted:
- It helps maintain pregnancy if the egg is fertilized.
- It inhibits the production of FSH and LH.
- It maintains the uterine lining in the second half of the cycle, preparing it to receive a potential embryo.
Example: If fertilization does not occur, progesterone levels drop, leading to the shedding of the uterine lining, which we know as menstruation.
If the egg is not fertilized, the levels of all these hormones decrease, causing the uterus lining to break down and be shed from the body. This marks the end of one cycle and the beginning of a new one, with FSH and estrogen levels starting to rise again.
Quote: "After ovulation, the empty egg follicle secretes progesterone. Progesterone would help to maintain pregnancy if the egg was fertilised."
Understanding this intricate hormonal dance is crucial for comprehending female reproductive health, fertility, and the various phases of the menstrual cycle. It also provides insights into potential issues that may arise due to hormonal imbalances or disruptions in this delicate system.

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7. I didnโt even know about this app three days until the exam and it has helped A LOT. Please actually trust me and use it as Iโm sure you too will see developments.
