differentiate between follicular phase and luteal phase of menstrual cycle
Answers
Answer:
The follicular phase
The follicular phase, which some people call the proliferative phase, also starts on the first day of a person’s period. It is simultaneous with the menstrual phase.
At the start of the cycle, a brain region called the hypothalamus signals the pituitary gland to release follicle stimulating hormone (FSH).
FSH stimulates the ovaries to create several small sacs called follicles. These each contain an immature egg. The healthiest egg will mature while the rest of the follicles will absorb back into the body.
As the follicle matures, the body releases extra estrogen. This stimulates the uterine lining to thicken. The thickened lining can provide the necessary nutrients to a fertilized egg.
The follicular phase typically lasts around 10–16 daysTrusted Source. This phase will end when a person ovulates.
The luteal phase
The final phase of the menstrual cycle is called the luteal phase.
During the luteal phase, the follicle morphs into a mass of cells called the corpus luteum. The corpus luteum releases progesterone, which will keep the uterine wall thick and ready for a fertilized egg to implant.
If the egg becomes fertilized, the body will produce human chorionic gonadotropin (hCG). hCG helps keep the uterine lining thick for the fertilized egg to develop into an embryo.
However, if the egg does not become fertilized during ovulation, the corpus luteum will dissolve into the body. Both estrogen and progesterone levels will drop, which marks the beginning of the menstrual phase.
During the luteal phase, a person may experience symptoms of premenstrual syndrome (PMS). These may include:
headaches
mood changes
bloating
pain, tenderness, or swelling of the breasts
changes in sex drive
weight gain
difficulty sleeping
food cravings
The length of the luteal phase can vary, but it tends to be around 14 daysTrusted Source on average.
