What are the three phase of menstrual cycle?
Changes During the Menstrual Cycle The menstrual cycle has three phases: Follicular (before release of the egg) Ovulatory (egg release) Luteal (after egg release)
What happens in each phase of the menstrual cycle?
The follicular phase: The time between the first day of the period and ovulation. Estrogen rises as an egg prepares to be released. The proliferative phase: After the period, the uterine lining builds back up again. Ovulation: The release of the egg from the ovary, mid-cycle.
What is ischemic phase?
Ischemic phase: last part of the secretory phase with ischemia due to blood deficiency, endometrium pales, and spiral arteries constrict intermittently due to decreased hormone secretion by the degenerating corpus luteum.
What is the proliferative phase and secretory phase?
Proliferative phase (Follicular Phase): Endometrial cells proliferate and the lining thickens. Secretory phase (Luteal Phase): An egg is expelled from the ovary (ovulation) into the pelvic cavity. Premenstrual phase The endometrium continues to mature until a sudden drop in hormone levels triggers menstruation.
What is luteal or secretory phase?
The next phase of the menstrual cycle is the luteal or secretory phase. This phase always occurs from day 14 to day 28 of the cycle. Progesterone stimulated by LH is the dominant hormone during this phase to prepare the corpus luteum and the endometrium for possible fertilized ovum implantation.
What are the different stages of the menstrual cycle?

The follicular phase starts on the first day of your period (so there is some overlap with the menstrual phase) and ends when you ovulate. 3 Ovulation phase. 4 Luteal phase. 5 Identifying common issues.
What is the luteal phase of menstrual cycle?
Luteal phase (From day 15 to 28) Menstrual phase (day 1-5) Menstrual phase begins on the first day of menstruation and lasts till the 5th day of the menstrual cycle. The following events occur during this phase:
What happens on the 15th day of the menstrual cycle?
Luteal phase (day 15-28) This phase begins on the 15th day and lasts till the end of the cycle. The following events occur during this phase: The egg cell released during the ovulation phase stays in the fallopian tube for 24 hours. If a sperm cell does not impregnate the egg cell within that time, the egg cell disintegrates.
What happens during menstrual phase?
Menstrual phase begins on the first day of menstruation and lasts till the 5th day of the menstrual cycle. The following events occur during this phase: The uterus sheds its inner lining of soft tissue and blood vessels which exits the body from the vagina in the form of menstrual fluid.
