claimDuring the proliferative phase, rising estrogen levels signal the uterine lining to grow.
claimDuring the secretory phase, progesterone levels rise, causing the uterine lining to stop thickening and prepare for implantation.
claimMenstruation is the phase of the uterine cycle where the uterine lining sheds.
claimIn the late secretory phase, the body produces prostaglandins, which are hormone-like compounds that can cause cramps to help shed the uterine lining if pregnancy does not occur.
claimDuring the proliferative phase (occurring around days 6–14), the uterus rebuilds and thickens its lining to prepare for potential pregnancy, while the ovaries prepare eggs (oocytes) for release.
claimDuring the menstrual phase, the uterine lining (endometrium) sheds blood and tissue through the cervix and vagina, reaching its thinnest point.
claimDuring the menstruation phase of the uterine cycle, the uterine lining sheds.
claimDuring the menstrual phase, estrogen and progesterone levels are at their lowest, causing the top layers of the uterine lining to break down.
claimDuring the follicular phase of the ovarian cycle (which corresponds to the proliferative phase of the uterine cycle), the follicle in the ovary prepares an egg and the uterine lining rebuilds.

quoteDr. O'Connor states: "One of the main purposes of estrogen is to build a thick uterine lining, so estrogen lays down the bricks of the uterus, and progesterone lays down the cement."
claimHormonal shifts during the menstrual cycle regulate ovulation, uterine lining changes, and physical symptoms such as cramps, mood shifts, and energy fluctuations.
claimThe corpus luteum produces progesterone, which facilitates blood flow and nourishment to the uterine lining to support a potential fertilized egg.
claimEstrogen levels drop immediately after ovulation before rising again, with the primary purpose of building a thick uterine lining.
claimIf pregnancy does not occur, estrogen and progesterone levels drop, causing the uterine lining to shed and triggering the menstrual period.

claimA menstrual cycle is a reproductive system process that prepares the body for a possible pregnancy, beginning with the shedding of the uterine lining.
claimIf an egg is fertilized and implants in the uterine wall, pregnancy occurs; if pregnancy does not occur, estrogen and progesterone levels drop, causing the uterine lining to shed during the period.
claimIf an egg released during ovulation is not fertilized by sperm, the uterine lining breaks down and sheds, resulting in a menstrual period.
claimHormones during the menstrual cycle cause the uterine lining to thicken to prepare for potential egg implantation and trigger the ovaries to release an egg during ovulation.
claimThe menses phase of the menstrual cycle begins on the first day of a period and involves the shedding of the uterine lining through the vagina if pregnancy has not occurred.
claimMenstruation, also known as menses or a period, is the monthly shedding of the uterine lining, consisting of blood and tissue that flows from the uterus through the cervix and out of the vagina.

claimMenstruation is the periodic shedding of the uterine lining when pregnancy does not occur during a cycle, often referred to as a period.
procedureIf an egg is not fertilized, it dissolves in the uterus, and the uterine lining breaks down and sheds, which marks the beginning of a menstrual period.
claimIf a fertilized egg does not implant in the uterus, the uterine lining is shed as a menstrual period.
claimThe uterine lining thickens in response to the normal hormones of the menstrual cycle to prepare for potential implantation of a fertilized egg.
claimFertilization of an egg by sperm normally occurs in the fallopian tubes, after which the fertilized egg moves to the uterus to implant into the uterine lining.

claimDuring the menstrual phase, hormone levels are low, and the uterine lining sheds, resulting in menstrual bleeding.
claimDuring the follicular phase, estrogen thickens the uterine lining in preparation for pregnancy and influences physical and emotional health.
claimBefore a menstrual period begins, progesterone and estrogen levels rise to prepare the uterine lining; if pregnancy does not occur, these hormones drop sharply, which can cause premenstrual syndrome (PMS) symptoms.
claimThe rise in estrogen during the follicular phase is stimulated by follicle-stimulating hormone (FSH) produced by the pituitary gland, and this estrogen promotes the growth of the uterine lining in preparation for pregnancy.
claimDuring the luteal phase, progesterone levels continue to rise, which helps thicken the uterine lining.

claimEstrogen stimulates the thickening of the uterine lining during the follicular phase to prepare it to receive a fertilized egg.
claimIf an egg is fertilized and implants, the body produces human chorionic gonadotropin (hCG), which signals the corpus luteum to continue secreting progesterone to maintain the uterine lining and support early pregnancy.
claimIf an egg is not fertilized, the corpus luteum breaks down, causing a drop in progesterone levels that triggers the shedding of the uterine lining and the start of the next menstrual cycle.
claimDuring the luteal phase, the body secretes progesterone to prepare for potential pregnancy by maintaining the uterine lining.

claimDuring the luteal phase, the egg travels through the fallopian tubes to the uterus, and the uterine lining continues to thicken in preparation for pregnancy.
claimDuring the follicular phase, changing hormone levels cause the uterine lining to thicken and follicles to grow on the surface of the ovaries, with usually one follicle maturing into an egg.
claimDuring menstruation, the uterus lining sheds and exits through the vagina, consisting of blood, mucus, and cells from the uterine lining.
claimThe follicular phase begins on the first day of a period and lasts for 13 to 14 days, during which changing hormone levels cause the uterine lining to thicken and follicles to grow on the ovaries.

claimIf pregnancy does not occur, the proliferated endometrial lining breaks down and sheds, passing through the vagina as menstrual blood.
claimThe endometrial lining of the uterus proliferates each month to prepare for embryo implantation; if fertilization occurs, the uterus houses the fetus and placenta, but if pregnancy does not occur, the lining is shed during menstruation.
claimIf no ovum is fertilized, the endometrial lining is shed, signifying the beginning of menses, the first phase of the uterine cycle.
