The tissue that lines the uterus (womb). Cyclic hormonal changes influence the growth and subsequent shedding of endometrial tissue. Endometriosis is the growth of this tissue outside its normal confines.
a specialized tissue that lines the uterus and undergoes changes during the menstrual cycle. It builds up (proliferates) under the influence of estrogen during the follicular phase before ovulation. Following ovulation under the influence of progesterone as well as estrogen it becomes more mature ( secretory) and ready for egg implantation. Endometrial shedding occurs normally with a decrease in estrogen and progesterone levels but occurs with decreases in estrogen levels in anovulatory cycles and also despite continued high levels of estrogen. Estrogen stimulates and progesterone inhibits the endometrium.
The blood and mucus lining that grows in the uterus during the first stage of the menstrual cycle. Menstrual â€œbloodâ€ is a mixture of mucus and secretions from the vagina and the cervix with the blood and mucus of the endometrium.
The innermost layer of the uterine wall. The endometrium undergoes changes in response to female hormones, resulting in a 28-day cycle involving menstruation during which much of the endometrium is sloughed off to be rebuilt again.
the lining of the uterus that swells after ovulation to receive an egg and is sloughed off during menstruation if implantation doesn't take place. "Endometritis" refers to inflammation of the endometrium. "Endometriosis" refers to growth of the endometrium outside the uterus, which can result in damage to the reproductive system and, possibly, infertility.
The mucous membrane lining of the uterine cavity that is hormonally responsive during the MENSTRUAL CYCLE and PREGNANCY. The endometrium undergoes cyclic changes that characterize MENSTRUATION. After successful FERTILIZATION, it serves to sustain the developing EMBRYO.
The layer of glands that line the inside of the uterus. Most of the uterine wall is comprised of smooth muscle. The endometrium responds to estrogen, growing thicker during the first two weeks of the menstrual cycle. After ovulation the ovarian hormone production changes from primarily estrogen to primarily progesterone. Progesterone helps to mature the endometrium, preparing it for implantation of an embryo. If pregnancy does not occur, the menstrual cycle begins two weeks after ovulation. The theory of retrograde menstruation states that endometriosis arises from endometrium which is implants inside of the body after flowing back through the fallopian tubes during a woman's menstrual cycle.
the lining of the uterus (womb). If a woman becomes pregnant the fertilised egg attaches itself to this lining and an embryo starts to develop. If the egg that the woman produces is not fertilised, the lining of the uterus passes out of her body each month (see menstruation). This is called a period.
"The inner most wall of the uterus that is shed each month during menstruation. It forms a lining of mucous membrane that is composed of three layers of tissue: a compact internal surface layer (mucosa), a spongy middle layer (sub-mucosa) and an outer layer that attaches the endometrium to the myometrium (basalis). The thickness changes during the different uterine phases of the menstrual cycle."
Lining of the uterus which is shed each month during menses strogen Female sex hormones The female hormone responsible for ovulation. It's production is signaled by the pituitary gland in the brain Estrogen Replacement Therapy Also referred to as Hormone Replacement therapy. The practice of medically administering estrogen after procedures such as hysterectomy or menopause-inducing drugs to reduce side effects and reduce medical risks such as osteoporosis
Membrane lining the uterus. The endometrium thickens throughout the menstrual cycle, until ovulation. If fertilization takes place, the egg can then implant in the uterus; if not, menstruation will occur, the endometrial lining ready to receive the fertilized egg will degenerate and be flushed out of the uterus with blood.
The lining of the uterus which builds up due to increasing amounts of oestrogen during the follicular phase of the menstrual cycle. After ovulation, under the influence of progesterone, the lining of the uterus goes through a secretory phase and is prepared for an embryo to embed. If pregnancy does not occur the endometrium is shed - known as menstruation or a period.
The lining of the uterus that is shed through menstruation each month as the menstrual period. As the monthly cycle progresses, the endometrium thickens into zones (seen on ultrasound) and provides a nourishing place for the embryo to attach and begin the process of placental development.
The lining of the uterus. Estradiol (E2) A hormone, produced by egg follicles, which is monitored through blood tests during the stimulation step of IVF to determine the drug dosage required by patients.
the lining of the uterus (womb). The endometrium becomes thicker as the menstrual cycle advances in preparation for a fertilized egg. If no fertilization occurs, the endometrium is shed with every period.
The lining of the uterus that is shed each month as the menstrual period. As the monthly cycle progresses, the endometrium thickens and thus provides a nourishing site for the implantation of a fertilized egg.
The inner lining of the uterus, the thickness and structure of which varies with the different phases of the menstrual cycle. The growth of this lining is stimulated by estrogen. After ovulation, with progesterone, the character of the lining changes, preventing further growth. The drop in estrogen and progesterone that occurs at the end of the cycle initiates the sloughing of the endometrium, the period.
part of the female reproductive system. The endometrium is the tissue lining the uterus. The endometrium is shed monthly when a woman menstruates. In pregnancy, the embryo implants into the endometrium and receives nourishment through it.
