Physiological Effects of Estradiol and Progesterone Menstrual and Endometrial Cycle

ثبت نشده
چکیده

The female reproductive system consists of two ovaries, two fallopian tubes, the uterus, cervix and external genitalia. Every female undergoes a monthly cycle of 28 days, in which an egg is released from either ovary and the lining of the uterus is prepared for the implantation of an embryo, which eventually sheds off in case fertilization does not occur. This normal physiological mechanism is controlled by a number of hormones, secreted by the hypothalamus, pituitary gland and ovaries themselves. Any aberration in the release of these hormones may result in menstrual cycle abnormalities or infertility.

Hormonal regulation and localization of estrogen, progestin and androgen receptors in the endometrium of nonhuman primates: effects of progesterone receptor antagonists.

This article reviews the effects of estradiol (E(2)), progesterone (P) and P receptor antagonists (PA) on the rhesus macaque endometrium. Ovariectomized macaques can be treated with implants of estradiol (E(2)) and P to induce precisely controlled, artificial menstrual cycles. During these cycles, treatment with E(2) alone induces an artificial proliferative phase marked by extensive endometria...

Endometrial and subendometrial perfusion are impaired in women with unexplained subfertility.

BACKGROUND We used three-dimensional power Doppler angiography (3D-PDA) to examine the periodic changes in endometrial development and subendometrial vascularity during the normal menstrual cycle in 29 women with unexplained subfertility and 19 controls. METHODS 3D-PDA was performed on alternate days from day 3 of the cycle until ovulation and then every 4 days until menses. VOCAL (Virtual Or...

P-191: A Comparison of The Effects of Transdermal Estradiol and Estradiol Valerate on Endometrial Receptivity in Frozen-Thawed Embryo Transfer Cycles: A Randomized Clinical Trial

Background: The aim of this prospective randomized clinical trial was to determine the optimal endometrial preparation protocol by comparing the clinical outcome of two methods of endometrial preparation in FET cycles, that is, oral estradiol and 17 β-estradiol transdermal patch. Materials and Methods: A total number of 90 patients were scheduled for FET. In the study group (n=45), 17-B estradi...

Gonadal steroids regulate the expression of aggrecanases in human endometrial stromal cells in vitro

The human endometrium undergoes cyclic change during each menstrual cycle in response to gonadal steroids. Proteolysis of endometrial extracellular matrix (ECM) is necessary to prepare this dynamic tissue for pregnancy. Proteolytic enzymes such as matrix metalloproteinase (MMP) and closely related a disintegrin and metalloproteinase with thrombospondin motifs (ADAMTS) have been assigned key rol...
