To understand developing ureteroplacental circulation, a basic knowledge of the anatomy and physiology of uterine blood flow is helpful. Blood to the uterus is from the paired uterine arteries, which are branches of the anterior division of the internal iliac artery. As each uterine artery enters the uterus at the uterocervical junction, it ascends along the lateral uterine wall and produces multiple penetrating arcuate branches. When these branches pierce the endometrium, they become the spiral arteries. With early embryonic development, the spiral arteries located within the decidua basalis become increasingly prominent. Side-by-side maternal and embryonic circulations are established initially as trophoblastic cells form chorionic villi that invade into portions of the decidualized endometrium Fig. The villi simultaneously erode tiny portions of the decidua, which subsequently enlarge to form the intervillous spaces. The intervillous spaces will ultimately receive maternal blood from the spiral arteries, and thus the villi containing fetal blood will be surrounded and perfused by maternal blood by the end of the first trimester. Two hypotheses have been proposed to explain these events.

Urinary clearance is reduced by anencephalia lack of ACTH , therapeutic administration of corticosteroids to pregnant negative feedback , adrenal cortical hypoplasia, lack of placental sulfatase Y-linked trait , reduced placental tissue gestosis, delayed delivery , maternal liver diseases imparing conjugation, impaired enterohepatic circulation, severe renal diseases Across the animal kingdom, birth rate falls steadily with increasing food requirements.

Energy use is closely linked to size, so bigger animals have fewer offspring. This seemed not to hold for humans. A female gorilla weighs in at about kg, and can expect to have between 3 and 6 offspring. But human birth rates fit the pattern perfectly if you look at total energy consumption. Considering food, transport, heating, entertainment and so on, the average North American runs at 11, W: North Americans’ energy consumption is equivalent to the metabolism of a 30, kilogram primate.

And they have a birth rate to match. In darwinian terms, it doesn’t make sense that greater resources aren’t used to make babies.

Endometrial BCL6 Overexpression in Eutopic Endometrium of Women With Endometriosis

This chapter uses the term luteal phase deficiency LPD. Although it successfully can be argued that LPD is the most common abnormality of the menstrual cycle, its significance as a disease entity is shrouded in controversy over its incidence, means of diagnosis, and legitimacy of treatment. Since the first formal description of LPD in as a possible cause of infertility and recurrent miscarriage by Jones, 1 innumerable investigations have been undertaken in an effort to verify its existence or to characterize its pathophysiology, diagnosis, and treatment.

The consensus of the literature is that LPD does exist and that its cause is multifactorial e. These possible causes are not mutually exclusive in individual patients with LPD, which adds more fuel to the controversy. Obscuring the issue further are related syndromes, such as hyperprolactinemia and hypothyroidism, that are associated with LPD and may induce luteal phase abnormalities secondarily in the presence of otherwise normal ovarian and endometrial function.

WHY WOULD I NEED A FIRST TRIMESTER/DATING ULTRASOUND? Not all women need to have an ultrasound in this early part of the pregnancy. Your doctor may request this ultrasound for a number of reasons, including.

To analyze concentrations of endometrial leukocytes in patients with idiopathic-repeated abortions. Materials and methods Biopsies of exactly dated secretory endometrium in 25 patients with idiopathic-repeated abortions and 10 control patients without a history of miscarriage were compared with respect to the concentrations of T-helper cells CD4 , cytotoxic T-cells CD8 , B-cells CD19 and uterine natural killer cells CD56 by immunohistochemistry and RNase protection assays.

Results All examined cells were detectable within secretory endometrium. No statistically significant differences of the examined immune-cell concentrations were seen between the control group and the repeated miscarriage group by either test. Conclusion This study suggests that the concentrations of specific endometrial leukocytes in a non-pregnant cycle are not associated with repeated pregnancy loss. Thus, the hypothesis of an altered endometrial immunity in patients with repeated miscarriages, symbolized by persistently differing local immune-cell concentrations, has to be questioned.

It is asserted that examination of the endometrium during the secretory phase yields more information about the time of ovulation, degree of progestational change, and normality of the endometrium than any other test used in sterility studies. Attention to qualitative changes in 8 morphological factors is most useful in dating the endometrial biopsy. During the 1st week of luteal activity, attention should be focused on changes occurring in gland epithelium: During the 2nd week , stromal changes including edema , predecidual reaction, stromal mitosis, and leukocytic infiltration are the key criteria.

Tissue from the fundus of the uterus gives the most reliable information. These critera were used in sterility biopsies taken from normally menstruating women over a 3-year period. Absence of organic endometrial disease and availability of accurate menstrual history were the only selection criteria. To test the validity of the dating criteria, change in basal body temperature was used to correlate endometrial dating with ovulation rather than onset of menstruation. To determine whether biopsy caused early menstruation, the secretory phases of the 25 patients who had recorded temperatures in at least 2 cycles in addition to that in which the biopsy was taken were examined.

The secretory phase was definitely shorter in the biopsied than control cycle, suggesting that biopsy does accelerate the onset of flow. However, further analysis showed that biopsy does not interfere with length of flow or succeeding menstrual rhythm.

See Article History Alternative Title: Mammalia Mammal, class Mammalia , any member of the group of vertebrate animals in which the young are nourished with milk from special mammary glands of the mother. In addition to these characteristic milk glands, mammals are distinguished by several other unique features.

WHAT IS A PELVIC OR GYNAECOLOGIC ULTRASOUND? Gynaecology is the branch of medicine that deals with women’s health issues, especially the study and management of female pelvic disorders.

General features Diversity The evolution of the class Mammalia has produced tremendous diversity in form and habit. Living kinds range in size from a bat weighing less than a gram and tiny shrews weighing but a few grams to the largest animal that has ever lived, the blue whale , which reaches a length of more than 30 metres feet and a weight of metric tons nearly short [U.

Every major habitat has been exploited by mammals that swim, fly, run, burrow, glide, or climb. The rodents order Rodentia are the most numerous of existing mammals, in both number of species and number of individuals, and are one of the most diverse of living lineages. In contrast, the order Tubulidentata is represented by a single living species, the aardvark. The Uranotheria elephants and their kin and Perissodactyla horses , rhinoceroses , and their kin are examples of orders in which far greater diversity occurred in the late Paleogene and Neogene periods about 30 million to about 3 million years ago than today.

The greatest present-day diversity is seen in continental tropical regions, although members of the class Mammalia live on or in seas adjacent to all major landmasses. Mammals can also be found on many oceanic islands , which are principally, but by no means exclusively, inhabited by bats. Major regional faunas can be identified; these resulted in large part from evolution in comparative isolation of stocks of early mammals that reached these areas. South America the Neotropics , for example, was separated from North America the Nearctic from about 65 million to 2.

Some of the latter became extinct as the result of competition with more advanced groups, whereas those in South America flourished, some radiating to the extent that they have successfully competed with invaders since the rejoining of the two continents. Australia provides a parallel case of early isolation and adaptive radiation of mammals specifically the monotremes and marsupials , although it differs in that Australia was not later connected to any other landmass.

A pelvic or gynaecologic ultrasound is an ultrasound of the female pelvis. Most pelvic ultrasounds are performed using both the transabdominal and transvaginal approaches. Transabdominal ultrasound involves scanning through your lower abdomen. Transabdominal ultrasound usually provides an overview of the pelvis rather than detailed images. The transabdominal assessment is particularly helpful for the examination of large pelvic masses extending into the abdomen, which are not always well viewed with transvaginal ultrasound.

Ayurveda Research Papers CCA Student papers The selected papers published on our website have been written by students of the California College of Ayurveda as a part of their required work toward graduation. As the pituitary gland secretes LH and FSH, these hormones act on the follicle in the ovary and stimulate its maturation. At the ovary, estrogen and progesterone are released. At the same time, progesterone affects the development of the endometrium and the breast tissue.

The hormonal flow between the three glands is a negative feedback system; if the body has enough estrogen then no LHRH is produced, however, if estrogen levels are running low, than the hypothalamus secretes LHRH. A healthy menstrual cycle is dependent on functioning of the endocrine system. If pregnancy does not occur, than the endometrial lining is released.

References Progesterone Support in Pregnancy [Figure , p. Furthermore, most of the assessment of progesterone in pregnancy as it relates to various complications of pregnancy was accomplished from the early s through the early s. In spite of improvements in the accuracy and precision of progesterone assays since that time and a better ability to date pregnancy and establish more accurate gestational ages, very little subsequent work has been accomplished in this area.

However, data on the level of progesterone in normal pregnancy, and as it relates to a variety of pregnancy-related complications and features of previous reproductive history has been generated in a study which was conducted from the years through at the Pope Paul VI Institute. Modern means of progesterone assessment with improved accuracy and precision were used along with more precise means of dating the pregnancies.

In this study, patients through pregnancies and 8, progesterone levels were studied and statistically evaluated. These patients were primarily infertility patients who were receiving progesterone supplementation during the course of their pregnancy. Infertility was either primary or secondary and some of the patients also had a history of previous spontaneous abortion and, in some cases, recurrent spontaneous abortion.

The physician reader of this web site should consult that textbook for all of the details. A summary of the statistically significant changes in progesterone levels by condition or event is presented in Table It has also been thought that the placenta takes over the production of progesterone during the second and third trimesters of pregnancy. This study shows that the level of progesterone in first and second trimester spontaneous abortions, are indeed statistically decreased.

In fact, this observation supports the structure of the study conducted at the Pope Paul VI Institute. However, a decrease in progesterone production, presumably by the placenta, during the second and third trimester of pregnancy in a variety of different pregnancy-related complications and previous pregnancy historical events was also observed.

The endometrium of reproductive aged women undergoes cyclic developmental changes in preparation for implantation in response to estrogen and progesterone. These steroids and their receptors are tightly regulated throughout the menstrual cycle, and their actions are facilitated by the presence of steroid receptor coactivators of the p family.

In this study using immunohistochemistry and Western blot analysis, we characterize the expression patterns of three coactivators, steroid receptor coactivator-1, amplified in breast cancer-1 AIB1 , and transcriptional intermediary factor-2 in human endometrium obtained prospectively from normal fertile women throughout the menstrual cycle. With the exception of glandular AIB1, which increased in the late secretory phase, none of the coactivators changed significantly during the menstrual cycle.

Compared with both fertile and infertile controls, PCOS women exhibited elevated levels of AIB1 and transcriptional intermediary factor-2 expression in both epithelial and stromal cells.

Estrogen, or oestrogen, is the primary female sex is responsible for the development and regulation of the female reproductive system and secondary sex are three major endogenous estrogens in females that have estrogenic hormonal activity: estrone, estradiol, and estrane steroid estradiol is the most potent and prevalent of these.

First trimester ultrasound is performed in the first months of a pregnancy. Pregnancy ultrasounds are performed mainly using transabdominal ultrasound. For many women, especially after 8 weeks gestation, sufficient information about the baby may be obtained with transabdominal ultrasound only. However, in the early pregnancy, the developing embryo is very small at 6 weeks gestation, the baby is only mm long and a transvaginal ultrasound may be required to get a better image of the baby. Transvaginal ultrasound is safe and commonly performed during all stages of pregnancy, including the first trimester.

It will not harm you or your baby. Transabdominal ultrasound involves scanning through your lower abdomen. A small amount of ultrasound gel is put on the skin of the lower abdomen, with the ultrasound probe then scanning through this gel.
