Its cyclic structural changes mirror changes in metabolic functions, and both are regulated by ovarian estradiol and progesterone. Because of this interplay of structure, function, and ovarian hormonal stimuli, the endometrium is considered one of the most sensitive indicators of the hypothalamic-pituitary-ovarian hormonal axis. As a result, morphologic evaluation of the endometrium is used in diagnostic evaluation of infertile patients to determine whether ovulation is occurring Fig. Schematic representation of steroid hormone-morphologic interactions during the endometrial cycle. Estradiol promotes endometrial proliferation, whereas after ovulation, progesterone converts estradiol-primed endometrium into secretory tissue. Postovulatory estradiol amplifies the progesterone effect, and after withdrawal of both estradiol and progesterone, the endometrial mucosa breaks down and regenerates within the period of menstruation. These steroid receptors are specific proteins concentrated exclusively in the nuclei of both endometrial epithelial and stromal cells, as well as the endothelial cells of stromal capillaries. They have high affinity to bind estradiol and progesterone, respectively. This chapter contains a review of the technical procedures for handling endometrial tissues and a discussion of the morphologic aspects of the endometrium, focusing on the interpretation and understanding of the physiomorphology of the endometrial cycle.

The staging of human endometrium following the Noyes criteria (Noyes et al., ) is a subjective system that has been scrutinized in recent years because of its inaccuracies in properly dating.

Nature versus nurture Certain characteristics may be innate in humans; these characteristics may be modified by the physical and social environment in which people interact. The sexual drive affects the development of personal identity and social activities. Freud believed sexual drives are instinctive. He was a firm supporter of the nature argument; he said there are a large number of instincts but they are reduced into two broad groups: Eros the life instinct , which comprises the self-preserving and erotic instincts, and Thanatos the death instinct , which comprises instincts invoking aggression, self-destruction, and cruelty.

His instinct theory said humans are driven from birth by the desire to acquire and enhance bodily pleasures, thus supporting the nature debate. Freud redefined the term sexuality to make it cover any form of pleasure that can be derived from the human body. His developmentalist perspective was governed by inner forces, especially biological drives and maturation, and his view that humans are biologically inclined to seek sexual gratification demonstrates the nature side of the debate.

Later, behaviorists would apply this notion in support of the idea that the environment is where one develops one’s sexual drives. A number of them, including neo-analytic theories, sociobiological theories, social learning theory , social role theory , and script theory , agree in predicting that men should be more approving of casual sex sex happening outside a stable, committed relationship such as marriage and should also be more promiscuous have a higher number of sexual partners than women.

These theories are mostly consistent with observed differences in males’ and females’ attitudes toward casual sex before marriage in the United States; other aspects of human sexuality, such as sexual satisfaction, incidence of oral sex , and attitudes toward homosexuality and masturbation , show little to no observed difference between males and females.

Transvaginal ultrasonography and female infertility

Thus, estradiol produces breast development , and is responsible for changes in the body shape , affecting bones, joints, and fat deposition. It enhances growth of the myometrium. Estradiol appears necessary to maintain oocytes in the ovary. During the menstrual cycle , estradiol produced by the growing follicles triggers, via a positive feedback system, the hypothalamic-pituitary events that lead to the luteinizing hormone surge, inducing ovulation.

In the luteal phase, estradiol, in conjunction with progesterone , prepares the endometrium for implantation. During pregnancy , estradiol increases due to placental production.

Sie werden durch die hormonale Regulierung des Eisprungs Ovulation gesteuert. Diese findet auf drei Ebenen statt: Hypothalamus – Hypophyse – Eierstock. Man unterscheidet zwei Haupthormone, die auf das Endometrium einwirken: Die Zeit vor dem Eisprung nennt man Proliferationsphase , die 14 darauf folgenden Tage bezeichnet man als Sekretionsphase. So wird die Schleimhaut auf die Implantation vorbereitet.

Bei Primaten setzt sich das Endometrium aus einer oberen Funktionalis und einer unteren Zellschicht Basalis zusammen. Bleibt eine Implantation aus, wird die Funktionalis des Endometriums bei Primaten abgesondert und ausgeschieden: Es kommt zur Regelblutung Menstruation. Daher wird die Funktionalis in Vorbereitung auf die Menstruation auch Dezidua lat.

Kommt es dagegen zur Einnistung einer befruchteten Eizelle und damit zu einer Schwangerschaft, erfolgen weitreichende hormonell gesteuerte Modifikationen des Endometriums, das nunmehr Dezidua graviditatis genannt wird. Sie bildet zusammen mit dem Chorion die Plazenta aus.

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.

And for your enjoyment I cannot examine every claim that my correspondents share with me.

Sometimes the independent thinkers prove to be correct, and paradigms shift as a result. You also know that extraordinary claims require extraordinary evidence. When a discovery proves to square with the observable world, scientists make reputations by confirming it, and corporations are soon making profits from it. When a decades-old claim by a “persecuted genius” finds no acceptance from mainstream science, it probably failed some basic experimental tests designed to eliminate self-deception.

If you ask me about something like this, I will simply invite you to do some tests yourself, perhaps as a high-school science project.

Background Fluorescein angiography allows visualization of blood flow in retinal and choroidal tissues, permitting diagnostic support in many ocular diseases. In particular, fluorescein angiography has become a very important tool in the diagnosis and treatment of chorio-retinal diseases. However, limitations of fluorescein angiography in imaging the choroidal circulation and associated pathologies prompted the use of alternative dyes to improve choroidal angiography. Indocyanine green angiography is a diagnostic study where indocyanine green, a fluorescent dye, is injected intravenously, and observations of the retina are made at intervals as increasing intensity of retinal and choroidal circulation is displayed.

Indocyanine green angiography is used for the imaging of retinal and choroidal vasculatures. It is effective when used as an adjunct to fluorescein angiography in the diagnosis and treatment of ill-defined choroidal neovascularization i. It is generally used in evaluating retinal neovascularization, serous detachment of retinal pigment epithelium, hemorrhagic detachment of retinal pigment epithelium, and retinal hemorrhage.

In dating the endometrium it is important to remember that there is a delay of 2–3 days between ovulation and appearance o f diagnostic postovulatory histologic changes. This is caused by progressively rising progesterone levels and time necessary for the endometrium to respond.

Adapted from Witkin et al. Unsuspected Chlamydia trachomatis infection and in vitro fertilization outcome. Am J Obstet Gynecol Nongonococcal-nonchlamydial salpingitis may also arise de novo as a primary infection. There is less fever, vaginal discharge, and liver tenderness than with gonococcal PID. Despite these differences, the clinical presentation does not adequately distinguish between the two, and reliance on culture is necessary.

Except for the presence of N. As shown in Table 1 , the cervix and vagina of healthy women contain an abundance of aerobic and anaerobic microorganisms. There may be a critical number of organisms needed to overwhelm local host defense mechanisms in the cervix, allowing an infection to ascend to the upper genital tract. There is probably a continuum from bacterial vaginosis to endometritis and salpingitis, because women with bacterial vaginosis are significantly more likely to be diagnosed with PID.

Previous gonorrhea, use of an IUD, frequent douching, and uterine instrumentation predispose to the development of nongonococcal PID.

Pathology Outlines

Transvaginal ultrasound is performed using a special transducer which is slightly thicker than a tampon. It is covered with a disposable latex sheath and lubricating gel, then gently placed into the vagina. The probe sits in the vagina throughout the examination which usually takes between minutes. Most patients find the examination much more tolerable when compared to a cervical PAP smear. During the scan the sonographer may need to gently press on the abdomen to move bowel out of the way and bring the ovaries and other pelvic structures into view.

Pelvic / Gynaecologic Ultrasound

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.

A small amount of ultrasound gel is put on the skin of the lower abdomen, with the ultrasound probe then scanning through this gel.

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.

The DHB says a national programme designed to improve prescribing during the first post-graduate year is also being developed. The programme will involve a compulsory assessment of prescribing competency. For example, a year-old Illinois man with episodes of low cost phentermine Care Chemist spokesperson and Orewa pharmacist Antony Wentworth says paracetamol is listed by the National Poisons Centre as the most common substance in the poisoning of children under five, accounting for abut 65 per cent of its calls.

The endometrial biopsy has been used to assess endometrial histology for the last 60 to 70 years. While sampling the endometrium is used extensively in the setting of abnormal bleeding as a diagnostic tool for endometrial cancer or hyperplasia, its primary role in the evaluation of the infertile couple was assessment of the luteal phase.

The American Society of Reproductive Medicine has formulated diagnostic criteria for minimal to severe endometriosis to aid in standardized description of the types and locations of implants and associated scar tissue. Pelvic pain may occur in women with minimal to severe disease; however, pain cannot be used to predict the amount or location of endometriosis implants.

Severe pain may be present with minimal endometriosis and minimal or no pain may coexist with severe endometriosis. Only large implants on the ovaries that develop into endometriomas can be visualized reliably with ultrasonography. Fertility potential is impaired when endometriosis distorts the oviducts and ovaries. However, the mechanisms by which endometriosis might lead to infertility are unclear. Minimal endometriosis does not involve either oviducts or ovaries.
