Free cells of the connective tissue Fig. More info Vascular mechanisms basic to menstruation The mechanisms that regulate the menstruation phase 1rst-4th day result from the reduction in the estrogen and progesterone values, leading to a constriction of spiral arteries and consequent necrosis of the tissue. Only the functional layer of the endometrium is affected by these cyclic changes – the basal layer remains intact. The uterine vessel network scheme exhibits a selective sensibility with regard to the cyclic hormonal alterations. The radial and basal arterioles do not react to the hormonal variations, whereas the spiral arteries of the functional layer are hormone sensitive and constrict when the progesterone concentration decreases. Together with blood, which does not coagulate due to a local fibrinolytic factor, the necrotic tissue is eliminated menstruation. The follicular or proliferative phase During the proliferative or follicular phase 4th to 14th day the secretion of estrogen through the growing ovarian follicle is responsible for the proliferation of the endometrium intensive mitosis in the glandular epithelium and in the stroma. The uterus epithelium clothes the surface again.

Endometrial biopsy The best way to prove or disprove that ovulation has taken place is to take an endometrial sample on cycle day 22 or later, preferably at the onset of uterine bleeding. By obtaining samples at the time of early uterine bleeding, the pathologist will be able to determine whether the bleeding is caused by the breakdown of post-ovulatory, secretory endometrium; by focal necrosis of the endometrium associated with anovulation; by other pathologic states; or by hormone administration.

Also, during the period of bleeding, both the external os and the isthmus lower uterine segment are widened, facilitating penetration of the biopsy forceps into the endometrial cavity. The final argument in favor of taking samples at the onset of bleeding is that endometrium of the first 2 days of menstruation is relatively easy to recognize histologically. In contrast, secretory-phase endometrium often demonstrates subtle changes and, in many cases, combinations of morphologic changes, resulting in most instances in errors of 4—5 days.

The pathologist can improve this to 2—3 days, however, by acquiring expertise in endometrial dating all cases of normal endometria are to be dated regardless of reasons for sampling , and by basing the dating on those endometrial morphologic alterations that represent the most advanced phase of the menstrual cycle.

Endometrial biopsies are not to be taken at the onset of bleeding in the following two conditions: These changes are presumably due to the poor development of the corpus luteum. According to most investigators, measurements of serum progesterone levels rather than histological dating of the endometrium provide for the best assessment of LPD see discussion later in this chapter.

In LPD, circulating progesterone levels are decreased and not sufficient to promote full secretory differentiation of the endometrium.

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. Oral contraceptives may decrease the risk of developing PID, although they have less protective effect than barrier contraceptives. It is logical that women who have used IUDs suffer more tubal infertility and that women who used oral contraceptives have less infertility than women who have used neither method.

The introduction of water-soluble contrast media has eliminated the complications of oil embolism and has reduced the risk of granuloma formation, but inflammatory reactions continue to be serious complications of this procedure.

Long term effects of IUD on the human endometrium. Histologic, histochemical and ultrastructural studies. To evaluate the longterm effects of a IUD on the human endometrium and find the possible contraceptive mechanism of the IUD, histologic, histochemical, and ultrastructural studies of human endometrial biopsies from 44 normal contorls and IUD wearers were made.

Endometrial biopsy slides randomly selected from a multicenter study testing the utility of biopsy in the diagnosis of infertility were distributed to three gynecologic pathologists, who estimated cycle day using standard criteria. Readers were blinded to the purpose of the study, patient age, fertility status, or timing of biopsy relative to LH surge or next menses. Multicenter academic research programs in reproductive medicine. Eighty-two women with proven fertility, 83 infertile patients.

Harms Based on solid evidence, screening asymptomatic women will result in unnecessary additional biopsies because of false-positive test results. Risks associated with false-positive tests include anxiety and complications from biopsies.

Evidence obtained from cohort studies. One study for endometrial biopsy and one study for hysteroscopy. Magnitude of Effects on Health Outcomes:

The results provide a normative curve with 95% confidence limits for serum PEP concentrations vs normalized cycle day in women with adequate endometrium (judged by histologic endometrial dating), and indicate that the PEP concentration increases exponentially after day 22, with a mean doubling time of (mean±SD) days (based on serial.
