Establishing pregnancy location is key to minimising the risks of abortion, and establishing gestational age optimises women's choice of procedure and timing. There is limited information in UK practice about the views of women having an ultrasound before an abortion with regards to whether they would wish to see the scan image of their fetus. We therefore surveyed the views of women having pre-abortion ultrasound scans and the views of ultrasonographers, using self-completed anonymous questionnaires. Responses were available for analysis from 191 women aged 16 to over 45. A total of 25 (13%) women had seen their scan. Of those who did not see their scan, 40 (24%) said they would have liked to see it, to aid their decision-making, as a right, or out of curiosity. Nine out of 17 ultrasonographers completed their questionnaires. Four ultrasonographers thought that women having scans before an abortion should see their scan images if they wished and another four thought they should not because of possible psychological effects. Their response also highlighted possible effects of such scans on those performing them. Given the choice, a larger number of women would like to see their scan images than actually ask. Women request to see their pre-abortion ultrasound images for their own individual reasons, which should be respected. Ultrasonographers may have conflict or ethical dilemmas when performing pre-abortion scans and they should be supported in identifying women for whom looking at their scan images would be of benefit.

BACKGROUND: The dual effects of insulin and androgen on the ovary act to promote early folliculogenesis. In the context of polycystic ovarian syndrome (PCOS), the presence of hyperinsulinaemia, resulting from increased insulin resistance (IR), and hyperandrogenaemia lead to the appearance of multiple antral follicles and frequently a multi-folliclular response to gonadotrophin stimulation for assisted reproductive treatments (ARTs). The effect of IR and androgen status in women without PCOS on the follicular outcome of controlled ovarian hyperstimulation (COH) is not known. [ABSTRACT FROM PUBLISHER]

Objectives: To evaluate the effects of long-term tibolone on the endometria of asymptomatic women over the age of 60 years. Methods: An observational study of the ultrasound appearance of the endometria of women aged 60 years or older taking long-term tibolone. Those found to have a double-layer endometrial thickness greater than 4 mm were offered endometrial biopsy. Results: Seventeen asymptomatic patients with a mean age of 61 years (range 60-73 years) and an average duration of tibolone use of 5 years (range 3-12 years) were recruited. Seven patients (41%) showed a thickened endometrium of more than 4 mm. Three of these had an area of translucency in the subendometrial space. Of the ten women with an endometrial thickness of less than 4 mm, four showed the presence of subendometrial fluid. Hysteroscopy was performed in five out of the seven women, as two did not accept further investigations. In all five women, the endometrial cavity was reported as atrophic and the histology showed an inactive basal type. In two of the five cases examined histologically, there were additional changes suggesting endometrial polyp, although the samples were from macroscopically non-polypoid endometrium. Discussion: Endometrial thickness is increased in 41% of elderly women on long-term treatment with tibolone. However, at hysteroscopy, the endometrium was uniformly atrophic. Similar finding have been described in women using selective estrogen receptor modulators and a similar mechanism of action of these drugs on the uterus should be considered. [ABSTRACT FROM AUTHOR]

Objectives: To compare carbohydrate metabolism, adrenal and thyroid function during use of a combined contraceptive vaginal ring (NuvaRing, NV Organon, Oss, The Netherlands) with those of a combined oral contraceptive.Methods: Healthy women aged 18-40 years used either the vaginal ring, delivering 15 microg ethinylestradiol and 120 microg of etonogestrel per day, or a combined oral contraceptive containing 30 microg ethinylestradiol and 150 microg levonorgestrel, for six cycles. Each cycle comprised 3 weeks of use of the ring or the pill followed by 1 ring- or pill-free week. The following parameters were measured at baseline and at the end of cycles 3 and 6: carbohydrate metabolism (glucose, insulin, glycosylated hemoglobin); adrenal function (total cortisol, cortisol binding globulin, dehydroepiandrosterone sulfate); thyroid function (thyroid stimulating hormone, free thyroxine).Results: Small and similar increases in insulin were seen in both groups. Concentrations of cortisol binding globulin and total cortisol rose significantly less during ring use than during combined oral contraceptive use (cycle 3, p= 0.0002; cycle 6, p < 0.0001). Levels of dehydroepiandrosterone sulfate did not change in either group. Thyroid stimulating hormone levels increased significantly more in the ring group at cycle 3 (p = 0.0016) but free thyroxine levels were unchanged in both groups.Conclusions: Both the vaginal ring and the oral contraceptive have no clinically relevant effects on carbohydrate metabolism, adrenal or thyroid function.

BACKGROUND: In January 2001, emergency hormonal contraception was made available for women over the age of 16 years directly from a pharmacist without prescription. It is of interest whether this change in the UK has led to any improvements or deterioration in the service provided for the women who need it. METHODS: Self‐ completed, anonymous questionnaires were distributed to women requesting emergency hormonal contraception through a single group of pharmacies located throughout England, Wales and Scotland. RESULTS: A total 419 women returned completed questionnaires. A greater proportion of women were able to take emergency contraception within 24 h when they obtained their tablets directly from a pharmacy without a prescription (64% versus 46%, P = 0.029). Women who obtained their drugs directly from the pharmacist were just as well informed, just as likely to arrange regular follow‐up and generally preferred this system, although they disliked having to pay. CONCLUSION: Making emergency hormonal contraception available without prescription has improved services to women who need them, but these improvements are quantitatively minimal, preventing only five additional pregnancies per 10 000 users.

Background: The effects of contraception on subsequent fecundity are yet to be substantiated.Methods: A total of 2841 consecutive pregnant women in Hull and Sheffield completed questionnaires inquiring about time to pregnancy (TTP), contraceptive use, pregnancy planning, previous pregnancies, age and lifestyle characteristics of each partner. Outcome measures were mean TTP, conception probability and odds of subfecundity after discontinuing each contraceptive method.Results: TTP following long-term combined oral contraceptive (COC), short-term intrauterine device (IUD) or any duration of injectable use were 2.0-, 1.6-, 3.0-fold longer than TTP after condom use, respectively. Within 6 months of discontinuing COC or injectable use, conception probabilities were 0.86 and 0.34, respectively, whereas those relevant to other methods were not significantly different. All levonorgestrel intrauterine system (IUS) users conceived within 1 month. Relative to condoms, odds of subfecundity after COC, injectable and short-term IUD use were 1.9, 5.5, 2.9, respectively. The effect of COC and injectables was stronger with long-term use, in older, obese or oligomenorrhoeic women. Similar results were obtained after adjustment for potential confounders.Conclusions: A significant reduction in fecundity occurs after COC, IUD or injectables, which is dependent on the duration of use. The effect of COC and injectables is evident in women with a potentially compromised ovarian function. Use of progesterone-only pills or IUS is not associated with a significant effect.

Objective The endometrium in women on tamoxifen is often made irregular by small cysts. The aim of this study was to assess the accuracy and precision of the measurement of endometrial depth by transvaginal sonography. Methods The endometrial depth from endometrial biopsies obtained with the resectoscope in 15 women receiving tamoxifen was compared to the endometrial depth measured by TVS. The inter-observer variability was measured in 58 women. Results In those biopsies of sufficient quality to allow a measurement, the corresponding depth measurement obtained by ultrasound was up to 3 mm greater than the histological measurement. The interobserver variability for the measurement of endometrial depth using TVS was assessed in 58 postmenopausal women on tamoxifen. The interobserver variability deteriorated as the mean endometrial depth increased, probably because the increase in depth resulted from greater morphological changes within the endometrium such as cyst formation which resulted in an irregular endometrial/myometrial boundary. This may, however, be improved by performing saline instillation sonography. In a prospective study of 10 postmenopausal women, the interobserver variability was significantly greater during tamoxifen treatment compared to pretreatment. Conclusions On the basis of the above, if uterine surveillance using TVS were to be offered to postmenopausal women on tamoxifen, then the procedure should be augmented by saline instillation sonography if the endometrial depth is > 4 mm, as this will improve the measurement precision and also identify intrauterine pathology.

Endocrine and ultrasound effects were studied of an intermittent (every 28 days) oral administration of 150 mg of the anti-progestagen Org 31710 during the continued daily use of 75 microg desogestrel (DSG) for progestagen-only contraception. A randomized, double-blind, placebo-controlled two-centre study was conducted in 50 healthy volunteers. Serum luteinizing hormone (LH), follicle stimulating hormone (FSH), oestradiol and progesterone concentrations, and follicle number and size were studied, as well as endometrial thickness, which was assessed by transvaginal sonography at least twice weekly during a single medication cycle (cycle 3-5). Forty-eight women were evaluated (Org 31710, n = 25; placebo, n = 23). Seven ovulations were observed in the treated group versus none in the placebo group. LH concentrations were higher on days 9 and 11 and oestradiol concentrations lower on day 3 in the treated group, irrespective of whether ovulation occurred. No parameter could predict ovulation. Endometrial thickness was greater on cycle days 7-13 and 19 in the treated group. However, within the Org 31710 group, no significant differences were found in volunteers who did or did not ovulate. Observed differences may be attributed to a competitive effect of Org 31710 with progestagen-induced suppression of the pituitary-ovarian axis, altered oestradiol feedback mechanisms, and/or altered receptor availability.

Objective: This study aimed to investigate the histology of the subendometrial halo, the junctional zone between the endometrium and myometrium. Methods: Thirteen ex vivo uteri removed for treatment of menorrhagia were studied. In each case, the subendometrial halo, as seen by transvaginal ultrasound, was marked using a Nottingham breast location biopsy needle. A standard histological examination was performed. Full thickness blocks of the anterior uterine wall were taken and standard serial 5-micron tissue sections were prepared from each block. Subsequent morphometric analysis followed staining with Feulgen reagent, using a CAS 200D quantitative image analysis system. Additionally, anti-CD31, an antibody stain for vascular endothelium, was used. Results: The histological examination showed the subendometrial halo to consist of apparently normal myometrium. Morphometric analysis demonstrated a greater total nuclear area in the subendometrial halo than the outer myometrium, but no difference in individual nuclear size between the two zones. CD31 stained a greater total area in the inner myometrium. Conclusions: These results suggest that the subendometrial halo is a distinct compartment of the myometrium comprising tightly packed muscle cells with an increased vascularity. Such architecture would increase the density of this tissue layer, altering its acoustic impedance, and account for its echopenic appearance on ultrasound. [ABSTRACT FROM AUTHOR]

The most informative method for assessing tubal patency in subfertile women is laparoscopy-and-dye. This investigation, however, puts a large burden on services and a screening test is needed that identifies a high likelihood of occlusion. In our infertility programme we introduced hysterosalpingo contrast sonography for this purpose, operated entirely by ultrasonographers. A series of audits indicated that this innovation speeded the process of investigation by several weeks and reduced the number of laparoscopy-and-dye procedures by 75%. The negative predictive value was 89% and the positive predictive value was 44%. The main limitation of the method was the long period required for training, in those without extensive experience of vaginal ultrasonography. [ABSTRACT FROM AUTHOR]
