RESUMO

OBJECTIVE: To compare the extent to which visceral adiposity, as measured by mesenteric fat thickness, contribute to cardiometabolic risk, especially insulin resistance, in women with PCOS and healthy control. METHODS: This is a cross-sectional study with a total of 190 women with PCOS fulfilling the Rotterdam diagnostic criteria. Women without PCOS were recruited from a previous study, which comprised 416 healthy women controls with normal glucose tolerance. All subjects underwent OGTT, biochemical assessment, and sonographic assessment with measurements of mesenteric, preperitoneal and subcutaneous fat thickness. RESULTS: Mesenteric fat thickness was strongly correlated to cardiometabolic traits including blood pressure, fasting and 2-h glucose, triglycerides, HOMA-IR; and was negatively correlated to HDL-C in both cohorts (all p < 0.01). In PCOS, positive correlation was observed between mesenteric fat thickness and free androgen index (p < 0.01). Compared with controls, the regression line between mesenteric fat and HOMA-IR is much steeper in PCOS (p < 0.01). CONCLUSION: Women with PCOS remain more insulin resistant compared to controls at any given degree of visceral adiposity.

RESUMO

Embryos have traditionally been thought to implant at the exact site they are transferred during assisted reproductive technology (ART). The introduction of 2D/3D ultrasound has allowed for mapping of the transfer site using air bubbles as a surrogate marker of embryo location. This study's aim was to compare the location of embryo transfer (ET) on ultrasound to that of embryo implantation. We present four cases of ectopic pregnancy at four sites: tubal, cervical, interstitial and ovarian. We compare the site of implantation on 2D/3D ultrasound at six weeks of pregnancy to that of transfer as assessed on 2D/3D ultrasound. In all four cases, the embryo flash was visualised in the centre of the uterine cavity on ultrasound at ET. At six weeks of pregnancy, the uterine cavity was empty and an ectopic pregnancy was identified. The tubal and ovarian ectopics were managed surgically whilst the cervical and interstitial pregnancies were treated with systemic methotrexate. These cases demonstrate embryo implantation distal to the ultrasound-confirmed site of transfer. These cases provide visually compelling evidence of embryo migration following ET and lend support to the theory that ectopic pregnancy may occur as a result of embryo migration, rather than poor ET technique.

RESUMO

OBJECTIVE: To determine the relationship between the presence of detectable HBV DNA in the follicular fluid in HBV carriers with IVF/ICSI treatment outcome. STUDY DESIGN: A prospective observational study conducted in the Assisted Reproductive Unit, a tertiary referral centre affiliated with the Department of Obstetrics and Gynecology, The Chinese University of Hong Kong; and the Union Reproductive Medicine Centre at Union Hospital, Hong Kong. The primary outcome measure was pregnancy rate. Secondary outcome measures were the prevalence of detectable HBV DNA in the follicular fluid, implantation rate, clinical pregnancy rate, ongoing pregnancy rate and live birth rate. RESULTS: HBV DNA was detected in the follicular fluid of 28 (43.8%) of the 64 women, and the mean level in this group in log10 copies/mL (±SD) was 4.36 ± 1.85. Women with detectable follicular fluid HBV DNA were younger, lighter, had longer duration of infertility, higher incidence of detectable serum HBV DNA (OR 4.592, 95% C I 2.333-9.038), and significantly wider range in the number of total fertilized, viable embryos, and blastocyst rate, but no difference in cycle characteristics, stimulation and pregnancy outcomes, although the almost doubled ongoing pregnancy/live birth rate per cycle initiated (60.7% versus 38.9%) failed to reach statistical significance due to the small numbers. CONCLUSION: Our results suggested HBV infection did not appear to be detrimental to the outcome of IVF/ICSI treatment.

RESUMO

Polycystic ovary syndrome is the most common endocrine disorder among women of reproductive age. Although traditionally viewed as a reproductive disorder, there is increasing appreciation that it is associated with significantly increased risk of cardiometabolic disorders. Women with polycystic ovary syndrome may present to clinicians via a variety of different routes and symptoms. Although the impact on reproduction predominates during the reproductive years, the increased cardiometabolic problems are likely to become more important at later stages of the life course. Women with polycystic ovary syndrome have an approximately 2- to 5-fold increased risk of dysglycaemia or type 2 diabetes, and hence regular screening with oral glucose tolerance test is warranted. Although the diagnostic criteria for polycystic ovary syndrome are still evolving and are undergoing revision, the diagnosis is increasingly focused on the presence of hyperandrogenism, with the significance of polycystic ovarian morphology in the absence of associated hyperandrogenism or anovulation remaining uncertain. The management of women with polycystic ovary syndrome should focus on the specific needs of the individual, and may change according to different stages of the life course. In view of the clinical manifestations of the condition, there is recent debate about whether the current name is misleading, and whether the condition should be renamed as metabolic reproductive syndrome.

RESUMO

OBJECTIVE: To compare the effects of laparoscopic ovarian drilling in treating infertile polycystic ovarian syndrome in patients with and without metabolic syndrome. DESIGN: Retrospective review. SETTING: A university-affiliated hospital in Hong Kong. PATIENTS: A total of 89 infertile anovulatory polycystic ovarian syndrome patients, who underwent laparoscopic ovarian drilling with completed metabolic screening and seen over a 5-year period from 2002 to 2007. MAIN OUTCOME MEASURES: The clinical, hormonal, and metabolic characteristics as well as spontaneous ovulation rates, reproductive outcomes, and diabetes risks during pregnancy observed after laparoscopic ovarian drilling. RESULTS: Approximately one fifth (21%) of polycystic ovarian syndrome patients had the metabolic syndrome. There were no differences in spontaneous ovulation rates (68% vs 61%, P=0.76), cumulative pregnancy rates (68% vs 61%, P=0.77), and diabetes risks during pregnancy (64% vs 42%, P=0.13) between patients with and without metabolic syndrome. CONCLUSION: Laparoscopic ovarian drilling was equally effective in inducing ovulation in polycystic ovarian syndrome patients with metabolic syndrome. Thus, patients with metabolic syndrome should not be precluded from laparoscopic ovarian drilling, which has the additional advantage of enabling full tubo-peritoneal assessment at the same time.

RESUMO

OBJECTIVE: Visceral fat is believed to be important in the pathogenesis of metabolic syndrome and fatty liver. In this study, we examined the relationship between mesenteric fat thickness and other sonographic indices of adiposity and the presence of fatty liver among subjects with polycystic ovary syndrome (PCOS). SUBJECTS AND METHODS: A total of 117 Chinese subjects with PCOS were evaluated (mean age, 28.6 ± 6.5 yr; mean body mass index, 24.3 ± 5.3 kg/m(2)). Anthropometric measurements and metabolic risk profile, including a standard oral glucose tolerance test, were assessed in all subjects. All subjects underwent an ultrasound examination for measurement of thickness of mesenteric, preperitoneal, and sc fat as well as evaluation for fatty liver. RESULTS: Forty-six (39.3%) of the subjects had fatty liver. PCOS subjects with fatty liver had higher body mass index, waist circumference, waist-hip ratio, and systolic blood pressure; a more unfavorable lipid profile with higher triglyceride; lower high-density lipoprotein cholesterol; higher fasting glucose and insulin; higher 2-h glucose during oral glucose tolerance test; lower SHBG; and higher alanine aminotransferase. Subjects with fatty liver had increased thickness of preperitoneal, mesenteric, and sc fat, as well as increased carotid intima-media thickness. Abdominal fat thickness showed moderate correlation to alanine aminotransferase as well as fasting insulin. On multivariate logistic regression, fasting insulin and mesenteric fat thickness were identified as independent predictors of fatty liver among subjects with PCOS. CONCLUSION: Fatty liver is present in a significant proportion of Chinese patients with PCOS. Sonographic measurement of mesenteric fat is an independent determinant of fatty liver among subjects with PCOS and identifies subjects at increased cardiovascular risk.

RESUMO

BACKGROUND: Women with polycystic ovary syndrome (PCOS) frequently exhibit central obesity, glucose intolerance, atherogenic dyslipidaemia and hypertension which are characteristic features of the metabolic syndrome (MetS). METHODS: A total of 295 premenopausal Chinese women with PCOS diagnosed by the Rotterdam criteria (mean age: 30.2 +/- 6.4 years) and 98 control subjects without PCOS were evaluated for prevalence of MetS and cardiovascular risk factors, including dyslipidaemia and dysglycaemia. RESULTS: Using the 2005 modified Adult Treatment Panel III criteria, MetS (presence of three or more risk factors) was found in 24.9% of PCOS women compared to 3.1% of controls. The prevalence of MetS in PCOS women increased from 16.7% at under 30 years of age to 53.3% at over 40 years. MetS was also more prevalent in overweight and obese (41.3%) than normal-weight PCOS women (0.9%). However, multivariate regression analysis showed that women with PCOS had a 5-fold increase in risk of MetS (odds ratio 4.90; 95% confidence interval: 1.35-17.84) compared with women without PCOS even after controlling for age and BMI, suggesting PCOS alone is an independent risk factor for MetS. CONCLUSIONS: There is high prevalence of MetS in Hong Kong Chinese women with PCOS despite their relatively young age. Recognition of these cardiometabolic risk factors requires a high level of awareness in conjunction with early and regular screening.

RESUMO

OBJECTIVES: To identify the characteristics of Hong Kong Chinese women with polycystic ovarian syndrome and to compare different diagnostic criteria. DESIGN: Retrospective study. SETTING: Gynae-endocrinology Clinics in the Prince of Wales Hospital, Hong Kong. PATIENTS: Ninety Hong Kong Chinese women with polycystic ovarian syndrome who were diagnosed according to the hospital's criteria. MAIN OUTCOME MEASURES: Prevalence of typical features of polycystic ovarian syndrome, including anovulation and hyperandrogenism (with other endocrine causes excluded), polycystic ovarian features on ultrasonography, luteinising hormone predominance, obesity, and insulin resistance. RESULTS: Almost all (98.9%) patients with polycystic ovarian syndrome presented with anovulation, only 48.9% of them had clinical or biochemical evidence of hyperandrogenism. Typical ultrasound appearances of polycystic ovaries were observed in 86.7% of patients. Luteinising hormone predominance and insulin resistance were demonstrated in 67.8% and 40.7% of the cohort, respectively. Eight-six (95.6%) patients should have also been diagnosed with polycystic ovarian syndrome based on the 2003 Rotterdam new criteria. About 60% of patients who screened positive for insulin resistance had normal fasting serum glucose levels. The same proportion who had full screening for insulin resistance by oral glucose tolerance tests and fasting serum glucose to insulin ratios had discordant results of these two tests. CONCLUSIONS: The 2003 Rotterdam new diagnostic criteria for polycystic ovarian syndrome are generally applicable to the Hong Kong Chinese population. Early detection of insulin resistance in patients with polycystic ovarian syndrome can be ensured by performing an oral glucose tolerance test combined with measurement of fasting serum glucose to insulin ratio.

RESUMO

Polycystic ovary syndrome (PCOS) is a common endocrinopathy in women; its traditional pharmacological therapy mainly addresses short-term symptom control and does not correct the associated long-term metabolic risks. Recently, there has been increasing evidence that insulin resistance has an important implication in the pathogenesis of PCOS and that insulin-sensitizing drugs are a useful therapeutic approach. Therefore this review aims to discuss the current evidence on the use of metformin, a commonly used insulin-sensitizing agent, in treating both the short-term and the long-term problems of women with PCOS.

RESUMO

BACKGROUND: Hydrosalpinx fluid may be toxic to sperm and early embryo growth. Information concerning the effect of hydrosalpinx fluid on embryo development during organogenesis is lacking. METHODS: Rat embryos at gestational day 9.5 were cultured for 48 h with 80% rat serum and 20% of either hydrosalpinx fluid (study group) or lactated Ringer's solution (control group). Embryos were scored for growth and development at the end of the culture period. RESULTS: Hydrosalpinx fluid, collected from 10 patients, was tested for embryotoxicity individually. Median total morphological scores were significantly lower in embryos exposed to hydrosalpinx fluid from three of the 10 patients (43.0 versus 47.0, P = 0.01; 36.0 versus 45.0, P < 0.001; 36.0 versus 46.5, P = 0.003). This was accompanied by a significant reduction in median yolk sac diameter (4.0 versus 5.2 mm, P < 0.001 and 4.0 versus 5.0 mm, P < 0.001) and somite number (17.5 versus 22.5, P < 0.001 and 17.0 versus 21.5, P = 0.008) in the latter two patients. CONCLUSIONS: Hydrosalpinx fluid in some patients may contain toxin(s) that is potentially teratogenic.

RESUMO

OBJECTIVE: To compare blood mercury concentrations of infertile couples with those of fertile couples in Hong Kong, and to examine the relationship between blood mercury concentrations and seafood consumption. DESIGN: Case-control study. SETTING: In vitro fertilisation (IVF) Unit and Antenatal Unit of a university teaching hospital. Sample One hundred fifty-seven infertile couples attending IVF treatment and 26 fertile couples attending antenatal care without known occupational exposure to mercury. METHODS: Mercury concentrations in whole blood were measured by cold vapour atomic absorption spectrophotometry. A dietitian recorded the quantity of seafood consumption among infertile couples via a food-frequency questionnaire. Blood mercury concentrations and quantity of seafood consumption were compared between infertile and fertile couples. MAIN OUTCOME MEASURES: Whole blood mercury concentrations, quantity of seafood consumption. RESULTS: Infertile couples had higher blood mercury concentrations than fertile couples. 'Infertile males with abnormal semen' and 'infertile females with unexplained infertility' also had higher blood mercury concentrations than their fertile counterparts. Blood mercury concentrations were positively correlated with quantity of seafood consumption. Infertile subjects with elevated blood mercury concentrations consumed a larger amount of seafood. CONCLUSION: Higher blood mercury concentration is associated with male and female infertility. Higher seafood consumption is associated with elevated blood mercury concentrations in our infertile population.

RESUMO

BACKGROUND: This open label study compared the effectiveness of patient-controlled sedation (PCS), with physician-administered sedation (PAS) during transvaginal ultrasound-guided oocyte retrieval (TUGOR). METHODS: A total of 106 patients was randomized using a computer model to receive either PCS (n = 51) or PAS (n = 55). Intra-operative sedation and co-operation were measured on a 5-point scale while severity of pain, and doctor and patient satisfaction were assessed using a 100 mm visual analogue scale. Number of oocytes retrieved and fertilization, cleavage and clinical pregnancy rates were also recorded. RESULTS: Levels of sedation and co-operation were similar between groups. The pain score was higher in the PCS group during (mean +/- SD, 53 +/- 23 versus 35 +/- 24; P < 0.01) and 2 h after the procedure (29 +/- 27 versus 17 +/- 22; P < 0.05). Doctors were less satisfied with PCS than PAS (62 +/- 25 versus 71 +/- 26; P < 0.05) while patients were highly satisfied with both methods (76 +/- 23 versus 74 +/- 21; not significant). There were no oversedation or peri-operative complications. Fertility outcomes were similar. Patients tended to prefer PCS when given the choice of sedation method. CONCLUSION: Although PCS provides less analgesia then PAS during TUGOR, it is safe, satisfactory and accepted by patients.

RESUMO

BACKGROUND: The follicular microenvironment is an important determinant of oocyte development. The aim of this study was to examine whether the myo-inositol (MI) content in human follicular fluid (FF) was associated with better oocyte quality. METHODS: A total of 53 patients treated with IVF was recruited to a prospective observational study. FF and serum samples collected were divided into two groups: group A consisted of FF associated with matured and fertilized oocytes, whilst group B was from follicles with immature and unfertilized oocytes. RESULTS: Patient's age, total ampoules of HMG used, days of stimulation, basal levels of FSH, estradiol (E(2)) levels on the day of HCG, and serum MI content were not significantly different between the two groups. FF volume and its MI content were significantly higher in group A compared with group B (P < 0.05). The levels of MI in FF were positively correlated with the amount of E(2) in their corresponding FF samples and also correlated with embryo quality. CONCLUSIONS: We propose that higher concentrations of MI and E(2) in human FF appear to play a role in follicular maturity and provide a marker of good quality oocytes.

RESUMO

Gonadotropin releasing hormone agonists (GnRHa) are commonly used during in vitro fertilization and embryo transfer (IVF/ET) treatment cycles to downregulate the hypothalamic-pituitary-ovarian axis prior to ovarian stimulation with gonadotropins. It has been suggested that profound downregulation may have an adverse effect on IVF/ET outcome. The aim of this study was to examine the relationship between the degree of downregulation and IVF/ET outcome. A retrospective analysis was performed on 151 IVF/ET cycles conducted over a six month period. Intensity of downregulation was assessed using measurements of serum concentrations of luteinizing hormone (LH) and estradiol (E2) made at the end of a two week downregulation period. There was no correlation between serum concentration of LH (whether used alone or in combination with E2) and IVF/ET pregnancy rates. However, those subjects who were more suppressed according to the E2 concentration (< 148 pmol/l, [median]) required significantly more gonadotropins (3306 IU versus 2863 IU, p < 0.05) and took longer for follicles to reach maturity (10.9 days versus 9.7 days, p < 0.05). They also had a lower pregnancy rate per embryo transfer (10.4% versus 28.6%, p < 0.05) compared with those having a higher basal E2 concentration. We conclude from this study that the basal serum E2 concentration rather than the LH concentration is a more sensitive indicator of the intensity of downregulation by GnRHa and it may be a better predictor of IVF outcome.

RESUMO

OBJECTIVE: The purpose of this study was to compare the psychologic impact and client satisfaction of routine surgical evacuation of the uterus with medical evacuation in cases of spontaneous abortion. STUDY DESIGN: This was a prospective, randomized controlled trial. Two hundred eighteen women who were admitted to a university teaching hospital after spontaneous abortion and who consented to the study were randomized to routine surgical evacuation or medical evacuation of the uterus with the use of misoprostol. General psychologic well-being, level of depression, fatigue symptoms, psychiatric morbidity, social functioning, client satisfaction, and acceptance were measured in the 2 groups. RESULTS: The 2 groups did not differ in any of the measured psychological outcomes. Significantly more participants who experienced successful evacuation of the uterus with the misoprostol protocol would choose the same mode of treatment if they were able to choose again. However, participants for whom the medical treatment failed to evacuate the uterus and subsequent surgical evacuation was required are significantly less satisfied with the treatment. CONCLUSION: Medical treatment of spontaneous abortion with misoprostol is psychologically safe and more compatible with the ethnomedical beliefs of our Chinese participants. Client satisfaction and acceptance should be taken into consideration in the evaluation of treatment outcomes.

RESUMO

PURPOSE: To evaluate the effects of follicular fluid and platelet-activating factor on sperm motion characteristics of cryopreserved oligospermic and normospermic samples. METHODS: Sperm motion characteristics were evaluated prior to cryopreservation, immediately after thawing and following incubation in human tubal fluid, follicular fluid, or 1-microM platelet-activating factor cultures. Sixteen oligospermic samples and 20 normospermic samples were examined. Sperm motion characteristics were analyzed manually according to WHO criteria (1999) and also with an automated videomicrography system. RESULT(S): Incubation in follicular fluid increased overall motility and the percentage of sperm with fast progressive motility in normospermic but not oligospermic samples. Incubation with platelet-activating factor increased overall motility and the percentage of sperm showing nonprogressive motility in both oligospermic and normospermic samples. CONCLUSION(S): The stimulatory effects of culture in follicular fluid as seen in normospermic samples do not show a significant benefit in oligospermic cryopreserved samples. Platelet-activating factor and follicular fluid increase motility via different mechanisms. Incubation of oligospermic cryopreserved sperm with PAF increases the number of motile sperm, thereby enabling easier identification of viable sperm for intracytoplasmic sperm injection in samples with severe asthenozoospermia.

RESUMO

OBJECTIVE: To examine changes in oviductin mRNA expression in oviductal mucosal tissue from fertile women throughout an ovulatory cycle. DESIGN: Semiquantitative reverse-transcriptase-polymerase chain reaction (RT-PCR) analysis of oviductin mRNA. SETTING: University-based obstetrics and gynecology department. SUBJECT(S): Twenty women undergoing laparoscopy for tubal sterilization or hysterectomy for uterine fibroids. INTERVENTION(S): The mucosal layer was isolated from the oviduct tissue, and semiquantitative RT-PCR was performed. MAIN OUTCOME MEASURE(S): The relationship between serum estradiol, luteinizing hormone, and progesterone concentrations and the expression of oviductin mRNA. RESULT(S): There was a significant positive correlation between serum estradiol and luteinizing hormone concentrations and oviductin mRNA expression. There was a significant inverse correlation between serum progesterone concentrations and oviductin mRNA expression. CONCLUSION(S): Little is known about the regulation of human oviductin. This study was the first to examine the relationship between oviductin mRNA expression and serum estradiol and luteinizing hormone and progesterone concentrations in fertile women. Estradiol and luteinizing hormone both have a stimulatory effect on oviductin mRNA in humans, however, it is difficult to determine whether the effects are independent of one another, as the luteinizing hormone surge is dependent on the estradiol increase. Progesterone shows a clear inhibitory effect on oviductin mRNA.

RESUMO

Gonadotrophin-releasing hormone (GnRH) analogues improve the outcome of treatment with IVF by increasing the number and quality of oocytes retrieved and by reducing cycle cancellation rates. Whilst short-acting GnRH analogues are most commonly used, depot preparations are now available that are more convenient for patient use. Some studies have reported that pregnancy rates with depot GnRH analogues are similar to those of short-acting preparations, but others have suggested that the more profound down-regulation seen with depot GnRH analogues results in inferior embryo quality. The purpose of this study was to determine whether a lower than conventional dose of a depot GnRH analogue may be more appropriate for use in ovarian stimulation prior to IVF. Sixty patients were randomized to receive either 3.75 mg (conventional dose) or 1.87 mg (low dose) triptorelin prior to ovarian stimulation for IVF. Suppression was measured using serum concentrations of LH measured 2 and 3 weeks after the administration of the GnRH analogues, the dose of gonadotrophin used and the time to resumption of menses. Mean concentrations of LH were 2.2 +/- 1.0 and 1.1 +/- 0.6 IU/l in the conventional dose group and 3.5 +/- 5.5 and 2.7 +/- 1.9 IU/l in the low dose group (P < 0.05 at 2 and 3 weeks). There were no significant differences between the doses of gonadotrophins used, the number of oocytes and embryos available and the time to resumption of menses, nor in the pregnancy rates. Although the degree of suppression as measured biochemically was more profound with the conventional dose, this did not affect the IVF outcome. The use of a lower dose therefore appears to be equally effective and could contribute to a reduction in the cost of treatment.

RESUMO

Assisted reproductive technologies refer to procedures in which the oocyte is handled or manipulated in vitro before replacement, either as an oocyte or an embryo. Because of rapid advances in this area, infertile couples may seek direct referral for assisted reproductive treatments, instead of trying simpler measures such as ovulation induction and intrauterine insemination. It is important to establish whether these conventional infertility treatments are appropriate, as such treatments are generally safer, less stressful, and more affordable. On the other hand, subjecting infertile couples to unnecessary delay by offering inappropriate treatments-for example, ovulation induction for tubal infertility or intrauterine insemination for severe male-factor infertility-would reduce the overall chance of success because of the age-related decline in female fecundity. The choice of infertility treatments thus depends on a balance of factors: the chance of pregnancy without treatment; the chance with simpler and safer, but less successful, infertility treatments; or the chance with the more complex and costly, but more effective, assisted reproductive treatments. The factors that should be taken into consideration include the age of the woman, the duration of infertility, the causes of infertility, the availability and cost of alternative treatments, and-most importantly-the acceptability.
