Observer agreement in the evaluation of the uterine cavity by hysteroscopy prior to in vitro fertilization (Article)

2011-04-01T00:00:00Z

Background Hysteroscopy is known as the most accurate test for diagnosing intrauterine pathology. To optimize fertility treatment, it is increasingly common to perform hysteroscopy as a routine procedure prior to IVF. However, literature on the reproducibility of screening hysteroscopy is lacking. Therefore, the aim of the study was to assess the intra- and inter-observer agreement in the individual evaluation of the uterine cavity using video recordings of hysteroscopy procedures in asymptomatic patients prior to IVF.Methods Screening hysteroscopies of 123 unselected, asymptomatic, infertile women with an indication for IVF/ICSI treatment were recorded on DVD. After editing, the hysteroscopy performer and three other experienced gynecologists independently assessed all recordings, focusing on the appearance of predefined intrauterine abnormalities (i.e. endometrial polyps, myomas, adhesions or septa). The intra- and inter-observer agreement was calculated and expressed as perfect agreement and κ coefficient or intraclass correlation coefficient.Results In total, 123 hysteroscopy procedures were recorded. After editing and selection, based on the record quality, 107 remained for assessment and analysis. The intraobserver agreement on the appearance of any of the predefined intrauterine abnormalities was substantial (κ 0.707), whereas the interobserver agreement was moderate (κ 0.491). Perfect agreement occurred only in 77.6 of the cases. Conclusions Interobserver agreement among experienced gynecologists appeared to be rather disappointing. The latter may have implications for the diagnostic accuracy of screening hysteroscopy prior to IVF, as well as for its clinical significance in IVF programs.

Use rate and assisted reproduction technologies outcome of cryopreserved semen from 629 cancer patients (Article)

2008-12-01T00:00:00Z

Objective: To assess the use rate and assisted reproductive technologies (ART) outcome of the cryopreserved semen of cancer patients with an average follow-up of 7 years (range, 2-23 years). Design: Retrospective data analysis. Setting: University-affiliated andrology and reproduction center. Patient(s): Six hundred twenty-nine male cancer patients who were referred for semen cryopreservation between 1983 and 2004. Intervention(s): Review of patient characteristics and ART outcome. Main Outcome Measure(s): Use rate and live births using cryopreserved semen. Result(s): A total of 749 semen samples from 557 men were preserved. Ninety-one patients died during follow-up, and another 29 requested disposal. Forty-two patients requested the use of their banked semen. ART data were available for 37 patients. A total of 101 ART cycles (32 IVF, 53 intracytoplasmic sperm injection [ICSIs], nine cryo-ET, and seven intrauterine inseminations [IUIs]) were performed, resulting in, respectively, 8, 16, 2, and 1 pregnancies. Pregnancies rates for IVF and ICSI were significantly higher than those for IUI. Conclusion(s): So far, 7.5% of the cancer survivors have used their banked semen, which led to live births in 49% of the couples. Semen cryopreservation is a reliable method to preserve fertility potential and gives couples a reasonable chance of achieving parenthood.

Lipid profile of women with premature ovarian failure (Article)

2008-09-01T00:00:00Z

OBJECTIVE: Earlier menopause is associated with a higher incidence of cardiovascular events later in life. Concurrent with the ages of menopausal transition, a shift in lipid profile takes place. Premature ovarian failure (POF) or premature menopause allows us to study the effect of cessation of ovarian function on the lipid profile independent of effects of advanced chronological age. DESIGN: Fasting triglycerides (TGs), total high-density lipoprotein (HDL), and low-density lipoprotein cholesterol levels were measured in 90 women with POF not using any hormone therapy and 198 population controls of the same age range not using oral contraceptives. Correlations between lipids and ovarian function parameters were assessed. RESULTS: After correction for age, body mass index, and smoking, women with POF presented with significantly higher TG levels (mean difference: 0.17 log mmol/L [95% CI: 0.06-0.29]). HDL cholesterol levels were borderline significantly lower in women with POF. No age-corrected correlation between triglycerides or other lipids and estradiol levels or time of estrogen deprivation could be identified. However, the free androgen index, sex hormone-binding globulin, and testosterone concentrations showed significant correlations with TGs and/or HDL cholesterol concentrations. CONCLUSIONS: Loss of ovarian function at a very young age (POF) coincides with subtle changes in the lipid profile (higher TG levels and marginally lower HDL). Androgens (increased free androgen index and testosterone and decreased sex hormone-binding globulin) are better markers for unfavorable lipid changes compared with estrogen levels or duration of estrogen deprivation in women with POF. Elevated TG levels in combination with increased (free) androgens may be an early manifestation of reduced insulin sensitivity.

The METEX study: Methotrexate versus expectant management in women with ectopic pregnancy: A randomised controlled trial (Article)

2008-06-19T00:00:00Z

Background: Patients with ectopic pregnancy (EP) and low serum hCG concentrations and women with a pregnancy of unknown location (PUL) and plateauing serum hCG levels are commonly treated with systemic methotrexate (MTX). However, there is no evidence that treatment in these particular subgroups of women is necessary as many of these early EPs may resolve spontaneously. The aim of this study is whether expectant management in women with EP or PUL and with low but plateauing serum hCG concentrations is an alternative to MTX treatment in terms of treatment success, future pregnancy, health related quality of life and costs. Methods/Design: A multicentre randomised controlled trial in TheNetherlands. Hemodynamically stable patients with an EP visible on transvaginal ultrasound and a plateauing serum hCG concentration < 1,500 IU/L or with a persisting PUL with plateauing serum hCG concentrations < 2,000 IU/L are eligible for the trial. Patients with a viable EP, signs of tubal rupture/abdominal bleeding, or a contra-indication for MTX will not be included. Expectant management is compared with systemic MTX in a single dose intramuscular regimen (1 mg/ kg) in an outpatient setting. Serum hCG levels are monitored weekly; in case of inadequately declining, systemic MTX is installed or continued. In case of hemodynamic instability and/or signs of tubal rupture, surgery is performed. The primary outcome measure is an uneventful decline of serum hCG to an undetectable level by the initial intervention. Secondary outcomes are (re)interventions (additional systemic MTX injections and/or surgery), treatment complications, health related quality of life, financial costs, and future fertility. Analysis is performed according to the intention to treat principle. Quality of life is assessed by questionnaires before and at three time points after randomisation. Costs are expressed as direct costs with data on costs and used resources in the participating centres. Fertility is assessed by questionnaires after 6, 12, 18 and 24 months. Patients' preferences will be assessed using a discrete choice experiment. Discussion: This trial will provide guidance on the present management dilemmas in women with EPs and PULs with low and plateauing serum hCG concentrations.

Decreased androgen concentrations and diminished general and sexual well-being in women with premature ovarian failure (Article)

2008-01-01T00:00:00Z

OBJECTIVE: To describe general and sexual well-being in women with premature ovarian failure (POF) and to investigate whether there is a relationship between androgen levels and sexual functioning. DESIGN: Women with POF and healthy volunteers with regular menstrual cycles participated. Participants completed a written questionnaire and underwent hormonal screening. The questionnaire included standardized measures: the Questionnaire for Screening Sexual Dysfunctions, the Shortened Fatigue Questionnaire, and the Symptom Check List-90. Serum hormone measurements included estradiol, total testosterone, bioavailable testosterone, androstenedione, dehydroepiandrosterone, and dehydroepiandrosterone sulfate. RESULTS: Eighty-one women with POF and 68 control women participated in the study. Compared with control women, women with POF reported more complaints of anxiety, depression, somatization, sensitivity, hostility, and psychological distress. Overall women with POF were less satisfied with their sexual life. They had fewer sexual fantasies and masturbated less frequently. Sexual contact was associated with less sexual arousal, reduced lubrication, and increased genital pain. However, the frequency of desire to have sexual contact and the frequency of actual sexual contact with the partner did not differ between women with POF and control women. Women with POF had lower levels of estradiol, total testosterone, and androstenedione. Multiple regression analysis revealed that androgen levels had only a weak influence on sexual functioning; higher total testosterone levels were associated with increased frequency of desire for sexual contact, and higher androstenedione levels were associated with elevated frequency of sexual contact. CONCLUSIONS: Women with POF have diminished general and sexual well-being and are less satisfied with their sexual lives than control women. Although women with POF had lower androgen levels, we did not find an important independent role for androgens in various aspects of sexual functioning.

Does metformin modify ovarian responsiveness during exogenous FSH ovulation induction in normogonadotrophic anovulation? A placebo- controlled double-blind assessment. (Article)

2005-04-01T00:00:00Z

OBJECTIVE: To assess whether the addition of metformin to gonadotrophin ovulation induction in insulin-resistant, normogonadotrophic, anovulatory women alters ovarian responsiveness to exogenous FSH. DESIGN: Placebo-controlled double-blind assessment in an academic hospital. RESULTS: After a progestagen withdrawal bleeding, patients were randomised for either metformin (n = 11) or placebo (n = 9) treatment. In cases of absent ovulation, exogenous FSH was subsequently administered to induce ovulation. Only during metformin treatment did body mass index and androgen (androstenedione and testosterone) levels decrease, whereas FSH and LH levels increased significantly. In the metformin group, a single patient ovulated before the initiation of exogenous FSH. Significantly more monofollicular cycles and lower preovulatory oestradiol concentrations were observed in women receiving FSH with metformin compared with FSH alone. CONCLUSIONS: Metformin co-treatment in a group of insulin-resistant, normogonadotrophic, anovulatory patients resulted in normalization of the endocrine profile and facilitated monofollicular development during the FSH induction of ovulation.

Is there a future for ovulation induction in the current era of assisted reproduction? (Article)

2003-01-01T00:00:00Z

The clinical use of medical induction of ovulation in normogonadotrophic anovulatory women (WHO II), including polycystic ovary syndrome, is increasingly questioned. However, we believe that this treatment modality still represents a highly effective means of fertility treatment in women with low pregnancy chances without intervention. A conventional treatment algorithm involving clomiphene citrate (CC) followed by FSH induction of ovulation may result in a 71% cumulative singleton live birth rate. In attempts to improve treatment outcome further and reduce complication rates, new compounds such as insulin-sensitizing agents or aromatase inhibitors are currently used increasingly. Approaches such as patient selection for different treatment modalities on the basis of initial screening characteristics and alternative protocols for FSH ovulation induction may also be proposed to render treatment algorithms more patient tailored and therefore improve overall outcomes. More research is needed in this area, rather than referring these patients to assisted reproduction prematurely. This may lead to a more individually tailored approach for ovulation induction in a given patient, resulting in a further improvement of the balance between chances for success versus complications.

Urinary follicle-stimulating hormone for normogonadotropic clomiphene-resistant anovulatory infertility: prospective, randomized comparison between low dose step-up and step-down dose regimens (Article)

1997-01-01T00:00:00Z

A low dose step-up and step-down regimen for induction of ovulation using urinary FSH was compared in a prospective randomized fashion in 37 normogonadotropic clomiphene-resistant oligo- or amenorrheic infertile women. The objectives was to assess potential differences in duration of treatment, ovarian stimulation (serum FSH levels), and response [serum estradiol (E2) levels and number and size of follicles]. Monitoring (blood sampling and transvaginal sonography) took place on the day of initiation of treatment, the first day of ovarian response as assessed by ultrasound (i.e. the first day a follicle > or = 10 mm could be recognized), the day of hCG administration to induce ovulation, and 3 days thereafter. The median duration of treatment in the low dose step-up group was 18 (range, 7-41) days compared to 9 (range, 4-16) days in the step-down group (P = 0.003), and the total numbers of ampules administered were 20 (range, 7-69) and 14 (range, 7-33), respectively (P = NS). Serum FSH levels from the first day of sonographic ovarian response until the administration of hCG were constant (median increase, 2%/day) in patients receiving the low dose step-up protocol, but showed a decrease (median, 5%/day) in step-down cycles (P < 0.001). Monofollicular growth, defined as not more than one follicle 16 mm or larger on the day of hCG administration, was observed in 56% of low dose step-up and 88% of step-down cycles (P = 0.04). The percentage of patients with normal range periovulatory E2 serum levels (500-1500 pmol/L) was 33% in the low dose step-up group vs. 71% in the step-down group (P = 0.03). We conclude that a step-down protocol for gonadotropin induction of ovulation exhibits a more physiological, late follicular phase FSH serum profile than a low dose step-up protocol. This results in a shorter duration of treatment, a greater number of monofollicular cycles, and more cycles with periovulatory E2 levels within the normal range in the step-down protocol.
