Endometrial scratching in women with implantation failure after a first IVF/ICSI cycle; does it lead to a higher live birth rate? The SCRaTCH study: a randomized controlled trial (NTR 5342).

BACKGROUND: Success rates of assisted reproductive techniques (ART) are approximately 30%, with the most important limiting factor being embryo implantation. Mechanical endometrial injury, also called 'scratching', has been proposed to positively affect the chance of implantation after embryo transfer, but the currently available evidence is not yet conclusive. The primary aim of this study is to determine the effect of endometrial scratching prior to a second fresh in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) cycle on live birth rates in women with a failed first IVF/ICSI cycle. METHOD: Multicenter randomized controlled trial in Dutch academic and non-academic hospitals. A total of 900 women will be included of whom half will undergo an endometrial scratch in the luteal phase of the cycle prior to controlled ovarian hyperstimulation using an endometrial biopsy catheter. The primary endpoint is the live birth rate after the 2nd fresh IVF/ICSI cycle. Secondary endpoints are costs, cumulative live birth rate (after the full 2nd IVF/ICSI cycle and over 12 months of follow-up); clinical and ongoing pregnancy rate; multiple pregnancy rate; miscarriage rate and endometrial tissue parameters associated with implantation failure. DISCUSSION: Multiple studies have been performed to investigate the effect of endometrial scratching on live birth rates in women undergoing IVF/ICSI cycles. Due to heterogeneity in both the method and population being scratched, it remains unclear which group of women will benefit from the procedure. The SCRaTCH trial proposed here aims to investigate the effect of endometrial scratching prior to controlled ovarian hyperstimulation in a large group of women undergoing a second IVF/ICSI cycle.

Professionals' perceptions of their patients' experiences with fertility care.

BACKGROUND: Patient-centredness is one of the core dimensions of quality of care. It can be monitored with surveys measuring patients' experiences with care. The objective of the present study was to determine to what extent gynaecologists, physicians specializing in infertility and nurses can estimate the level of patient-centredness of their clinic. METHODS: A random sample of 1189 couples with fertility problems and 194 physicians and nurses from 29 Dutch fertility clinics participated in this cross-sectional study. Differences between patients' experiences with fertility care and professionals' perceptions of these experiences as measured with the patient-centredness questionnaire-infertility (PCQ-infertility) were calculated. The questionnaire's structure, comprising one total scale (level 1), seven subscales (level 2) and 46 single items (level 3), was used as a framework. RESULTS: Response rates were 75% (n = 888) in the patient sample and 83% (n = 160) in the professional sample. Independent sample t-tests, corrected for multiple comparisons with the Bonferroni correction method (P < 0.05), showed no significant differences in mean scores on the total scale of patient-centredness for either professionals or patients. At level 2, professionals underestimated most subscales, namely, 'Accessibility', 'Communication', 'Patient involvement' and 'Competence', whereas 'Continuity of care' was overestimated. Professionals significantly and clinically relevantly misjudged 29 care aspects. CONCLUSIONS: Professionals within fertility care cannot adequately evaluate their performance regarding patient-centredness, and specifically the care aspects to which their own patients attribute the greatest improvement potential. Providing detailed feedback might start improvement of patient-centredness and quality of care.

Why don't we perform elective single embryo transfer? A qualitative study among IVF patients and professionals.

BACKGROUND: Elective single embryo transfer (eSET) enables the prevention of multiple pregnancies after in vitro fertilization (IVF). However, in Europe, the multiple pregnancy rate after IVF remains stable at approximately 23%, with SET occurring in 15% of all IVF cycles. In most European clinics, the decision for the number of embryos transferred is established through a form of shared decision-making between patients and professionals. The aim of this study is to explore factors influencing this decision, in particular factors preventing eSET use. METHODS: We performed explorative, semi-structured, in-depth interviews, based on two theoretical models. The interviews were performed among 19 Dutch IVF professionals and 20 patients who had just undergone IVF or were on the waiting list for IVF. The interviews were fully transcribed and two researchers independently scored the factors according to the models. RESULTS: We identified a wide variety of factors, potentially influencing eSET use: 37 with the professionals and 26 among the patients. Examples of factors mentioned by both patients and professionals were: uncertainty about the eSET technique, couples' lack of knowledge about essential eSET aspects, absence of a reimbursement system which favours eSET, inadequate options to select couples suitable for eSET and inferior cryopreservation success rates. CONCLUSIONS: This study demonstrates that both IVF professionals and patients identify numerous factors preventing eSET use in clinical practice. To estimate the impact of these factors identified, a quantitative confirmation and assessment of the magnitude of the effect is necessary.

[Polycythaemia in a patient with uterus myomatosus]. / Polycytemie bij een patiënte met een uterusmyoom.

BACKGROUND: Myomatous erythrocytosis syndrome (MES) is characterised by a combination of polycythaemia, uterus myomatosus and the normalisation of erythrocyte count after hysterectomy. CASE DESCRIPTION: A 58-year-old postmenopausal woman was referred to the gynaecologist with symptoms of vaginal blood loss, increased abdominal circumference and pollakiuria. Physical examination indicated her uterus was enlarged to the size of a 24-week gestation. Endometrial malignancy was excluded and ultrasound showed a myoma. In consultation with the patient a hysterectomy was planned. Pre-operative blood tests showed increased haemoglobin levels (14.2 mmol/l). No indications of polycythaemia vera or secondary polycythaemia were found after which the diagnosis of MES was made. Haemoglobin levels normalised after hysterectomy without any further intervention. CONCLUSION: MES is common, although relatively unknown. Its pathophysiology is most likely based on ectopic production of erythropoietin by leiomyoma tissue. The combination of polycythaemia and uterus myomatosus should alert clinicians to this syndrome, especially as polycythaemia normalises after hysterectomy.

Inspection of the ovaries and steroids in serum and peritoneal fluid at various time intervals after ovulation in fertile women: implications for the luteinized unruptured follicle syndrome.

In 20 fertile women one menstrual cycle was monitored by ovarian ultrasonography, laparoscopy, and estimation of 17 beta-estradiol (E2) and progesterone levels in serum and peritoneal fluid (PF). Three groups were studied, performing the laparoscopy within 1, 3, and 5 days after ovulation. The results indicate that the opening in the corpus luteum remains at least during the first 1.5 postovulatory days. The process of the closure starts thereafter and has been accomplished 4 to 5 days after ovulation. Progesterone and E2 levels in PF follow a similar pattern, showing high levels in the first, decreasing levels in the second, and low levels in the last laparoscopy groups. Therefore the significance of inspection of the ovaries and hormone level estimation in PF depend on the timing of the laparoscopy in relation to the moment of ovulation, especially in the first 5 postovulatory days.

Heterogeneity in the origin of recurrent complete hydatidiform moles: not all women with multiple molar pregnancies have biparental moles.

Hydatidiform moles of two women, each with three molar pregnancies, were examined in order to study their origin. Multiple recurrences have previously been associated with women who have biparental complete hydatidiform moles (CHM). However, all the moles examined in this study were androgenetic CHM (AnCHM), indicating that recurrent (>2) moles, particularly in the absence of a positive family history, may be androgenetic rather than biparental. These data suggest that some women have a specific liability for having AnCHM. Making the distinction between a biparental or an androgenetic origin of recurrent moles is of relevance for counselling and when considering therapeutic options. Therefore, we propose that all recurrent moles should be investigated using molecular techniques.

The origin of estrogens, progesterone, androgens and sex hormone binding globulin in peritoneal fluid in the immediate postovulatory period in normal ovulating women.

In 20 women with proven fertility, one menstrual cycle was monitored by ovarian ultrasonography, laparoscopy and estimation of 17 beta-estradiol (E2), estrone (E1), progesterone, testosterone, androstenedione (Adion), dehydroepiandrosterone (DHEA), dehydroepiandrosterone sulfate (DHEAS), and sex hormone binding globulin (SHBG) in serum and peritoneal fluid. Three groups were studied, in which the peritoneal fluid was collected within 1, 3 and 5 days after ovulation. E1, E2 and progesterone levels in peritoneal fluid were highest shortly after ovulation and decreased with time. Testosterone and Adion in peritoneal fluid showed no changes, but peritoneal fluid levels were always higher than serum levels. No differences were found between the peritoneal fluid and serum levels of DHEA and DHEAS. SHBG in serum was always higher than in peritoneal fluid. The results are compared with reported steroid levels in follicular fluid from the literature and factors complicating the interpretation of steroid levels in peritoneal fluid are discussed.

Antibody and complement-binding activity of viable and nonviable human spermatozoa.

Antibody and complement fixation by viable and nonviable spermatozoa were studied by means of immunofluorescence and a hemolytic assay (CH-50). Spermatozoa were incubated in sera from fertile male and female donors and in peritoneal fluid from fertile women undergoing laparoscopy. Nonviable spermatozoa were able to bind antibody or complement from sera and peritoneal fluid. There was no evidence of antibody or complement fixation by viable spermatozoa. The antibodies present in the serum that bind to spermatozoa belong to the IgG and IgM class; in peritoneal fluid, only IgG could be found. Complement fixation occurred via the classical (antibody-mediated) and alternative pathway. Viable spermatozoa possess antigenic properties different from nonviable spermatozoa. The lack of immunological reaction of women to viable spermatozoa and a possible mechanism for immunological infertility is considered.
