[The Thromboembolism Risk with Combined Hormonal Contraceptives: Current Status and Prescribing Practice]. / Thromboembolierisiko unter kombinierten hormonellen Kontrazeptiva ­ aktueller Stand und Verschreibungspraxis.

The Thromboembolism Risk with Combined Hormonal Contraceptives: Current Status and Prescribing Practice Abstract. The use of combined hormonal contraceptives (CHC) increases not only the risk for venous thromboembolism, but also for arterial thromboembolism. The risk for thromboembolism is the same for non-oral CHC (patches, vaginal rings) as for oral CHC. Risk factors such as age >35, obesity, smoking and a positive family history need to be recognized and considered in contraceptive counselling. Elaborate information concerning risks and benefits is mandatory. This applies to first-time as well as long-term users. Careful investigation of the history is required, and the risk factors need to be re-evaluated at yearly prescription. It is also very important to inform the patients about the early symptoms of thrombosis or pulmonary embolism, so that therapy can be started immediately. Apart from these risks, CHC may have beneficial effects on organs such as the ovaries, the endometrium and the general well-being for many women. When prescribing a CHC for the first time or when changing to another preparation, one should always weigh up whether certain benefits justify prescribing a preparation with a slightly higher risk of thrombosis compared to the second-generation pill or preparations with Estradiol/Nomegestrolacetat. Women who are already using a third-generation pill or a pill with drospirenone or cyproterone acetate and feel comfortable with it do not need to switch to another preparation (provided no new risk factors have arisen). For women with increased risks, i.e. several relative contraindications or one absolute contraindication, safe alternatives to CHC include progestogen-only preparations, intrauterine devices containing copper or levonorgestrel or, after family planning has been completed, surgical methods (sterilisation/vasectomy).

Cognitive function in association with high estradiol levels resulting from fertility treatment.

The putative association between hormones and cognitive performance is controversial. While there is evidence that estradiol plays a neuroprotective role, hormone treatment has not been shown to improve cognitive performance. Current research is flawed by the evaluation of combined hormonal effects throughout the menstrual cycle or in the menopausal transition. The stimulation phase of a fertility treatment offers a unique model to study the effect of estradiol on cognitive function. This quasi-experimental observational study is based on data from 44 women receiving IVF in Zurich, Switzerland. We assessed visuospatial working memory, attention, cognitive bias, and hormone levels at the beginning and at the end of the stimulation phase of ovarian superstimulation as part of a fertility treatment. In addition to inter-individual differences, we examined intra-individual change over time (within-subject effects). The substantial increases in estradiol levels resulting from fertility treatment did not relate to any considerable change in cognitive functioning. As the tests applied represent a broad variety of cognitive functions on different levels of complexity and with various brain regions involved, we can conclude that estradiol does not show a significant short-term effect on cognitive function.

Diagnosis and Therapy Before Assisted Reproductive Treatments. Guideline of the DGGG, OEGGG and SGGG (S2k Level, AWMF Register Number 015-085, February 2019) - Part 1, Basic Assessment of the Woman.

Introduction Supporting and counselling couples with fertility issues prior to starting ART is a multidisciplinary diagnostic and therapeutic challenge. The first German/Austrian/Swiss interdisciplinary S2k guideline on "Diagnosis and Therapy Before Assisted Reproductive Treatments (ART)" was published in February 2019. This guideline was developed in the context of the guidelines program of the German Society of Gynecology and Obstetrics (DGGG) in cooperation with the Swiss Society of Gynecology and Obstetrics (SGGG) and the Austrian Society of Gynecology and Obstetrics (OEGGG). Aims One third of the causes of involuntary childlessness are still unclear, even if the woman or man have numerous possible risk factors. Because the topic is still very much taboo, couples may be socially isolated and often only present quite late to a fertility center. At present, there is no standard treatment concept, as currently no standard multidisciplinary procedures exist for the diagnostic workup and treatment of infertility. The aim of this guideline is to provide physicians with evidence-based recommendations for counselling, diagnostic workup and treatment. Methods This S2k guideline was developed on behalf of the Guidelines Commission of the DGGG by representative members from different professional medical organizations and societies using a structured consensus process. Recommendations The first part of this guideline focuses on the basic assessment of affected women, including standard anatomical and endocrinological diagnostic procedures and examinations into any potential infections. Other areas addressed in this guideline are the immunological workup with an evaluation of the patient's vaccination status, an evaluation of psychological factors, and the collection of data relating to other relevant factors affecting infertility. The second part will focus on explanations of diagnostic procedures compiled in collaboration with specialists from other medical specialties such as andrologists, human geneticists and oncologists.

Introduction Supporting and counselling couples with fertility issues prior to starting ART is a multidisciplinary diagnostic and therapeutic challenge. The first German-language interdisciplinary S2k guideline on "Diagnosis and Therapy Before Assisted Reproductive Treatments (ART)" was published in February 2019. The guideline was developed in the context of the guidelines program of the German Society of Gynecology and Obstetrics (DGGG) in cooperation with the Swiss Society of Gynecology and Obstetrics (SGGG) and the Austrian Society of Gynecology and Obstetrics (OEGGG). Aim In one third of cases, the cause of involuntary childlessness remains unclear, even if the woman or man have numerous possible risk factors. Because the topic is still very much taboo, couples may be socially isolated and often only present quite late to a fertility center. There is no standard treatment concept for these patients at present, as there are currently no standard multidisciplinary procedures for the diagnostic workup and treatment of infertility.

Methods This S2k guideline was developed on behalf of the Guidelines Commission of the DGGG by representative members from different professional medical organizations and societies using a structured consensus process. Recommendations This second part of the guideline describes the hematological workup for women as well as additional diagnostic procedures which can be used to investigate couples and which are carried out in cooperation with physicians working in other medical fields such as andrologists, geneticists and oncologists.

Ten-year single-centre experience in fertility preservation of 459 patients suffering from acute leukaemia.

Acute leukaemia is a life-threatening disease that needs treatment without delay. Fertility preservation is recommended, but often not possible because of the necessity to start treatment as soon as possible. The present study is a retrospective single-centre analysis of 459 patients diagnosed with acute leukaemia between 2002 and 2012. Sperm or oocyte preservation was successfully performed in only 29 (6%) patients. Of the 150 children, no paediatric patient sample was taken. The collected samples enabled the conception of 2 children by in vitro fertilisation; in addition, 3 spontaneous, non-assisted births in partners of male patients were observed. Fertility preservation is important but difficult to accomplish in patients with acute leukaemia; more efforts are clearly needed to preserve fertility in long-term survivors of acute leukaemia.

Antibodies to Chlamydia trachomatis and reproductive health issues in women with SLE: a case-control study.

BACKGROUND: SLE is an autoimmune condition affecting predominantly women. Little is known regarding Chlamydia trachomatis infection in women with SLE, which may drive autoimmunity and contribute to obstetrical and vascular complications. METHODS: This single-centre, case-control study set primary endpoint in the comparative seropositivity rate to C. trachomatis major outer membrane protein (MOMP) and chlamydial heat-shock protein-60 (cHSP60) in age-matched subjects. The secondary endpoints were obstetrical outcomes, cardiovascular events and results from screening procedures for cervical cancer. RESULTS: Eighty-four women with SLE and 50 age-matched controls were included. Seropositivity to C. trachomatis did not differ significantly between groups (10% of cases positive for anti-MOMP vs 12% of controls; 43% of cases positive for anti-cHSP60 vs 32% of controls). Women with SLE were more often of non-Caucasian ethnicity and had lower educational level. They relied less frequently on oral contraception and resorted more frequently to elective pregnancy termination. Pre-eclampsia and ectopic pregnancy occurred only in SLE. Women with SLE also experienced more cardiovascular events. In SLE, antibodies to cHSP60 were associated with a history of pericarditis and abnormal screening tests for cervical cancer. Antibody titres to C. trachomatis were not associated with disease activity or SLE treatment, nor were there associations with other gynaecological, obstetrical or vascular outcomes. CONCLUSION: Prevalence of antibodies to C. trachomatis was not increased in women with SLE. No significant association was found between these antibodies and obstetrical or cardiovascular complications.

Anxiety, depression, and attachment before and after the first-trimester screening for Down syndrome: comparing couples who undergo ART with those who conceive spontaneously.

OBJECTIVES: This study's aim was to describe the emotional status of parents to be before and after the first-trimester combined prenatal screening test. METHODS: One hundred three couples participated, of which 52 had undergone an in vitro fertilization/intracytoplasmic sperm injection treatment [assisted reproductive technology (ART)] and 51 had conceived spontaneously. Participants completed the state scale of the State-trait Anxiety Inventory, the Edinburgh Depression Scale, and the Maternal and Paternal Antenatal Attachment Questionnaire before the first-trimester combined prenatal screening test at around 12 weeks of gestational age (T1) and just after receiving the results at approximately 14 weeks of gestational age (T2). RESULTS: We observed a significant decrease in anxiety and depression symptoms and a significant increase in attachment from T1 to T2. Results showed no differences between groups at either time point, which suggests that ART parents are more similar to than different from parents conceiving spontaneously. Furthermore, given the importance of anxiety during pregnancy, a subsample of women with clinical anxiety was identified. They had significantly higher rates of clinical depression and lower attachment. CONCLUSIONS: These results indicate that, regardless of whether conception was through ART or spontaneous, clinical anxiety in women over the prenatal testing period is associated with more vulnerability during pregnancy (i.e. clinical depression and less attachment to fetus).

Effect of embryo culture media on birthweight and length in singleton term infants after IVF-ICSI.

QUESTIONS UNDER STUDY: To investigate if two distinct, commercially available embryo culture media have a different effect on birthweight and length of singleton term infants conceived after IVF-ICSI. METHODS: University hospital based cohort study. Between 1 January 2000 and 31 December 2004, patients conceiving through IVF-ICSI at the University Hospital, Lausanne have been allocated to two distinct embryo culture media. Only term singleton pregnancies were analysed (n = 525). Data analysis was performed according to two commercially available culture media: Vitrolife (n = 352) versus Cook (n = 173). Analysis was performed through linear regression adjusted for confounders. Media were considered equivalent if the 95% confidence interval lay between -150 g/+150 g. RESULTS: Length, gestational age and distribution of birthweight percentiles did not differ between groups (for both genders). Analysis of the whole cohort, adjusted for a subset of confounders, resulted in a statistically not different mean birthweight between the two groups (Vitrolife +37 g vs Cook, 95%CI: -46 g to 119 g) suggesting equivalence. Adjustment for an enlarged number of confounders in a subsample of patients (n = 258) also revealed no relevant mean birthweight difference of +71 g (95%CI: -45 g to 187 g) in favour of Vitrolife; however, lacking power to prove equivalence. CONCLUSIONS: Our data suggest that significant differences in birthweight due to these two distinct, commercially available embryo culture media are unlikely.

Anxiety and psychological stress before prenatal screening in first-time mothers who conceived through IVF/ICSI or spontaneously.

Mothers' general anxiety, anxiety about the well-being of the child and psychological stress before prenatal testing was studied by comparing women who conceived through in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) with women who conceived naturally. Before the first trimester screening test for Down's syndrome, a group of 51 women who conceived through IVF/ICSI and a group of 54 women who conceived spontaneously completed the State Scale of the State-Trait Anxiety Inventory (S-Anxiety; Spielberger, 1983), the Fear of Bearing a Physically or Mentally Handicapped Child Subscale of the Pregnancy-related Anxiety Questionnaire (PRAQ-R; Huizink et al., 2004), the Psychological Stress Measure (PSM; Lemyre & Tessier, 1988), and the Prenatal Psychosocial Profile (PPP; Curry, Campbell, & Christian, 1994). Women who conceived through IVF/ICSI had more elevated levels of general anxiety and psychological stress than the women who conceived naturally; however, no difference was observed between the two groups for anxiety specifically related to the health of the child. These results underline the need to monitor women's emotional state after conception via IVF/ICSI-when counseling usually ends-and around the time of the first trimester screening. Counseling might thus be extended.

[The global consensus statement 2013 on menopausal hormone therapy]. / A propos du consensus international 2013 sur le traitement hormonal de la ménopause.

More than ten years after the publication of the "Women's Health Initiatives" (WHI) study, a global consensus statement on menopausal hormone replacement therapy (HRT) has been edited by an expert committee, composed by all the international menopausal societies. This global consensus has been published in April 2013 in the journal Climacteric. In conclusion, HRT has to be an individual decision, weighing up benefits and risks and it should not be prescribed for the first time in women older than 60 years or more than ten years after the onset of menopause. Dose and duration of HRT are individual and the indication has to be reevaluated annually. HRT is contraindicated in breast cancer survivors.

Origin and outcome of multiple pregnancies in Bern, Switzerland, 1995-2006 and the current proposal of the Swiss parliament to revise the Swiss law of reproductive medicine: Switzerland quo vadis?

INTRODUCTION: Infertility treatments are a major source of the increase in multiple pregnancies (MPs). AIMS: The aims of the present study were (1.) to investigate the origin and maternal/neonatal outcomes of MP and (2.) to review the different measures that can be adopted to reduce these serious complications. METHODS: The study included all women with multiple births between 1 January 1995 and 31 December 2006 at the University Hospital of Bern, Switzerland. The outcomes associated with the various origins of MP (natural conception, ovarian stimulation [OS]--in-vitro fertilisation [IVF-ICSI]) were analysed using a multinomial logistic regression model. An analysis of the Swiss law on reproductive medicine and its current proposed revision, as well as a literature review using Pubmed, was carried out. RESULTS: A total of 592 MP were registered, 91% (n = 537) resulted in live births. There was significantly more neonatal/maternal morbidity in MP after OS compared with natural conception and even with the IVF-ICSI group. With a policy of elective single embryo transfer (eSET), twin rates after IVF-ICSI can be reduced to <5% and triplets to <1%. CONCLUSIONS: After OS, more triplets are found and the outcome of MP is worse. MP is known to be associated with morbidity, mortality, and economic and social risks. To counteract these complications (1.) better training for physicians performing OS should be encouraged and (2.) the Swiss law on reproductive medicine needs to be changed, with the introduction of eSET policies. This would lead to a dramatic decrease in neonatal and maternal morbidity/mortality as well as significant cost reductions for the Swiss healthcare system.

Social freezing in Switzerland and worldwide--a blessing for women today?

This is a critical review of the medical, ethical, judicial and financial aspects of the so called "social freezing", the cryopreservation of a woman's oocytes for non-medical purposes. The possibility of storing the eggs of fertile women in order to prevent age-related fertility decline is being widely promoted by fertility centres and the lay press throughout the world. Research data has shown that social freezing should ideally be performed on women around 25 years of age in order to increase their chances of a future pregnancy. In reality, it is mostly performed after the age of 35. Unfortunately, social freezing is in general not a solution for the underlying societal problems to fit in with professionally active women and having children. It only delays the existing problems. Furthermore, it creates a lot of potential new problems. A great deal more should be undertaken to offer real solutions to the underlying societal problems which are in part: pre-school education, care in the event of childhood illness, and the many weeks of school holidays, acceptance of professionally active women having children, and more job offers with a workload <100%.). Furthermore, society should be informed about the decreasing chances of pregnancy with increasing maternal (and paternal) age as well as the increasing risks of miscarriage and obstetric/neonatal complications. Detailed information for woman considering social freezing is crucial. Every doctor, proposing social freezing to his patients, should be up to date with all these details. Follow-up studies on the outcome of these children are needed.

Augmented epithelial multidrug resistance-associated protein 4 expression in peritoneal endometriosis: regulation by lipoxin A(4).

OBJECTIVE: To compare the expression of the prostaglandin (PG) E(2) transporter multidrug resistance-associated protein 4 (MRP4) in eutopic and ectopic endometrial tissue from endometriosis patients with that of control subjects and to examine whether MRP4 is regulated by the antiinflammatory lipid lipoxin A(4) (LXA(4)) in endometriotic epithelial cells. DESIGN: Molecular analysis in human samples and a cell line. SETTING: Two university hospitals and a private clinic. PATIENT(S): A total of 59 endometriosis patients and 32 age- and body mass index-matched control subjects undergoing laparoscopy or hysterectomy. INTERVENTION(S): Normal, eutopic, and ectopic endometrial biopsies as well as peritoneal fluid were obtained during surgery performed during the proliferative phase of the menstrual cycle. 12Z endometriotic epithelial cells were used for in vitro mechanistic studies. MAIN OUTCOME MEASURE(S): Tissue MRP4 mRNA levels were quantified by quantitative reverse-transcription polymerase chain reaction (qRT-PCR), and localization was analyzed with the use of immunohistochemistry. Cellular MRP4 mRNA and protein were quantified by qRT-PCR and Western blot, respectively. PGE(2) was measured in peritoneal fluid and cell supernatants using an enzyme immunoassay (EIA). RESULT(S): MRP4 was expressed in eutopic and ectopic endometrium, where it was overexpressed in peritoneal lesions and localized in the cytoplasm of glandular epithelial cells. LXA(4) attenuated MRP4 mRNA and protein levels in endometriotic epithelial cells in a dose-dependent manner, while not affecting the expression of enzymes involved in PGE(2) metabolism. Investigations employing receptor antagonists and small interfering RNA revealed that this occurred through estrogen receptor α. Accordingly, LXA(4) treatment inhibited extracellular PGE(2) release. CONCLUSION(S): We report for the first time that MRP4 is expressed in human endometrium, elevated in peritoneal endometriosis, and modulated by LXA(4) in endometriotic epithelial cells.

Fertility preservation in cancer patients. Review of the French speaking part of Switzerland and recommendations for different situations.

Due to constant progress in oncology, survival rates of patients (children and adults) with cancer are increasing. Consequently, the reproductive future of young cancer patients needs to be addressed carefully. Fertility preservation techniques are available and issues such as the time available for fertility treatments, patients' age, presence of a partner and patients' personal wishes have to be considered. In Switzerland, a first therapeutic network (Réseau Romand de Cancer et Fertilité), was created in the French speaking part of Switzerland in 2006. Since 2010, a global Swiss network (FertiSave) has been created. The goal of these networks is to maximise the safety and efficacy of fertility preservation options offered to cancer patients without compromising their oncological prognosis. Patients' needs have to be identified, the therapeutic options evaluated rapidly and the optimal treatment promptly implemented in these urgent situations. This article reviews the fertility preservation options currently available and makes recommendations for different specific cancer situations, consistent with the latest scientific evidence and in general agreement with international recommendations.

The expression of estrogen receptors as well as GREB1, c-MYC, and cyclin D1, estrogen-regulated genes implicated in proliferation, is increased in peritoneal endometriosis.

OBJECTIVE: To analyze the expression of estrogen receptors α and ß as well as their target genes implicated in proliferation, c-myc, cyclin D1, and GREB1, in the endometrium of women with or without endometriosis. DESIGN: Expression analysis in human tissue. SETTING: University hospitals and a clinic. PATIENT(S): Ninety-one premenopausal women (59 patients with endometriosis and 32 controls) undergoing laparoscopic surgery. INTERVENTION(S): Biopsies were obtained at time of surgery, performed during the proliferative phase of the cycle. MAIN OUTCOME MEASURE(S): Estrogen receptors α and ß as well as c-myc, cyclin D1, and GREB1 mRNA expression levels were determined by quantitative reverse transcriptase-polymerase chain reaction. Tissue localization of these estrogen-regulated genes was analyzed by immunohistochemistry. RESULT(S): Estrogen receptors α and ß as well as c-myc, cyclin D1, and GREB1 mRNA expression levels were increased in ectopic tissue in comparison with both normal and eutopic endometrium. Estrogen receptor mRNA levels also were upregulated in the eutopic peritoneal tissue of patients with endometriosis. Cyclin D1 and GREB1 expression was augmented in eutopic endometrium. c-myc, cyclin D1, and GREB1 proteins exhibited a nuclear localization in ectopic endometrial tissue. CONCLUSION(S): This constitutes the first report of increased expression of GREB1, as well as cyclin D1 and c-myc, in peritoneal endometriotic lesions, implicating these proteins in estrogen-dependent growth in this context.

Increased endometrial placenta growth factor (PLGF) gene expression in women with successful implantation.

OBJECTIVE: To analyze the vascularization of the endometrium via hysteroscopy and to assess its correlation with angiogenic factor gene expression and embryo implantation rate. DESIGN: Cross-sectional study. SETTING: Public university hospital. PATIENT(S): Patients undergoing hysteroscopy for supposed infertility. INTERVENTION(S): Endometrial quality assessment according to Sakumoto-Masamoto, performed in the early secretory phase of the cycle. Collection of an endometrial tissue biopsy. MAIN OUTCOME MEASURE(S): RNA extraction, reverse transcription, and determination of gene expression of angiogenesis- and implantation-relevant factors using quantitative polymerase chain reaction. Retrieval of pregnancy information from the medical records. RESULT(S): Good quantity/quality RNA with infertility history was obtained from 63 participating women. Those with a "good" endometrium and subsequent pregnancy showed increased gene expression for placenta growth factor when compared with patients with a "bad" endometrium and who did not succeed with pregnancy to date. Nonpregnant women with a "good" endometrium presented an intermediate result. No significant differences were observed for several other genes tested, but trends in the same direction were observed. CONCLUSION(S): This study demonstrates for the first time that endometrial PLGF expression corresponds to the hysteroscopic appearance of the endometrium, and therefore has potential as a clinically relevant prognosticator for infertility treatment success.

Age-related normograms of serum antimüllerian hormone levels in a population of infertile women: a multicenter study.

OBJECTIVE: To produce age-related normograms for serum antimüllerian hormone (AMH) level in infertile women without polycystic ovaries (non-PCO). DESIGN: Retrospective cohort analysis. SETTING: Fifteen academic reproductive centers. PATIENT(S): A total of 3,871 infertile women. INTERVENTION(S): Blood sampling for AMH level. MAIN OUTCOME MEASURE(S): Serum AMH levels and correlation between age and different percentiles of AMH. RESULT(S): Age-related normograms for the 3rd, 10th, 25th, 50th, 75th, 90th, and 97th percentiles of AMH were produced. We found that the curves of AMH by age for the 3rd to 50th percentiles fit the model and appearance of linear relation, whereas the curves of >75th percentiles fit cubic relation. There were significant differences in AMH and FSH levels and in antral follicle count (AFC) among women aged 24-33 years, 34-38 years, and ≥39 years. Multivariate stepwise linear regression analysis of FSH, age, AFC, and the type of AMH kit as predictors of AMH level shows that all variables are independently associated with AMH level, in the following order: AFC, FSH, type of AMH kit, and age. CONCLUSION(S): Age-related normograms in non-PCO infertile women for the 3rd to 97th percentiles were produced. These normograms could provide a reference guide for the clinician to consult women with infertility. However, future validation with longitudinal data is still needed.

Pregnancy and reproduction in autoimmune rheumatic diseases.

Despite evidence for the important role of oestrogens in the aetiology and pathophysiology of chronic immune/inflammatory diseases, the previous view of an unequivocal beneficial effect of oestrogens on RA compared with a detrimental effect on SLE has to be reconsidered. Likewise, the long-held belief that RA remits in the majority of pregnant patients has been challenged, and shows that only half of the patients experience significant improvement when objective disease activity measurements are applied. Pregnancies in patients with SLE are mostly successful when well planned and monitored interdisciplinarily, whereas a small proportion of women with APS still have adverse pregnancy outcomes in spite of the standard treatment. New prospective studies indicate better outcomes for pregnancies in women with rare diseases such as SSc and vasculitis. Fertility problems are not uncommon in patients with rheumatic disease and need to be considered in both genders. Necessary therapy, shortly before or during the pregnancy, demands taking into account the health of both mother and fetus. Long-term effects of drugs on offspring exposed in utero or during lactation is a new area under study as well as late effects of maternal rheumatic disease on children.

Fertility and cancer: psychological support in young women who contemplate emergency assisted reproductive technologies (ART) prior to chemo- and/or radiation-therapy.

PRINCIPLES: Women of reproductive age with cancer fear for their childbearing potential as a result of the cancer itself and chemo- and/or radiation-therapy. METHODS: Starting in 2006, a dedicated task force was set up at Lausanne University Hospital (CHUV) to handle all cancer and fertility issues and, in certain cases, offer access to emergency assisted reproductive technologies (ART) to preserve further childbearing options. Help provided by the task force was offered within a multidisciplinary framework encompassing psychological counselling offered to each patient or couple. RESULTS: We report here the salient points of the experience gained through dedicated psychological counselling offered to cancer patients concerned about their future fecundity. This was done with the intention of underscoring the most clinically relevant lessons learned through our experience at CHUV. CONCLUSIONS: The specific 'cancer and fertility' counselling instituted at CHUV offers support for young women or couples confronted with stressful cancer and fertility issues. This type of specific counselling, the resource counselling, appears to be a particularly appropriate tool for patients abruptly involved in difficult decision-making processes under time constraints and thus extremely vulnerable. The personal feedbacks from the patients also confirm the importance of offering specific counselling and timely psychological support of the type reported here to all women of reproductive age before starting chemo- and/or radiation-therapy.

Adiponectin isoform distribution in serum and in follicular fluid of women undergoing treatment by ICSI.

OBJECTIVE: Adiponectin is an adipokine, present in the circulation in comparatively high concentrations and different molecular weight isoforms. For the first time, the distribution of these isoforms in serum and follicular fluid (FF) and their usefulness as biological markers for infertility investigations was studied. DESIGN: In vitro study. SETTING: University based hospital. POPULATION AND SAMPLE: Fifty-four women undergoing intracytoplasmic sperm injection (ICSI). METHODS: Oocytes were retrieved, fertilized in vitro using ICSI, and the resulting embryos transferred. Serum was collected immediately prior to oocyte retrieval. Adiponectin isoforms (high molecular weight (HMW), medium and low molecular weight) were determined in serum and FF. Total adiponectin and the different isoform levels were compared with leptin and ovarian steroid concentrations. MAIN OUTCOME MEASURES: Adiponectin isoforms in serum and FF. RESULTS: Adiponectin isoform distribution differed between serum and FF; the HMW fraction made up half of all adiponectin in the serum but only 23.3% in the FF. Total and HMW adiponectin in both serum and FF correlated negatively with the body mass index and the concentration of leptin. No correlations were observed for total adiponectin or its isoforms with estradiol, progesterone, anti-Mullerian hormone, inhibin B, or the total follicle stimulating hormone (FSH) dose administered during the ovarian stimulation phase. CONCLUSIONS: This study shows for the first time that adiponectin isoform distribution varies between the serum and FF compartments in gonadotropin stimulated patients. A trend towards higher HMW adiponectin serum levels in successful ICSI cycles compared to implantation failures was observed; studies with larger patient groups are required to confirm this observation.
