Motives for desiring children among individuals of different sexual-romantic orientations: a cross-sectional study.

PURPOSE: Little is known about the reasoning behind the desire to have children in non-heterosexual individuals. This study compares the motives of different sexual-romantic orientations and their preferred ways of fulfilling this desire. METHODS: This was a monocentric cross-sectional study. Subjects were recruited via social media, personal contacts and queer organisations in Switzerland. An anonymous questionnaire comprised general questions about the participant's background, a validated survey about the desire to have children and additional non-validated questions addressing the impact of sexual-romantic orientation on the desire to have children. The inclusion criteria were adults without children and a completed questionnaire. RESULTS: Of 837 participants, 642 were included in the study. Four groups of sexual-romantic orientations consisted of more than 35 participants: bisexual-biromantic (n = 38), heterosexual-heteroromantic (n = 230), homosexual-homoromantic (n = 159) and pansexual-panromantic (n = 55). Subgroups with a positive wish for a child rated all motives in the same order and with minimal numeric difference. The most important aspect seemed to be emotional involvement. Non-heterosexual-heteroromantic showed concerns about adverse reactions regarding their wish for a child. All orientations hoped for a biological child. CONCLUSION: Our findings about bi-, hetero-, homo- and pansexual people and their motives for a desire to have children agree with the existing literature about hetero, homo and bisexual. The impact of the fear of adverse reaction and discrimination has been discussed before and is supported by our data. We suggest better support before and during the realization of the wish for a child as well as support for non-traditional aspiring parents.

Determinants of transplantation success with cryopreserved ovarian tissue: data from 196 women of the FertiPROTEKT network.

STUDY QUESTION: What are the pregnancy and live birth rates for ovarian tissue transplantation and which factors are associated with the success rate? SUMMARY ANSWER: Pregnancy and live birth rates per transplanted woman are 32.7% and 26.5% and success rate is associated with female age and first versus repeated transplantation. WHAT IS KNOWN ALREADY: Live birth rates after ovarian tissue transplantations have been reported to be between around 24% and 41% per patient. Success rates seem to be negatively associated with increasing female age at the time of tissue cryopreservation and with pelvic radiation. Success rates are apparently not reduced after overnight transportation of ovarian tissue before freezing. STUDY DESIGN, SIZE, DURATION: Registry analysis of 244 transplantations in 196 women, performed by 26 FertiPROTEKT network centres from 2007 to 2019 with follow-up till December 2020. PARTICIPANTS/MATERIALS, SETTING, METHODS: Orthotopic ovarian tissue transplantations were performed in 196 women, 191 with previous malignant and 5 with previous non-malignant diseases. Size of transplanting centres varied between 1 and 100 transplantations per centre (median: 2). Factors possibly associated with success rate such as female age, first and repeated transplantation, experience of the transplanting centre and overnight transportation of the ovarian tissue before freezing were analysed. MAIN RESULTS AND THE ROLE OF CHANCE: Average age of all 196 transplanted women was 31.3 years (SD 5.2; range 17-44) at the time of cryopreservation of tissue and 35.9 years (SD 4.8; range 23-47) at the time of transplantation. Pregnancy rate was 30.6% (95% CI, 24.2-37.6%) per first transplantation and 32.7% (95% CI, 26.1-39.7%) per patient. Pregnancy rate was higher after first transplantation (30.6% (95% CI, 24.2-37.6%)) compared to second and subsequent transplantations (11.8% (95% CI, 3.3-27.5%)). Live birth rate per first transplantation was 25.0% (95% CI, 19.1-31.7%) and per patient 26.5% (95% CI, 20.5-33.3%). Success rate decreased with increasing age at the time of ovarian tissue freezing. Live birth rate was 28.2% (95% CI, 20.9-36.3%) in women <35 years and 16.7% (95% CI, 7.9-29.3%) in women >35 years. Pregnancy rates after first transplantation were higher in centres who had performed ≥10 transplantations (35.1%) compared to centres with <10 transplantation (25.4%) (P = 0.12). Corresponding live birth rates were 27.0% and 18.6%. Success rates were not different in women with and without overnight transportation of tissue before cryopreservation. LIMITATIONS, REASONS FOR CAUTION: The data were drawn from a registry analysis. Data such as ovarian reserve and premature ovarian insufficiency were not available for all women. Data might be influenced by different follow-up policies of the centres. WIDER IMPLICATIONS OF THE FINDINGS: The study reveals the high potential of ovarian tissue freezing and transplantation, but only if freezing is performed in younger women. The study suggests focus should be placed on the first and not on repeated transplantations. It also opens the discussion of whether transplantation should rather be performed by experienced centres. STUDY FUNDING/COMPETING INTEREST(S): No funding. No competing interests. TRIAL REGISTRATION NUMBER: N/A.

Clomiphene citrate stimulated cycles - additional gonadotrophin stimulation increases endometrium thickness without increasing implantation rate.

It is known that Clomiphene citrate (CC) reduces endometrial thickness, but it is unknown if additional gonadotrophin stimulation increases endometrial thickness and if this has an effect on implantation rate in in vitro fertilization (IVF). The retrospective study included 263 minimal stimulation IVF-cycles stimulated with 25 mg CC per day (CC-IVF), and 161 IVF-cycles stimulated with CC plus 75IU hMG (human Menopausal Gonadotrophin) per day (CC/hMG-IVF). Endometrial and oestradiol (E2) measurements were analysed between day -4 and 0 (0 = day of oocyte retrieval) and the association of endometrial thickness and treatment on implantation rates were studied after multiple adjustments. It was shown that on day 0, endometrium was significantly thicker in CC/hMG-IVF versus CC-IVF cycles (9.81 ±2.68 versus 9.06 ±2.54 mm, p = 0.005). However, increased endometrial thickness did not have an effect on implantation and live birth rates. In conclusion, gonadotrophins should not be added to low dose CC treated IVF cycles just to increase endometrial thickness as increased endometrial thickness does not increase implantation rate.

The impact of micronized progesterone on cardiovascular events - a systematic review.

Biologically identical menopausal hormone therapy (MHT) including micronized progesterone (MP) has gained much attention. We aimed to assess the impact of MP in combined MHT on venous and arterial thromboembolism (VTE/ATE) (e.g. deep venous thrombosis/pulmonary embolism, myocardial infarction [MI] and ischemic stroke). Articles were eligible if they provided endpoints regarding cardiovascular events and use of exogenous MP. Literature searches were designed and executed for the databases Medline, Embase, CINAHL, the Cochrane Library, ClinicalTrials.gov and interdisciplinary database Web of Science. Twelve studies consisting of randomized controlled trials (RCTs), case-control studies and prospective or retrospective cohort studies were included, and risk of bias was assessed. Only a minority assessed thromboembolic events as a primary endpoint, showing that in contrast to norpregnane derivatives, primary and recurrent VTE risk was not altered by combining estrogens with MP, which was also true for ischemic stroke risk. Similarly, in placebo-controlled RCTs assessing VTE/ATE as adverse events there were no significant intergroup differences. Studies on MI as a primary endpoint are missing. In conclusion, while available data suggest that MP as a component in combined MHT may have a neutral effect on the vascular system, more RCTs investigating the impact of MP alone or in combined MHT on vascular primary endpoints are needed.

Impact of progesterone on skin and hair in menopause - a comprehensive review.

In clinical practice, micronized progesterone (MP) is frequently recommended to treat signs and symptoms of skin and hair aging in menopausal women. The aim of this comprehensive review was to evaluate whether topically or systemically applied MP may effectively prevent or slow down signs of skin and hair aging. Three out of six identified studies reported an impact of MP on skin aging markers in menopausal women. Of these, two studies reported a benefit: one for topically applied MP, another for systemically applied combined menopausal hormone therapy (MHT) comprising MP as progestogen for endometrial protection. Tolerability and safety of MP were good. However, there was no study investigating the impact of MP on menopausal scalp hair. In conclusion, delay of skin aging comprises lifestyle adjustment, antioxidants, and several esthetic procedures. In menopausal women, MHT displays beneficial effects on skin aging. There is poor quality but promising scientific evidence for MP displaying anti-aging skin effects in menopausal women. However, good quality studies are needed.

Short-term application of ibuprofen before ovulation.

AIM OF THE STUDY: The aim was to analyse if ibuprofen, as a non-selective cyclooxygenase (COX) inhibitor, has any negative effect on oocyte competence and embryo quality. COX- inhibitors are popular over-the-counter analgesics. Whereas selective COX inhibitors have been shown to impair female fertility, data on non-selective COX inhibitors are poor. Hence, they have not been recommended for women trying to conceive. METHODS: This is an observational study comparing ibuprofen exposed and unexposed women from 18 to 42 years of age, using the model of natural cycle in vitro fertilisation (IVF) to determine oocyte and embryo quality. Follicular growth was monitored and if the follicle was mature (≥ 15mm size and estimated oestradiol level of ≥ 800pmol/l), ovulation was triggered. Women with luteinising hormone (LH) surge received 400mg ibuprofen every 8 hours to postpone ovulation, whereas women without LH surge received none (controls). Oocyte retrieval rate, oocyte maturity, fertilization rate, embryo development and embryo quality as well as implantation rate were analysed. RESULTS: Of the 111 women included, 63 received ibuprofen, and 48 did not. Rates of mature oocytes and implantation rate did not differ. Logistic regression showed no significant association of ibuprofen intake, LH- level or reason for infertility on embryo quality. CONCLUSION: Based on our results, we suggest that, particularly within natural cycle IVF, ibuprofen does no harm around ovulation as analgesic treatment.

Follicular flushing leads to higher oocyte yield in monofollicular IVF: a randomized controlled trial.

STUDY QUESTION: Does follicular flushing increase the number of mature oocytes in monofollicular IVF? SUMMARY ANSWER: Follicular flushing increases the number of mature oocytes in monofollicular IVF. WHAT IS KNOWN ALREADY: Flushing increases neither the oocyte yield nor the pregnancy rate in polyfollicular IVF or in poor responder patients. In monofollicular IVF, the effect of flushing has so far been addressed by two studies: (i) a prospective study with minimal stimulation IVF demonstrated an increased oocyte yield, and (ii) a retrospective study with natural cycle (NC)-IVF showed an increased oocyte yield and an increased transfer rate. STUDY DESIGN, SIZE, DURATION: Randomized controlled trial including 164 women who were randomized for either aspiration with or without flushing from 2016 to 2019. PARTICIPANTS/MATERIALS, SETTING, METHODS: Infertile women 18-42 years of age with an indication for IVF treatment at a university-based infertility unit. Women undergoing monofollicular IVF were randomized to either follicular aspiration only or follicular aspiration directly followed by five follicular flushes at a 1:1 ratio. The intervention was done without anaesthesia, using a gauge 19 single-lumen needle. Flushing volume was calculated (sphere formula) based on the size of the follicle. MAIN RESULTS AND THE ROLE OF CHANCE: A total of 164 women were included; 81 were allocated to 'aspiration only' and 83 to additional 'flushing'. Primary analysis was based on the intention-to-treat: oocyte yield, defined as the collected mature oocyte rate, was higher (n = 64/83, 77.1%) in the flushing group compared to the aspiration only group (n = 48/81, 59.3%, adjusted risk difference (RD): 18.2% (95% CI 3.9-31.7%), P-value = 0.02). In the flushing group, most oocytes were retrieved within the first three flushes (63/83, 75.8%). Fertilization rate was higher in the flushing group (n = 53/83, 63.9% vs n = 38/81, 46.9%; adjusted RD: 16.8% (96% CI 1.5-31.4%), P = 0.045). Transfer rate was also higher in the flushing group (n = 52/83, 62.7% vs n = 38/81, 46.9%; RD: 15.71 (95% CI 0.3-30.3%)), but the difference was not significant (P = 0.06). The clinical pregnancy rate n = 9/83 versus n = 9/81 (RD: -0.3% (95% CI -9.9% to 9.5%)) and live birth rate n = 7/83 versus n = 8/81 (RD: -1.5% (95% CI -10.4% to 7.1%)) were not significantly different between the flushing and the aspiration group. The median duration of the intervention was significantly longer with flushing (2.38 min; quartiles 2.0, 2.7) versus aspiration only (0.43 min; quartiles 0.3, 0.5) (P < 0.01). There was no significant difference in the mean (±SD) visual analogue scales pain score between the follicular flushing (3.4 ± 1.8) and the aspiration group (3.1 ± 1.89). LIMITATIONS, REASONS FOR CAUTION: Blinding of the procedure was not possible. WIDER IMPLICATIONS OF THE FINDINGS: Our study proved that flushing of single follicles in NC-IVF increases the oocyte yield. In contrast to polyfollicular IVF flushing seems to be beneficial in a monofollicular setting if the technique used in our study (single-lumen needle, 5 flushings with flushing volume adaptation) is applied. STUDY FUNDING/COMPETING INTEREST(S): The study was funded by the financial sources of the division and in part by a research grant provided by NMS Biomedical SA, Switzerland. The company did not have any roles in design or conduct of the study or in the preparation of the manuscript. The authors have no other conflicts of interest. TRIAL REGISTRATION NUMBER: Clinicaltrials.gov NCT02641808. TRIAL REGISTRATION DATE: 29 December 2015. DATE OF FIRST PATIENT'S ENROLMENT: 22 August 2016.

Serum anti-Müllerian hormone concentration and follicle density throughout reproductive life and in different diseases-implications in fertility preservation.

STUDY QUESTION: How do anti-Müllerian hormone (AMH) serum concentrations and follicle densities (FDs) change with age and disease and what are the implications for fertility preservation? SUMMARY ANSWER: AMH concentrations and FD do not correlate in young women, and AMH but not FD is reduced in some diseases, limiting the value of AMH as a predictive parameter of ovarian tissue transplantation. WHAT IS KNOWN ALREADY: AMH is widely used as a parameter to estimate the ovarian reserve. However, the reliability of AMH to predict total number of follicles and the FD is questionable. Women with lymphoma and leukaemia have been shown to have reduced AMH concentrations, but it is unknown if the FD is also reduced. In fertility preservation it is essential to estimate the correct total number of follicles and the FD, as ovarian tissue should only be cryopreserved if ovarian reserve is high. Furthermore, the amount of tissue to be transplanted should be based on the estimation of the real FD. STUDY DESIGN, SIZE, DURATION: This retrospective observational study included 830 women (mean ± SD age, 28.2 ± 6.81 years; range, 4-43 years) with malignant (n = 806) and benign (n = 24) diseases who cryopreserved tissue in a single centre as part of a national fertility preservation programme. Females with ovarian surgery or known predispositions for a reduced ovarian reserve were excluded. AMH concentrations and FD were evaluated from March 2011 to September 2016. PARTICIPANTS/MATERIALS, SETTING, METHODS: AMH concentrations were analysed before gonadotoxic therapies. Standardized biopsies, obtained from different areas of ovarian cortex, were collected. FD was analysed after tissue digestion and calcein staining and was expressed as average number of primordial and primary follicles count per 3 mm biopsy and per cubic millimeter tissue. AMH concentrations and FD were analysed in relation to age and diagnosis group. Both parameters were age adjusted, and associations between the different diagnosis groups and AMH versus FD were assessed. MAIN RESULTS AND THE ROLE OF CHANCE: Mean ± SD AMH concentration was 3.1 ± 2.81 g/ml, mean FD per 3 mm biopsy was 137 ± 173.9 and 19.4 ± 24.60 per mm3. Maximum AMH concentrations were found in children and teenagers at the age of 6-10 years (5.71 ng/ml) and in adults at the age of 21-25 years (3.33 ng/ml). FD was highest in young children up to an age of 15 years and decreased with increasing age. AMH and FD were not correlated in women ≤20 years and weakly to moderately correlated in women 21-40 years (r = 0.24-0.39). Age-adjusted correlations between AMH and FD were demonstrated in several diagnosis groups such as breast cancer, leukaemia, sarcoma, gastrointestinal cancer and gynaecological cancer but not in the groups exhibiting Hodgkin's and non-Hodgkin's lymphoma, cerebral cancer, other types of malignancies and other types of benign diseases. Further statistical analysis supported the finding that, in some diagnosis groups such as Hodgkin's lymphoma and in gynaecological cancer, AMH concentrations but not FDs are reduced, questioning the prognostic accuracy of AMH for the FD in these diseases. LIMITATIONS, REASONS FOR CAUTION: Even though biopsies were taken from different sites, heterogenous distribution of follicles might have had some effect on the accuracy of the analysis. WIDER IMPLICATION OF THE FINDINGS: AMH should be used with care to estimate the total ovarian reserve and FD of cancer patients in young women in some diseases. Therefore, calculating the amount of ovarian tissue to be transplanted based solely on AMH might be inaccurate whereas FD might be a better parameter. STUDY FUNDING/COMPETING INTEREST(S): The study did not receive any exterior funding.

Effectiveness of seminal plasma in in vitro fertilisation treatment: a systematic review and meta-analysis.

BACKGROUND: With in vitro fertilization (IVF) techniques, only 20-25% of the transferred embryos lead to a pregnancy. OBJECTIVE: To evaluate the beneficial effects of seminal plasma (SP) or semen applied at the time of oocyte aspiration or embryo transfer. SEARCH STRATEGY: Electronic databases were searched from their inception up to August 2017. SELECTION CRITERIA: We included all randomized controlled trials (RCTs) evaluating the effects of SP or semen in IVF treatment. Trials were considered if women were exposed to any kind of SP or semen (either SP/semen injection or sexual intercourse) around the time of oocyte pickup and embryo transfer. DATA COLLECTION AND ANALYSIS: The primary outcome was clinical pregnancy rate (CPR). MAIN RESULTS: Eight RCTs on women undergoing IVF (2128 in total) were included in the meta-analysis. Women randomized in the intervention group had a significantly higher CPR compared with controls (30.0 versus 25.1%; RR 1.20; 95% CI, 1.04-1.39). No significant differences were found in the secondary outcomes, including livebirth rate, biochemical pregnancy, miscarriage, multiple pregnancies, and birth weight. The subgroup analyses (four RCTs, 780 participants), including only those RCTs in which prepared undiluted SP was injected just after oocyte pickup, conformed with the overall analysis for the primary outcome (46.3 versus 37.2%; RR 1.23; 95% CI, 1.05-1.45). CONCLUSION: Because intravaginal or intracervical SP application around the time of oocyte pickup is associated with higher CPR, local application SP may be considered as a potential treatment to improve implantation. TWEETABLE ABSTRACT: SP at the time of oocyte pickup is associated with higher CPR.

Adrenal, thyroid and gonadal axes are affected at high altitude.

Humans cannot live at very high altitude for reasons, which are not completely understood. Since these reasons are not restricted to cardiorespiratory changes alone, changes in the endocrine system might also be involved. Therefore, hormonal changes during prolonged hypobaric hypoxia were comprehensively assessed to determine effects of altitude and hypoxia on stress, thyroid and gonadal hypothalamus-pituitary hormone axes. Twenty-one male and 19 female participants were examined repetitively during a high-altitude expedition. Cortisol, prolactin, thyroid-stimulating hormone (TSH), fT4 and fT3 and in males follicle-stimulating hormone (FSH), luteinizing hormone (LH) and total testosterone were analysed as well as parameters of hypoxemia, such as SaO2 and paO2 at 550 m (baseline) (n = 40), during ascent at 4844 m (n = 38), 6022 m (n = 31) and 7050 m (n = 13), at 4844 m (n = 29) after acclimatization and after the expedition (n = 38). Correlation analysis of hormone concentrations with oxygen parameters and with altitude revealed statistical association in most cases only with altitude. Adrenal, thyroid and gonadal axes were affected by increasing altitude. Adrenal axis and prolactin were first supressed at 4844 m and then activated with increasing altitude; thyroid and gonadal axes were directly activated or suppressed respectively with increasing altitude. Acclimatisation at 4844 m led to normalization of adrenal and gonadal but not of thyroid axes. In conclusion, acclimatization partly leads to a normalization of the adrenal, thyroid and gonadal axes at around 5000 m. However, at higher altitude, endocrine dysregulation is pronounced and might contribute to the physical degradation found at high altitude.

Fertility preservation: ovarian response to freeze oocytes is not affected by different malignant diseases-an analysis of 992 stimulations.

PURPOSE: To study if ovarian response is affected by the type of disease if fertility preservation is required. METHODS: A registry of the trinational fertility preservation network FertiPROTEKT including 992 patients aged 18-40 years undergoing ovarian stimulation and follicle aspiration for fertility preservation from 1/2007 until 3/2016 was analysed. The number of collected oocytes, days of stimulation, total gonadotropin dosage and gonadotropin dosage per day were evaluated. RESULTS: Total oocyte number was negatively correlated with increasing age (r = 0.237, p < 0.0001). Oocyte numbers were in women < 26 years 15.4 ± 8.8, 26-30 years 13.1 ± 8.5, 31-35 years 12.2 ± 7.7 and 36-40 years 9.9 ± 8.0. Age-adjusted oocyte numbers were not different in women with Hodgkin's lymphoma (12.6 ± 8.8), non-Hodgkin's lymphoma (12.4 ± 8.2), leukaemia (11.7 ± 8.2), sarcoma (11.8 ± 8.2), cerebral cancer (16.5 ± 8.1), gastrointestinal cancer (13.2 ± 8.1) gynaecological cancer (10.8 ± 8.2) and other types of malignancies (15.8 ± 8.1) apart from ovarian cancer with lower oocyte yield (7.3 ± 8.3, p < 0.001) compared to women with breast cancer (13.3 ± 8.8). The total gonadotropin dose used for stimulation was only elevated in Hodgkin's and non-Hodgkin's lymphoma compared to women with breast cancer (p < 0.05). Oocyte yield was lower in women with versus without ovarian cancer (p < 0.0001). CONCLUSIONS: As ovarian response is not affected by the type of cancer, ovarian stimulation can be performed with the same oocyte yield in different malignant diseases. However, oocyte yield is reduced if ovarian surgery is required and in older women.

Practical recommendations for fertility preservation in women by the FertiPROTEKT network. Part I: Indications for fertility preservation.

PURPOSE: Most guidelines about fertility preservation are predominantly focused on scientific evidence, but are less practically orientated. Therefore, practically oriented recommendations are needed to support the clinician in daily practice. METHODS: A selective literature search was performed based on the clinical and scientific experience of the authors, focussing on the most relevant diseases and gynaecological cancers. This article (Part I) provides information on topics that are essential for the fertility preservation indication, such as disease prognosis, disease therapy and its associated risks to fertility, recommending disease-specific fertility preservation measures. Part II specifically focusses on fertility preservation techniques. RESULTS: In breast cancer patients, fertility preservation such as ovarian tissue and oocyte cryopreservation is especially recommended in low-stage cancer and in women < 35 years of age. In Hodgkin's lymphoma, the indication is mainly based on the chemotherapy regime as some therapies have very low, others very high gonadotoxicity. In borderline ovarian tumours, preservation of fertility usually is achieved through fertility sparing surgery, ovarian stimulation may also be considered. In cervical cancer, endometrial cancer, rheumatic diseases and other malignancies such as Ewing sarcoma, colorectal carcinoma, non-Hodgkin lymphoma, leukaemia etc., several other factors must be considered to enable an individual, stage-dependent decision. CONCLUSION: The decision for or against fertility preservation depends on the prognosis, the risks to fertility and individual factors such as prospective family planning.

Measuring Active and Healthy Ageing: Applying a GENERIC Interdisciplinary Assessment Model Incorporating ICF.

OBJECTIVES: In this study we compared the chronological and bio-functional age between two German speaking cohorts 30 years apart applying a comprehensive and generic Active and Healthy Aging (AHA) assessment model incorporating ICF. METHODS: Single-centre, cross-sectional, observational, non-interventional, non-randomized trial at an University based women's hospital, division of Gynecological Endocrinology and Reproductive Medicine. All participants followed a standardized, holistic battery of biopsychosocial assessments consisting of bio-functional status (BFS), bio-functional age (BFA) and additional validated psychometric questionnaires. RESULTS: 462 non-pediatric, non-geriatric females were in the BeCS-14 cohort. The measured mean BFA was lower than the chronological age within the BeCS-14 cohort (regression coefficient 0.58) and comparable in the female LeCS-84 subcohort (regression coefficient age 0.85, communality age 76%). In detail, within the decades 35-45 years and 55-65 years the gradient of BFA increase (aging rate) was similar in both cohorts (decade 35-45 years: LeCS-84 4.08 ± 1.03 year equivalents and BeCS-14 4.78 ± 1.67 year equivalents; decade 55-65 years: LeCS-84 6.21 ± 1.29 year equivalents and BeCS-14 5.25 ± 1.18 year equivalents). Remarkably, within the LeCS-84 cohort the mean aging rate within the decade 45-55 years was significantly different from all other aging rates in both cohorts: 13.02 ± 1.05 year equivalents. However, within the BeCS-14 cohort the corresponding value was 4.83 ± 1.02 year equivalents thus indicating a continuous aging process across the adult life course. In BeCS-14, there was a significant age-related effect for cardiovascular performance and social stress exposition and younger age was associated with better cardiovascular performance while level of social stress exposition decreased in aging women. CONCLUSION: When comparing BeCS-14 and LeCS-84, the aging process seemed to be accelerated in women in LeCS-84 between 45 and 54 years of age. We can only speculate on the reasons, such as differences in the health care, political and social system. However, the differences observed support the use of our BFS/BFA assessment tool not only on an individual level (strengths/resources) but also population level following EIP-AHA requirements. Yet, it remains to be developed how the assessed health strengths/resources-profile may be integrated into AHA management.

Fertility preservation issues in pediatric hematopoietic stem cell transplantation: practical approaches from the consensus of the Pediatric Diseases Working Party of the EBMT and the International BFM Study Group.

Fertility preservation is an urgent challenge in the transplant setting. A panel of transplanters and fertility specialists within the Pediatric Diseases Working Party of the European Society for Blood and Marrow Transplantation (EBMT) and the International BFM Study Group provides specific guidelines. Patients and families should be informed of possible gender- and age-specific cryopreservation strategies that should be tailored according to the underlying disease, clinical condition and previous exposure to chemotherapy. Semen collection should be routinely offered to all postpubertal boys at the diagnosis of any disease requiring therapy that could potentially impair fertility. Testicular tissue collection might be offered to postpubertal boys; nevertheless, its use has been unsuccessful to date. Oocyte collection after hormonal hyperstimulation should be offered to postpubertal girls facing gonadotoxic therapies that could be delayed for the 2 weeks required for the procedure. Ovarian tissue collection could be offered to pre-/post-pubertal girls. Pregnancies have been reported after postpubertal ovarian tissue reimplantation; however, to date, no pregnancy has been reported after the reimplantation of prepubertal ovarian tissue or in vitro maturation of pre-/post-pubertal ovarian tissue. Possible future advances in reproductive medicine could change this scenario. Health authorities should prioritize fertility preservation projects in pediatric transplantation to improve patient care and quality of life.

Follicular flushing in natural cycle IVF does not affect the luteal phase - a prospective controlled study.

In contrast to multifollicular IVF, follicular flushing seems to increase the efficacy of monofollicular IVF treatments such as natural cycle IVF (NC-IVF). However, because follicular flushing causes loss of granulosa cells, it might negatively affect luteal phase length and endocrine function of the luteal body. A prospective cohort Phase II study was performed in 24 women undergoing NC-IVF. Women underwent a reference cycle with human chorionic gonadotrophin-induced ovulation without follicle aspiration and analysis of the length of the luteal phase and luteal concentrations of progesterone and oestradiol. In addition, they underwent a NC-IVF cycle which was performed identically but follicles were aspirated and flushed three times. The luteal phase was shorter in 29.2%, equal in 16.7% and longer in 50.0% of cases following flushing of the follicles. Overall, neither difference in luteal phase length was significant [median duration (interquartile range) in reference cycle: 13 (12; 14.5), IVF (flushing) cycle: 14 (12.5; 14.5), median difference (95% CI): 0.5 (-0.5 to 1.5)] nor median progesterone and oestradiol concentrations. In conclusion, follicular flushing in NC-IVF affects neither the length of the luteal phase nor the luteal phase concentrations of progesterone and oestradiol, questioning the need for luteal phase supplementation.

Two-year development of children conceived by IVM: a prospective controlled single-blinded study.

STUDY QUESTION: Is there a difference in mental development of children conceived by IVM in comparison to IVF or ICSI, independently, at the age of 2 years? SUMMARY ANSWER: No differences could be found in mental development of IVM children compared to IVF and IVM children compared to ICSI as well. WHAT IS KNOWN ALREADY: Only few retrospective or non-controlled studies addressed the health of IVM children and did not show a negative impact of the IVM procedure. STUDY DESIGN, SIZE, DURATION: Prospective controlled single-blinded study including 63 pregnancies (21 per IVM, IVF and ICSI groups) with 70 children expected. Examinations of 62 embryos at first trimester screening, of 57 fetuses at 21st week of pregnancy, of 60 children at birth and of 37 children at their second birthday were performed during the study period from January 2009 until October 2016. Bayley score at the age of 2 was the primary outcome parameter. Data of 40 children after spontaneous conception from a previous prospective unrelated study were further used as control at 2 years examination and compared to the pooled ART group (IVM, IVF and ICSI). PARTICIPANTS/MATERIALS, SETTING, METHODS: Twenty-one IVM pregnancies achieved in the study period were included. For each of them, the following IVF- and ICSI pregnancies were recruited as controls. Ultrasound examinations during pregnancy, examinations of newborns and of children around their second birthday were done by blinded prenatal specialists, pediatricians and neuropediatricians, respectively. MAIN RESULTS AND THE ROLE OF CHANCE: Children conceived after IVM did not show differences during embryonic development, at birth nor in their neuropediatric development at the age of 2 compared to their counterparts after IVF and after ICSI (Bayley score 91.3 ± 21.0 for IVM, 96.8 ± 13.2 for IVF and 103.9 ± 13.1 for ICSI) and of the pooled ART group compared to children after spontaneous conception (96.6 ± 16.4 ART and 103.2 ± 9.4 spontaneous conception). When analyzing singleton pregnancies only, again no differences during pregnancy, at birth and at their 2-year evaluation were detected between IVM versus IVF and IVM versus ICSI. LIMITATIONS, REASONS FOR CAUTION: Due to the small sample size data must be interpreted with caution. To allow a confirmative answer that there are no health risks for children conceived by IVM, large multicenter cohort or registry-based studies are urgently needed. WIDER IMPLICATIONS OF THE FINDINGS: The study adds further information to previous uncontrolled or retrospective studies, which were unable to detect risks for the health of IVM children. STUDY FUNDING/COMPETING INTEREST(S): The study was supported by the 'Deutsche Forschungsgemeinschaft' (DFG): STR 387/4-1. G.R. receives royalties from Pearson Assessment Germany (editor fee for Bayley-III). The other authors have no conflicts of interest to declare. TRIAL REGISTRATION NUMBER: Not applicable.

State-of-the-art fertility preservation in children and adolescents undergoing haematopoietic stem cell transplantation: a report on the expert meeting of the Paediatric Diseases Working Party (PDWP) of the European Society for Blood and Marrow Transplantation (EBMT) in Baden, Austria, 29-30 September 2015.

Nowadays, allogeneic haematopoietic stem cell transplantation (allo-HSCT) is a well-established treatment procedure and often the only cure for many patients with malignant and non-malignant diseases. Decrease in short-term complications has substantially contributed to increased survival. Therefore long-term sequelae are reaching the focus of patient care. One of the most important risks of stem cell transplant survivors is infertility. As well as in the field of allo-HSCT also the field of reproductive medicine has achieved substantial advances to offer potential options for fertility preservation in both boys and girls. Access to these procedures as well as their financing differs significantly throughout Europe. As all European children and adolescents should have the same possibility, the Paediatric Diseases Working Party of the European Society for Blood and Marrow Transplantation organised an expert meeting in September 2015. This manuscript describes the recommendations for the diagnosis and pre-emptive procedures that should be offered to all children and adolescents in Europe who have to undergo an allo-HSCT.
