RESUMEN

Purpose The aim of this guideline is to standardize the diagnosis and therapy of recurrent miscarriage (RM) using evidence from the recent literature. This is done by using consistent definitions, objective evaluations and standardized treatment protocols. Methods When this guideline was compiled, special consideration was given to previous recommendations in prior versions of this guideline and the recommendations of the European Society of Human Reproduction and Embryology, the Royal College of Obstetricians and Gynecologists, the American College of Obstetricians and Gynecologists and the American Society for Reproductive Medicine, and a detailed individual search of the literature about the different topics was carried out. Recommendations Recommendations about the diagnostic and therapeutic procedures offered to couples with RM were developed based on the international literature. Special attention was paid to known risk factors such as chromosomal, anatomical, endocrinological, physiological coagulation, psychological, infectious and immune disorders. Recommendations were also developed for those cases where investigations are unable to find any abnormality (idiopathic RM).

RESUMEN

The aspects of fertility preservation in women prior to surgical, gonadotoxic or radiation therapy represent a challenging topic in many disciplines and often in an interdisciplinary setting. Within an often short period of time, individual counselling and consideration must be given as to whether fertility-protective measures are useful. The implementation is ultimately decided by the patient. A prerequisite for helpful counselling is knowledge about the potential effects of cancer treatment on ovarian function as well as the implementation and potential individual benefits of fertility-protective measures. Networks such as FertiPROTEKT Netzwerk e. V. are helpful for orientation in terms of content and timely implementation of counselling and corresponding measures.

RESUMEN

Sometimes, for medical reasons, when a frozen tissue has already thawed, an operation by re-transplantation may be cancelled, and ovarian tissues should be re-frozen for transplantation next time. Research about the repeated cryopreservation of ovarian cells is rarely reported. It has been published that there is no difference in the follicle densities, proportions of proliferation of early preantral follicles, appearance of atretic follicles, or ultrastructural quality of frozen-thawed and re-frozen-rethawed tissue. However, the molecular mechanisms of a repeated cryopreservation effect on the developmental potential of ovarian cells are unknown. The aim of our experiments was to investigate the effect of re-freezing and re-thawing ovarian tissue on gene expression, gene function annotation, and protein-protein interactions. The morphological and biological activity of primordial, primary, and secondary follicles, aimed at using these follicles for the formation of artificial ovaries, was also detected. Second-generation mRNA sequencing technology with a high throughput and accuracy was adopted to determine the different transcriptome profiles in the cells of four groups: one-time cryopreserved (frozen and thawed) cells (Group 1), two-time cryopreserved (re-frozen and re-thawed after first cryopreservation) cells (Group 2), one-time cryopreserved (frozen and thawed) and in vitro cultured cells (Group 3), and two times cryopreserved (re-frozen and re-thawed after first cryopreservation) and in vitro cultured cells (Group 4). Some minor changes in the primordial, primary, and secondary follicles in terms of the morphology and biological activity were detected, and finally, the availability of these follicles for the formation of artificial ovaries was explored. It was established that during cryopreservation, the CEBPB/CYP19A1 pathway may be involved in regulating estrogen activity and CD44 is crucial for the development of ovarian cells. An analysis of gene expression in cryopreserved ovarian cells indicates that two-time (repeated) cryopreservation does not significantly affect the developmental potential of these cells. For medical reasons, when ovarian tissue is thawed but cannot be transplanted, it can be immediately re-frozen again.

RESUMEN

INTRODUCTION: The decision, whether to undergo fertility preservation or not is highly demanding for cancer patients. Decision aids may act as an additional source of support. So far, only a limited number of decision aids regarding fertility preservation for female cancer patients exist and have been evaluated systematically. This paper presents the results of secondary analyses of the first randomized controlled trial evaluating an online decision aid for female cancer patients affected by different types of cancer. It focuses on fertility-related knowledge, attitude toward fertility preservation, and long-term effectiveness regarding decisional regret. MATERIAL AND METHODS: Young female cancer patients between 18 and 40 years of age were recruited after fertility counseling with a reproductive specialist. They were assigned to either the control group (counseling only) or the intervention group (counseling followed by the additional use of the decision aid). Both groups had to complete a questionnaire after counseling as well as 1 and 12 months later, covering topics such as fertility-related knowledge, attitude towards fertility preservation, decisional conflict and regret. Recruitment was ongoing during 18 months in eight fertility centers located in Switzerland and Germany. RESULTS: Mean age of participating women was 29.31 years (SD 4.57). Of the entire sample (n = 51) 53% were affected with breast cancer, 27.4% with lymphoma, and 19.6% with various other types of cancer. Knowledge regarding the most common fertility preservation methods was high and comparable in both groups. Positive attitude significantly exceeded negative attitude among all participants (p = 0.001). Although the altogether low scores for decisional regret were on a higher level in the control group (T2: mean = 19.00, SD = 13.24; T3: mean = 22.0, SD = 20.67) than in the intervention group (T2: mean = 14.12, SD = 11.07; T3: mean = 12.94, SD = 13.24), there were no statistically significant differences between and within both groups. There was a positive association between decisional conflict and decisional regret at T3 (p = 0.001, r = 0.510). CONCLUSIONS: This decision aid was suitable as an additional source of knowledge and may positively impact decisional regret in the long term. Results suggest that the provision of an online decision aid as a complement to fertility counseling may facilitate decision-making.

RESUMEN

Objective: Turner syndrome (TS) is characterized by complete or partial loss of one sex chromosome and is commonly associated with short stature, metabolic changes (such as central obesity, abnormal glucose tolerance and high triglycerides) and premature ovarian insufficiency (POI). Primary management of TS during childhood and adolescence comprises treatment with human growth hormone (hGH) and, in cases with early loss of ovarian function, hormone replacement therapy (HRT). Given that metabolic parameters are altered when HRT is applied during menopause, we analyzed whether metabolic changes might be positively or negatively affected within 10 years after HRT and/or hGH in girls with TS. Design: Observational study. Methods: Data were collected from the medical records of 31 girls with TS attending two endocrinologic centers in Germany between 2000 and 2020. Descriptive statistics are reported as the mean ± SEM or percentages. Results: The mean age at first presentation was 99.06 ± 8.07 months, the mean height was 115.8 ± 3.94 cm, and the mean BMI 19.0 ± 0.99 was kg/m2. Treatment with hGH was given to 96.8% of the girls, starting at an average age of 99.06 ± 8.70 months, and was continued for 67.53 ± 6.28 months. HRT was administered to 80.6% of all patients and was started at a mean age of 164.4 ± 4.54 months. During the follow-up, we did not observe any significant absolute changes in lipid parameters, but we detected beneficial effects of childhood hGH: significantly lower cholesterol (-0.206/month; p = 0.006), lower low density lipoprotein cholesterol (-0.216/month; p = 0.004), and higher high density lipoprotein cholesterol (+0.095/month; p = 0.048). Insulin concentrations, showed a significant increase attributable to hGH treatment (+0.206/month; p = 0.003), which was ameliorated by concomitant or subsequent HRT (-0.143/month; p = 0.039). Conclusion: Treatment with hGH and HRT is provided to most girls with TS. Metabolic effects are associated with both modalities. Monitoring of metabolic changes appears to be important to detect unfavorable effects, and could guide treatment adjustment and duration.

RESUMEN

Fertility preservation in women with Turner syndrome is highly controversial. Some strongly recommend freezing of ovarian tissue at a young age, others do not. The controversy is partly due to different perspectives and professions. Biologists prefer to freeze young ovaries with high follicle density, reproductive physicians want to avoid risky operations and iatrogenic infertility by removing one ovary, and cardiologists and obstetricians warn against the risks of later pregnancies. Accordingly, fertility preservation in young women with Turner syndrome is more than just the freezing of ovarian tissue or oocytes. Fertility preservation requires a balanced decision considering the conservation of fertility, the protection of reproductive health, and future health consequences. Therefore, fertility preservation strategies should be based not only on the individual ovarian reserve but also on the genotype and the expected cardiac health status to decide what is the best option: to freeze tissue or alternatively to wait and see.

RESUMEN

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.

RESUMEN

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. The aim of this guideline is to provide physicians with evidence-based recommendations for counselling, diagnosis 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 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.

RESUMEN

STUDY QUESTION: Does the use of an online decision aid (DA) about fertility preservation (FP), in addition to standard counselling by a specialist in reproductive medicine, reduce decisional conflict compared to standard counselling alone? SUMMARY ANSWER: Female cancer patients who could make use of the online DA had a significantly lower short-term decisional conflict score. WHAT IS KNOWN ALREADY: Nowadays, female cancer patients have several options for preserving fertility, but having to decide whether to opt for FP within a short time frame after cancer diagnosis and before the start of treatment is challenging. According to previous studies focussing mainly on breast cancer patients, decisional conflict among these women is high, and they have expressed the need for additional support. STUDY DESIGN, SIZE, DURATION: The study was a randomized controlled trial including female cancer patients who were referred by their treating oncologist to a specialist in reproductive medicine for fertility counselling. Participants were randomly assigned to the control group (counselling only) or to the intervention group (counselling and additional use of the online DA immediately after counselling). Recruitment was ongoing from July 2016 to December 2017 at eight fertility centres in Switzerland and Germany. PARTICIPANTS/MATERIALS, SETTING, METHODS: The online DA was developed by an interdisciplinary team of specialists in reproductive medicine, gynaecologists, oncologists and psychologists. Of 79 recruited participants, 59 completed the first assessment and could therefore be enrolled in the study. They were asked to complete an online questionnaire at three time points: at T1, after counselling (control group, n = 27) or after counselling and the additional use of the DA (intervention group, n = 24); at T2, 1 month later (N = 41: control group, n = 23; intervention group, n = 18); and at T3, 12 months later (N = 37: control group, n = 20; intervention group, n = 17). The survey comprised questions about fertility-related knowledge, attitude towards FP, willingness to undergo FP and socio-demographic data, as well as the decisional conflict and decisional regret scales. MAIN RESULTS AND THE ROLE OF CHANCE: All participants showed low decisional conflict scores. Women who used the online DA in addition to counselling (intervention group) showed a significantly lower total score on the Decisional Conflict Scale (DCS) compared to the control group at T1 (P = 0.008; M = 12.15, SD = 4.38; 95% CI, 3.35-20.95) and at T2 (P = 0.043; M = 9.35, SD = 4.48; 95% CI, 0.31-18.38). At T3, the mean total score of the DCS was still lower in the intervention group compared to the control group; however, this group difference was no longer significant (P = 0.199, M = 6.86, SD = 5.24; 95% CI, -3.78 to 17.51). The majority of participants had already made a decision regarding FP (yes or no) at T1 (72.5%): 91.7% in the intervention group compared to 55.6% in the control group (P = 0.014). Those who had decided already at T1 showed significantly lower decisional conflict (P = 0.007; M = 13.69, SD = 4.89; 95% CI, 3.86-23.52). The average number of DA sessions per user was 2.23, and 80.8% of the participants completed the DA's value clarification exercises. Participants in the intervention group were satisfied with the DA and would recommend it to other patients. LIMITATIONS, REASONS FOR CAUTION: The recruitment of participants was challenging because of the emotionally difficult situation patients were in. This led to the limited sample size for final analysis. Education levels were high in two-thirds of the participants. It is difficult to say whether the DA would be equally effective in women with a lower educational background. WIDER IMPLICATIONS OF THE FINDINGS: There is evidence that the DA served as a helpful complement to the decision-making process for young female cancer patients qualifying for FP. This is, to our knowledge, the first randomized controlled trial evaluating a DA targeted at patients with several cancer types and in a language other than English (i.e. German). This study contributes to extending the range of the still limited number of DAs in the context of FP. STUDY FUNDING/COMPETING INTEREST(S): The study was supported by a research grant of the Swiss Cancer Research. The authors declare that no competing interests exist. TRIAL REGISTRATION NUMBER: Clinicaltrials.gov, trial no. NCT02404883. TRIAL REGISTRATION DATE: 19 March 2015. DATE OF FIRST PATIENT'S ENROLMENT: 4 July 2016.

RESUMEN

Fertility preservation is an increasingly important discipline. It requires close coordination between reproductive medicine specialists, reproductive biologists, and oncologists in various disciplines. In addition, it represents a particular health policy challenge, since fertility-protection measures are to be understood as a treatment for side effects of gonadotoxic treatments and would therefore normally have to be reimbursed by health insurance companies. Therefore, it is inevitable that fertility-preservation activities should organise themselves into a network structure both as a medical-logistic network and as a professional medical society. The necessary network structures can differ significantly at regional, national, and international level, as the size of the regions to be integrated and the local cultural and geographical conditions, as well as the political conditions are very different. To address these issues, the current review aims to point out the basic importance and the chances but also the difficulties of fertility-protection networks and give practical guidance for the development of such network structures. We will not only discuss network structures theoretically but also present them based on three established, different sized networks, such as the Danish Network (www.rigshospitalet.dk), representing a centralised network in a small country; the German-Austrian-Swiss network FertiPROTEKT® (www.fertiprotekt.com), representing a centralised as well as decentralised network in a large country; and the Oncofertility® Consortium (www.oncofertility.northwestern.edu), representing a decentralised, internationally oriented network, primarily serving the transfer of knowledge among its members.

RESUMEN

AIM: The aim of this official guideline published by the German Society of Gynecology and Obstetrics (DGGG) and coordinated with the German Society of Urology (DGU) and the German Society of Reproductive Medicine (DGRM) is to provide consensus-based recommendations, obtained by evaluating the relevant literature, on counseling and fertility preservation for prepubertal girls and boys as well as patients of reproductive age. Statements and recommendations for girls and women are presented below. Statements or recommendations for boys and men are not the focus of this guideline. METHODS: This S2k guideline was developed at the suggestion of the guideline commission of the DGGG, DGU and DGRM and represents the structured consensus of representative members from various professional associations (n = 40). RECOMMENDATIONS: The guideline provides recommendations on counseling and fertility preservation for women and girls which take account of the patient's personal circumstances, the planned oncologic therapy and the individual risk profile as well as the preferred approach for selected tumor entities.

RESUMEN

PURPOSE: Official guideline of the German Society of Gynecology and Obstetrics (DGGG), the Austrian Society of Gynecology and Obstetrics (ÖGGG) and the Swiss Society of Gynecology and Obstetrics (SGGG). The aim of this guideline was to standardize the diagnosis and treatment of couples with recurrent miscarriage (RM). Recommendations were based on the current literature and the views of the involved committee members. METHODS: Based on the current literature, the committee members developed the statements and recommendations of this guideline in a formalized process which included DELPHI rounds and a formal consensus meeting. RECOMMENDATIONS: Recommendations for the diagnosis and treatment of patients with RM were compiled based on the international literature. Specific established risk factors such as chromosomal, anatomical, endocrine, hemostatic, psychological, infectious and immunological disorders were taken into consideration.

RESUMEN

PURPOSE: Impairment of fertility is a common sequela of successful cancer treatment. Therefore, fertility preservation (FP) should be discussed with all young cancer patients. Decisions about FP are challenging. Patients wish more specific support and the first results concerning the helpfulness of decision aids (DA) were promising. Aside from describing the process of development and the content of an online DA in German, the objective of this study was to pilot test users' satisfaction with the DA and its effect on knowledge about FP and decisional conflict (DC). METHODS: In this prospective consecutive study, a control group (n = 20, fertility counseling) was followed by and compared with an intervention group (n = 20, counseling and additional use of the DA, developed by an interdisciplinary team) of recently diagnosed female cancer patients between 18 and 40 years. RESULTS: Nearly all participants who applied the DA considered it helpful for decision-making and recommendable. Knowledge about FP was high with regard to FP techniques women went for. DC was moderate according to the mean score (M = 27.92, standard deviation = 13.27) and only in 20%, the score was above the threshold for high DC. There was no difference between the control and intervention group for knowledge and DC. CONCLUSION: The DA seems to serve as additional and well-accepted support tool in decision-making for patients and professionals. Referral to a reproductive specialist is crucial to warrant comprehensive information. These results need to be confirmed with the current ongoing randomized controlled study.

RESUMEN

OBJECTIVE: What are the patients attitudes about their fertility and about the counselling process at the time when fertility preservation counselling is performed? STUDY DESIGN: A survey regarding fertility concerns and counselling performance in relation to the chosen fertility preservation procedure such as no treatment, GnRH agonists, and freezing of ovarian tissue or oocytes/zygotes was prospectively conducted in four university centres and one private centre, all belonging to the network FertiPROTEKT in Germany and Switzerland. RESULTS: All women (n=145) received a questionnaire at the first counselling appointment. The mean age of the patients was 30 years (±5.8, range 17-43 years). 91% were referred by their treating oncologists. Single patients preferred invasive strategies, such as freezing of oocytes/zygotes (44.3%) or freezing of ovarian tissue (36%), whereas only 19.7% opted for no treatment/GnRH agonists. In married couples, the proportions were 28.9%, 31.1% and 40.0% respectively. Women without children also opted more frequently for invasive strategies, such as freezing of oocytes/zygotes (84.5%) or freezing of ovarian tissue (74.1%), and less frequently for no treatment/GnRH agonists (63.3%). Physical and psychological status, current and future fertility concerns and satisfaction with the counselling process were equal in all treatment groups. CONCLUSION: As fertility concerns and attitudes about the counselling process were independent from the fertility preservation procedure chosen, the preferred treatment can hardly be predicted and therefore all women should be counselled about all possible fertility preservation techniques.

RESUMEN

Fertility-preservation techniques for medical reasons are increasingly offered in national networks. Knowledge of the characteristics of counselled patients and techniques used are essential. The FertiPROTEKT network registry was analysed between 2007 and 2013, and included up to 85 university and non-university centres in Germany, Austria and Switzerland; 5159 women were counselled and 4060 women underwent fertility preservation. In 2013, fertility-preservation counselling for medical reasons increased significantly among nullipara and women aged between 21 and 35 years (n = 1043; P < 0.001). Frequency of GnRH applications slowly decreased, whereas tissue, oocytes and zygote cryopreservation increased. In 2013, women with breast cancer mainly opted for tissue freezing, whereas women with lymphoma opted for GnRH agonist. Women younger than 20 years predominantly opted for GnRH agonists and ovarian tissue cryopreservation; women aged between 20 and 40 years underwent a variety of techniques; and women over 40 years opted for GnRH agonists. The average number of aspirated oocytes per stimulation cycle decreased as age increased (< 30 years: 12.9; 31-35 years: 12.3; 36-46: 9.0; > 41 years: 5.7). For ovarian tissue cryopreservation, removal and cryopreservation of fewer than one ovary was preferred and carried out in 97% of cases in 2013.

RESUMEN

This prospective, noninterventional, post-marketing surveillance study evaluated doses of recombinant human follicle-stimulating hormone (r-hFSH) using the redesigned follitropin alfa pen in women who were anovulatory or oligomenorrheic and undergoing ovulation induction (OI) alone or OI with intrauterine insemination. The primary endpoint was the proportion of patients who achieved monofollicular or bifollicular development (defined as one or two follicles ≥15 mm). Secondary endpoints included characteristics of ovulation stimulation treatment, such as mean total and mean daily r-hFSH doses. Data were analyzed for 3,193 patients from 30 German fertility centers. The proportion of patients with monofollicular or bifollicular development was 71.1% (n=2,270 of a total of 3,193 patients; intent-to-treat population). The mean±standard deviation total and daily doses of r-hFSH were 696.9±542.5 IU and 61.7±29.4 IU, respectively. The three doses prescribed most frequently were: 37.5 IU (n=703 from N=3,189; 22.0%), 50.0 IU (n=1,056 from N=3,189; 33.1%), and 75.0 IU (n=738 from N=3,189; 23.1%) on the first day of stimulation; and 37.5 IU (n=465 from N=3,189; 14.6%), 50.0 IU (n=922 from N=3,189; 28.9%), and 75.0 IU (n=895 from N=3,189; 28.1%) on the last day of stimulation. This noninterventional, post-marketing surveillance study found that monofollicular or bifollicular development was achieved in 71% of patients studied and the small dose increment (12.5 IU) of the redesigned follitropin alfa pen allowed individualized treatment of women undergoing OI.

RESUMEN

BACKGROUND: Fertility-preserving measures for women are increasingly being performed for non-medical reasons in Germany. This is now a controversial matter. METHODS: The authors searched the PubMed database for pertinent publications on the basis of their clinical and scientific experience and evaluated relevant data from the registry of the German FertiPROTEKT network (www.fertiprotekt. com). The various fertility-preserving measures that are available are described and critically discussed. RESULTS: In most cases, the creation of a fertility reserve currently involves the cryopreservation of unfertilized oocytes, rather than of ovarian tissue. Most of the women who decide to undergo this procedure are over 35 years old. According to data from the FertiPROTEKT registry, most such procedures carried out in the years 2012 and 2013 involved a single stimulation cycle. The theoretical probability of childbirth per stimulation is 40% in women under age 35 and 30% in women aged 35 to 39. If the oocytes are kept for use at a later date, rather than at once, the maternal risk is higher, because the mother is older during pregnancy. The risk to the child may be higher as well because of the need for in vitro fertilization (IVF). Pregnancy over age 40 often leads to complications such as gestational diabetes and pre-eclampsia. IVF may be associated with a higher risk of epigenetic abnormalities. Ethicists have upheld women's reproductive freedom while pointing out that so-called social freezing merely postpones social problems, rather than solving them. CONCLUSION: Fertility preservation for non-medical reasons should be critically discussed, and decisions should be made on a case-by-case basis.

RESUMEN

Improved possibilities to protect and preserve fertility before gonadotoxic therapies allow us to help more women than in previous years. But to individually decide which preserving option and concept is possible and useful, one needs time for an intensive fertility preservation consultation. The counselling should be performed as soon as possible after having an exact diagnosis, an idea about the planned oncological adjuvant or neoadjuvant therapy and its potential toxicity on ovaries. After the fertility preservation consultation, patients must have enough time to decide and involved colleagues must have enough time to realize the individual concept after patients' decision.
