Cíl: Popsat strategie zvládání stresu (coping) a prožívaný stres v souvislosti s neplodností u mužů a žen podstupujících léčbu in vitro fertilizace (IVF). Zjistit, zda jsou mezi ženami a muži rozdíly v prožívání a zároveň vytipovat adaptivní a neadaptivní strategie pro zvládání neplodnosti. Soubor a metoda: Korelační studie, 162 pacientů s primární neplodností (99 žen a 63 mužů), kteří podstupovali léčbu IVF v Sanus Pardubice, vyplnilo psychologické dotazníky Fertility Problem Inventory a COPE Inventory. Výsledky: Mezi muži a ženami nebyl nalezen statisticky významný rozdíl v míře prožívaného stresu. Nejčastěji užívali muži i ženy copingové strategie pozitivní reinterpretace, plánování a akceptace, muži užívali signifikantně častěji než ženy strategii zdrženlivost, potlačení a plánování, ženy užívaly signifikantně častěji než muži strategie využívání emoční sociální opory a náboženský coping. U žen i mužů signifikantně korelovala s celkovou mírou prožívaného stresu strategie popření v pozitivním směru, strategie pozitivní reinterpretace a akceptace v negativním směru. Závěr: Nedobrovolně bezdětné ženy a muži v léčbě IVF prožívají podobný stres, užívají ale mírně odlišné copingové strategie. Pro muže i ženy se jako adaptivní copingové strategie ukazují pozitivní reinterpretace a akceptace, jako neadaptivní popření.

Aim: To describe coping strategies and infertility stress in men and women undergoing in vitro fertilization (IVF) treatment. To determine whether there are differences in coping strategies between men and women and to identify adaptive and non-adaptive coping strategies for infertility. Materials and methods: A correlational study, where 162 patients (99 women and 63 men) with primary infertility undergoing IVF treatment at Sanus Pardubice completed the Fertility Problem Inventory and COPE Inventory psychological questionnaires. Results: There were no significant differences between women and men in experiencing infertility stress. The coping strategies used most frequently by both men and women were Positive Reinterpretation, Planning, and Acceptance; men used the strategies Restraint, Suppression, and Planning significantly more frequently than women; and women used the strategies Using Emotional Social Support and Religious Coping significantly more frequently than men. For both women and men, level of Global infertility stress significantly correlated with Denial in the positive direction and with Positive Reinterpretation and Acceptance in the negative direction. Conclusion: Involuntarily childless women and men in IVF treatment experience similar infertility stress, but use slightly different coping strategies. For both men and women, Positive Reinterpretation and Acceptance emerged as adaptive strategies, while Denial emerged as non-adaptive.

STUDY QUESTION: Which actively translated maternal transcripts are differentially regulated between clinically relevant in vitro and in vivo maturation (IVM) conditions in mouse oocytes and zygotes? SUMMARY ANSWER: Our findings uncovered significant differences in the global transcriptome as well as alterations in the translation of specific transcripts encoding components of energy production, cell cycle regulation, and protein synthesis in oocytes and RNA metabolism in zygotes. WHAT IS KNOWN ALREADY: Properly regulated translation of stored maternal transcripts is a crucial factor for successful development of oocytes and early embryos, particularly due to the transcriptionally silent phase of meiosis. STUDY DESIGN, SIZE, DURATION: This is a basic science study utilizing an ICR mouse model, best suited for studying in vivo maturation. In the treatment group, fully grown germinal vesicle oocytes from stimulated ovaries were in vitro matured to the metaphase II (MII) stage either as denuded without gonadotropins (IVM DO), or as cumulus-oocyte complexes (IVM COC) in the presence of 0.075 IU/ml recombinant FSH (rFSH) and 0.075 IU/ml recombinant hCG (rhCG). To account for changes in developmental competence, IVM COC from non-stimulated ovaries (IVM COC-) were included. In vivo matured MII oocytes (IVO) from stimulated ovaries were used as a control after ovulation triggering with rhCG. To simulate standard IVM conditions, we supplemented media with amino acids, vitamins, and bovine serum albumin. Accordingly, in vitro pronuclear zygotes (IMZ) were generated by IVF from IVM DO, and were compared to in vivo pronuclear zygotes (IVZ). All experiments were performed in quadruplicates with samples collected for both polyribosome fractionation and total transcriptome analysis. Samples were collected over three consecutive months. PARTICIPANTS/MATERIALS, SETTING, METHODS: All ICR mice were bred under legal permission for animal experimentation (no. MZE-24154/2021-18134) obtained from the Ministry of Agriculture of the Czech Republic. Actively translated (polyribosome occupied) maternal transcripts were detected in in vitro and in vivo matured mouse oocytes and zygotes by density gradient ultracentrifugation, followed by RNA isolation and high-throughput RNA sequencing. Bioinformatic analysis was performed and subsequent data validation was done by western blotting, radioactive isotope, and mitotracker dye labelling. MAIN RESULTS AND THE ROLE OF CHANCE: Gene expression analysis of acquired polysome-derived high-throughput RNA sequencing data revealed significant changes (RPKM ≥ 0.2; P ≤ 0.005) in translation between in vitro and in vivo matured oocytes and respectively produced pronuclear zygotes. Surprisingly, the comparison between IVM DO and IVM COC RNA-seq data of both fractionated and total transcriptome showed very few transcripts with more than a 2-fold difference. Data validation by radioactive isotope labelling revealed a decrease in global translation bof20% in IVM DO and COC samples in comparison to IVO samples. Moreover, IVM conditions compromised oocyte energy metabolism, which was demonstrated by both changes in polysome recruitment of each of 13 mt-protein-coding transcripts as well as by validation using mitotracker red staining. LARGE SCALE DATA: The data discussed in this publication have been deposited in NCBI's Gene Expression Omnibus and are accessible through GEO Series accession number GSE241633 (https://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE241633). LIMITATIONS, REASONS FOR CAUTION: It is extremely complicated to achieve in vivo consistency in animal model systems such as porcine or bovine. To achieve a high reproducibility of in vivo stimulations, the ICR mouse model was selected. However, careful interpretation of our findings with regard to assisted reproductive techniques has to be made by taking into consideration intra-species differences between the mouse model and humans. Also, the sole effect of the cumulus cells' contribution could not be adequately addressed by comparing IVM COC and IVM DO, because the IVM DO were matured without gonadotropin supplementation. WIDER IMPLICATIONS OF THE FINDINGS: Our findings confirmed the inferiority of standard IVM technology compared with the in vivo approach. It also pointed at compromised biological processes employed in the critical translational regulation of in vitro matured MII oocytes and pronuclear zygotes. By highlighting the importance of proper translational regulation during in vitro oocyte maturation, this study should prompt further clinical investigations in the context of translation.

Effects of pre/postnatal 2.45 GHz continuous wave (CW), Wireless-Fidelity (Wi-Fi) Microwave (MW) irradiation on bone have yet to be well defined. The present study used biochemical and histological methods to investigate effects on bone formation and resorption in the serum and the tibia bone tissues of growing rats exposed to MW irradiation during the pre/postnatal period. Six groups were created: one control group and five experimental groups subjected to low-level different electromagnetic fields (EMF) of growing male rats born from pregnant rats. During the experiment, the bodies of all five groups were exposed to 2.45 GHz CW-MW for one hour/day. EMF exposure started after fertilization in the experimental group. When the growing male rats were 45 days old in the postnatal period, the control and five experimental groups' growing male and maternal rats were sacrificed, and their tibia tissues were removed. Maternal rats were not included in the study. No differences were observed between the control and five experimental groups in Receptor Activator Nuclear factor-kB (RANK) biochemical results. In contrast, there was a statistically significant increase in soluble Receptor Activator of Nuclear factor-kB Ligand (sRANKL) and Osteoprotegerin (OPG) for 10 V/m and 15 V/m EMF values. Histologically, changes in the same groups supported biochemical results. These results indicate that pre/postnatal exposure to 2.45 GHz EMF at 10 and 15 V/m potentially affects bone development.

Deficit či obtížné dosahování ženského orgazmu je považováno v klasifikačních systémech pohlavních dysfunkcí za poruchu komplikující párovousexualitu. Tato premisa je běžně přijímána, přestože je koitální anorgazmie většinovou statistickou normou a dosažení orgazmu zevní stimulací není u žen tak snadné jako u mužů. Projevy ženského vyvrcholení jsou variabilní a souvisí s mnoha proměnlivými faktory. Některé teorie předpokládají vysokou míru korelace mezi schopností orgastického prožitku, sexuálními postoji a chováním, ale také souvislosti s reprodukčním potenciálem či stabilitou partnerských vztahů. Ženský orgazmus je mnohdy vnímán jako diskriminační mechanizmus determinující postoje k sexualitě nebo je dokonce považován za jakýsi katalyzátor plodnosti. Konsenzus o jeho významu neexistuje. Relevantní studie vyvracejí teorie o jeho pozitivních partnerských adaptačních funkcích i o vlivu na fertilitu. Orgazmus je u žen, pravděpodobně, vedlejším evolučním produktem jeho mužské varianty, neboť klitoris i penis mají identický embryonální základ. Ženská anorgazmie by neměla být považována za jednoznačnou diagnózu, natož za paradigma psychiatrického konstruktu působící frustrace či jiné problémy.

A deficit or problematic achievement of female orgasm is often classified as a sexual disorder that creates complications in the sex life of couples. This assumption is generally accepted, even though vaginal anorgasmia is an accepted statistical norm and non-coital methods of generating female orgasm are not as easy as they are for men. Female orgasms manifest themselves in different ways; they are variable and can be dependent on a number of variable factors. Some theories suggest a high degree of correlation between the capacity for orgasmic experience, sexual attitudes and behaviour, but also with reproductive potential or the stability of the given couple’s relationship. Female orgasm is often seen as a discriminatory mechanism influencing attitudes towards sexuality or even as a kind of fertility catalyst. There is no consensus on the importance of female orgasm. The results of some relevant studies refute theories about the female orgasm’s positive influence on adaptive functions of the couple’s relationship, as well as its influence on fertility. The orgasm in women is most likely an evolutionary by-product of its male variant, since the clitoris and penis have an identical embryonic basis of development. Female anorgasmia should not be considered an unquestioned diagnosis, let alone a psychiatric construct leading to a paradigm in which anorgasmia is categorically the cause of frustration or other problems.

Gender dysphoria (GD) is marked by an incongruence between a person's biological sex at birth, and their felt gender (or gender identity). There is continuing debate regarding the benefits and drawbacks of physiological treatment of GD in children, a pathway, beginning with endocrine treatment to suppress puberty. Currently, the main alternative to physiological treatment consists of the so-called "wait-and-see" approach, which often includes counseling or other psychotherapeutic treatment. In this paper, we argue in favor of a "third pathway" for the diagnosis and treatment of GD in youths. To make our case, we draw on a recent development in bioethics: the phenomenological approach. Scholars such as Slatman and Svenaeus have argued that the extent to which the body can (or should be) manipulated or reconstructed through medical intervention is not only determined by consideration of ethical frameworks and social and legal norms. Rather, we must also take account of patients' personal experience of their body, the personal and social values associated with it, and their understanding of its situation in their life: their narrative identities. We apply this phenomenological approach to medicine and nursing to the diagnosis and treatment of GD in youth. In particular, we discuss Zahavi and Martiny's conception of the phenomenological interview, in order to show that narrative techniques can assist in the process of gender identification and in the treatment of youth presenting with GD. We focus on two case studies that highlight the relevance of a narrative-based interview in relations between patients, HCPs, and family, to expose the influence of social ideologies on how young people presenting with GD experience their bodies and gender.

OBJECTIVE: Access to family planning services is a human right that plays an essential role in society's health, particularly women's health. The COVID-19 pandemic has affected all aspects of human life including access to family planning services. Accordingly, the main goal of this study was to explore the experiences of women and service providers from the main challenges and obstacles of access to family planning services and abortion services in Bangladesh, Iran, and the Netherlands during the COVID-19 pandemic. METHODS: In this qualitative study, the data were collected through online, telephone, or in-person semi-structured interviews with key informants. Participants selected by purposive sampling method. The participants included women aged 15 to 49 (n = 63) and service providers (n = 54) in the 3 abovementioned countries. These individuals were included from October 2020 until December 2020. Conventional thematic analysis was employed to analyze the collected data. RESULTS: The main extracted themes were challenges (reduction of referral; disruption of access to services; insufficient knowledge; worries among staff; rising prices; and unavailability of some contraceptives), measures (time extension and visit scheduling; telephone, online, and door to door services; and support of the media) and recommendations (health facility improvements; free, online, and closer services; and ongoing trainings and awareness campaigns). CONCLUSION: The COVID-19 pandemic has affected family planning and reproductive health services in different ways and has uncovered existing inequalities in access to these services. However, in Iran, the reported challenges were also rooted in new population policies that have further limited access to family planning and abortion services.

OBJECTIVE: To investigate the structural bases of human oocytes' cytoplasmic abnormalities and the causative mechanism of their emergence. Knowledge of an abnormal oocyte's intracellular organization is vital to establishing reliable criteria for clinical evaluation of oocyte morphology. DESIGN: Laboratory-based study on experimental material provided by a private assisted reproduction clinic. SETTING: University laboratory and imaging center. PATIENTS: A total of 105 women undergoing hormonal stimulation for in vitro fertilization (IVF) donated their spare oocytes for this study. INTERVENTIONS: Transmission electron microscopy (TEM) was used to analyze the fine morphology of 22 dysmorphic IVF oocytes exhibiting different types of cytoplasmic irregularities, namely, refractile bodies; centrally located cytoplasmic granularity (CLCG); smooth endoplasmic reticulum (SER) disc; and vacuoles. A total of 133 immature oocytes were exposed to cytoskeleton-targeting compounds or matured in control conditions, and their morphology was examined using fluorescent and electron microscopy. MAIN OUTCOME MEASURES: The ultrastructural morphology of dysmorphic oocytes was analyzed. Drug-treated oocytes had their maturation efficiency, chromosome-microtubule configurations, and fine intracellular morphology examined. RESULTS: TEM revealed ultrastructural characteristics of common oocyte aberrations and indicated that excessive organelle clustering was the underlying cause of 2 of the studied morphotypes. Inhibition experiments showed that disruption of actin, not microtubules, allows for inordinate aggregation of subcellular structures, resembling the ultrastructural pattern seen in morphologically abnormal oocytes retrieved in IVF cycles. These results imply that actin serves as a regulator of organelle distribution during human oocyte maturation. CONCLUSION: The ultrastructural analogy between dysmorphic oocytes and oocytes, in which actin network integrity was perturbed, suggests that dysfunction of the actin cytoskeleton might be implicated in generating common cytoplasmic aberrations. Knowledge of human oocytes' inner workings and the origin of morphological abnormalities is a step forward to a more objective oocyte quality assessment in IVF practice.

INTRODUCTION: The standard procedure in cervical cancer is radical hysterectomy and pelvic lymphadenectomy (PLND). Because of the increasing age of women bearing children, fertility has become a major challenge. We present pregnancy results after less radical fertility-sparing surgery in women with IA1, LVSI positive, IA2 and IB1 (<2 cm, infiltration less than half of the cervical stroma). MATERIALS AND METHOD: All women (n = 91) underwent laparoscopic sentinel lymph node mapping with frozen section followed by PLND and "selective parametrectomy" (removal of afferent lymphatic channels from the paracervix) if sentinel nodes (SLN) are negative. If lymph nodes were verified negative by definitive histopathology, patients were treated by simple trachelectomy (IB1) or large cone (IA1/IA2) biopsy 1 week after primary surgery. RESULTS: From 1999 to 2018, 91 women were enrolled in the study (median age 29.1 years, range 21-40). Fertility was spared in 76 (83.5%) women; 13 (17.1%) women did not plan future pregnancy and 63 (82.9%) had pregnancy desires. Fifty-four of 63 women conceived (pregnancy rate 85.7%) and 48 of 63 delivered 58 babies (delivery rate 76.2%). Thirty-nine women delivered in term (67.2%): 13 women between 32 and 36 + 6 weeks of pregnancy, 3 between 28 and 31 + 6 weeks and 3 between 24 and 27 + 6 weeks. Only one woman still plans pregnancy. One woman is currently pregnant. CONCLUSION: The goal of fertility-sparing surgery is to produce good oncological results and promising pregnancy outcomes. Pregnancy results after less radical fertility-sparing procedures show promise (pregnancy rate 82.9% and delivery rate 76.2%).

In 2018, the European Society of Gynecological Oncology (ESGO) jointly with the European Society for Radiotherapy and Oncology (ESTRO) and the European Society of Pathology (ESP) published evidence-based guidelines for the management of patients with cervical cancer. Given the large body of new evidence addressing the management of cervical cancer, the three sister societies jointly decided to update these evidence-based guidelines. The update includes new topics to provide comprehensive guidelines on all relevant issues of diagnosis and treatment in cervical cancer.To serve on the expert panel (27 experts across Europe) ESGO/ESTRO/ESP nominated practicing clinicians who are involved in managing patients with cervical cancer and have demonstrated leadership through their expertise in clinical care and research, national and international engagement, profile, and dedication to the topics addressed. To ensure the statements were evidence based, new data identified from a systematic search was reviewed and critically appraised. In the absence of any clear scientific evidence, judgment was based on the professional experience and consensus of the international development group. Before publication, the guidelines were reviewed by 155 independent international practitioners in cancer care delivery and patient representatives.These updated guidelines are comprehensive and cover staging, management, follow-up, long-term survivorship, quality of life and palliative care. Management includes fertility sparing treatment, early and locally advanced cervical cancer, invasive cervical cancer diagnosed on a simple hysterectomy specimen, cervical cancer in pregnancy, rare tumors, recurrent and metastatic diseases. The management algorithms and the principles of radiotherapy and pathological evaluation are also defined.
