Abstract
PURPOSE This study aims to better understand the knowledge and attitudes of men and women internationally towards oocyte cryopreservation (OC). METHODS An online 25-question survey was distributed internationally via email and social media. Knowledge and attitudes towards OC among different regions and genders were assessed. The study population consisted of adults from North America (NA, 15.7%), Southeastern and Eastern Europe (SE, 34.7%), Central and Western Europe (CWE, 12.7%), Asia (12.7%), and Middle East (ME, 8.9%). RESULTS A total of 496 respondents initiated the survey and the completion rate was 80.2%. The mean (SD) age was 35.2 (12.1) years. Over 70% were aware of OC, but only 4.8% had previously undergone the procedure. Most considered ages 26-31 as optimal for OC and correctly identified conditions that could impact the chance of spontaneous conception. Significant differences were observed regarding etiologies that would render OC acceptable. Only in NA and ME did solid majorities strongly agree that it is acceptable to proceed with OC to allow more time to find the right partner or for professional opportunities. More similar opinions were observed between genders. When medical conditions existed, large majorities across all nationalities and genders strongly agreed that OC is acceptable. In NA, SE, and ME most respondents would consider or recommend OC for any reason, whereas most respondents in CWE and Asia would do that only for certain social reasons or medical necessity. CONCLUSION A good understanding of OC was observed. Nationality appeared to impact opinions on appropriate indications for this procedure, though overall positive attitudes were documented.

Abstract
Although oocyte cryopreservation was initially used as a fertility preservation strategy for medical indications, it is now is increasingly used to circumvent age-related infertility. Outcomes following planned oocyte vitrification, also known as elective egg freezing, are limited. Current studies show higher success rates for individuals undergoing fertility preservation treatment under age 35. Additionally, while freezing 20 oocytes is optimal to achieve pregnancy, freezing at least 8-10 oocytes is recommended. While fertility is not guaranteed, current evidence demonstrates that planned oocyte vitrification is an overall safe, low risk method of fertility preservation to reduce the risk for age-related infertility.

The first nationwide website survey of the availability and costs of medical and non-medical oocyte cryopreservation in Japan. Heliyon 2023; 9:e19074. [PMID: 37636403 PMCID: PMC10448461 DOI: 10.1016/j.heliyon.2023.e19074] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2022] [Revised: 08/02/2023] [Accepted: 08/10/2023] [Indexed: 08/29/2023] Open
Abstract
Research question How does the cost-related oocyte cryopreservation (OoC) vary by the facility in Japan, and what data is provided on the websites about OoC procedures? Design Website survey. The websites of all 621 facilities that provide assistive reproductive technology registered in Japan were surveyed in 2021. Data included the rates of explicit statements regarding the provision of OoC for only medical reasons (medical only group) or non-medical reasons (non-medical group). Based on whether or not facilities that perform OoC clearly stated the cost on their websites, we compared the costs of OoC and annual storage cost between medical only and non-medical groups. Furthermore, we examined the stated number of OoC procedures performed and their clinical outcomes. Results Of the 621 facilities, 146 (23.5%) clearly stated that they offer OoC on their websites. Of the 88 medical only groups and 58 non-medical groups, 24 (27.3%) and 42 (72.4%) clearly stated the OoC cost, and 27 (30.7%) and 44 (75.9%) clearly states the annual oocyte storage cost, respectively. The OoC costs were significantly higher for the non-medical group than in the medical group. In the medical only group, the annual storage cost remained almost the same regardless of the number of oocytes, while in the non-medical group, the annual storage cost was 2-3 times higher than in the medical only group. Only 16 facilities (16/146, 11.0%) had mentioned the number of OoC procedures, and five facilities (3.4%) provided information on the clinical outcomes after OoC. Conclusion Costs related to OoC are higher for the non-medical group in Japan. In addition, the websites contain scant information on the costs and clinical outcomes of OoC.

Sciorio R, Manna C, Fauque P, Rinaudo P. Can Cryopreservation in Assisted Reproductive Technology (ART) Induce Epigenetic Changes to Gametes and Embryos? J Clin Med 2023; 12:4444. [PMID: 37445479 DOI: 10.3390/jcm12134444] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2023] [Revised: 06/05/2023] [Accepted: 06/29/2023] [Indexed: 07/15/2023] Open
Abstract
Since the birth of Louise Brown in 1978, more than nine million children have been conceived using assisted reproductive technologies (ARTs). While the great majority of children are healthy, there are concerns about the potential epigenetic consequences of gametes and embryo manipulation. In fact, during the preimplantation period, major waves of epigenetic reprogramming occur. Epigenetic reprogramming is susceptible to environmental changes induced by ovarian stimulation, in-vitro fertilization, and embryo culture, as well as cryopreservation procedures. This review summarizes the evidence relating to oocytes and embryo cryopreservation and potential epigenetic regulation. Overall, it appears that the stress induced by vitrification, including osmotic shock, temperature and pH changes, and toxicity of cryoprotectants, might induce epigenetic and transcriptomic changes in oocytes and embryos. It is currently unclear if these changes will have potential consequences for the health of future offspring.

Abstract
BACKGROUND Knowledge about fertility and factors affecting it, for example, the impact of age, seem to be lacking, even in highly educated populations. The same applies to fertility preservation knowledge, pointing to the relevance of increasing fertility preservation awareness and education among young women. OBJECTIVE To describe general fertility knowledge and factors affecting fertility, fertility preservation knowledge and attitudes, and the desire to access more information on this topic in a sample of reproductive-age Portuguese women. METHODS The sample comprised 257 Portuguese women aged 18-45, mostly single and nulliparous. A questionnaire was developed explicitly for this study and disseminated through social media advertisements. RESULTS Career building/development and financial stability were the more endorsed options for delaying childbearing, with 90 (35%) and 68 (26.5%), respectively. Most participants considered becoming a mother important (n = 185; 72%). More than halve provided an incorrect answer regarding the age range of women being more fertile (n = 132; 51.4%) and the age range of fertility decline (n = 168; 65.4%). Participants were aware of the influence of lifestyle and sexual health factors as well as the effect of age. Oocytes cryopreservation was the technique participants knew more (n = 206; 80.1%), but 177 (68.9%) showed no interest in using it. Most participants agreed that fertility and fertility preservation information should be provided during medical consultations or at school. CONCLUSIONS More information regarding fertility and fertility preservation is relevant to ensure that more women can make informed decisions concerning their reproductive life.

Abstract
Fertility is often a concern for women with SLE. In addition to known indirect factors that influence the ability of a woman with SLE to become pregnant, such as cytotoxic agents, other medications, advanced age and psychosocial effects of the disease, direct disease-related factors are believed to influence fertility. These include diminished ovarian reserve, menstrual irregularities (a function of disease activity) and the presence of antiphospholipid antibodies. The question of whether SLE intrinsically affects fertility, however, remains unanswered. In this review, we address known factors affecting fertility, assess current data regarding a direct impact of SLE on fertility and evaluate potential disease-related risk factors. We focus primarily on studies measuring anti-Müllerian hormone and antral follicle count, the most widely measured markers of ovarian reserve. Our goal is to provide information to rheumatologists faced with counselling patients with SLE regarding their fertility, family planning and options for assisted reproductive technologies, which now include fertility preservation through oocyte cryopreservation.

Abstract
Oocyte vitrification is an important assisted reproductive technology (ART) that preserves the fertility of unmarried patients with malignant tumors, and promotes the development of the oocyte donation program. In recent years, the effects of ART, including the vitrification of oocytes and embryos on the health of offspring, have attracted much attention; however, it is difficult to conduct long-term follow-up and biochemical evaluation in humans. In this study, we detected the effect of oocyte vitrification on gene expression in the organs of adult mice offspring by RNA sequencing for the first time. Our results showed that only a small amount of gene expression was significantly affected. Seven genes (Tpm3, Hspe1-rs1, Ntrk2, Cyp4a31, Asic5, Cyp4a14, Retsat) were abnormally expressed in the liver, and ten genes (Lbp, Hspe1-rs1, Prxl2b, Pfn3, Gm9008, Bglap3, Col8a1, Hmgcr, Ero1lb, Ifi44l) were abnormal in the kidney. Several genes were related to metabolism and disease occurrence in the liver or kidney. Besides, we paid special attention to the expression of known imprinted genes and DNA methylation-related genes in adult organs, which are susceptible to oocyte cryopreservation in the preimplantation stage. As a result, some of these transcripts were detected in adult organs, but they were not affected by oocyte vitrification. In conclusion, we first report that oocyte vitrification did not significantly change the global gene expression in offspring organs; nonetheless, it can still influence the transcription of a few functional genes. The potential adverse effects caused by oocyte vitrification need attention and further study.

Abstract
PURPOSE To determine whether exposure to digital educational content affects fertility awareness and attitudes towards fertility preservation treatments? METHODS A total of 957 women ages 20 to 45 years participated in this internet-based, interventional, cross-sectional study. A questionnaire assessing knowledge of the reproductive span and attitudes towards fertility preservation treatment was completed by these women before and after exposure to online educational content on ovarian reserve and fertility preservation treatments. Responses before and after exposure to the educational content were compared. RESULTS Knowledge about female age-related fertility decline improved significantly after exposure to educational content (51.6% vs. 79.6%, p < 0.001). Increased willingness to pursue fertility preservation treatments (38.6% vs. 42.9%, p < 0.001) and to recommend fertility preservation treatments to friends (55% vs. 65.2%, p < 0.001) was observed. Participants who desired to conceive were more positively influenced by the exposure to educational content in their attitudes towards fertility treatments compared to those who do not desire to conceive. CONCLUSIONS Online educational content has the potential to improve fertility awareness and shape a more positive attitude towards fertility preservation treatments for the public.

J Assist Reprod Genet 2022; 39:1997-2014.

Abstract
Purpose Vitrification permits long-term banking of oocytes and embryos. It is a technically challenging procedure requiring direct handling and movement of cells between potentially cytotoxic cryoprotectant solutions. Variation in adherence to timing, and ability to trace cells during the procedure, affects survival post-warming. We hypothesized that minimizing direct handling will simplify the procedure and improve traceability. To address this, we present a novel photopolymerized device that houses the sample during vitrification. Methods The fabricated device consisted of two components: the Pod and Garage. Single mouse oocytes or embryos were housed in a Pod, with multiple Pods docked into a Garage. The suitability of the device for cryogenic application was assessed by repeated vitrification and warming cycles. Oocytes or early blastocyst-stage embryos were vitrified either using standard practice or within Pods and a Garage and compared to non-vitrified control groups. Post-warming, we assessed survival rate, oocyte developmental potential (fertilization and subsequent development) and metabolism (autofluorescence). Results Vitrification within the device occurred within ~ 3 nL of cryoprotectant: this volume being ~ 1000-fold lower than standard vitrification. Compared to standard practice, vitrification and warming within our device showed no differences in viability, developmental competency, or metabolism for oocytes and embryos. The device housed the sample during processing, which improved traceability and minimized handling. Interestingly, vitrification-warming itself, altered oocyte and embryo metabolism. Conclusion The Pod and Garage system minimized the volume of cryoprotectant at vitrification—by ~ 1000-fold—improved traceability and reduced direct handling of the sample. This is a major step in simplifying the procedure.
