Comparison of spermiograms of men presenting due to infertility before and during the COVID-19 pandemic (preprint)

Background: Following the rapid global spread of the novel coronavirus SARS-CoV-2, the World Health Organization declared COVID-19 a pandemic on March 11, 2020. Over the intervening year, there has been interest in the impact of both SARS-CoV-2 infection and pandemic-induced social restrictions on male reproductive health. This study aimed to evaluate the spermiogram values of men who presented to a urology clinic due to infertility during the pandemic and compare the results with those in the previous two years. Materials and Methods: Patients who presented to the urology outpatient clinic of Medical Park Antalya Hospital Complex for the first time due to infertility were included. The patients’ age, semen volume, and spermiogram results were recorded. The patients were divided by presentation date into pre-pandemic group 1 (March 2018 - February 2019), pre-pandemic group 2 (March 2019 - February 2020), and the pandemic group (March 2020 - February 2021) for comparison. Results: A total of 594 patients were included in the study. There was no significant difference between the three groups in terms of the number of patients who presented (207, 190, and 197 patients, respectively; p=0.691). The mean age was 36.6±7.2 in pre-pandemic group 1, 35.5±7.1 in pre-pandemic group 2, and 33.1±6.3 in the pandemic group. Patients who presented during the pandemic were significantly younger (p<0.001). There was no difference in semen volume among the groups (p=0.910). Analysis of spermiogram results revealed no significant differences in normospermia and pathological spermiogram rates by year (p=0.222). Conclusion : In the first year of the COVID-19 pandemic, there was no significant difference in the number of men who presented for infertility or in their spermiogram results compared to 2018 and 2019. However, it is noteworthy that the patients were significantly younger during the pandemic than in the previous two years.

Social Media Use: Awareness of Covid-19 Vaccine and Acceptance among Undergraduate Students in Kano State, Nigeria (preprint)

Background: The outbreak of Covid-19 of 2019 and its escalation to a global pandemic posed threat to public health worldwide. Although availability and acceptance of Covid-19 vaccination is a crucial step to cushioning the pandemic, hesitancy tends to hamper the success of the vaccination. Whereas social media platforms are potential tools for information dissemination, particularly to the millennial generation, governments scarcely exploit the sites to create awareness of Covid-19 vaccine, hence, the room for the spread of unverified information that can affect their public health decisions. This study, therefore, examines the relationships between social media use, awareness of Covid-19 vaccine, and hesitancy or acceptance among undergraduate Universities in Kano. Three Universities were selected (Bayero University Kano, Northwest Universities, and Skyline University Nigeria).Method: A cross-sectional online survey was adopted, a structured questionnaire was created on google forms and the link generated thereof was distributed to the undergraduates via Whatsapp and Facebook platforms. Descriptive and inferential analyses were conducted using SPSS and the results were presented in text, figures, and tables.Results: The study shows a strong significant correlation between social use and awareness of Covid-19 vaccine at a P = 0.001 level. However, it shows no significant correlation between awareness of Covid-19 vaccine and acceptance of the vaccination at a P = 0.006. The result also shows a statistical relationship between vaccine hesitancy and fear of infertility, no relationship was established between vaccine hesitancy and religious belief, mistrust of the vaccine source, and vaccine safety concerns. Those spending much time on social media receive Covid-19 vaccine the most. Similarly, those relying on social media as their major source of information about Covid-19 have more tendencies of accepting the vaccine.Conclusions: A crosstabulation hour spent on social media and receiving Covid-19 vaccine indicates that those spending 5 and above hours on social media are the highest receivers of Covid-19 jab. Thus, spending many hours on social media is inversely proportional to receiving the vaccine.

The Relationship between Treatment Suspension Due to the Coronavirus Pandemic and Mental Health of Infertile Patients: A Systematic Review andMeta-Analysis (preprint)

Background Access to fertility treatments is considered a reproductive right, but because of the quarantine due to the coronavirus pandemic most infertility treatments were suspended, which might affect the psychological and emotional health of infertile patients. Therefore, this study was conducted to review the relationship between treatment suspension due to the coronavirus pandemic and the mental health of infertile patients.Methods This study was conducted based on the Meta-analysis Of Observational Studies in Epidemiology (MOOSE) guideline. The ISI, PubMed, Embase, Scopus, and Cochrane library databases were searched by two independent researchers, without time limitation until 31 December 2022. All observational studies regarding the mental health of infertile patients facing treatment suspension including anxiety, depression, and stress were included in the study. Qualitative studies, editorials, brief communications, commentaries, conference papers, guidelines, and studies with no full text were excluded. Quality assessment was carried out using Newcastle-Ottawa Scale by two researchers, independently. The random effects model was used to estimate the pooled prevalence of mental health problems. Meta-regression and subgroup analysis were used to confirm the sources of heterogeneity.Results Out of 681 studies, 21 studies with 5901 patients including 5306 female and 504 male infertile patients were systematically reviewed, from which 16 studies were included in the meta-analysis. The results of all pooled studies showed that the prevalence of anxiety, depression, and stress in female patients was 48.4% (95% CI 34.8–62.3), 42% (95% CI 26.7–59.4), and 55% (95% CI 45.4–65), respectively. Additionally, 64.4% (95% CI 50.7–76.1) of patients wished to resume their treatments despite the coronavirus pandemic.Conclusion Treatment suspension due to the coronavirus pandemic negatively affected the mental health of infertile patients. It is important to maintain the continuity of fertility care, with special attention paid to mental health of infertile patients, through all the possible measures even during a public health crisis.

Inactivated COVID-19 Vaccination did not affect In vitro fertilization (IVF) / Intra-Cytoplasmic Sperm Injection (ICSI) cycle outcomes (preprint)

Background: The objective of this study is to evaluate the impact of COVID-19 inactivated vaccine administration on the outcomes of in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) cycles in infertile couples in China. Methods: We collected data from the CYART prospective cohort, which included couples undergoing IVF treatment from January 2021 to September 2022 at Sichuan Jinxin Xinan Women & Children's Hospital. Based on whether they received vaccination before ovarian stimulation, the couples were divided into the vaccination group and the non-vaccination group. We compared the laboratory parameters and pregnancy outcomes between the two groups. Findings: After performing propensity score matching (PSM), the analysis demonstrated similar clinical pregnancy rates, biochemical pregnancy and ongoing pregnancy rates between vaccinated and unvaccinated women. No significant disparities were found in terms of embryo development and laboratory parameters among the groups. Moreover, male vaccination had no impact on patient performance or pregnancy outcomes in assisted reproductive technology treatments. Additionally, there were no significant differences observed in the effects of vaccination on embryo development and pregnancy outcomes among couples undergoing ART. Interpretation: The findings suggest that COVID-19 vaccination did not have a significant effect on patients undergoing IVF/ICSI with fresh embryo transfer. Therefore, it is recommended that couples should receive COVID-19 vaccination as scheduled to help mitigate the COVID-19 pandemic.

The prevalence of adjustment disorder and predisposing factors in infertile women.

BACKGROUND: Infertility is a stressful life event that increases the risk of developing mental disorders, particularly adjustment disorder (AD). Given the paucity of data on the prevalence of AD symptoms in infertility, the purpose of this study was to ascertain the prevalence, clinical presentation, and risk factors for AD symptoms in infertile women. METHOD: In a cross-sectional study, 386 infertile women completed questionnaires including the Adjustment Disorder New Module-20 (ADNM), the Fertility Problem Inventory (FPI), the Coronavirus Anxiety Scale (CAS), and the Primary Care Posttraumatic Stress Disorder (PC-PTSD-5) at an infertility center between September 2020 and January 2022. RESULT: The results indicated that 60.1% of infertile women exhibited AD symptoms (based on ADNM > 47.5). In terms of clinical presentation, impulsive behavior was more common. No significant relationship was observed between prevalence and women's age or duration of infertility. Infertility stress (ß = 0.27, p < 0.001), coronavirus anxiety (ß = 0.59, p = 0.13), and a history of unsuccessful assisted reproductive therapies (ß = 2.72, p = 0.008) were several predisposing factors for AD symptoms in infertile women. CONCLUSIONS: The findings suggest that all infertile women be screened from the start of infertility treatment. Additionally, the study suggests that infertility specialists should focus on combining medical and psychological treatments for individuals predisposed to AD, particularly infertile women who exhibit impulsive behaviors.

The value of motherhood and psychological distress among infertile women: The mediating role of coping strategies.

Introduction: The present study investigated psychological distress and coping strategies among infertile women during the COVID-19 pandemic using a multi-dimensional model of infertility-related stress. We explored the associations between individual (i.e., age) and situational characteristics related to infertility (i.e., duration of infertility, cause of infertility, number of lost pregnancies, and assisted reproductive techniques [ART] status), and perceived-infertility-related factors (i.e., the perceived importance of motherhood). Methods: Our total sample consisted of 193 women aged 20 to 46 (M= 33.23, SD = 4.58), out of which 102 were undergoing ART procedures (M = 33.60, SD = 4.23), and 91 were not (M= 32.81, SD = 4.94). Participants filled in questionnaires measuring psychological distress, coping strategies, and the importance of motherhood. Results: Correlation analyses suggested that the importance of motherhood was positively associated with psychological distress and negative coping strategies. Mediation analysis results indicated that both in the overall sample and in the sample of women undergoing ART procedures, the negative self-perception fully mediated the link between the importance of motherhood on psychological distress. In the non-ART sample, we found a significant mediation effect of denial on the link between the importance of motherhood and psychological distress. Discussion: We discuss the theoretical and practical implications of the present findings, focusing on the mental health-related consequences of the social stigma of infertility heightened by the pressure of parenthood.

CoronaVac vaccine does not affect ovarian reserve.

OBJECTIVES: In this study, our aim is to investigate the effect of CoronaVac vaccine on ovarian reserve in female patients followed up for infertility. MATERIAL AND METHODS: Our study is a retrospective study. Forty-six infertile patients who received two doses of CoronaVac vaccine one month apart and had not had a previous Covid 19 infection were included in the study. Anti-müllerian hormone (AMH) and folliculometry of 46 patients one month before CoronaVac vaccine and one month after the second dose of vaccine were compared. RESULTS: There was no statistically significant difference in the change of AMH level and follicle number before and after vaccination (respectively p = 0.366; 0.610). CONCLUSIONS: Considering that having a COVID-19 infection has a negative effect on female fertility and causing ovarian damage in recent studies, vaccination is a rational and cost-effective approach to protect ovarian reserve. Knowing that the vaccine does not have a negative effect on fertility may increase the application of the vaccine in women of reproductive age.

Sociodemographic inequity in COVID-19 vaccine uptake among youth in Zimbabwe (preprint)

Introduction COVID-19 vaccine acceptance research has mostly originated from high-income countries and reasons why youth may not get vaccinated may differ in low-income settings. Understanding vaccination coverage across different population groups and the sociocultural influences in healthcare delivery is important to inform targeted vaccination campaigns. Methods A population-based survey was conducted in 24 communities across three provinces (Harare, Bulawayo and Mashonaland East) in Zimbabwe between October 2021 and June 2022. Youth aged 18 - 24 years were recruited using random sampling. Data on sociodemographic information and COVID-19 vaccination uptake and reasons for non-uptake were collected. Results A total of 17,682 youth were recruited (n=10,743, 60.8% female). The median age of survey participants was 20 (IQR: 19-22) years. Almost two thirds (n=10,651, 60.2%) of participants reported receiving at least one dose of COVID-19 vaccine. A higher proportion of men than women had been vaccinated (68.9% vs 54.7%), and vaccination prevalence increased with age (<19 years: 57.5%, 20-22: 61.5%, >23: 62.2%). Lack of time to get vaccinated, belief that the vaccine was unsafe and anxiety about side effects (particularly infertility) were the main reasons for not getting vaccinated. Factors associated with vaccination were male sex (OR=1.69, 95%CI:1.58-1.80), increasing age (>22 years: OR=1.12, 95%CI:1.04-1.21), education level (post-secondary: OR=4.34, 95%CI:3.27-5.76), and socioeconomic status (least poor: OR=1.32, 95%CI:1.20-1.47). Conclusion This study found vaccine inequity across age, sex, educational attainment and socioeconomic status among youth. Strategies should address these inequities by understanding concerns and tailoring vaccine campaigns to specific groups.

Depression and Anxiety in Infertility Patients (preprint)

Depression and anxiety are common emotional responses among infertility patients, with research showing that they can negatively impact the mental well-being and quality of life of individuals struggling with infertility. This study aimed to conduct a bibliometric analysis of the existing literature on depression and anxiety in infertility patients, in order to shed light on the current state of research and identify potential areas for future study. The majority of research on depression and anxiety in infertility patients has been conducted in recent years, with a growing interest in the topic. Numerous investigations have assessed the effect of infertility treatments on patients’ psychological health, with some examinations delving into the application of cognitive behavioral therapy and mindfulness-based stress reduction as potential methods for mitigating symptoms of depression and anxiety. Polycystic ovary syndrome, fertility preservation of cancer patients, COVID-19 pandemic, and assisted reproductive technology are also hot spots in this field. The findings of this bibliometric analysis highlight the importance of addressing depression and anxiety in infertility patients, and imply that further investigation is required to fully comprehend the intricate connections between infertility, depression, and anxiety.

Individualized medicine using 3D printing technology in gynecology: a scoping review (preprint)

Objective: Developments in 3-dimensional (3D) printing technology has made it possible to produce high quality, affordable 3D printed models for use in medicine. As a result, there is a growing assessment of this approach being published in the medical literature. The objective of this study was to outline the clinical applications of individualized 3D printing in gynecology through a scoping review. Data Sources: Four medical databases (Medline, Embase, Cochrane CENTRAL, Scopus) and grey literature were searched for publications meeting eligibility criteria up to 31 May 2021. Study Eligibility Criteria: Publications were included if they were published in English, had a gynecologic context, and involved production of patient specific 3D printed product(s). Study Appraisal and Synthesis Methods: Studies were manually screened and assessed for eligibility by two independent reviewers and data were extracted using pre-established criteria using Covidence software. Results: Overall, 32 studies (15 abstracts,17 full text articles) were included in the scoping review. Most studies were either case reports (12/32,38%) or case series (15/32,47%). Gynecologic sub-specialties in which the 3D printed models were intended for use included: gynecologic oncology (21/32,66%), benign gynecology (6/32,19%), pediatrics (2/32,6%), urogynecology (2/32,6%) and reproductive endocrinology and infertility (1/32,3%). Twenty studies (63%) printed 5 or less models, 6/32 (19%) printed greater than 5 (up to 50 models). Types of 3D models printed included: anatomical models (11/32,34%), medical devices, (2/32,6%) and template/guide/cylindrical applicators for brachytherapy (19/32,59%). Conclusions: Our scoping review has outlined novel clinical applications for individualized 3D printed models in gynecology. To date, they have mainly been used for production of patient specific 3D printed brachytherapy guides/applicators in patients with gynecologic cancer. However, individualized 3D printing shows great promise for utility in surgical planning, surgical education, and production of patient specific devices, across gynecologic subspecialties. Evidence supporting the clinical value of individualized 3D printing in gynecology is limited by studies with small sample size and non-standardized reporting, which should be the focus of future studies.

Meeting Report: Third International Congress of the International Society of Uterus Transplantation, Tübingen.

Uterus transplantation (UTx) is currently the only available treatment for absolute uterine factor infertility. The International Society of Uterus Transplantation (ISUTx) was formally founded in 2017 and joined the Transplantation Society as a formal section in 2021. The Third International Congress of the ISUTx was held in Tübingen, Germany, in October 2021, as a hybrid meeting, attended virtually by about 450 delegates and in person by 35 delegates. This report summarizes the Tübingen meeting and complementary topics of relevance presented at the Second ISUTx state-of-the-art webinar meeting, held in Prague, in October 2020. Main topics covered included surgical considerations, including dissection of veins in living donors and the pros and cons of minimally invasive surgery; managing immune risks; UTx during the COVID-19 pandemic; lessons learnt in the areas of imaging and cytomegalovirus infection; long-term psychological outcomes; opportunities to increase organ availability; and new horizons in UTx, including potential reuse of transplants and the utilization of robotic approaches. Implementation of an International UTx Registry was discussed and considered crucial to assure quality, safety, and further progress in UTx. Attempts made thus far have been promising.

Impact of COVID-19 pandemic on depression and hopelessness in infertile women.

INTRODUCTION: COVID-19 has negative and sometimes irreversible effects on infertile women. This study aimed to investigate hopelessness and depression in infertile women whose treatment has been delayed due to COVID-19. METHODS: This case-control study was conducted online on 172 infertile women. The case group included infertile women under treatment whose treatment was delayed during the COVID-19 pandemic, and the control group was selected from infertile women who were not under infertile treatment. This study was conducted between April and December 2021 in Jahrom, Iran. Beck hopelessness standard questionnaire (BHS) and Beck Depression Inventory (BDI) were used to collect data, and p < 0.05 was considered significant. RESULTS: The mean score of hopelessness in women in the case group was 9.48 ± 1.80 compared to the control group 8.66 ± 1.34 (OR = 1.39 95% CI = 1.13-1.71), and its areas (OR = 1.33 95% CI = 1.003-2.43), Emotions and expectations score (OR = 1.59 95% CI = 1.07-2.37), Motivation loss score (OR = 2.02 95% CI = 1.49-2.73), Hope score, and depression in women in the case group was 40.33 ± 10.87to 36.72 ± 11.40 compared to the control (OR = 1.17 95% CI = 1.11-1.23). All these variables showed an increase in the case group compared to the control group (p < 0.05). CONCLUSION: The results showed that infertile women whose treatment was delayed were more frustrated and depressed than women in the control group. COVID-19 epidemic and discontinuation of infertile treatments in infertile women seem to have negative psychological effects. Therefore, the psychological effects of this epidemic on infertile women should not be ignored, so planners should put social and family support at the top of the program.

The First 5 Years of Uterus Transplant in the US: A Report From the United States Uterus Transplant Consortium.

Importance: Uterus transplant is a viable surgical treatment for women affected by absolute uterine-factor infertility, which affects 1 in 500 women. Objective: To review transplant and birth outcomes of uterus transplant recipients in the US since the first case in 2016. Design, Setting, and Participants: In this cohort study, 5 years of uterus transplant outcome data were collected from the 3 centers performing uterus transplants in the US: Baylor University Medical Center, Dallas, Texas; Cleveland Clinic, Cleveland, Ohio; and University of Pennsylvania, Philadelphia. A total of 33 women with absolute uterine-factor infertility who underwent uterus transplant between February 2016 and September 2021 were included. Main Outcomes and Measures: Graft survival, live birth, and neonatal outcome. Results: Of the 33 included uterus transplant recipients, 2 (6%) were Asian, 1 (3%) was Black, 1 (3%) was South Asian, and 29 (88%) were White; the mean (SD) age was 31 (4.7) years; and the mean (SD) body mass index (calculated as weight in kilograms divided by height in meters squared) was 24 (3.6). Most uterus transplant recipients (31 of 33 [94%]) had a congenitally absent uterus (Mayer-Rokitansky-Küster-Hauser syndrome), and 21 of 33 (64%) received organs from living donors. Mean (range) follow-up was 36 (1-67) months. There was no donor or recipient mortality. One-year graft survival was 74% (23 of 31 recipients). Through October 2021, 19 of 33 recipients (58%) had delivered 21 live-born children. Among recipients with a viable graft at 1 year, the proportion with a live-born child was 83% (19 of 23). The median (range) gestational age at birth of neonates was 36 weeks 6 days (30 weeks, 1 day to 38 weeks), and the median (range) birth weight was 2860 (1310-3940) g (median [range], 58th [6th-98th] percentile). No congenital malformations were detected. Conclusions and Relevance: Uterus transplant is a surgical therapy that enables women with uterine-factor infertility to successfully gestate and deliver children. Aggregate data from US centers demonstrate safety for the recipient, living donor, and child. These data may be used to counsel women with uterine-factor infertility on treatment options.

Usage of mobile health interventions among overweight/obese PCOS patients undergoing assisted reproductive technology treatment during the COVID-19 pandemic.

Objective: In the context of the coronavirus disease 2019 (COVID-19) pandemic, telemedicine is a promising tool for providing clinical care for patients. Since the first-line treatment for infertile women with polycystic ovarian syndrome (PCOS) is lifestyle modification, a mobile-based service that provides lifestyle modification education would be helpful in the treatment of PCOS patients. In this observational study, the effect of a mobile Health (mHealth) application for lifestyle modification on PCOS patients undergoing assisted reproductive technology (ART) treatment was evaluated.Methods: A total of 79 overweight/obese patients (40 in the paper group and 39 in the WeChat application group) with PCOS from the First Affiliated Hospital of University of Science and Technology of China were enrolled in the study. The changes in the outcomes of BMI and ART treatment were analyzed between the two groups.Results: After three months of intervention, the BMIs in the control and mHealth groups were 24.5 ± 3.3 and 23.7 ± 3.1, respectively. The percentage of patients who lost weight was higher in the WeChat group than in the control group (87.2% vs. 67.5%). Furthermore, PCOS patients in the WeChat group were found to have a higher live birth rate than those in the control group (p = 0.005).Conclusion: Lifestyle modifications for PCOS patients undergoing ART treatment using the WeChat application improved weight loss and oocyte quality. Infertile patients with PCOS were more likely to make lifestyle modifications based on the usage of mobile applications during the COVID-19 pandemic.

The effect of SARS-CoV-2 mRNA vaccination on AMH concentrations in infertile women.

RESEARCH QUESTION: Does SARS-CoV-2 mRNA vaccination affect the ovarian reserve of infertile women undergoing IVF? DESIGN: This was a prospective observational study at a single university-affiliated IVF unit that included infertile women aged 18-44 years who were undergoing IVF/intracytoplasmic sperm injection between November 2020 and September 2021, had received two doses of SARS-CoV-2 mRNA vaccination and had undergone measurement of baseline anti-Müllerian hormone (AMH) concentration within the 12 months preceding their recruitment. AMH concentrations before and after vaccination were evaluated and compared. RESULTS: Overall, 31 women were included in the study. The median AMH concentrations before and after COVID-19 vaccine were comparable (1.7 versus 1.6 g/ml, respectively, P = 0.96). No correlation was found between the participant's anti-COVID-19 antibody titre and the change in AMH concentration. CONCLUSIONS: SARS-CoV-2 mRNA vaccination does not adversely affect ovarian reserve, as shown by comparing serum AMH concentrations before and after vaccination. These findings may serve as a counselling tool for clinicians to reassure women undergoing fertility treatment that SARS-CoV-2 mRNA vaccination is safe.

Maternal and neonatal outcomes of pregnancies of infertile women during the COVID-19 pandemic: a real world evidence.

OBJECTIVE: The COVID-19 pandemic began in Dec. 2019 and its effects on pregnancy outcomes are still unknown. This study aimed to evaluate the pregnancy outcomes of infertile women who conceived during the COVID-19 pandemic. METHODS: This cross-sectional study included infertile women who conceived during the COVID-19 pandemic. Infertile women referred to the infertility center at the Vali-e-Asr hospital who conceived spontaneously or with the aid of ART (IUI, ICSI) were included and followed until delivery or pregnancy termination. RESULTS: A total of 38 pregnant women (34 conceiving after ART and four spontaneously) were included. Seventeen (44.74%) of the 38 pregnant women developed COVID-19 symptoms. No significant difference was detected in maternal and neonatal outcomes, including miscarriage, PROM, low birth weight, or premature birth between pregnancies with and without COVID-19 symptoms. A significant difference was found between the two groups in delivery route. CONCLUSIONS: No associations were found with maternal and neonatal morbidity in women conceiving during the COVID-19 pandemic and in pregnant women with and without COVID-19 symptoms.

Preliminary Results for Personalized Therapy in Pregnant Women with Polycystic Ovary Syndrome During the COVID-19 Pandemic.

Increased androgen level, hyperinsulinemia, diabetes, impaired fibrinolysis, obesity, hypertension, chronic inflammation, abnormal immune response to infections and hyperhomocysteinemia are the most common abnormalities related to polycystic ovary syndrome (PCOS) women and are the factors predisposing to the severe course of COVID-19. The SARS-Cov-2 infection during pregnancy is associated with an increased risk of complications (spontaneous abortion), similar to those in PCOS. The treatment of PCOS pregnant women with a history of fertility failures raises many doubts, especially during the COVID pandemic. However, due to the increasing incidence of infections among reproductive people and the potentially more serious course in pregnant women, numerous questions about the safety and effectiveness of the treatment are still very current. In our study we presented a series of cases of recurrent miscarriages or recurrent implantation failure PCOS pregnant women with confirmed COVID-19. The diagnosis of infertility confirmed the presence of plasminogen activator inhibitor type 1 and/or 5,10-methylenetetrahydrofolate reductase polymorphisms in each of them. Moreover, some of the women presented immune dysfunction associated with infertility. We have described the personalized treatments of each pregnant patient included: metformin, enoxaparin and tacrolimus. The treatment applied had the expected effect, supporting the implantation processes. Furthermore, despite the ambiguous data according to immunological therapy of infertile women during the COVID pandemic, we observed a mild or asymptomatic COVID-19 course and we noticed no pregnancy complications.

No evidence of fetal defects or anti-syncytin-1 antibody induction following COVID-19 mRNA vaccination (preprint)

The impact of coronavirus disease 2019 (COVID-19) mRNA vaccination on pregnancy and fertility has become a major topic of public interest. We investigated two of the most widely propagated claims to determine 1) whether COVID-19 mRNA vaccination of mice during early pregnancy is associated with an increased incidence of birth defects or growth abnormalities, and 2) whether COVID-19 mRNA-vaccinated human volunteers exhibit elevated levels of antibodies to the human placental protein syncytin-1. Using a mouse model, we found that intramuscular COVID-19 mRNA vaccination during early pregnancy at gestational age E7.5 did not lead to differences in fetal size by crown-rump length or weight at term, nor did we observe any gross birth defects. In contrast, injection of the TLR3 agonist and double-stranded RNA mimic polyinosinic-polycytidylic acid, or poly(I:C), impacted growth in utero leading to reduced fetal size. No overt maternal illness following either vaccination or poly(I:C) exposure was observed. We also found that term fetuses from vaccinated murine pregnancies exhibit high circulating levels of anti-Spike and anti-RBD antibodies to SARS-CoV-2 consistent with maternal antibody status, indicating transplacental transfer. Finally, we did not detect increased levels of circulating anti-syncytin-1 antibodies in a cohort of COVID-19 vaccinated adults compared to unvaccinated adults by ELISA. Our findings contradict popular claims associating COVID-19 mRNA vaccination with infertility and adverse neonatal outcomes.

Understanding the cross-talk between mediators of infertility and COVID-19.

COVID-19 is the ongoing health emergency affecting individuals of all ages around the globe. Initially, the infection was reported to affect pulmonary structures. However, recent studies have delineated the impacts of COVID-19 on the reproductive system of both men and women. Hence, the present review aims to shed light on the distribution of SARS-CoV-2 entry factors in various reproductive organs. In addition, impacts of COVID-19 mediators like disrupted renin angiotensin system, oxidative stress, cytokine storm, fever, and the mental stress on reproductive physiology have also been discussed. For the present study, various keywords were used to search literature on PubMed, ScienceDirect, and Google Scholar databases. Articles were screened for relevancy and were studied in detail for qualitative synthesis of the review. Through our literature review, we found a multitude of effects of COVID-19 mediators on reproductive systems. Studies reported expression of receptors like ACE-2, TMPRSS2, and CD147 in the testes, epididymis, prostrate, seminal vesicles, and ovarian follicles. These proteins are known to serve as major SARS-CoV-2 entry factors. The expression of lysosomal cathepsins (CTSB/CTSL) and/ neuropilin-1 (NRP-1) are also evident in the testes, epididymis, seminal vesicles, fallopian tube, cervix, and endometrium. The binding of viral spike protein with ACE-2 was found to alter the renin-angiotensin cascade, which could invite additional infertility problems. Furthermore, COVID-19 mediated cytokine storm, oxidative stress, and elevated body temperature could be detrimental to gametogenesis, steroidogenesis, and reproductive cycles in patients. Finally, social isolation, confinement, and job insecurities have fueled mental stress and frustration that might promote glucocorticoid-mediated subnormal sperm quality in men and higher risk of miscarriage in women. Hence, the influence of COVID-19 on the alteration of reproductive health and fertility is quite apparent.
