Context: Whilst radioactive iodine (RAI) is often administered in the treatment for differentiated thyroid carcinoma (DTC), long-term data on male fertility after RAI are scarce. Objective: To evaluate long-term male fertility after RAI for DTC, and to compare semen quality before and after RAI. Design, Setting, and Patients: Multicenter study including males with DTC ≥2 years after their final RAI treatment with a cumulative activity of ≥3.7 GBq. Main Outcome Measure(s): Semen analysis, hormonal evaluation, and a fertility-focused questionnaire. Cut-off scores for ‘low semen quality’ were based on reference values of the general population as defined by the World Health Organization. Results: Fifty-one participants had a median age of 40.5 (interquartile range, IQR, 34.0-49.6) years upon evaluation, and a median follow-up of 5.8 (IQR 3.0-9.5) years after their last RAI administration. The median cumulative administered activity of RAI was 7.4 (range 3.7-23.3) GBq. The proportion of males with a low semen volume, concentration, progressive motility, or total motile sperm count (TMSC) did not differ from the 10th percentile cut-off of a general population (P=0.500, P=0.131, P=0.094, and P=0.500, respectively). Cryopreserved semen was used by one participant of the twenty who had preserved semen. Conclusions: Participants had a normal long-term semen quality. The proportion of participants with low semen quality parameters scoring below the 10th percentile did not differ from the general population. Cryopreservation of semen of males with DTC is not crucial for conceiving a child after RAI administration, but may be considered in individual cases.

Background. Radioactive iodine (RAI) ablation is recommended for most patients with differentiated thyroid carcinoma (DTC) after total thyroidectomy (TT). We aimed to compare long-term outcomes between intermediate-dose (100 mCi) and high-dose (150 mCi) RAI ablation therapy in patients with DTC using propensity score matching analysis. Methods. This was a retrospective study of 1448 patients with DTC who underwent RAI ablation after TT. Propensity score matching was performed using the extent of operation, tumor size, extrathyroidal extension, multifocality, lymphatic invasion, vascular invasion, perineural invasion, number of positive lymph nodes (LNs), ATA risk stratification system, T stage, N stage, TNM stage, preoperative serum Tg and TgAb levels, and post-RAI serum Tg and TgAb levels. Results. Recurrence rates in the intermediate- and high-dose groups were 3.1% and 5.6%, respectively. After propensity score matching, LN ratio >0.22 (HR, 2.915; 95% CI, 1.228–6.918; p = 0.015 ) and serum Tg >10 ng/mL after RAI (HR, 3.976; 95% CI, 1.839–8.595; p < 0.001 ) were significant predictors of recurrence. Kaplan–Meier analysis showed no significant difference in DFS before or after propensity score matching ( p = 0.074 and p = 0.378 , respectively). Conclusions. Intermediate-dose RAI ablation for the adjuvant treatment of DTC is sufficient as compared to high-dose RAI ablation. Further prospective or multicenter studies should be conducted to clarify the prognosis of intermediate-dose RAI ablation.

AbstractIt is estimated that in Central and Eastern Europe 8–12% of men are infertile, and in the case of 20% of infertile couples in the region, indicates a 56% part of the malefactor in the occurrence of infertility. Numerous studies have shown that a healthy diet with a high intake of fish and seafood, poultry, vegetables, fruits, legumes, through the high content of antioxidants are associated with better parameters of semen quality and reduced risk of asthenozoospermia. Men's diets may affect spermatogenesis as reflected in semen quality indicators, but the literature on the relation between meat intake and semen quality is limited. Our objective was to prospectively examine the relation between meats including red, poultry, proceesed and fish and indicators of semen quality. Men in subfertile couples presenting for evaluation at the Olsztyn Hospital Fertility Center were invited to participate in an ongoing study of environmental factors and fertility. This cross-sectional study was carried out in 208 men aged 18–55 years from Northern-Eastern Poland. Semen samples were collected at the clinic and analyses were performed by an experienced technician. Semen microscopic measurements were determined with the use of computer-aided semen analysis (CASA) and evaluated according to the World Health Organization (WHO) guidelines. A total of men completed a validated food-frequency questionnaire and subsequently provided semen samples. We used linear mixed regression models to examine the relation between meat intake and semen quality indicators (total sperm count, sperm concentration, progressive motility, morphology, and semen volume) while adjusting for potential confounders. After adjustment for age, BMI, physical activity, residence place and education, one serving increase in intake of processed meat was associated with a 56% higher risk of abnormal progressive sperm motility (OR = 1.56 95%CI:1.09–2.21). Consuming processed meat may have a negative impact on sperm counts and morphology. Potentially, these products may be a significant source of saturated and trans fatty acids, xenobiotics, mainly xenoestrogen, and steroids. Is need to clarify the potential effect of meat products, especially processed meat, on male reproductive potential in RCTs or longitudinal studies. Future findings may be useful to establish a more precise recommendation connected with red and processed meat intake in the context of reproductive health.

Lay summary Firefighters are occupationally exposed to heat intensities and chemical concentrations that may affect fertility. Twenty firefighters participated in an exploratory study assessing fertility of firefighters via an online survey and semen analysis. Data analysis included consideration of demographic characteristics, reproductive history and occupational exposures. Overall, firefighter semen parameters were below World Health Organisation reference values designating fertility in men. Firefighters younger than 45 years had a higher incidence of abnormal semen parameters (42%) than those aged 45 years or greater (9%). Increased rank and higher levels of occupational and/or personal hygiene were associated with improved semen quality. Increased frequency of fire exposure was associated with a reduction in normal forms, volume, sperm concentration and total sperm count. Sperm clumping was greater than 10% in 26% of samples, suggesting reduced semen quality. This exploratory study provides novel data that support the hypothesis of an association between semen quality and firefighter’s occupational exposure to toxic environments.

OBJECTIVE: To assess differences in semen quality between similar populations from Denmark and Finland. DESIGN: Comparison of semen quality between 221 Finnish men (of whom 115 had no proven fertility) and 411 Danish men with no proven fertility in two follow-up studies among normal couples trying to conceive. METHODS: In Finland male partners of couples without experienced infertility attempting to conceive were recruited through advertisements in local newspapers from 1984 to 1986. From 1992 to 1995 Danish men who lived with a partner and who had not attempted to achieve a pregnancy previously were recruited through their union when they discontinued birth control. All semen analyses were performed in accordance with the World Health Organization guidelines. RESULTS: Median sperm concentration, total sperm count and the percentage of morphologically normal spermatozoa were significantly higher among the Finnish men without proven fertility (104.0 million/ml, 304.0 million and 58% respectively) compared with the Danish men (53.0 million/ml, 140.8 million, and 41% respectively). Sperm concentration was 105.7% (95% confidence interval (CI) 58.1%-167.6%) and total sperm count was 127.4% (95% CI 71.4%-201.6%) higher among Finnish men without proven fertility than among Danish men after control for confounders. CONCLUSIONS: Some, but hardly all, of the observed difference in semen quality may be explained by differences in recruitment procedures, selection of the men and by methodological differences in semen analysis between the two countries. Also a birth cohort effect may explain some of the differences between countries as the Finnish men were recruited 11 years before the Danish men. Therefore, follow-up studies with identical recruitment and selection of men from the two countries are needed.

Background: LenshookeTM Semen Quality Analyzer (SQA) X1 Pro is an automated semen analysis. The accuracy of LenshookeTM SQA X1 Pro has never been analyzed with World Health Organization (WHO) standard method. Aim: This study aims to examine whether the LenshookeTM SQA X1 Pro method provides reliable results according to the WHO standard method. Methods: This study was a laboratory analytic observational study using 60 patients in Andrology clinic of Dr. Soetomo Hospital. The concentration, progressive motility (PR), total motile sperm count (TMSC), and morphology results of the LenshookeTM SQA X1 Pro and standard method were analyzed statistically using correlation, Bland Altman, and diagnostic test. Results: Significant correlation between two methods were found in all parameters (concentration: r = 0,970; PR: r = 0,781; TMSC: r = 0,952; morphology: r = 0,568). The mean difference for concentration, PR, TMSC, and morphology between the two examination methods were 1,165 million/ml, 7,05%, 7,584 million/ejaculate, and 2,25%. However, it found that the correlation and agreement were weaker in sample with low number of spermatozoa per high power field. The results revealed a sensitivity of 100%, 81%, and 59% for oligozoospermia, astenozoospermia, and teratozoospermia, respectively. The specificities were shown to be 100%, 74%, and 100% for oligozoospermia, astenozoospermia, and teratozoospermia, respectively. Conclusion: The LenshookeTM SQA X1 Pro gives a reliable result for determining oligozoospermia and asthenozoospermia, but in the situation that the clinicians need the accurate data, standard method should be used.

Abstract Background Follicular thyroid carcinoma is the second most common malignancy of the thyroid gland. In 2016, the so-called Hurthle cell thyroid carcinoma, formerly known as the oxyphilic variant of the follicular thyroid carcinoma, was reclassified by the World Health Organization as a separate pathological entity, which accounts for approximately 3% of all thyroid cancers. Although Hurthle cell thyroid carcinomas are known for their more aggressive tumor biology, metastases are observed in a minority of cases, and long-term survival can be expected. However, disseminated disease is often associated with poor outcome. Case presentation In the presented case, a 63-year-old Caucasian female was incidentally diagnosed with Hurthle cell thyroid carcinoma after undergoing hemithyroidectomy for a nodular goiter. Following completion thyroidectomy, two courses of radioactive iodine therapy were administered. After 4 years of uneventful follow-up, the patient gradually developed metastases in five different organs, with the majority representing unusual sites, such as heart, kidney, and pancreas over a course of 14 years. The lesions were either treated with radioactive iodine therapy or removed surgically, depending on iodine avidity. Conclusion Follicular and Hurthle cell thyroid carcinoma are known to potentially spread hematogenously to typical sites, such as lung or bones, however; unusual metastatic sites as presented in our case can also be observed. A search of the literature revealed only scattered reports on patients with multiple metastases in unusual locations. Furthermore, the observed long-term survival of our patient is contradictory to the existing data. As demonstrated, recurrent disease may appear years after the initial diagnosis, emphasizing the importance of consistent aftercare. Radioactive iodine therapy, extracorporeal radiation therapy, and surgical metastasectomy are central therapeutic components. In summary, our case exemplifies that thorough aftercare and aggressive treatment enables long-term survival even in recurrent Hurthle cell thyroid carcinoma displaying unusual multisite metastases.

Bisphenol A (BPA) is considered an endocrine disruptor and has been associated with deleterious effects on spermatogenesis and male fertility. Bisphenol F (BPF) and S (BPS) are structurally similar to BPA, but knowledge of their effects on male fertility remains limited. In this cross–sectional study, we investigated the associations between exposure to BPA, BPF, and BPS and semen quality in 556 men 18–20 years of age from the Fetal Programming of Semen Quality (FEPOS) cohort. A urine sample was collected from each participant for determination of BPA, BPF, and BPS concentrations while a semen sample was collected to determine ejaculate volume, sperm concentration, total sperm count, sperm motility, and sperm morphology. Associations between urinary bisphenol levels (continuous and quartile–divided) and semen characteristics were estimated using a negative binomial regression model adjusting for urine creatinine concentration, alcohol intake, smoking status, body mass index (BMI), fever, sexual abstinence time, maternal pre–pregnancy BMI, and first trimester smoking, and highest parental education during first trimester. We found no associations between urinary bisphenol of semen quality in a sample of young men from the general Danish population.

AbstractObjectivesThe aims were to analyze the clinical features, response to treatment, prognostic factors and long-term follow-up of children and adolescents with differentiated thyroid carcinoma (DTC).MethodsEighty patients with DTC were studied retrospectively. All underwent total or near-total thyroidectomy, and in 75 cases, ablative iodine therapy was recommended. Patients were assessed periodically by tests for serum thyroglobulin levels and whole-body iodine scans. Age, gender, initial clinical presentation, histology, tumor stage, postoperative complications, radioiodine treatment protocol, treatment response, thyroglobulin (Tg), recurrence and long-term disease progression were evaluated.ResultsSeventy patients completed >2 years of follow-up (23 males, 47 females; median age: 14 years; range: 3–18 years). Sixty-two patients showed papillary DTC and eight, follicular DTC. Sixty-five percent presented nodal metastasis and 16%, pulmonary metastasis at diagnosis. Six months after first radioiodine treatment, 36.2% of patients were free of disease. Seven recurrences were documented. At the end of follow-up, overall survival was 100%, and 87.2% of patients were in complete remission. Nine patients had persistent disease. We found a significant association between stage 4 and persistent disease. Hundred percent of patients with negative Tg values at 6 months posttreatment were documented free of disease at the end of the follow-up. The analysis of disease-free survival based on radioiodine treatment protocols used showed no statistically significant differences.ConclusionsDTC in children and adolescents is frequently associated with presence of advanced disease at diagnosis. Despite this, complete remission was documented after treatment in most cases, with a good prognosis in the long-term follow-up. Negative posttreatment thyroglobulin and stage 4 at diagnosis were significant prognostic variables.
