Evaluation of sex-related hormones and semen characteristics in reproductive-aged male COVID-19 patients.

ABSTRACT: In the past several months, the outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-associated infection (coronavirus disease 2019 [COVID-19]) developed rapidly and has turned into a global pandemic. Although SARS-CoV-2 mainly attacks respiratory systems, manifestations of multiple organs have been observed. A great concern was raised about whether COVID-19 may affect male reproductive functions. In this study, we collected semen specimens from 12 male COVID-19 patients for virus detection and semen characteristics analysis. No SARS-CoV-2 was found in semen specimens. Eight out of 12 patients had normal semen quality. We also compared the sex-related hormone levels between 119 reproductive-aged men with SARS-CoV-2 infection and 273 age-matched control men. A higher serum luteinizing hormone (LH) and a lower ratio of testosterone (T) to LH were observed in the COVID-19 group. Multiple regression analysis indicated that serum T: LH ratio was negatively associated with white blood cell counts and C-reactive protein levels in COVID-19 patients. It's the first report about semen assessment and sex-hormone evaluation in reproductive-aged male COVID-19 patients. Although further study is needed to clarify the reasons and underlying mechanisms, our study presents an abnormal sex hormone secretion among COVID-19 patients, suggesting that attention should be paid to reproductive function evaluation in the follow-up.

Project description:BackgroundFew human studies have examined bisphenol A (BPA) exposure in relation to semen quality and reproductive hormones in men, and results are divergent.ObjectivesWe examined associations between urinary BPA concentration and reproductive hormones, as well as semen quality, in young men from the general population.MethodsOur study population consisted of 308 young men from the general population. Urinary BPA concentration was measured by isotope dilution TurboFlow-liquid chromatography-tandem mass spectrometry. We used multiple linear regression analysis to estimate associations between BPA concentration and reproductive hormones and semen quality, adjusting for confounding factors.ResultsWe found that 98% of the men had detectable urinary levels of BPA. Median (5th-95th percentiles) BPA concentration was 3.25 ng/mL (0.59-14.89 ng/mL). Men with BPA concentrations above the lowest quartile had higher concentrations of serum testosterone, luteinizing hormone (LH), estradiol, and free testosterone compared with the lowest quartile (p trend ? 0.02). Men in the highest quartile of BPA excretion had on average 18% higher total testosterone (95% CI: 8, 28%), 22% higher LH (95% CI: 6, 39%), and 13% higher estradiol (95% CI: 4, 24%) compared with lowest quartile. Men in the highest quartile of BPA also had significantly lower percentage progressive motile spermatozoa compared with men in the lowest quartile (-6.7 percentage points, 95% CI: -11.76, -1.63). BPA was not associated with other semen parameters. Adjusting for dietary patterns did not influence the results.ConclusionsThe pattern of associations between BPA and reproductive hormones could indicate an antiandrogenic or antiestrogenic effect, or both, of BPA on the hypothalamic-pituitary-gonadal hormone feedback system, possibly through a competitive inhibition at the receptor level. However, additional research is needed to confirm our findings and to further test the suggested potential mechanisms.

Project description:STUDY QUESTION:Is adherence to an a priori defined diet quality indices [Alternate Healthy Index 2010 (AHEI-2010), relative Mediterranean diet score (rMED) or dietary approaches to stop hypertension (DASH)] associated with semen quality and reproductive hormone levels in young men? SUMMARY ANSWER:Greater adherence to the DASH diet is related to higher sperm counts. WHAT IS KNOWN ALREADY:Studies assessing the relationship between dietary intake and male reproductive function have mainly been focused on specific nutrients, food groups or data-driven dietary patterns, but the evidence on a priori defined dietary indices is still scarce. STUDY DESIGN, SIZE, DURATION:Cross-sectional study of 209 male university students recruited from October 2010 to November 2011 in Murcia Region (Southern Spain). PARTICIPANTS/MATERIALS, SETTING, METHODS:Healthy young men aged 18-23 years were included in this study. Diet was assessed using a validated food frequency questionnaire and three a priori-defined dietary indices (AHEI-2010, rMED and DASH) were calculated. Linear regression was used to analyze the relation between the three dietary indices and semen quality parameters and reproductive hormone levels accounting for potential confounders and covariates. MAIN RESULTS AND THE ROLE OF CHANCE:We found statistically significant positive associations between the DASH index and sperm concentration (P, trend?=?0.04), total sperm count (P, trend?=?0.04) and total motile sperm count (P, trend?=?0.02). No associations were observed for other semen parameters or male reproductive hormones. LIMITATIONS, REASONS FOR CAUTION:Even though we adjusted for several known and suspected confounders we cannot exclude the possibility of residual or unmeasured confounding or chance findings. Subjects were blinded to the study outcomes thus reducing the potential influence on their report of diet. Our sample size may be too small to rule out associations with other semen parameters or reproductive hormones. Causal inference is limited, as usual with all observational studies. WIDER IMPLICATIONS OF THE FINDINGS:The results suggest that greater adherence to the DASH may help improve sperm counts. This study was carried out on young men from the general population. However, results may differ among other populations (e.g. infertile men). Therefore, further research is needed to confirm these findings and extend these results to other populations.
