Abstract Numerous studies have revealed severe damage to male fertility from acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) infection, raising concerns about the potential adverse impact on reproductive function of disease 2019 (COVID‐19) vaccine developed based virus. Interestingly, there are several researchers who studied COVID‐19 mRNA since then but come up with conflicting results. As a near‐ideal candidate for mass immunization programs, inactivated SARS‐CoV‐2 has been widely used in many countries, particularly less wealthy nations. However, little is known its effect fertility. Here, we conducted retrospective cohort study at single large center medicine China between December 2021 and August 2022. Five hundred nineteen fertile men no history laboratory‐confirmed were included categorized into four groups their vaccination status: unvaccinated group ( n = 168), one‐dose vaccinated 8), fully 183), booster 160). All them underwent semen analysis most had serum sex hormone levels tested. There significant differences all parameters either group. To account possible vaccination‐to‐test interval‐specific changes, sub‐analyses performed two interval groups: ≤90 >90 days. expected, remained unchanged control groups. participants (≤90 days) decreased total sperm motility increased follicle‐stimulating level compared ones Moreover, some trends similar those found during infection recovery observed our study. Fortunately, values within normal range. In addition, reported few reactions. No special medical intervention was required, serious reactions happened. Our suggests that does not impair fertility, possibly due low frequency effects. This information reassures young population got this worldwide, helps guide future efforts.

Some reproductive-aged individuals remain unvaccinated against coronavirus disease 2019 (COVID-19) because of concerns about potential adverse effects on fertility. Using data from an internet-based preconception cohort study, we examined the associations COVID-19 vaccination and severe acute respiratory syndrome 2 (SARS-CoV-2) infection with fertility among couples trying to conceive spontaneously. We enrolled 2,126 self-identified female participants aged 21-45 year residing in United States or Canada during December 2020-September 2021 followed them through November 2021. Participants completed questionnaires every 8 weeks sociodemographics, lifestyle, medical factors, partner information. fit proportional probabilities regression models estimate between self-reported SARS-CoV-2 both partners fecundability (i.e., per-cycle probability conception), adjusting for confounders. was not appreciably associated either (female ratio (FR) = 1.08, 95% confidence interval (CI): 0.95, 1.23; male FR CI: 0.83, 1.10).

Introduction Several vaccines against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have been developed since the inception of disease 2019 (COVID-19) in December 2019, at unprecedented speed. However, these rapidly raised many questions related to efficacy and safety different communities across globe. Various hypotheses regarding COVID-19 its were generated, them also answered with scientific evidence. Still, there are myths/misinformation vaccines, which create hesitancy for vaccination, must be addressed critically achieve success battle pandemic.Area Covered The development anti-SARS-CoV-2 COVID-19, their efficacy, relating presented.Expert Opinion In this pandemic, we seen a global collaborative effort researchers, governments, industry, supported by billions dollars funding, allowed far more quickly than past. Vaccines go through rigorous testing, analysis, evaluations clinical settings prior approval, even if they approved emergency use.

Currently, death rate has reduced due decreased pathogenicity new SARS-CoV-2 variants, but major factor in rates is administration 12.8 billion vaccine doses globally. While vaccines are saving lives, serious side effects after vaccinations for several premature non-communicable diseases (NCDs). However, adverse events low number. The scientific community must investigate entire spectrum COVID-19-vaccine-induced complications so that necessary safety measures can be taken, current re-engineered avoid or minimize their effects.
