Among the multitude of statistics and dramatic numbers that the coronavirus is leaving around the world, there is a fact that many have begun to realize these weeks: COVID-19 would be killing more men than women.

Despite the fact that the statistics of many countries are lacking in many details, the medical community worldwide has managed to detect that this virus is being more lethal with them than with them.

Already in early February, the Chinese Center for Disease Control and Prevention (CCDC) conducted the first patient study. With a sample of 138 patients, which later increased to 72,314, they concluded that the mortality rate was higher in men: 2.8% in men compared to 1.7% in women, as reported by the BBC.

Subsequently, another study published in the British medical journal Lancet on data from patients infected with the virus revealed that men accounted for more than 60% of infections and that the average age of both sexes was 55 years.

But staying with the lethality by sex, Sabra Klein, from the department of molecular microbiology and immunology at the John Hopkins University School of Public Health, explained to the BBC that estrogens, the main group of female sex hormones, could have become an important factor in this pandemic.

“Estrogens can stimulate aspects of immunity that are important for eliminating a viral infection and responding well to vaccines,” he explained.

Other experts point to a number of other factors, such as men having more chronic diseases than women, making them more vulnerable. In general, if we talk about ages of risk, men are more likely to smoke than women, and smoking encourages the virus to stick to the pulmonary alveoli, so it is more normal for them to have previous pathologies that are very sensitive to COVID-19, such as hypertension, cardiovascular and cerebrovascular disease, COPD and diabetes.
