We can see that men aren't as careful about physical distancing, this is obvious at supermarkets, right? Women also have stronger immune system, but in men, the cytokine reactions are excessive and often fatal. Men tend to socialize more, smoke and drink more than women, although no one is an angel. And unfortunately, men have higher concentration of ACE2, the protein that sars cov 2 binds upon.
The topic of discussion that you have raised sounds very interesting and thank you for that. But is there any proven evidence for this? Is it being observed in selected places or is it the world picture?
This phenomenon (higher mortality from COVID-19 in men) is not yet fully understood. However, many factors can be involved. Some of them are: hormones, different immune responses in men and women, sex-related differences in the distribution/prevalence of major cardiovascular risk factors and comorbidities, ...

The difference is, above all, in the social behavior of men and women. A woman is more careful about her health, she is more executive. This plays a big role. In principle, it is difficult to say whether female or male physiology is affected or not. But today men get sick more than women. Perhaps this is due to social behavior. There is also a scientific explanation.
There are studies that have confirmed the presence of ACE2 receptors (through which the virus enters the body) in the tissues of the male reproductive organs, in the tissues of the testicles.
Dear Moez Ltifi thank you for this interesting and very important technical question. In fact, it seems now well-established that the death rate for men from COVID-19 is higher than for women. For more recent information about the possible reasons please see the following useful links:
1. Coronavirus (COVID-19) and the different effects on men and women in the UK, March 2020 to February 2021
Usually all men have higher exposure to the Covid 19, and do interactions with others higher then female. So it is understood that the death rat will also be high as compare to females.
Direct exposure to the virus, and we have the fact that women are much more careful, moreover even in the vital system it is the mother who protects everything!
Transcription of transmembrane protease serine 2 (TMPRSS2) is largely accused, alongside angiotensin-converting enzyme 2 (ACE2), of helping the coronavirus enter the target cells, and regulation of TMPRSS2 is mediated by androgen receptor.
This makes males more vulnerable to a stronger infection and more likely to die.

Females have higher numbers of CD4+ T cells, more robust CD8+ T cell cytotoxic activity, and increased B cell production of immunoglobulin compared to males.
It could be linked to some sex-based differences we're seeing in men and women in the context of COVID-19, such as sex chromosome-linked genes, sex hormones, and the microbiome, which all control aspects of immune responses to infection and are potentially important biological contributors to the sex-based differences we're seeing in men and women.
Men have higher concentrations of angiotensin-converting enzyme 2 (ACE2) in their blood than women. SARS-CoV-2, the virus that causes COVID-19 uses ACE2 to gain cellular entry.
According to the following article, the causes are explained in terms of activity of the immune system and its modulation by sex hormones, coagulation pattern, and preexisting cardiovascular diseases as well as effects deriving from smoking and drinking habits.
