You are getting onto dangerous ground here in two ways. Firstly, you seem to be forgetting that you are posting on a site where pregnant women or the relatives of pregnant women may well be viewing. Pregnancy is potentially stressful at the best of times. You might want to stop and think about that before making claims like yours without any evidence.
The second way in which you are moving onto dangerous ground is that your claims can be easily checked. If vaccinated men produce spike protein instead of sperm (I’ve never heard that one before!) and there is a wave of miscarriages in the vaccinated, I think we can agree that there would be evidence of a collapse of birth rates after the roll out.
