Do you have any source that on " (one I've seen a lot is that 'women may become temporarily infertile'), despite every trial not showing any such side-effects."

Do you have any source that on " (one I've seen a lot is that 'women may become temporarily infertile'), despite every trial not showing any such side-effects.". I want to forward it to the ppl I know who heard this. To show this, they need to monitor the conception rate after vaccination with the control group. Is this actually monitored? (what I sometimes found that 'no evidence' means 'we do not have data';like they claim in German trains no transmission has ever been found; spoiler, they didnt register and check names of passengers)
