You can basically assume the overall population gender ratio was 1:1, the birth ratio might have been different but that is expected.
It's a self correcting phenomenon where the ratio self selects towards 1:1.

i.e. did you know that genetic analyses have revealed that ancestrally, only 40% of men managed to reproduce, while 80% of women did? Maybe more relevant to what we're actually discussing.
I'm not sure how fast exactly human birth ratios swing but I would hazard a guess a few dozen generations would be enough to self select at least partially back towards the norm. How long did it take the worlds population to recover after WW1/2?
I'm happy to see evidence contrary but please don't just dismiss things as if evolution is working on geological timescales it's just not.
