The Apple II came out in 1977.
The Super Serial Card is dated 1981.
The IBM PC came out in 1982.

Further, there has always been a design bias toward making connectors
that are installed on a box be female, to make it less likely that they
would be damaged (bent pins) and require a difficult replacement.

I suspect the IBM PC designers would have followed the same convention
except that they reused the DB-25 for both the serial and the parallel
ports, making a gender shift in one desirable from a human engineering
point of view.

One could argue that they should have decided to make the parallel port
male, since female serial connectors (on boxes) were widespread by the
time the PC was designed.
