I've asked 5 different AI to help me with this and they all had errors. The maximum number of rounds we can play is 7. You get a new partner each round. Let's say we have 4 women/8 men (12) OR 6 women and 10 men (16), I would like the last match of each round to be men vs men.
12 players:
2 mixed matches
1 men match
16 players:
3 mixed matches
1 men match
Following this format would be perfect as I was able to use it with Python codes:
(H1 W4 v H2 W7)
(H3 W1 v H4 W5)
(H5 W3 v H6 W8 )
(H7 W6 v H8 W2)
(H1 W7 v H3 W6)
(H2 W5 v H7 W3)
(H4 W2 v H5 W8 )
(H6 W1 v H8 W4)
(H1 W6 v H4 W8 )
H2 W4 v H8 W5)
(H3 W7 v H5 W2)
(H6 W3 v H7 W1)
(H1 W3 v H5 W4)
(H2 W8 v H6 W7)
(H3 W5 v H8 W6)
(H4 W1 v H7 W2)
(H1 W5 v H6 W2)
(H2 W1 v H3 W8 )
(H4 W3 v H8 W7)
(H5 W6 v H7 W4)
(H1 W8 v H7 W5)
(H2 W3 v H4 W6)
(H3 W2 v H6 W4)
(H5 W7 v H8 W1)
(H1 W2 v H8 W3)
(H2 W6 v H5 W1)
(H3 W4 v H7 W8 )
(H4 W7 v H6 W5)

I can say on the basis of theory that no 'nice' schedule will be possible for your 12 player scenario, I don't have any software that can try to make such a schedule, but I am sure the balance would be very poor. However, I can offer something for 16 players (6 women and 10 men) and 5 rounds - this can work well with every player being scheduled to play with every other player exactly once. I have labelled the female players F1 to F6 and the male players M1 to M9 plus MX for the tenth man.
Court 1 Mixed Court 2 Mixed Court 3 Mixed Court 4 Men Only
(M4 F1 v M6 F2) (MX F6 v M9 F3) (M7 F4 v M8 F5) (M1 M2 v M3 M5)
(M9 F5 v M5 F2) (M4 F4 v M2 F3) (M1 F1 v M7 F6) (M6 M3 v M8 MX)
(M8 F6 v M2 F2) (M9 F1 v M3 F4) (M6 F3 v M1 F5) (M5 M7 v M4 MX)
(MX F1 v M2 F5) (M5 F6 v M6 F4) (M3 F3 v M7 F2) (M4 M8 v M9 M1)
(M1 F2 v MX F4) (M3 F5 v M4 F6) (M5 F1 v M8 F3) (M2 M6 v M7 M9)
Each woman has 5 rounds of mixed doubles, playing with all ten men exactly once (5 as partners and 5 as opponents), and opposes each other woman exactly once.
Each man has 3 rounds of mixed doubles, playing with all 6 women (3 as partners and 3 as opponents), and has 2 rounds of mens doubles.
Hope that is of some help.

Amazing. This looks like a lot of work. I will definitely use the draw. Thank you so much.

Ian, would there be an easy way to add two more rounds? It would be OK to play against the same opponent as long as players don't have the same partner.
