In wizarding world, omega is the one who can get pregnant, regardless the chromosome XX or XY. Hence, an infertile omega is something considered as broken.
Graves ever since he has presented as an omega, has problem with fertility. His heats are infrequent and irregular. It all work well for him who wished to pursue career as an Auror. A mishap in prejudiced and bigoted coworker during his early days as an auror had further worsened his fertility problem.
Hence he experience very little to no heats. He is regarded as a broken one. No alpha or beta courts him. No one wished to build relationship with him outside being his colleagues or coworkers.
During his captive, Grindelwald messed his biology even more. So after the rescue, Graves is leaking both slick and pheromone to entice mating but because of his infertility, it leaves sour and unpleasant smell. Alphas and betas steer clear of him. So during his time in mediwizard wing, no one come close. He is alone in his suffering. These false heats cannot be cured or healed. Mediwizard can only alleviate the symptoms with potions and suggest to let the false heats run their course. The other way to this condition is a bonding of the said omega with an alpha so the bond will stabilize the heats.
Graves, of course, prepared to endure the false heats alone. He knows who he is and what he is. So he resigned to his fate.
Enter Newt and Credence who are both alphas.
Bonus: <3 If Graves resisted the idea of bonding at first because he is old and barren. What good of an omega for both young and virile alphas. <3 <3 If both Newt and Credence have to court him first <3 <3 <3 That actually Newt and Credence do not know about this matter until is already past few months because they decided to run outta America as soon as Grindelwald's capture but before Graves is found. <3 <3 <3 <3 Both Newt and Credence knots on Graves. <3 <3 <3 <3 <3 virgin!Graves! After all what's the use to have sex with an infertile omega?
