You can get any gender of Nidoran by matching Nidoran (Male)/Nidorino/Nidoking with Ditto or Nidoran (Female) with Ditto or any male from the “Monster” or “Ground ”-Breed egg groups (Nidorina and Nidoqueen always failed to breed).
Nidoran♀ is an female only species.
Nidoking is a male species.
Female Nidoran can be found on Route 22 and the Safari Zone in Red and Blue but are easier to find in Blue. A Female Nidoran can also be traded for a Male Nidoran on Route 5 in Red and Blue.
Playing with Nidoqueen: “Almost always the better option“
Nidoqueen’s superior physique sets her apart from Nidoking, making her the only one of the two viable to choose anything other than purely offensive teams.
While Nidorina is incapable of breeding, Nidorino can breed with the shape-shifting Pokémon Ditto to lay eggs that will hatch either male or female Nidoran.
No, Nidoqueen is not a Legendary Pokémon.
Therefore you have to try Horde Battles or Friend Safari to get one with Sheer Force. If you then want to breed this to another Nidoran, note that now either the mother or the father can pass on her ability (previously it was only the mother). Note that the likelihood of disclosure is low.
When it comes to stats, the male Pokemon is slightly better than its female counterpart, so be sure to train Nidoran (M) first. The only downside to Nidoran is that it doesn’t learn any decent poisoning techniques on its own, so you might have to use TM 06 to pump up its poisonous side.

Best moveset for Nidoking
The best moves for Nidoking are Poison Jab and Earthquake when attacking Pokémon in Gyms. This move combo has the highest overall DPS and is also the best move set for PVP battles.
Nidoking excels as a powerful wallbreaker with sheer power and impressive coverage. A nice bonus is that it gets two stab moves, Earth Power and Sludge Wave, that benefit from Sheer Force, making them both excellent choices besides being two good offensive types.
To be compatible for breeding, the Pokémon must be in the same egg group. Two Pokémon in the Field Egg group will produce a Pokémon Egg, but if one Pokémon is in Field and the other is in Water 1, no Egg will be made.
