Gender

Gender is a concept introduced in Generation II, though touched upon in Generation I. In Gold and Silver Versions, most species were assigned a gender (male or female), and then, in Pokémon Crystal, a choice of male or female player characters became available for the first time. This feature allowed for Pokémon breeding, as well as introducing the concept of a Pokémon Egg to the series. Gender makes no difference in the stats of a Pokémon after Generation II, unless the two Pokémon are a different species entirely, such as Nidoran.

Gender differences

Main article: List of Pokémon with gender differences

Generation IV premiered minimal differences in sprite between two Pokémon of the same species. For example, a male Raichu will have the full tail seen in previous games, while the female is missing the very tip of it. Generations V and VI would introduce Pokémon with more drastic differences in appearance.

Nidoran

The Nidoran family is a special case in terms of gender. Introduced in Generation I, before gender was known for all Pokémon, Nidoran♀ and Nidoran♂ are considered separate species of Pokémon and indeed have many differences, from appearance to moveset. However, all Nidoran Eggs have a 50/50 chance of hatching into either Nidoran♀ or Nidoran♂, confirming that they are related.

Male	Female
Nidoran♂	Nidoran♀
Nidorino	Nidorina
Nidoking	Nidoqueen

Other

In a manner similar to Nidoran, Eggs produced by Illumise may hatch into Volbeat. While Latias and Latios are in the Undiscovered Group in the games, likely due to being legendary Pokémon, Latias have produced Eggs containing Latios in the anime, confirming that they are similarly related.

Male	Female
Volbeat	Illumise
Latios	Latias

Gender-based evolutions

Some Pokémon may have different ways of evolving depending on their gender. These Pokémon may therefore have one or more evolutions that can only be a single gender.

Pre-evolution	→	Evolved
Kirlia	Male only → Dawn Stone	Gallade
	Either gender → Level 30+	Gardevoir
Snorunt	Female only → Dawn Stone	Froslass
	Either gender → Level 42+	Glalie
Burmy	Male only → Level 20+	Mothim
	Female only → Level 20+	Wormadam
Combee	Female* only → Level 21+	Vespiquen

Other single-gender Pokémon

The following is a list of all Pokémon that are either 100% male or 100% female and have not been mentioned in an above section. In particular, these Pokémon have no explicit relation to a Pokémon of the opposite gender through evolution or breeding.

Trivia

Nidoran♀ and Nidoran♂ show genders twice in Generation II, but only once in Generation III onward

• In Generation II, a Pokémon's gender was determined through its Attack IV. Due to this, unless a Pokémon was a member of an all-female species, such as Nidoran♀ and Smoochum, it could never have a maximized Attack stat, as female Pokémon were given the lower half of the IV range. This also caused the inability for a female Pokémon of a species with a gender ratio of seven males to one female—like the starter Pokémon and Eevee—to be Shiny, due to that also running partly off of the Attack IV. In Generation III this was addressed, with IVs no longer determining either of these, allowing for Pokémon species with two genders to have females with maximized Attack and simultaneously retain its chances of being Shiny.
• Although its English and French names suggest that it is exclusively male, Mr. Mime may be of either gender. This is due to the fact that it was given its name prior to the introduction of gender to the series.
• Since Azurill has a different gender ratio than Marill and Azumarill, one in three female Azurill will be male after evolving into Marill, dependent on the personality value of the Azurill in question.
• In the international versions of Generation II, due to how the battlefield display is programmed, Nidoran♂ and Nidoran♀ have their gender icon shown twice, once in their name, and once after the level. This does not occur in the Japanese and Korean games, however, as the gender icon was present after all Pokémon's names due to the shorter character limit there. This was addressed in all later generations, which prevent the gender icon from showing up when an un-nicknamed Nidoran of either gender is on the field.
