Considering its size and likely lifespan It wouldn't surprise me if Zilla was asexual, giving birth to a sole live offspring (no eggs) - making Zilla neither mammal nor reptile, fitting in with its depiction as a 'Titan.'

MemberBaragonSep-24-2018 2:51 PMI actually wrote a summary of how Godzilla's gender has been addressed officially by Toho for Wikizilla. For the sake of simplicity I'll just paste it here, apologies for the wall of text. The important takeaway is that Toho officially classifies Godzilla as a male and always has. Even the 1998 TriStar Godzilla is officially a male even though it can lay eggs. Anyway, here's the summary:
While the Japanese dialogue in the Godzilla films uses gender-neutral pronouns (equivalent to "it") to refer to Godzilla and all the other monsters, official translations of the films, including dubs and subtitle tracks, will often explicitly identify Godzilla as being a male creature. While some translations will still refer to Godzilla as "it," he has never been referred to as a female in any of his onscreen appearances. Further establishing Godzilla's male gender is his official title, King of the Monsters, or Monster King (怪獣王 Kaijū-Ō) in Japanese. This title was first used for Godzilla in the 1956 American re-edit of the original Godzilla film, Godzilla, King of the Monsters! This title has subsequently been applied to Godzilla in both official Japanese and American media, and has become synonymous with the character, even to the point of being trademarked by Toho. Worth noting is that English dialogue even within the Japanese versions of the films will often refer to Godzilla using male pronouns, examples being Godzilla vs. Mechagodzilla II and Godzilla: Final Wars. Officially licensed English-language media, such as the Hanna-Barbera Godzilla cartoon, American Godzilla comics, and the films of the MonsterVerse, all consistently refer to Godzilla as a male, with some of the designers for Legendary Pictures' Godzilla even taking care to make the monster's design appear "masculine."[4]
A common point of confusion that has led some to speculate that Godzilla is female is the presence of his sons, as no mate for Godzilla is ever seen onscreen and only female reptiles can produce eggs. However, Godzilla's son in the Heisei series, Godzilla Junior, is explicitly confirmed to not be Godzilla's biological son, but rather another member of the Godzillasaurus species that Godzilla simply adopted. Godzilla's relation to Minilla, his son in the Showa series and in Godzilla: Final Wars, is unclear, as it is never explained in the films themselves if he is Godzilla's biological child or if he was adopted like Godzilla Junior. Even still, Godzilla is explicitly described as being Minilla's father and not his mother, being referred to as "Papa Godzilla" (パパゴジラPapagojira) in supplementary materials for Son of Godzilla. In addition, the film's director, Jun Fukuda, clarified at the time that the Godzilla featured in the film was in fact male.[5]Furthermore, both the 1998 informational book The Official Godzilla Compendium and Toho's official English-language website state that Minilla was adopted by Godzilla in Son of Godzilla.[6][7]
Another common source of confusion regarding Godzilla's gender comes from the 1998 American Godzilla film directed by Roland Emmerich, which featured an incarnation of Godzilla that lays eggs asexually. Even despite this ability, this version of Godzilla is explicitly referred to as a male in dialogue, with Nick Tatopoulos even calling it "a very unusual he" after discovering its ability to reproduce asexually. The film's official novelization even refers to Godzilla as the "father" of his asexually-produced offspring. This Godzilla's sole surviving offspring from Godzilla: The Series does not retain his father's ability to reproduce asexually, and later mates with a female mutant Komodo dragon named Komodithrax to act as a surrogate father to her offspring. When the original Godzilla returns as Cyber Godzilla in the series, Nick refers to the creature as the other Godzilla's "daddy." The Godzilla featured in Shin Godzilla also possesses the ability to reproduce asexually, but not through the production of eggs. Rather, cells that are removed from Godzilla's body will continue regenerating, potentially growing into fully-functioning organisms and allowing Godzilla to propagate across the globe. In addition, at the end of the film, this Godzilla's next stage of evolution is shown to be a collective of smaller human-sized forms that were frozen while fissioning from the tip of his tail. The same applies to Godzilla Earth from the GODZILLA anime trilogy, whose cells gave rise to an entire ecosystem of organisms possessing his DNA, including another Godzilla dubbed Godzilla Filius.
The Godzilla book written by Ian Thorne also makes the strange claim that "Gigantis," as Godzilla is called in the Americanized version of Godzilla Raids Again, is a female monster. This is most likely just one of the miscellaneous errors contained in the book, as dialogue in Gigantis, the Fire Monster consistently refers to Gigantis with male pronouns.
While a female member of Godzilla's species has never appeared in a film, some have been featured in official non-film media. Examples include Rozan from A Space Godzilla, Bijira and Majira from Gojira-kun: Kaijū Daikōshin, and Gojirin from Get Going! Godzilland. The monster Biollante, spawned partially from Godzilla's own cells, is considered to be a female monster, and she and Godzilla are compared to a "brother and sister" at one point in the film Godzilla vs. Biollante.

MemberAnguirusSep-08-2022 10:36 AMI think showa to heisei its pretty clear hes a guy.and I think maybe zilla can switch genders like some frogs. its millennium-onward where genders start to get a little whacky.
In godzilla 2000 and g vs. megaguirus Im pretty sure hes a guy. and in final wars the xilean laeder says in the english dub : "this godzilla guy is one tough dude" and the way hes portrayed in the kiryu trilogy isnt really that fitting of a female character. so I think hes was thought of as a boy throughout the making of those films. but gmk is quite confusing. since the godzilla in that movie is comprised of a buch of spirits, it might have both male and female spirits within it. so I guess the gmk zilla is a non-binary more-or-less.
the monsterverse godzilla is one hundo' percent male.
godzilla earth is a plant pretty much but if it does have a gender its proly male. shins and sp godzilla might switch genders to when they evolve.
