Dessert Nomad
Adventurer
My thing is that the general populace will want to worship fertility deities and, however many dungeons the adventurers go into, it's not quite sense that someone, at some point, wouldn't come from a Deity of Fertility. Indeed, a blighted land could be the ideal spot for one such Cleric to work in: restoring the fertility. The Fisher King is an example of this.
I hadn't considered the Life domain as such, but it does make sense.
It's not a matter of someone at some point coming up with a fertility deity, or what imaginary people in-game might want, it's a matter of whether the people publishing information about the default setting in a game primarily about adventuring decided to spend time and money including a deity specifically about not adventuring. The question in the OP presumes something like 'they must be deliberately avoiding this because its problematic', but it's probably just 'no one's interested enough to include deities that don't do things PCs are interested in.' Also like someone else pointed out, Greyhawk has a fertility deity as do some other pantheons, it's not like all D&D completely avoids the topic.
As far as 'restoring a blighted land', there's already a bunch of deities about nature, agriculture, and healing. If improving the yield of land counts as a 'fertility deity', there's already several in the FR deity lists and I don't think there's been any issues with them being considered problematic.
