Is infertility part of Darwin's natural selection?
Yes.
Infertility in a small number of individuals of a species simply means that those individuals may not have offspring and pass on their genes; however, if this detrimental genetic change is widespread enough in the species, it could mean that the species as a whole may lose their ability to reproduce in numbers large enough to survive and they might face extinction. Any genetic change that reduces the lifespan of an organism, such that it cannot reach adulthood and reproduce, does relate to natural selection and evolution.
For instance, research from 2014 suggests that the damage to human males' uniquely male "y" chromosomes may have stopped, despite some evidence to the contrary from a few years ago that this might have an impact on human fertility and survival in the long run. https://tutor.hix.ai

Infertility is not typically considered a direct part of Darwin's natural selection process because it reduces an individual's reproductive success. However, certain genetic factors that contribute to infertility may persist in a population if they are linked to other traits that provide a reproductive advantage. Additionally, societal and environmental factors can influence infertility rates and its impact on natural selection.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
