Compound Noun (Abstract): "Paternal age effect" is an abstract compound noun because it refers to the observed relationship between the father's age at conception and an increased risk of certain genetic mutations or health conditions in the offspring. It is a scientific and medical concept — intangible and statistical in nature.

It is countable: “Several paternal age effects have been documented in psychiatric research.”
