Morphology
eupyrene = eu + pyrene
Formed from the Greek combining form eu- + pyrene, which are specialised scientific elements unfamiliar to average learners and do not yield the meaning 'normal fertile sperm' transparently.
Etymology
Eupyrene comes from Greek parts eu- 'good', as in euphoria, and -pyrene 'seed'. So it literally means 'good seed', which helps explain why it describes normal, fertile sperm cells in some insects.
