So we all know about the mnemonic "SEED" for the mesonephric (Wolffian) duct derivatives in the male. However, some sources list these as the mesonephric duct derivates:
Seminal vesicles
Epididymis
Ejaculatory duct
Ductus deferens
And others say:
Seminal vesicles
Epididymis
Efferent ductules
Ductus deferens
Why is there some conflict on ejaculatory duct vs. efferent ductules? Is one source simply leaving out the ejactulatory duct while the other one is considering efferent ductules as part of the epididymis?
