Ovoblastic

adj. Of or relating to an egg cell.

Mr Dixon,..took on to ask of Mr Mulligan himself whether his incipient ventripotence,..betokened an ovoblastic gestation in the prostatic utricle.
Ulysses, James Joyce (1922)

All the big words in the above quotation are fun as well. Sprinkle “utricle” into conversation wherever possible.

I know you talk about egg cells on a regular basis, so this will be an especially useful word to you. For me however, I just like to say it because it has “blastic” in it. Sounds dangerous. Like it might blow up at any minute. Resulting, of course, in an egg-splosion.
