Garrett Wang (Harry Kim) and Robert Duncan McNeill (Tom Paris) did a podcast called The Delta Flyers where they do a full episode-by-episode rewatch of Voyager and often rant about the many problems of the show (and about the bits they enjoyed, as well). Didn’t get through it all, but it was decent travel listening.
Both of them are pretty often annoyed about how their characters (and most of the others) were stuck on a writing treadmill to obey that absurd syndication demand of an eternal moment, such that new viewers can drop in without feeling like they’ve missed anything.
I think the tantric side of Daoist mysticism/alchemy has semen retention as a way of preserving vital energy, but… as to whether that has its own terminology or not I am also not going to investigate.
I did read a few cultivation webnovels a while ago, and I recall a few jokes to the effect of “The great sage has been furiously seeking immortality in his cave for days now”.
