While I haven't gotten deep in the original game at all, I have noticed how the character (stockly named "Lust") seems to have terrible memories of some of the rooms of the Laboratory (starting area), meaning that the character didn't spend all their time in a test tube, but spent time outside of it and was harshly tested, such a test of "does growth pod humanoids have virginity to take?" doesn't sound such a crazed experiment, considering the fact they made a growth pode humanoid (aka, Lust).
