I'm trying to prepare material for 'the talk' about sex and reproduction. I know there's plenty of great books and resources out there for young readers, which I'll use to start with, but I'm also looking for something overbearingly scientific.
Essentially, I'm looking for an academic-level resource that is as close as possible to a literal play-by-play second-by-second explanation of puberty and the entire reproductive cycle. This is partly to polish my understanding, and to prepare myself for unexpected questions.
For example, it should explain the mechanics that sperm/egg cell(s) use to get around, how sperm penetrates the ovum, the process of breast development, and how they become lactation-ready, how the milk is made, what controls where adult body hair grows, the chemical process leading to feelings of lust, etc.
I was mentally reviewing my knowledge of this the other day and realized I know a lot of 'what' but not 'how' or 'why', so here I am.
Multiple books/resources is fine.
