Basics: Guest Post 3: Sperm maturation and ejaculation

What you all were waiting for has finally come! Yeah.
Sperm maturation and ejaculation
OK!! So the last time I was over here at Neurotopia we were talking about sperm in their infancy. We discussed spermatogenesis — how we got from a diploid spermatogonial stem cell to a haploid spermatid — and then spermiogenesis — the process by which the spermatids acquire the features of spermatozoa: tails, acrosomes and the like.
We stopped there when the sperm had just graduated from diapers to their big kid undies, and we’ll pick up where we left off.
