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 — […]

What to do…what to do… Nel-Themaat et al. “Quality and freezing qualities of first and second ejaculates collected from endangered Gulf Coast Native rams” Animal Reproduction Science, 2006. Heh. So it turns out that the people who wrote the […]
Hello and welcome to Guest Post TWO! And Sci is so glad that Ambivalent Academic is covering meiosis, because I sure as heck didn’t want to do it. 🙂 Male Reproduction Part II – Spermatogenesis Last we left off we took a basic tour through the male reproductive tract in the way in which a […]
Sci may have hinted that there were guest posts coming up in the near future. After that long series on female reproductive anatomy, Sci thought it would only be fair to let the dudes have some information as well. Unfortunately, Sci’s knowledge of the male reproductive system is related almost entirely to hilarious things like […]
