* Normally 80ml is delivered through the [[Female_Reproductive_Tract_-The_Cervix_-_Anatomy_%26_Physiology|cervix]] to reach the [[Female_Reproductive_Tract_-The_Uterus_-_Anatomy_%26_Physiology|uterus]] by gravitational flow.

* Uses 2-3 billion sperm per insemination (60 billion in a normal ejaculate), so is relatively inefficient only giving ~20 inseminations per [[Reproductive_Behaviour_-_Copulatory_Behaviour_-_Anatomy_%26_Physiology#Ejaculation|ejaculate]].
