The Mystery of Sperm Cells Revealed

A new research study, published in National Geographic News reveals how human males produce 1,500 sperms cells every second. For the past 40 years scientists have thought stem cells in the testes called germline stem cells become sperm only through a simple, two-step process. But the new study reveals for these germline stem cells can become sperm in several different ways, according to new experiments carried out on mice. Since sperm are short-lived, they must constantly be replenished, hence that 1,500-per-second production rate. Unlocking such mysteries of sperm development could someday lead to infertility treatments or even the elusive male birth control pill. Fascinating article and well worth a look.
