Key Info
  • The process of sperm production
  • Duration: 02:50
  • Michael Mosley explains the process of sperm production. The average man produces 100 million sperm per testicle per day, and each sperm takes approximately 70 days to develop. However, this process is highly inefficient and approximately 85% of sperm produced are faulty in some way. But it is quantity not quality that matters. If a sperm is not ejaculated within about a month they re-absorbed back into the seminiferous tubules. First broadcast on 'Inside the Human Body' on BBC One in May 2011.
