Approximately how many sperm are produced by the testes each day?

1. Sperm production is continuous and occurs at extremely high volume compared to female gamete production. 2. A specific daily output range for men. 3. This range is 100 to 300 million sperm per day. 4. 1 to 5 million and 500,000 to 1 million are both different figures a reader might guess from memory, but neither matches the specific figure given here. 5. 1 to 2 billion is also incorrect for the same reason: it does not match the specific figure given here. 6. This contrasts sharply with women, who typically ovulate only one oocyte per month. _Source: OpenStax Anatomy and Physiology (CC BY 4.0), Ch 27 "The Reproductive System", p.1284 §Structure of Formed Sperm_
