Higher Human Biology 2.1

As germline cells are diploid, they can either divide by mitosis to form more germline cells and/or divide by meiosis to form haploid gametes. 

The male reproductive organs are the testes. The testes are the site of sperm production. The seminiferous tubules in the testes produce sperm.
