These develop into mature spermatozoa, also known as sperm cells. Sowmya Suresh 15 January at It consists of three phases: By visiting this site you agree to the foregoing terms and conditions. The mature spermatozoa are released from the protective Sertoli cells into the lumen of the seminiferous tubule in a process called spermiation.

Diploid cells in the seminiferous tubules of the testes undergo meiosis to form haploid sperm cells. Including the transport on ductal system, it takes 3 months. Recommended for You Conception.
