<prompt> The production of mature spermatozoa from spermatogonia:Takes 32 daysTakes 70 daysTakes 150 daysIs unaffected by Kallmanns syndrome  <response>: Ans. B. Takes 70 daysIt takes approximately 65 to 70 days to develop spermatozoa from the earliest stages of spermatogonia. Because the production of sperm depends on LH and FSH, a lack of GnRH Kallmanns syndrome will reduce the production of LH, FSH, and sperm. Temperature is important in regulating sperm production. Optimal sperm production occurs at 2 to 3_C lower than body temperature.
