<prompt> The production of mature spermatozoa from spermatogoniaTakes 32 daysTakes 70 daysTakes 150 daysIs unaffected by Kallmanns syndrome  <response>: It 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 impoant in regulating sperm production. Optimal sperm production occurs at 2 to 30C lower than body temperature.
