The production of mature spermatozoa from spermatogonia:: (A) Takes 32 days, (B) Takes 70 days, (C) Takes 150 days, (D) Is unaffected by Kallmann's syndrome
Answer is B. 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 (Kallmann's 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.
