Biological function of testis ketone

Biological function of testis ketone
Testis ketone is principal ingredients of grand sex hormone, the biological effect in the human body is extremely important, mainly have the following aspects: ( 1) In embryo period, testis ketone secretes the peak at pregnant 12- 18 weeks, drops later, reach the lowest level until being born in. ( 2) In man neonatal period, peripheral blood testis ketone level is a peak, to drop to the lowest level again before adolescence. ( 3) Testis ketone level is raised, nearly examined in man adolescence. The raised age of density is 12- 17 years old in testis ketone is in the peripheral blood, the sex function marking the man too at this moment has been already basically ripe, possess ability and sexual behavior of producing the sperm. ( 4) The adult man is during 20- 30 years old, peripheral blood testis ketone level is up to 600 mu; G/dl, is shown that there is fluctuation of rhythm at the same time. Namely there is changing and rhythm change in every day in one year. The annual cycle of adult man's peripheral blood testis ketone level changes the rhythm, it is the highest during autumn, it is 800 mu; g/dl; It is the lowest in spring, it is 600 mu; g/dl. The mechanism that such periodic rhythm changes is not so obvious at present. Every day's periodic rhythm change is the highest in early morning, it is the lowest at night. The pulse-duct secretion of testis ketone is because of urging the corpus luteum to turn into the plain (LH) Causing rhythm institute. ( 5) Man, before 50 year old, testis the intersection of ketone and level has not see, drop, begin, drop after the 50 year old yet, it is generally 500- 200 mu; g/dl; Think, testis ketone level increases the reason dropped with age gradually at present, may have relations with reduction of cells of thunder.
