title: [Quantitative variations in the plasma testosterone in male pigs, from birth to adult].
abstract: Testosterone peripheral venous blood level in newborn piglet shows a large rise after birth with a maximum level between days 5 and 17. Except for a peak between days 35 and 45, values decrease regularly during the first six weeks, then stay low during the third month. From the fourth to the sixth month, testosterone level progressively increases (onset of puberty). After a larger rise between 180 and 200 days (period when sexual behavior begins), testosterone plasma level increases to reach adult values. According to these observations, the androgenic function in pig presents some analogy with man.
