Formation of cAMP has been studied in neonatal rat testis. In the presence of aminoophylline, LH and PGE1 stimulated cAMP levels during the entire postnatal period. The highest stimulation was found in the testis of 2-day-old rats after-which cAMP synthesis diminished with advancing age. FSH had no stimulatory effect on cAMP level in 5-day-old rats.
